Abstract:
1. A process for connecting a first printed circuit board to a second printed circuit board with a conductive pattern on the first printed circuit board aligned and coplanar with a conductive pattern on the second printed circuit board, the conductive patterns on the first and second circuit boards connected by soldering, wherein: the first printed circuit board has laterally spaced, opposing side edges and a connecting edge extending between the opposing side edges, an elongate hole is formed in the vicinity of and along an edge portion in a connecting part of the second printed circuit board, and rectangular holes wider than and communicating with said elongate hole are formed at both longitudinal ends of said elongate hole, and cutouts for controlling insertion depth are provided at both ends of the connecting edge of the first printed circuit board, and a leading edge of the first printed circuit board, which extends between and intersects said cutouts and has a length less than the length of the connecting edge, is bent downward to form a bent portion, and said bent portion is inserted into said elongate hole and said rectangular holes of the second printed circuit board to position the first printed circuit board with the conductive patterns on the first and second printed circuit boards, which are aligned and coplanar with each other, connected by soldering.
