本発明はプリント回路基板に係り、特に方向性のある部
品の組込み方向を示すマーク形成ｉこ関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to printed circuit boards, and particularly to the formation of marks indicating the installation direction of directional components.

すなどのことが行われている。なお、上記手段を施した
ものとして、例えば雑誌「電子材料Ｊ １９８５年１０
月号第１３頁に記載されている。FIG. 2 shows a conventional printed circuit board. That is, on the printed circuit board 1, a circular through hole land 3 is formed around the through hole 2. In addition, as a mark to indicate the installation direction of components with a direction, such as dual inline parts (f) ICs, a silk-print display 4 may be provided or a pattern may be left near the through-hole land 3. It is being said. In addition, for example, the magazine "Electronic Materials J October 1985"
It is listed on page 13 of the monthly issue.
部品の組込み方向を示すマークとして、前者のシルク印
刷表示による手段は、このシルク印刷のための工程が増
加し、コスト高になる。また後者のスルホールランドの
近くにパターンを残す手段は、回路パターンの配線の邪
魔になり、パターン設計上の煩わしさがあった。The former method of using silk-screen printing as a mark to indicate the direction in which parts are to be assembled requires an additional process for silk-screen printing, resulting in high costs. In addition, the latter method of leaving a pattern near the through-hole land interferes with the wiring of the circuit pattern, causing trouble in pattern design.
本発明の目的は、シルク印刷が不要で安価にできると共
に、パターン設計も容易にできるプリント回路基板を提
供することにある。An object of the present invention is to provide a printed circuit board that does not require silk printing, can be made inexpensive, and can be easily patterned.
上記目的は、一つあるいは一方のスルホールランド形状
を他のスルホールランド形状と異なる形状に形成するこ
とにより達成される。The above object is achieved by forming one or one of the through-hole lands in a different shape from the other through-hole lands.
例えば１４ピンＤＩＰ、ＩＣの場合、１ビンのスルホー
ルランド形状を他の１３ピンのスルホールランド形状と
異なったものにすることにより、前記１ピンのスルホー
ルランドの位置で方向性が判別でき、ＤＩＰＩＩＣの組
込み方向のマークとしての機能をもつ。For example, in the case of a 14-pin DIP or IC, by making the through-hole land shape of 1 pin different from the through-hole land shape of the other 13 pins, the directionality can be determined by the position of the through-hole land of the 1 pin, and the DIPI IC It functions as a mark for the installation direction.

円形状に形成されている。An embodiment of the present invention will be described below with reference to FIG. A printed circuit board 1 is provided with a large number of through holes 2 corresponding to, for example, one IC. Further, one through hole land 5 is formed in a square shape, and the other through hole land 6 is formed in a circular shape.
従って、前記角形状のスルポールランド５によってＩＣ
などの部品の組込み方向が判別でき、部品の組込みが容
易にできる。Therefore, the IC
It is possible to determine the installation direction of parts, such as, and facilitate the installation of parts.
このように、スルポールランド５．６の形状を変えるの

シルク印刷による表示が不要となり、安価にできる。ま
たスルホールランドの近くにパターンを残す必要もない
ので、パターン設計が容易である。In this way, the function of identifying the component installation direction can be obtained by simply changing the shape of the Surpol land 5.6, and the conventional display using silk printing is not required, making it possible to reduce the cost. Further, since there is no need to leave a pattern near the through-hole land, pattern design is easy.
なお、上記実施例においては、一つのスルホールランド
５の形状を角形に形成した場合について説明したが、２
列１組のスルホールランド群の内、左側を角形にし、右
側を円形に形成してもよい。In the above embodiment, the case where one through hole land 5 is formed into a rectangular shape has been described, but two
Of the through-hole land groups in one row, the left side may be square and the right side may be circular.
またスルポールランド５．６の形状は角形、円形に限ら
なく、両者が区別できる形状であれば他の形状の組合せ
でもよい。Further, the shape of the Surpol land 5.6 is not limited to square or circular, but may be a combination of other shapes as long as the two can be distinguished.
本発明によれば、スルホールランド形状で部品組込みの
方向性が判別できるので、シルク印刷ｌこよる表示が不
要で安価にできると共ζこ、パターン設計が容易である
。According to the present invention, since the direction of component assembly can be determined based on the through-hole land shape, it is not necessary to use silk printing for display, which makes pattern design easier.
