Description

Technical Field

[0001] This utility model belongs to the field of FPC processing technology, specifically relating to an FPC stamping die structure with trimming function. Background Technology

[0002] FPC stamping dies are tools used to produce flexible printed circuit board (FPC) connectors and other electronic components. FPC is a flexible material commonly used in electronic products such as mobile phones and tablets. Stamping dies are used to precisely process FPC by placing the FPC material in the die and using stamping processes to cut and shape it. These dies generally consist of an upper die and a lower die, and the die surface has a variety of precise shapes and holes, which can realize the processing of FPC products of different specifications and shapes. The design of FPC stamping dies requires high precision and high stability because FPC material is thin and easily damaged. The die needs to ensure that the material is not damaged during processing. With the increasing miniaturization and high precision requirements of electronic products,

[0003] Traditional FPC stamping dies often result in burrs on the finished FPC cables after stamping and cutting flexible printed circuit board (FPC) materials. Burrs not only affect the appearance quality of the FPC cables but can also lead to short circuits or poor connections, thus impacting the performance and reliability of electronic products. Especially in high-precision applications, burrs significantly reduce product yield and increase subsequent cleaning and processing costs. Furthermore, burrs can interfere with other components during assembly, increasing assembly difficulty and even causing defects. With the miniaturization and increasing complexity of electronic products, the challenge posed by burrs to FPC stamping processes is becoming increasingly significant. Existing traditional die designs struggle to meet the requirements of high-precision, low-defect production. This problem not only affects production efficiency but may also lead to additional investment in quality control and production processes. Therefore, those skilled in the art provide an FPC stamping die structure with trimming capabilities to address the problems mentioned in the background. Utility Model Content
