Mechatronic three-dimensional printed circuit board (PCB) has contact surfaces or pads that are evenly spaced in opposite edge portions of insertion slot, and made of copper alloy and coated with tin by solder connection

摘要

The PCB (1) has an insertion circuit board (3) that is partially assembled on a base board (2) which is formed with an insertion slot according to layout of conductor tracks. The contact surfaces (4) or pads (10) are evenly spaced in opposite edge portions (6) of the insertion slot, and made of copper alloy and coated with tin by solder connection. The insertion circuit board is arranged with an insertion tongue in the edge portions.
