JP4830767B2 - Method and program for creating quality display data of component mounting board - Google Patents

Description

  The present invention relates to an automatic appearance inspection performed on a component mounting board, a method for automatically creating data representing quality guaranteed by the inspection (hereinafter referred to as “quality display data”) by a computer, and The present invention relates to a program used in the method.

  In recent international quality standards, it is obliged to submit a list (hereinafter referred to as “quality assurance list”) in which the quality of each part of the product is divided into various items (for example, TS16949). . When a component mounting board is incorporated in a product, it is necessary to create a quality assurance list indicating data representing the quality of each component mounted on the board.

  When automatic appearance inspection is performed on each component of a board, generally, a plurality of inspection areas are set in a range including the component and its surroundings (such as lands), and predetermined setting data (implemented for each inspection area). Type of inspection and its inspection criteria). For this reason, when creating a quality assurance list based on the automatic visual inspection of the board, after listing the parts mounted on the board individually, what purpose is in each inspection area for each part? It is necessary to confirm whether or not the inspection is carried out and combine the confirmation contents into one.

  In the above operation, the list of mounted parts can be specified using the CAD data or inspection data of the board. Also, the contents of the inspection performed on each part can be extracted from the inspection data and displayed or output (see Patent Document 1).

JP-A-8-321700

  However, the user must determine what inspection is performed on each part and what quality is guaranteed by the inspection. In particular, there are a wide variety of types of inspections, and even for the same type of parts, the settings may differ depending on the relationship with surrounding parts, so it is necessary to check the contents of each part individually. In addition, the burden on the substrate manufacturer is significant.

  This invention pays attention to the above-mentioned problem, and it is an object to enable a computer to automatically create quality display data representing the quality of a component guaranteed by an automatic appearance inspection for each component on a component mounting board. It is what.

  In order to solve the above-described problems, the following first to fourth steps are performed in a method of creating quality assurance data related to the execution of automatic visual inspection by a computer.

  In the first step, for a plurality of inspection purposes, for each inspection region set on the substrate, based on setting data determined for the inspection, execution indicating whether or not the inspection corresponding to the purpose is performed Create status data. In the second step, a logical product is obtained for each part of the implementation status data created in the inspection area of the land among the implementation status data created in the first step. In the third step, the first of the components on the board is calculated. The implementation status data of the logical product obtained in two steps and the implementation status data created in the first step for the inspection area other than the land are integrated for each inspection purpose. Further, in the fourth step, for each part, data in which the combination of the implementation status data integrated in the third step is associated with the part identification data is generated and output as quality display data.

  The “plurality of inspection purposes” referred to in the above method is, for example, detection of component mismounting, component shift detection, and component connection failure detection. The inspection area is preferably provided for each part in the vicinity of the part, such as the main body of the part, electrodes, and lands, but an inspection area including the entire part may be set.

  According to the above method, after the data indicating whether or not the inspection corresponding to the purpose is performed is created for each inspection area for each inspection purpose based on the setting data determined for the inspection. These implementation status data are collected in units of parts and output in association with the part identification data. Therefore, it is not necessary to confirm the contents of the inspection for each part in order to create the quality assurance list for the board, and the time required for creating the list can be greatly reduced.

  Also, since most parts are connected to multiple lands, it is necessary to perform inspections on all lands to ensure that inspections corresponding to a certain purpose have been performed on the lands. . In view of this point, in the above second step, for the implementation status data created for the inspection area of the land, the logical product is obtained for each part, so based on the inspections performed for all lands, The content of the final quality display data can be determined.

  In one aspect of the above method, the setting data defined for each inspection region includes data indicating an inspection that can be performed in the inspection region and flag data indicating whether or not the inspection is to be performed. In this case, in the first step, the inspection purpose of the inspection included in the setting data is specified based on a table in which various inspections are classified for each inspection purpose, and the specified inspection purpose is determined based on the flag data in the setting data. Determine the value of the corresponding implementation status data.

  According to said aspect, about the test objective in which the test | inspection which can be implemented is set, the value of implementation status data can be determined easily based on the flag data corresponding to the test | inspection. In addition, even for inspection purposes for which no feasible inspection is set, the value of the implementation status data can be easily determined if the inspection for that purpose is not set (a value indicating that no inspection is performed). Can be.)

