DOUBLE FACED PRINTED CIRCUIT BOARD INTERCONNECTION

摘要

DOUBLE-FACED PRINTED CIRCUIT BOARD INTERCONNECTION A double-faced printed circuit board comprises an insulative base board, a first conductive circuit interconnection pattern formed on one face of the base board, a second conductive circuit interconnection pattern formed on the other face of the base board, a first through-hole extending from the first circuit interconnection pattern through the base board and formed at such a position that the first through-hole is not aligned with the second circuit interconnection pattern, a second throughhole extending from the second circuit interconnection pattern through the base board and formed at such a position that the second through-hole is not aligned with the first circuit interconnection pattern, and a conductive connecting member inserted into the first and second through-holes while bridging them. The first circuit interconnection pat-tern is soldered to the connecting member while the second circuit interconnection pattern is also soldered to the connecting member to establish electrical connection between the first and second patterns.
