First of all, the FFC flexible wiring process starts from the calender. The width, width and thickness of the conductor (tinned copper wire) are different according to the requirements of the order. After the conductor is made, put it into the SPOOL of the FFC equipment DIE) put the conductor into the FFC main equipment to drive through the equipment, and then carry out vision test on the semi-finished product (to detect the excellent health of the conductor). After passing through the cutting machine (the cutting length varies according to the requirements of the order), FFC flexible flat cable is finally produced through such a series of complicated procedures.
The process innovation of China's FFC flexible wiring production enterprises is driven by the demand for products from downstream manufacturers, and on the other hand, it is forced to compete with foreign manufacturers. The ways for manufacturers to carry out process innovation can also be divided into: independent research and development innovation and introduction from foreign countries.
Electroplating has been a bottleneck in the development of FFC industry, as early as 2002, South Korea and other foreign electroplating enterprises have done a lot of experiments and research and development in this regard, at present, several electroplating factories in China generally use circuit board traditional process (electroless plating) or brush conduction, or plating machine modification and other methods to try to make a breakthrough, but practice has proved that, The defective rate is still high, the quality is not stable, and the production capacity is not high.
