...It is necessary to completely remove each solder in step 2, and in this case, the metal foil of printed circuit board 3 may peel off from the printed circuit board, and the printed circuit board may also have to be replaced. The drawback was that it required a lot of effort and time. The present invention seeks to provide a mounting method that can completely overcome these drawbacks.
即ち、第３図ないし第５図に示す如く、本発明ではＩＣ

す如く弾性変形させたままで、半田付７を施す。That is, as shown in FIGS. 3 to 5, in the present invention, the IC
The lead terminal 2 of I is formed of an elastic metal such as phosphor bronze, this lead terminal 2 is bent in advance into an N shape, etc., and the leads are connected from the first bent part P of the approximately V shape and the first bent part P. A second bent portion Q is formed at a position separated by a predetermined distance d in the insertion direction of the terminal 2. The first bent portion P of the lead terminal 2 formed in this way is loosened against the top surface of the printed circuit board 3, and the lead terminal 2
By elastically deforming the second bent part Q in the insertion direction, which is separated by a distance d in the insertion direction of the lead terminal 2, the lead terminal 2 is given an elastic return force in the opposite direction to the insertion direction, and the terminal is automatically removed from the printed circuit board by the elastic force simply by melting the solder at the tip of the lead terminal. More specifically, as shown in FIG. 3, the wire terminal 2, which is bent in an N-shape in advance, is inserted into the terminal hole 4 of the printed circuit board 3, as shown in FIG.
, and press in the direction of arrow A with a U-shaped lead terminal pressing tool 6 as shown in FIG. 6, and solder 7 while keeping the lead terminal 2 elastically deformed as shown in FIG. .
さて、ＩＣが不良のため、部品交換を行なう際、半田付

ト基板３への係止片８，８を設け、それをプリント基板
３に係止しておけば、半田付け作業を更に簡単に行なう
ことができる。Now, since the IC is defective, when replacing the parts, the solder joint 7 is melted, and the terminal 2 returns elastically using point P as a fulcrum, as shown in FIG. 4, and completely separates from the metal foil portion 5.
When soldering the lead terminals 2 of the ICI, as shown in FIG. If it is locked, the soldering work can be performed more easily.
従来の非弾性のりード端子を有するＩＣは取外しが困難
であり、金属箔パターン面の半田をとりのぞくために、
パターンの加熱時間が長く、パターン面の浮きやプリン
ト基板上の他部品が熱で破損する恐れがあった。上述の
如く、本発明の取付方法はリード端子に弾性を持たせ、
半田を溶かせると、端子の弾性復帰力により端子がプリ
ント基板の端子孔から抜け出るように、リード端子を弾
性変形させたまま半田付けしている。Conventional ICs with inelastic lead terminals are difficult to remove, and in order to remove the solder from the metal foil pattern surface,
The heating time for the pattern was long, and there was a risk that the pattern surface would lift or other components on the printed circuit board would be damaged by the heat. As mentioned above, the mounting method of the present invention provides elasticity to the lead terminal,
The lead terminals are soldered while being elastically deformed so that when the solder is melted, the elastic return force of the terminals causes the terminals to come out of the terminal holes of the printed circuit board.
従って、プリント基板の半田を溶かすだけで、電気部品
がプリント基板から取り外せるので、電気部品を長時間
加熱する必要がなく、そのため電気部品の熱破壊を防止
でき、而も部品交換のサービス性および生産性が非常に
よい。Therefore, the electrical components can be removed from the printed circuit board by simply melting the solder on the printed circuit board, so there is no need to heat the electrical components for a long time, which prevents thermal damage to the electrical components, and improves serviceability and productivity for parts replacement. Very good quality.
