Pre-treatment of FPC flexible circuit boards requires handling three aspects, whichAll three aspects are completed by engineers. First is the FPC board engineering evaluation, which mainly assesses whether the customer's FPC board can be manufactured, whether the company's production capacity can meet the customer's board-making requirements, and the unit cost. If the engineering evaluation is approved, the next step is to immediately prepare materials to meet the supply of raw materials for each production stage. Engineers handle the customer's engineering files, such as CAD structural drawings and Gerber circuit data, to make them suitable for the production environment and specifications of the equipment. Then, the production drawings and MI (engineering process cards) and other materials are distributed to the production department, document control, procurement, and other departments, entering the regular production process.