  In a further preferred aspect, when a plurality of inspections that can be performed for the same inspection purpose are set in the setting data, the logical sum or logical product of the flag data corresponding to these inspections is obtained and the operation result is obtained. Is the implementation status data for the inspection purpose corresponding to each inspection.

  According to the above aspect, when the standard to be followed by the manufacturer of the substrate or the standard set by the manufacturer is "if the inspection is not performed, it cannot be said that the quality can be guaranteed". Obtains the logical product of each flag data, and if “one of the tests only needs to be executed”, the logical sum of the flag data can be obtained. Therefore, it is possible to flexibly cope with standards required for quality assurance.

  A program for creating quality display data relating to the inspection of the component mounting board causes the computer to execute the first to fourth steps. Of these, the program for the first step can include a program for executing the above-described aspects.

  According to the above method and program, quality display data representing the quality guaranteed by the inspection can be automatically created by the computer based on the data set for the automatic appearance inspection of the substrate. Therefore, the burden on the creator of the quality assurance list can be greatly reduced, and errors in the list can be prevented.

FIG. 1 shows the configuration of an automatic visual inspection apparatus for printed circuit boards to which the present invention is applied.
This automatic appearance inspection apparatus (hereinafter simply referred to as “inspection apparatus”) is for inspecting the quality of each component on a board that has undergone a reflow process, which is the final process of the board production line. The camera 2, the illumination device 3, the substrate stage 4, the input unit 5, the monitor 6 and the like are configured.

  The substrate stage 4 includes a table unit 41 for supporting the substrate 8 and a moving mechanism 42 including an X-axis stage and a Y-axis stage (both not shown).

  The camera 2 and the illumination unit 3 constitute an optical system called “color highlight method”. The camera 2 generates a color still image, and is provided above the substrate stage 41 with the imaging surface directed downward and the optical axis aligned with the vertical direction. The illumination unit 3 includes three annular light sources 3R, 3G, and 3B disposed between the substrate stage 4 and the camera 2. These light sources 3R, 3G, and 3B emit red, green, and blue color lights, respectively, and are arranged in a state in which each central portion is aligned with the optical axis of the camera 4. The light sources 3R, 3G, and 3B are set to have different diameters so that the substrate 4 can be irradiated with light from different directions.

  The controller 1 includes a computer control unit 10, an image input unit 11, an imaging control unit 12, an illumination control unit 13, an XY stage control unit 14, a memory 15, a CD-ROM drive 16, and a communication interface 17. It is done. The image input unit 11 includes an interface circuit for the camera 2 and the like. The imaging control unit 12 is for outputting a timing signal instructing imaging to the camera 2.

  The illumination control unit 13 controls the operation of turning on / off the light sources 3R, 3G, and 3B of the illumination unit 3 and adjusts the amount of light. The XY stage control unit 14 controls the movement timing and movement amount of the substrate stage 4.

  The memory 15 stores an inspection program and an inspection data file 101 to be described later. Further, the memory 15 of this embodiment also stores a program constituting a quality display data creation system 100 described later.

  The inspection data file 101 stores inspection area setting data for each component (indicating the position and size of the area) and inspection data for each inspection area. The inspection data is set by a user (a board manufacturer and a quality assurance list creator), and is data (in this specification, “inspection” indicating inspections that can be performed in the corresponding inspection area. And flag data (hereinafter referred to as “inspection item flag”) indicating whether or not the inspection is to be performed. Furthermore, for inspections for which the inspection item flag is set to ON, inspection reference values such as a binarized threshold value for detecting a region to be inspected and a pass / fail judgment reference value are also included in the inspection data.

  The control unit 10 controls the movement of the substrate stage 42 via the XY stage control unit 14, thereby aligning the camera 2 and the substrate 8 and taking an image. The color image generated by this imaging is input to the control unit 10 via the image input unit 11 and stored in its internal memory (RAM). The control unit 10 sequentially inspects each part using the data registered in the inspection data file 101 for each part of the color image stored in the RAM. Further, the control unit 10 transmits the measurement result and determination result for each component and the image used for the inspection to an external device (not shown) using the communication interface 17.

  In the above inspection apparatus, a plurality of inspection regions (hereinafter referred to as “windows”) are set for each mounted component of the board, and individual inspection data is set for each window for inspection.

