Optical disc drive apparatus, flexible printed circuit board joint structure, and joint structure of flexible printed circuit boards for optical pickup

摘要

In a joint of a first flexible printed circuit board (FPC board) dividedly manufactured and fixed to an optical pickup device main body and a second FPC board dividedly manufactured and inserted into a drive side connector in an optical pickup drive apparatus, the present invention is characterized in that an end face of a base film of at least one of the FPC boards extends outward from an end face of wiring conductor. In solder bonding of a first FPC board to a second FPC board, the present invention is characterized by having a solder dam formed at a leading end of wiring of the first FPC board so as to ensure a predetermined amount of solder for re-joint when the second FPC board is removed from the first FPC board and by narrowing an end of wiring of the second FPC board.
