り窪んで凹部7を形成することになる。A circuit protection layer 3 such as a solder resist is usually provided on the conductor pattern 2 formed on the surface of the printed wiring board 1 in order to protect the conductor pattern 2. However, when connecting the connecting terminal 4 to the outside from the conductor pattern 2 of the printed wiring board l, the connecting terminal 4 is connected to the part 6.
It is necessary that the circuit protection layer 3 is not formed on the conductor pattern 2 of the printed wiring board 1, and the conductor pattern 2 is exposed to the outside. Therefore, the portion of the conductor pattern 2 exposed to the outside is recessed from the portion where the circuit protection layer 3 is provided to form a recess 7.
この凹部7に露出した導体パターン2とできるだけ広い
面積で接合するように接続端子4は金属板を折り曲げて

ことがでる。The connection terminal shown in FIG. 2 is a connection terminal that is made of a homogeneous material and has a thick convex joint portion. The connection terminal 4 and the conductor pattern 2 disposed on the surface of the printed wiring board 1 are generally joined by soldering. This bonding is performed at the connection point 6 of the conductor pattern 2 exposed in the recess 7 that is formed because the circuit protection layer 3 is not formed on the surface of the conductor bag 2.

This can be easily done by adapting the conductor pattern 2 to the conductor pattern 2.

。In particular, PGA and PLCC formed from printed wiring boards
In order to prevent the conductor patterns at the ends of the printed wiring board from becoming separated, a circuit protection layer is always provided on the peripheral edge of the printed wiring board, and the connection points between the connection terminals and the conductor patterns are protected from circuit protection. The layers form recesses. However, according to the present invention, the conductive pattern and the connecting terminal can be easily joined by using a connecting terminal having a thick convex joint at the end thereof.

すのである。In addition, the joint 5 of the connecting terminal 4 is generally a part of the circuit where electrical wiring tends to generate heat, so it is made of metal with excellent heat dissipation properties and has a protrusion that is thicker than other parts of the connecting terminal. By providing this, an excellent effect on heat dissipation is brought about.
次に、本発明の接続端子4の製造方法の一例を示す。Next, an example of a method for manufacturing the connecting terminal 4 of the present invention will be described.

り歪みなどの変形が生しるのを阻止するためである。The thick convex portion 5 formed on the connecting terminal 4 must be made of the same material as the other parts of the connecting terminal 4, because when the connecting terminal is a combination of different metals, distortion due to temperature due to the bimetallic effect can occur. This is to prevent deformation from occurring.
