SOLDERING JOINT STRUCTRUE OF PRINTED CIRCUIT BOARD WITH EXCELLENT SOLDER DISCHARGING PROPERTY

摘要

PURPOSE: A soldering joint structure of a printed circuit board with high solder discharging properties is provided to improve the utilization of a space by arranging an external connection terminal in zigzags. CONSTITUTION: A hard printed circuit board (120) includes a first external connection terminal. The first external connection terminal is arranged on one end of a hard printed circuit board body. A flexible printed circuit board (140) includes a second external connection terminal (145) and a solder discharge hole. The solder discharge hole passes through the second external connection terminal. The first external connection terminal is directly bonded to the second external connection terminal with solder to be electrically connected.
