The upstream of the signal connector industry is the manufacturing of various metal materials, plastic materials and other materials; downstream is automotive, telecommunications and data communications, computer and peripheral products, industrial, military and aerospace, transportation, consumer electronics, medical and other industries.
The upstream industry of signal connector products is mainly used to manufacture various raw and auxiliary materials for connectors, including metal materials, plastic materials, electroplating materials, etc.; metal materials account for the largest proportion of cost, followed by plastic materials, and electroplating materials are small; Among them, metal materials are mainly used to make connector terminals. In order to avoid obstruction or attenuation during electronic signal transmission, (Taiwan) connector manufacturers use brass or phosphor bronze as raw materials to make copper alloy sheets. Plastics are generally used for making. The peripherals of the connector products are mostly made of LCP and PA9T. In the selection of electroplating materials, gold plating and tin plating are often used, followed by nickel plating and silver plating. According to the research data of the Taiwan Industrial Technology Research Institute, the upstream material cost accounts for about 49.6% of the total production cost of Taiwan connector manufacturers. Among them, titanium copper, LCP and other high-end raw materials are mainly imported from the United States, Japan, etc., while other copper etc. The domestic supply of raw materials is sufficient.
