Connecting structure of printed circuit boards

摘要

Lands formed on a flexible printed circuit board are electrically connected with lands formed on a rigid printed circuit board through solder. At this point, solder resist is formed between neighboring two lands on the rigid printed circuit board, and is terminated with an end portion that is interposed between the rigid printed circuit board and the flexible printed circuit board. Accordingly, even when surplus solder is extruded onto the rigid printed circuit board, the solder resist can prevent solder bridges from being formed between the lands.
