At present, the traditional lead frame production process is of two types, namely punching type and etching type, and punching type production is the mainstream at present. Lead frames for diodes and triodes are hundreds of varieties, and most of them are manufactured by punching. The lead frame used by the integrated circuit can be produced in quantity by the punching process of the lead frame with less than 100 pins, and can meet the use requirements of various plastic packaging forms. The etching lead frame is mainly applied to new product development and frame production with lead pitch below 0.65mm, and can produce lead frames of about 170-230 pins.
In the production and practice process, the inventor finds that the surface of the manufactured frame film is not easy to keep flat when the lead frame is manufactured by adopting the traditional punching and etching processes, and the lead frame is easy to malfunction due to the wrinkles on the surface of the frame film, so that production accidents are caused.