  FIG. 2 is a table in which various inspections performed by this inspection apparatus are classified based on the inspection purposes. This table is provided with four types of name classifications of “false mounting”, “deviation”, “short”, and “open”, and the names of inspection items belonging to the classification are associated with the respective categories. In addition, according to the inspection item, it is possible to specify the contents of a series of processes (detection, measurement, determination, etc. of a region to be inspected) necessary for the corresponding inspection.

  “Incorrect mounting” is an inspection intended to detect component mounting errors, and two types of inspection items “mounting” and “OCR” are assigned. The “deviation” is an inspection for the purpose of detecting the deviation of components, and inspection items “angular deviation”, “X deviation”, and “Y deviation” are assigned.

  “Short” is an inspection for the purpose of detecting a short circuit between components, and an inspection item “bridge” is assigned. “Open” is an inspection intended to detect a connection failure between an electrode on the component side and an electrode (land) on the substrate side. Each inspection item of “wetting”, “fillet”, and “electrode detection” is assigned to this classification.

FIG. 3 shows an example of setting a window for a part. In this figure, with respect to the two chip parts C _A and C _B arranged vertically, illustration of lands and fillets is omitted and various window setting states are shown. In the drawing, characters are written on the main body of the lower chip part C _B , but no letters are written on the upper chip part C _A.

In this embodiment, each of the parts C _A and C _B is provided with a part body window having a size that encompasses the whole part. However, the component body window functions not as a window for inspection but as a reference window for setting other windows.

Further, in each of the parts C _A and C _B , a land window is set at each land position on both sides of the part. In this land window, it is possible to perform inspections for each category of “shift”, “short”, and “open”. In the “deviation” inspection, the edge of the part is detected based on the color in the window, and the suitability of the angle or position of the part is determined using the detection result. In the "short" and "open" inspections, the position and size of the color areas (red, green, and blue areas) corresponding to each light source are detected using the characteristics of the color highlight method described above. Based on the detection result, the presence / absence of a bridge and the suitability of the solder shape are determined. Note that “wet” and “fillet” are targets to be implemented in the land window for “open”.

  In the mounting window and the OCR window, inspections belonging to the first classification “misinstallation” can be executed. Each window is set at a position corresponding to the main body of the component, and the size is almost the same.

  In the mounting window, it is possible to carry out an inspection (mounting inspection in FIG. 2) for the purpose of detecting erroneous mounting of components by the colors in the window. In the OCR window, it is possible to detect a character string in the window and perform an inspection (OCR inspection in FIG. 2) for the purpose of detecting an erroneous mounting of a component depending on the suitability of the character string. As shown in FIG. 3, a mounting window needs to be set for a component for which no character string is displayed. An OCR window is generally set for a part displaying a character string, but both OCR and mounting windows may be set.

In the bridge window, the inspection belonging to the third classification item “short” can be executed. In this window, similarly to the inspection performed in the land window, the color in the window is used to determine whether or not a solder bridge is formed between adjacent parts. This bridge window can be set for one or both of the parts C _A and C _B.

  Although not shown in FIG. 3, an electrode detection window may be set at a position corresponding to the component-side electrode. In this window, “electrode detection” inspection belonging to “open” can be performed.

  The inspection data file 101 stores setting data related to the window corresponding to each component on the board. Further, for each window, an inspection item flag is set for each inspection item that can be performed in the window. For items for which inspection is performed, the corresponding inspection item flag is “ON” (value is “1”), and for items for which inspection is not performed, the corresponding inspection item flag is “OFF” (for value) “0”).

  Setting of the window and the inspection item flag is performed by the user of the inspection apparatus prior to the inspection. This setting process may be performed using reference inspection data (library data) registered in advance in the apparatus, or may be performed manually. Even for the same type of component, different settings may be made depending on the size of the land and the surrounding mounting density.

  In the inspection apparatus of this embodiment, quality display data indicating the quality guaranteed by the inspection corresponding to the four types of classification shown in FIG. 2 is created for each component on the board. The created quality display data is displayed on the monitor 6 and also output to an external device (for example, a personal computer) via the communication interface 17. Therefore, the user can create a quality display list as shown in FIG. 4 by adding inspection status data other than the automatic appearance inspection to the output data.

