化にも限界があった。The size of a land for fixing a chip resistor or an IC to an electric wiring board such as a printed board is usually
Since it is designed to be larger than the chip resistor and the width of the IC pin, there is a limit in narrowing the land pitch and narrowing the IC pin pitch.

Then, as shown in the perspective view of FIG. 11 and the cross-sectional view of FIG. 12, the plurality of lead terminals 61 projecting from the component package 6 to the side face have an angle 90 so that the wide surface is perpendicular to the land 76. Twist only to form and land 76

め、ハンド接着時にハンダ8によるブリッジが発生する
恐れがあった。A first problem with these conventional surface mount electronic components is that if the width of the land 76 is not made wider than the width of the lead terminal 61 as shown in FIG. As shown in FIG. 13, the contact area between the land 76 and the lead terminal 61 via the solder 8 becomes extremely small, so that the contact strength is weakened. In order to increase the contact strength, as shown in FIG. Must be made wider than the width of the lead terminal 61. For this reason, there is a possibility that a bridge may be generated by the solder 8 during hand bonding.
【0006】その理由は、リード端子61の底面がラン
ド76に対して、平行であったことによる。The reason is that the bottom surface of the lead terminal 61 is parallel to the land 76.
