Structure for mounting connector on board |
摘要 |
A connector has terminals, each having a tip end portion. A wiring board has through holes. A land is provided on the wiring board about each through hole. When the connector is mounted on the wiring board, each terminal is connected to one of the lands with a part of the tip end portion being located in the corresponding through hole. The ratio of the cross-sectional area of each tip end portion to the cross-sectional area of each through hole is at least 0.11 and no more than 0.89. This improves the reliability of the joint portions between the terminals and the wiring board.