  The list in FIG. 4 has a configuration in which, for each part, the part code and the part number are associated with a mark XX indicating whether or not various inspections are performed with contents satisfying the criteria. The range enclosed by the dotted line is based on the quality display data created by the inspection apparatus. A mark indicates that an inspection satisfying the standard is performed for the corresponding item, and a mark X indicates that an inspection satisfying the standard is not performed.

  FIG. 5 shows the configuration of the quality display data creation system. This system includes an inspection data file 101, an inspection data reading unit 102, an initial data creation unit 103, a land unit data integration unit 104, a part unit data integration unit 105, a condition input unit 106, and a result output unit 107. . Among these, the substance of each processing unit excluding the inspection data file 101 is a control unit that executes a program for the processing.

  The inspection data reading unit 102, for each component on the board, from the inspection data file 101, the identification data of the component (such as an identification code and product number individually assigned to the component), window setting data, and each window Read the set inspection items and inspection item flags. The data read here is provided to the initial data creation unit 103. The land unit data integration unit 104 and the component unit data integration unit 105 are provided with the number of settings based on the window setting data, and the result output unit 107 is provided with identification data of each component.

  The initial data creation unit 103 creates initial values of implementation status data corresponding to the four types of classification for each window set for each component based on the data supplied from the inspection data reading unit 102 (hereinafter referred to as this). (Referred to as “initial implementation status data” or “initial data”). In this process, the table corresponding to the examination that can be performed in each window is determined with reference to the table shown in FIG. Then, for the classification that does not correspond, the initial data is unconditionally set off, and for the corresponding classification, the value of the initial data is determined by the following method.

  Similar to the inspection item flag, the implementation status data is flag data indicating whether or not the inspection is performed, and a value can be determined according to the inspection item flag of the corresponding inspection item. If there is one inspection item set for a certain category here, the same value as the inspection item flag may be set in the initial data, but if multiple inspection items are set, The logical sum or logical product of the corresponding inspection item flags is obtained, and the operation result is used as initial data.

  The condition input unit 106 is for inputting a condition for determining a value of initial data when there are a plurality of inspection items that can be performed. This condition is expressed as a condition for assuring that the classification of the plurality of inspection items that can be performed is performed. Specifically, in order to guarantee the content of the inspection, an option (hereinafter, referred to as “AND condition”) that all the inspection items that can be executed need to be executed, and the inspection item that can be executed. Is presented to the user as an option (hereinafter referred to as an “OR condition”) that at least one of them should be implemented.

  The user can select a condition for each window and each classification based on a predetermined standard or a standard determined by the user. For example, in the case of a land window, an OR condition of “angular deviation”, “X deviation”, and “Y deviation” is selected for “deviation”, and AND conditions of “wetting” and “fillet” are selected for “open”. be able to.

  When the AND condition is selected, the initial data creation unit 103 obtains a logical product of the inspection item flags of each target inspection item, and when the OR condition is selected, the initial data creation unit 103 performs a logical sum of the inspection item flags. Ask for.

  The land unit data integration unit 104 integrates the implementation status data created by the implementation status data creation unit into data corresponding to the land window. The component unit data integration unit 105 takes in the implementation status data integrated for each land and other implementation status data and integrates them into one data. Hereinafter, the implementation status data integrated by the land unit data integration unit 104 and the component unit data integration unit 105 may be referred to as “post-integration data”.

  The integration processing in the land unit data integration unit 104 and the component unit data integration unit 105 is performed for each classification item. The final implementation status data integrated by the component unit data integration unit 105 is passed to the result output unit 107. The result output unit 107 creates data in which the integrated data of each item is associated with the part code and the part number for each part, and outputs this as quality display data to an external device or the like.

  FIG. 6 shows changes in the contents of the implementation status data of four types of classification items, taking as an example a component in which a component main body window, a land window, and a mounting window are set. (A) in the figure is a table of initial implementation status data created by the initial data creation unit 103, (B) is a table containing integrated data by the land unit data integration unit 104, and (C) is The final integrated data created by the component unit data integration unit 105 is shown respectively.

  Hereinafter, the flow of processing for creating the implementation status data will be described with reference to FIGS. Note that these drawings show processing for one component on the board, and it is necessary to execute the same processing for each component. In any of the flowcharts, a counter for specifying a window set for a component is i, and a counter for specifying a classification item is j. Further, ST in each figure is an abbreviation for STEP.

