The invention discloses a battery FPC manufacturing method and a battery FPC, which belong to the technical field of flexible circuit board production. The battery FPC manufacturing method comprises the steps of: fixedly arranging a plurality of single-piece FPCs on a substrate splicing plate in sequence, wherein each of the single-piece FPCs is provided with a steel sheet bonding region; performing pre-processing, so that the plurality of single-piece FPCs are in a state to be attached with steel sheets; attaching repaste steel sheets onto the substrate splicing plate; subjecting the repastesteel sheets and the substrate splicing plate to pressing-fit processing; attaching a cover film onto the substrate splicing plate continuously, wherein the cover film covers the regions where all thesteel sheets are arranged; subjecting the cover film and the substrate splicing plate to pressing-fit processing; and punching the substrate splicing plate. The battery FPC manufactured by adopting the battery FPC manufacturing method has the advantages of high safety, simple structure, low cost and convenient mass production.
Description
technical field [0001] The invention belongs to the technical field of flexible circuit board production, and in particular relates to a method for manufacturing a mobile phone battery FPC reinforced with an insulating steel sheet and the battery FPC. Background technique [0002] Flexible Printed Circuit (FPC for short) is a printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the substrate. With the popularization of smart mobile terminals, mobile phones It has become an indispensable part of our life. The mobile phone battery is an important part of the mobile phone. The mobile phone battery is an energy storage tool that provides power for the mobile phone. It consists of three parts: the battery cell, the protection circuit and the shell. Batteries and Ni-MH batteries, because mobile phone batteries are flammable and explosive items, if there is no protection circuit inside the battery, it will be easily deformed, ...
