とするものである。[Detailed description of the invention] The invention relates to a printed wiring board in which leadless components and leaded components are attached to a printed circuit board, and the printed circuit board warps and cracks occur in the soldered parts of the dressed components. The object of the present invention is to provide a printed wiring board on which components can be mounted at a relatively high density without causing problems.
１０ｃｒｎＸ１０ｃｍ以上の面積を持つプリント基板で
は、半田デイツプ槽で半田付けをすると、その時の熱に
よってプリント基板が少し反ることがある。When a printed circuit board with an area of 10 crn x 10 cm or more is soldered in a solder dip bath, the printed circuit board may warp slightly due to the heat generated.
このため、プリント基板の裏面の銅箔に剛性の大きい抵
抗等のリードレス部品が半田付けされている場合には、
上述の反りによってその半田付部分にひびが入ることが
ある。For this reason, if leadless components such as highly rigid resistors are soldered to the copper foil on the back of the printed circuit board,
The above-mentioned warping may cause cracks in the soldered portion.
そこで、本考案は、半田デイツプ槽による半田付けの際

考案の一実施例について図面を参照して説明する。Therefore, the present invention is designed to prevent cracks from occurring in the soldered parts of dress parts even if the printed circuit board is warped during soldering using a solder dip tank, and also to allow parts, including parts with leads, to be packed in high density. The present invention is intended to provide a printed wiring board that can be mounted, and one embodiment of the present invention will be described below with reference to the drawings.
図に示すように、このプリント配線基板では、プリント
基板１に半田デイツプ槽で半田付けをすることによって

抵抗等のリードレス部品２が半田付けされる。As shown in the figure, in this printed wiring board, a leadless component 2 such as a resistor with high rigidity is soldered to the copper foil on the back side of the printed circuit board 1, which is produced by soldering to the printed circuit board 1 in a solder dip tank. be done.
３は半田である。一方、図に示すように、上記リードレ

表面に抵抗等のリード付部品４が配置され、このリード
付部品４のリード線４ａ、４ｂがプリント基板１の透孔
に挿入されて裏面で銅箔と半田付けされている。3 is solder. On the other hand, as shown in the figure, the leadless components 2 are arranged in the orthogonal direction, and a leaded component 4 such as a resistor is arranged on the surface of the printed circuit board 1, and lead wires 4a, 4b of the leaded component 4 are arranged. is inserted into the through hole of the printed circuit board 1 and soldered to the copper foil on the back side.
５ａ、５ｂは半田である。5a and 5b are solder.
以上のような構成により、リードレス部品２の配列方向

ドレス部品２の半田付は部分にプリント基板１の反りに
よる力が加わることがなくなり、この半田付部分にひび
が入ることがない。With the above configuration, the arrangement direction of the leadless components 2 is perpendicular to the warpage curve of the printed circuit board 1, so that no force is applied to the soldering portion of the leadless components 2 due to the warpage of the printed circuit board 1. , this soldered part will not crack.
また、リード付部品４をリードレス部品２と直交する方
向に配列したのできリードレス部品２との間で相互に邪
魔になることがなく、部品を高密度に取付けることがで
きる。Furthermore, since the leaded components 4 are arranged in a direction perpendicular to the leadless components 2, they do not get in the way of each other and the components can be mounted at high density.
以上のように本考案によれば、リードレス部品をプリン
