FPC flexible circuit board is made of polyimide or polyester film, which has high reliability and excellent flexible printed circuit board. Referred to as soft board or FPC, it has the characteristics of high density, light weight and thin thickness. Flexible circuit board is a kind of flexible printed circuit board with high reliability and excellent flexibility, which is made of polyimide or polyester film. Referred to as soft board or FPC, it has the characteristics of high density, light weight and thin thickness. It is mainly used in mobile phones, notebook computers, PDA, digital cameras, LCM and many other products.

There must be a complete and reasonable production process to make a good FPC board by pre-processing before folding. Every procedure must be strictly implemented from pre-processing to final shipment. In the production process, in order to prevent too much open and short circuit and cause too low yield or reduce drilling, calendering, cutting and other process problems caused by the FPC board scrap, replenishment problems, and evaluate how to select materials to achieve the best effect of customer use. Prenatal pretreatment is particularly important.

There are three aspects to be dealt with in prenatal pretreatment, which are all completed by engineers. The first is FPC board engineering evaluation, which mainly evaluates whether the customer's FPC board can be produced, whether the company's production capacity can meet the customer's plate making requirements and unit cost; If the project evaluation is passed, the next step is to prepare materials immediately to meet the supply of raw materials for each production link. Finally, the engineer processes the customer's CAD structure drawing, Gerber line data and other engineering documents to suit the production environment and production specifications of the production equipment, and then hand over the production drawings and mi (engineering process card) and other data to the production department, document control, procurement, etc Department, enter into the routine production process.
