[0002] Flexible circuit board is a type of circuit board. Its advantages are high assembly density, good bendability, high softness, light weight and easy installation. The flexible circuit board stamping die is a device used to stamp and shape the external shape of the flexible circuit board during the production and processing process.

[0003] Since the stamping die for flexible circuit boards is often difficult to demould and cut during actual operation, and the bottom of the flexible circuit board is easily adhered to the inner wall of the lower stamping die during the stamping operation, and it is easy to break when directly torn off, it can no longer meet people's needs. Therefore, we propose a new type of stamping die for flexible circuit boards that is easy to demould to solve the above-mentioned defects. Utility Model Content
