Description

[Detailed Description of the Invention] [Summary] A method for displaying the serial number of each layer board constituting a multilayer board, which is a method for displaying the serial number of each layer board of a multilayer board using a numerically controlled drilling machine (NC drilling machine). In the opening process, by simultaneously drilling holes corresponding to the code number that represents the manufacturing number of each layer board in binary numbers and the pattern of flower characters that can be visually identified, it is possible to identify the various types of boards during the manufacturing process. This makes it possible to improve efficiency and visually distinguish.

[Industrial application field]

The present invention relates to a display method for a multilayer board, and more particularly, the present invention relates to a display method for a multilayer board, in which a code number corresponding to the manufacturing number, a visually distinguishable flower character, and two perforation displays are displayed simultaneously with the through-hole drilling process of the multilayer board. Regarding the method.

When manufacturing many types of multilayer substrates, each type is managed and distinguished by a serial number assigned to each type to prevent confusion. Note that the serial number is written on each board by an operator using a ruled line, and as a result, human errors often occur, causing confusion in the manufacturing process and reducing work efficiency.

Therefore, there has been a demand for a display method that can automatically visually identify each board and display a stable serial number.

[Conventional technology]

FIG. 4 is a block diagram for explaining a conventional display method for a multilayer board.

In FIG. 4, each of the intermediate layers 1-2 of the multilayer board is marked by an operator writing in the corresponding manufacturing number using a ruled line in the manufacturing number displaying steps 2-1 to 2-n, and each layer on which the manufacturing number is written. Through-hole holes are formed in each of the substrates in through-hole forming steps 3-1 to 3-n, and a pattern of an intermediate layer substrate is formed.

When the pattern formation of the intermediate layer substrate is completed, the fifth
As shown in the schematic diagram of the multilayer substrate in the figure, in the surface alignment step 4, the uppermost layer substrate 1-1 and the lowermost layer substrate 1-n
Insert intermediate layer 1-2 between and align the surfaces.
After lamination, in the manufacturing number display step 5 on the uppermost layer, an operator writes the corresponding manufacturing number N on the surface of the uppermost layer substrate using a ruled line.

The multilayer substrate with the serial number written thereon undergoes various steps after through holes are drilled at positions that match the through holes 7-1 to 7-n of the intermediate layer substrate 1-2 in the through hole drilling step 6. It will be completed after a while.

[Problem to be solved by the invention]

In this conventional method, all the serial numbers for classifying and displaying the substrates of each layer are entered by an operator using a ruled line.

This scribing work induces human error, and the classification display often differs from the actual product.
In addition, since the thickness of each layer of the board is extremely thin at around 0.1 m/m, it takes time to do the marking work, and
Since the work is detailed, there is a problem in that workers become fatigued and work efficiency decreases.

The present invention was created in view of these points, and in the through-hole drilling process, a code number hole corresponding to the serial number is created using an NC drilling machine.
The object of the present invention is to provide a display method for a multilayer substrate in which a visually distinguishable flower character hole is formed in each layer of the multilayer substrate.