  FIG. 7 shows the flow of processing for creating initial implementation status data. In this process, first, in ST1, the total number W of windows set for the component to be processed and the number N of inspection items (N = 4 in the example of FIG. 2) are acquired.

  The initial implementation status data is expressed as a function having a window counter i and a classification counter j as arguments. In ST2, all implementation status data represented by this function is initially set to “off” (value is “0”).

  In ST3, an initial value “1” is set in the counter i. In ST4, inspection data is acquired for a window (for example, a component main body window) specified by i.

  In ST5, an initial value “1” is set in the counter j, and the following processes in ST6 to 10 are executed for the classification specified by j (“misinstalled” in the case of the example in FIG. 2). .

  In ST6, it is checked whether or not an executable inspection item is set for the jth classification in the window under consideration. If this determination is “YES”, the process proceeds to ST7, and the inspection item flag of the inspection item is checked.

  Here, if there is an inspection item flag set to ON, the process proceeds to ST8, and it is checked which of the AND condition and the OR condition is selected. If the user has selected the AND condition, the process proceeds to ST9, and it is checked whether or not the inspection item flag is “ON” for all the inspection items that are set. If this determination is “YES”, the process proceeds to ST10, and the initial data of the j-th classification is changed from “off” set in ST2 to “on”. On the other hand, if any one of the inspection item flags is “OFF”, ST10 is skipped.

  On the other hand, when the user has selected the OR condition, the process proceeds from ST8 to ST10, and processing for changing the initial data to “on” is performed. Even when there is only one inspection item that can be implemented, it is considered that the OR condition has been selected, and the process of ST10 is executed.

  Thereafter, the counter j and i are incremented to N and W, respectively, and the same processing as described above is executed for each combination of i and j. As a result, initial data (contents corresponding to FIG. 6A) can be created for each classification for all windows set as parts.

  The execution status data for each window set by the above processing indicates, for each window, whether or not each class is being executed at a level that can guarantee the target inspection.

  FIG. 8 shows a procedure of processing for integrating data corresponding to the land window among the implementation status data created by the above processing.

  In the first step ST101, the number R of land windows and the number N of inspection items of the part under consideration are acquired. Next, in ST102, for all classifications, the initial value of the post-integration data of the lands (a collection of implementation status data for each land window) is set to “ON”.

  Thereafter, in ST103 and 104, counters j and i are set to the initial value “1”, respectively. In the next ST105, the setting value of the initial data of the j-th classification in the i-th land window is acquired, and the setting value is checked.

  If the above data setting is “ON”, ST106 becomes “YES”, the process proceeds to ST107, and the counter i is incremented. Thereafter, the process returns to ST105 via ST109, and the same processing as described above is executed for the land window specified by the updated i.

  However, if the implementation status data is set to “OFF” for any of the land windows, ST106 becomes “NO” and the process proceeds to ST108, and the implementation status data after integration relating to the jth classification is displayed. Change from “on” to “off”. Thereafter, the process goes through the loop of ST105 to 109 and proceeds to ST110.

  In ST110, the classification of the target object is changed by updating the value of j. Thereafter, the process returns to ST104 and the same processing as described above is executed.

  In the above processing, for each classification, a logical product of initial data for each land window is obtained, and this is set as implementation status data after integration. This is substantially the same as the processing procedure executed in ST8, 9, and 10 in FIG. By this processing, the implementation status data is changed to the contents as shown in FIG.

  The reason for obtaining the logical product of the initial data in the above-mentioned data integration processing for each land is that the inspection of the lands is not completely conducted unless the conditions can be cleared in all windows. This is because the quality cannot be guaranteed. For example, in the case of a square chip, there are lands on the left and right sides of a component. However, when performing a “deviation” inspection, even if only one land window is inspected, there is a possibility that the deviation amount cannot be measured sufficiently. In addition, regarding the “open” and “short” inspection, it is impossible to say that the connection state of the components is good unless it is confirmed that there is no defect in all the land windows.

  FIG. 9 shows a processing procedure for integrating implementation status data in parts. First, in ST201, which is the first step, the total number W of windows, the total number R of land windows, and the number N of inspection items are acquired.

  Subsequently, in ST202, after the integrated data of the classification unit is initially set to “OFF” for all classifications, initial values “1” are set to the counters j and i in ST203 and 204, respectively.

