Manufacturing method of flexible printed circuit board for manufacturing bank card patterns

The invention discloses a manufacturing method of a flexible printed circuit board for manufacturing bank card patterns. As for the method, firstly the flexible printed circuit board is manufactured with a special printed circuit board processing technology for required patterns, and then the patterns are formed on a bank card base material which is formed by pressing, which have obvious concave-convex feeling, and meet the demands of customers on high-grade bank cards. The method comprises the main steps of rough shape cutting, electrocoppering, protective dry film adhering, etching and stripping, gum adhering, rapid pressing, dry film adhering, exposure imaging, etching and stripping, nickel depositing, molding and the like; and after the manufacture is accomplished, exposed gum is served as pre-binding material used for being pressed to a bank card; and when the gum is pressed to the bank card base material, only the patterns are golden, and the other parts are still transparent.
