Problems solved by technology

[0002] The existing FPC forming method is generally to punch and shape the full-page FPC that has been pasted with reinforcement. The force applied to the junction of the FPC reinforced area and the non-reinforced area is uneven, which causes the junction of the FPC and the reinforcement to be easily torn, resulting in poor FPC

Abstract

The invention provides a flexible circuit board moulding method. The flexible circuit board moulding method comprises the following steps: providing an FPC substrate, wherein the FPC substrate comprises a plurality of FPC units, each FPC unit comprises an overall outer frame line, each FPC unit comprises a reinforcing zone and a non-reinforcing zone, and the overall outer frame line comprises a connecting outer frame line arranged along an outline of a junction of the reinforcing zone and the non-reinforcing zone, a reinforcing outer frame line arranged around only the reinforcing zone and connected with the connecting outer frame line, and a non-reinforcing outer frame line arranged around only the non-reinforcing zone and connected with the connecting outer frame line; punching the connecting outer frame line; arranging a reinforcing layer on the reinforcing zones of the plurality of FPC units; punching the reinforcing outer frame line and the non-reinforcing outer frame line. The invention further provides a mould for the flexible circuit board moulding method. Through the flexible circuit board moulding method and the mould, a defective FPC caused by easy tearing of the junctions of the reinforcing zones and the non-reinforcing zones of the FPC units can be avoided.

Description

technical field [0001] The invention relates to a flexible printed circuit board (Flexible Printed Circuit Board, FPC), in particular to a molding method and a mold for a flexible printed circuit board. Background technique [0002] The existing FPC forming method is generally to punch and shape the full-page FPC that has been pasted with reinforcement. The applied force at the junction of the FPC reinforced area and the non-reinforced area is not uniform, so that the junction of the FPC and the reinforcement is easily torn, resulting in a defective FPC. Contents of the invention [0003] Based on this, a molding method and a mold of a flexible circuit board are provided so that the FPC reinforced joint is not easily torn. [0004] The invention provides a molding method of FPC, comprising: [0005] S1, providing an FPC substrate, the FPC substrate includes a plurality of FPC units, each FPC unit is provided with an overall outline frame line, and each FPC unit is provid...