  In ST205, a setting value for the j-th implementation status data of the i-th window is acquired and the value is checked. As a result of this check, if the data setting is not on, ST206 becomes “NO”, and the target window is changed by updating the value of i in ST207. Thereafter, the process returns to ST205 via ST208.

  Thereafter, the same check is performed for each window. As a result, if the jth implementation status data in any window is set to ON, ST206 becomes “YES” and the process proceeds to ST209. In ST209, the post-integration data of the jth classification is changed from “off” set in ST202 to “on”.

  In ST205, initial data is acquired for windows other than the land window, but for the land window, data integrated by the processing of FIG. 8 is acquired. Therefore, if the process of ST209 is not performed, the loop of ST205 to 208 ends when the counter i exceeds (W−R + 1).

  In ST210, the classification of the target object is changed by updating the value of j. Thereafter, the same processing as described above is executed until the value of j exceeds N.

  In the above processing, for each classification, the data after integration of the land window and the initial data of other windows are obtained, and the logical sum of them is obtained and set as implementation status data after integration. Through this process, implementation status data integrated in part units (corresponding to FIG. 6C) can be created.

  In the above-mentioned integration processing for each part, the logical sum, not the logical product of each data, is obtained because the purpose of the inspection and the window setting are in a corresponding relationship, and the higher-level inspection that can be performed in all windows This is because there is no. However, in order to improve the accuracy of the integration process, it is not such an OR operation. Specifically, for each classification, a window in which the implementation status data should be turned on is specified, and the ON / OFF state of each data is determined. When the relationship with the window is correct, the post-integration data may be turned on.

  Also, in this integration process for each component, when inspection items belonging to the same classification are set between a plurality of windows, the logic of the implementation status data for each window is set according to the conditions selected by the user. A sum or logical product may be obtained. For example, if an electrode detection window is set in addition to the land window as a window that can be used for the “open” inspection, this “open” includes the execution status data integrated between the land windows. The logical sum or logical product with the implementation status data set in the electrode detection window may be obtained, and the result may be integrated data for each part.

  Conventionally, when a user creates a quality display list for automatic appearance inspection of a component-mounted board, it is carried out for each part by checking the list of parts on the board and the list of inspection data for each part. It was necessary to check the inspection contents. For this reason, it takes a lot of time and errors may occur. On the other hand, according to the quality display data creation system 100 described above, based on the setting data of the window registered for the inspection and the inspection item flag, data indicating the implementation status of the inspection corresponding to each classification is automatically generated. be able to.

  Therefore, the user edits the quality display data output from the system by using spreadsheet software or the like, arranges the form into a form, or adds other data (for example, manual inspection data shown in FIG. 4). For example, an accurate quality display list can be created simply by processing the output data. Therefore, the efficiency and accuracy of work are greatly improved.

  In the above-described embodiment, the AND condition and the OR condition are set when determining the value of the initial implementation status data. However, complex conditions may be set for setting individual inspection item flags. For example, if more detailed items are set for an inspection item, a condition is set for the selected item, and the inspection item flag is turned on when a detailed item that satisfies the condition is selected. It may be set. In addition, it is also possible to set indispensable fine items that must be selected as conditions, and set the inspection item flag on only when the fine items are selected.

  In the above embodiment, the quality display data is created in the inspection apparatus. However, the present invention is not limited to this, and the inspection data file 101 may be transplanted to an external apparatus such as a personal computer and the quality display data may be created in the apparatus. Good.

  Next, since it is necessary to ensure that the above quality display data is sufficiently inspected, it is desirable to be able to check in advance whether there is any defect in the base inspection data. . For example, the inspection level data may be obtained for each part, and the result may be output to allow the user to confirm.

  FIG. 10 shows an example in which the ratio of the number of inspection items in which the inspection item flag is set to the total number of inspection items set is obtained as level data, and the result is displayed on the monitor. In this example, a schematic diagram of the substrate is shown, and the level of the inspection to be performed is displayed as a percentage on each component on the schematic diagram. The color of the area where each numerical value is displayed is color-coded according to the numerical value.

  According to such a display, the user can easily grasp a low-level component by color or numerical value and review the inspection data of the component to increase the level. Therefore, it is possible to create a quality display list after performing an inspection that can ensure sufficient quality for each component.
