PRINTED CIRCUIT BOARD, FORMING METHOD THEREFOR, AND INTER-BOARD CONNECTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a printed circuit board capable of preventing a deterioration from occurring in peeling strength of a connection terminal and an insulating layer and a short circuit caused by a reservoir of excessive solder, and capable of improving connection strength between connection terminals without obstructing a reduction in a pitch between circuits. SOLUTION: The printed circuit board comprises: an insulating layer 10; a conductive circuit 11 arranged on the insulating layer 10 and equipped with connection terminals 12 at its edge; and projections 13 each provided on the connection terminal 12 in the direction in which the conductive circuit 11 is extended.
