しかしながら、これらの多層配線板にあっては、ノイズ対策として接地パターンが広域に形成される。この接地パターンと熱容量の大きな電子部品とを半田接続によって実装する際には、前記接地パターンの熱容量も大きいため、半田を溶解させるための大きな熱量が必要となり、半田接続する工程に時間を要してしまうといった問題があった。   However, in these multilayer wiring boards, a ground pattern is formed over a wide area as a noise countermeasure. When this ground pattern and an electronic component having a large heat capacity are mounted by solder connection, since the heat capacity of the ground pattern is large, a large amount of heat is required to dissolve the solder, and the solder connection process takes time. There was a problem such as.

そこで本発明の目的とするところは、上述した問題に着目してなされたものであって、短時間にて半田接続可能な多層配線板を提供することにある。   Accordingly, an object of the present invention is to provide a multilayer wiring board that can be soldered in a short time, and has been made paying attention to the above-described problems.

本発明の多層配線板は、請求項1に記載したように、表層や内層に所定の配線パターンが形成され、表層に複数の電子部品を備える多層配線板であって、所定の電子部品の接地側端子と表層側接地パターンとを接続するための接地電極部と、前記接地電極部の近傍に前記表層側接地パターンの一部を切り欠いたスリット部と、前記表層側接地パターンと内層に設けられる内層側接地パターンとを接続する接続部と、を備え、前記接続部は、前記接地電極部と前記スリット部との間に備えてなることを特徴とする多層配線板。 The multilayer wiring board of the present invention is a multilayer wiring board having a predetermined wiring pattern formed on a surface layer or an inner layer and having a plurality of electronic components on the surface layer, as described in claim 1, A ground electrode portion for connecting the side terminal and the surface layer side ground pattern; a slit portion in which a part of the surface layer side ground pattern is cut out in the vicinity of the ground electrode portion; and the surface layer side ground pattern and the inner layer. A multilayer wiring board comprising: a connecting portion for connecting to the inner layer side ground pattern, wherein the connecting portion is provided between the ground electrode portion and the slit portion .

また、請求項2に記載したように、請求項1に記載の多層配線板において、前記スリット部は、前記接地電極部を不連続に囲むように設けられてなることを特徴とする請求項1に記載の多層配線板。   Moreover, as described in claim 2, in the multilayer wiring board according to claim 1, the slit portion is provided so as to discontinuously surround the ground electrode portion. A multilayer wiring board according to 1.

本発明は、表層や内層に所定の配線パターンが形成され、表層に複数の電子部品を備える多層配線板に関し、短時間にて半田接続可能な多層配線板となる。   The present invention relates to a multilayer wiring board in which a predetermined wiring pattern is formed on a surface layer or an inner layer and a plurality of electronic components are provided on the surface layer, and the multilayer wiring board can be soldered in a short time.

以下、本発明が適用された実施の形態について添付図面を用いて説明する。   Embodiments to which the present invention is applied will be described below with reference to the accompanying drawings.

本発明の多層配線板は、比較的に熱容量の大きな電子部品(所定の電子部品)の実装箇所において、図1,2に示すように、ランド1と、スリット部2と、スルーホール(接続部)3と、を備えている。また、多層配線板は、表層(表面側層)や内層に銅箔からなる所定の配線パターンが形成され、表層に電解コンデンサ4や抵抗体など図示しない多種の電子部品を実装してなる。   As shown in FIGS. 1 and 2, the multilayer wiring board of the present invention has a land 1, a slit portion 2, and a through hole (connection portion) at a mounting location of an electronic component (predetermined electronic component) having a relatively large heat capacity. 3). In addition, the multilayer wiring board is formed with a predetermined wiring pattern made of copper foil on the surface layer (surface side layer) or the inner layer, and various electronic components (not shown) such as an electrolytic capacitor 4 and a resistor are mounted on the surface layer.

ランド1は、電解コンデンサ(所定の電子部品)4の端子41を半田接続により実装するために多層配線板の表層に設けられる。ランド1は、電解コンデンサ4の電源側端子41と電源側の配線パターン5とを接続する電極部11と、電解コンデンサ4の接地側端子42と接地側の配線パターン(以下、接地パターンと記す)6と接続する接地電極部12と、を設けている。   The land 1 is provided on the surface layer of the multilayer wiring board in order to mount the terminal 41 of the electrolytic capacitor (predetermined electronic component) 4 by solder connection. The land 1 includes an electrode portion 11 for connecting the power supply side terminal 41 of the electrolytic capacitor 4 and the wiring pattern 5 on the power supply side, a ground side terminal 42 of the electrolytic capacitor 4 and a wiring pattern on the ground side (hereinafter referred to as a ground pattern). 6 and a ground electrode portion 12 to be connected to 6.

