Method of fabricating rigid-flexible printed circuit board
摘要:
The present invention is related to a method of fabricating a rigid-flexible printed circuit board. Specifically, this invention relates to a method of fabricating a rigid-flexible printed circuit board, in which an internal circuit pattern exposed for use in an external pad and a mounting pad is protected from external environments using a resist cover by window etching the base copper foil of a flexible region upon formation of an external circuit pattern as opposed to using a resist cover. Thus the number of fabrication processes and the fabrication costs are decreased and the increase in defect rates due to contamination is prevented, resulting in maximized reliability.
