Reinforcing plate integrated flexible printed circuit board, and the reinforcing plate manufacturing method of an integrated flexible printed circuit board

摘要

Object of the present invention, the reinforcing plate integrated flexible printed circuit and the reinforcing plate integrated flexible printed circuit board are characterized in that they be attached to a reinforcing plate in the photosensitive resin composition on, defects such as swelling does not occur in the reflow mounting It is to provide a manufacturing method of a substrate. Reinforcing plate one made up in the order of (C) a photosensitive resin composition cured film (5), (4), (D) a flexible printed circuit board (1) (A) a reinforcing plate (6), (B) cement By adopting the configuration of the integrated flexible printed circuit board, it is possible to solve the above problems.
