STRUCTURE AND METHOD FOR CONNECTING WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a structure and a method for connecting a wiring board that can improve the connection strength between a connected object and the wiring board.

SOLUTION: In a structure for connecting a wiring board, an input contact of a piezoelectric actuator and a board-side contact of a COF 50 (Chip On Film) of a printer are electrically connected by a conductive part made of conductive resin containing metallic material and thermosetting resin. And the piezoelectric actuator and the COF are mechanically connected to each other via a reinforcement part 62 in addition to the conductive part. The reinforcement part 62 is located at a position different from the conductive part in the COF 50 and arranged at a position straddling a surface of a solder resist 54 and a surface of a flexible substrate 52.