スリット部2は、接地電極部の近傍に多層配線板の表面側に設けられる表層側接地パターン61の一部を切り欠いて設けられる。スリット部2は、この場合、接地電極部12を不連続に囲むようにして「L」字状の非銅箔形成領域が2つ設けてなる。   The slit portion 2 is provided by cutting out a part of the surface layer side ground pattern 61 provided on the surface side of the multilayer wiring board in the vicinity of the ground electrode portion. In this case, the slit portion 2 is provided with two “L” -shaped non-copper foil forming regions so as to surround the ground electrode portion 12 discontinuously.

スルーホール3は、接地電極部12とスリット部との間における表層側接地パターンにおいて、この表層側接地パターン61と、多層配線板の内層に設けられる内層側接地パターン62と、を電気的に接続するように設けられる。なお、スルーホール3は、円形または四角など適宜な形状及び寸法は0.3〜1mm等様々なものが適用できる。   The through hole 3 electrically connects the surface layer side ground pattern 61 and the inner layer side ground pattern 62 provided in the inner layer of the multilayer wiring board in the surface layer side ground pattern between the ground electrode portion 12 and the slit portion. To be provided. The through-hole 3 can be applied in various shapes such as a circle or a square and a suitable shape and size such as 0.3 to 1 mm.

斯かる多層配線板は、表層や内層に所定の配線パターンが形成され、表層に複数の電子部品を備える多層配線板であって、電解コンデンサ4の接地側端子42と表層側接地パターン61とを接続するための接地電極部12と、接地電極部12の近傍に表層側接地パターン61の一部を切り欠いたスリット部2と、接地電極部12とスリット部2との間において表層側接地パターン61と内層に設けられる内層側接地パターン62とを接続するスルーホール3と、を備えてなる。   Such a multilayer wiring board is a multilayer wiring board in which a predetermined wiring pattern is formed on a surface layer or an inner layer, and a plurality of electronic components are provided on the surface layer, and includes a ground side terminal 42 and a surface layer side ground pattern 61 of the electrolytic capacitor 4. The ground electrode part 12 for connection, the slit part 2 in which a part of the surface layer side ground pattern 61 is cut out in the vicinity of the ground electrode part 12, and the surface layer side ground pattern between the ground electrode part 12 and the slit part 2 61 and a through hole 3 connecting the inner layer side ground pattern 62 provided in the inner layer.

また、スリット部2は、接地電極部12を不連続に囲むように設けられてなる。   The slit portion 2 is provided so as to surround the ground electrode portion 12 discontinuously.

したがって、熱容量の大きな電子部品を半田接続によって実装する場合であっても、スリット部2により接地パターンの熱伝導がある程度妨げられ、半田を溶解させるための熱量を低減することができるため、半田接続する工程において、より短時間にて半田接続可能な多層配線板となる。また、接地電極部12とスリット部2との間においてスルーホール3を設けたことによって、電解コンデンサ4からノイズが発せられてしまう場合であっても、効率よく内層側接地パターン62へ伝搬させることができ、表層側に実装される他の電子部品への影響を防止できる。   Therefore, even when an electronic component having a large heat capacity is mounted by solder connection, the heat conduction of the ground pattern is hindered to some extent by the slit portion 2, and the amount of heat for melting the solder can be reduced. In this process, the multilayer wiring board can be soldered in a shorter time. Further, by providing the through hole 3 between the ground electrode portion 12 and the slit portion 2, even when noise is emitted from the electrolytic capacitor 4, it is efficiently propagated to the inner layer side ground pattern 62. It is possible to prevent the influence on other electronic components mounted on the surface layer side.

なお、本発明の車両用表示装置を上述した実施の形態の構成にて例に挙げて説明したが、本発明はこれに限定されるものではなく、他の構成においても、本発明の要旨を逸脱しない範囲において種々の改良、並びに設計の変更が可能なことは勿論である。例えば、上述した実施の形態においては、多層配線板を貫通するスルーホール3によって、表層側接地パターン61と内層側接地パターン62を電気的に接続するものを示したが、ビルドアップビアなどのビアによって接続部を構成するものであってもよい。   The vehicle display device of the present invention has been described by way of example in the configuration of the embodiment described above, but the present invention is not limited to this, and the gist of the present invention is also achieved in other configurations. It goes without saying that various improvements and design changes can be made without departing from the scope. For example, in the above-described embodiment, the surface layer side ground pattern 61 and the inner layer side ground pattern 62 are electrically connected by the through hole 3 penetrating the multilayer wiring board. However, vias such as build-up vias are shown. The connecting portion may be configured by.
