How many types of plastic materials are used for the pin header?

Pin and female connectors are widely used in mobile phones, computers, monitors, card readers, water meters, walkie-talkies, digital cameras, computer motherboards, various mobile storage disks, security products, wireless phones, program-controlled switches, electronic toys, household appliances, etc. Plastic material is the common material of pin and nut. Plastic material can be divided into PBT, NYLON and LCP. Next, the manufacturer of the pin and nut connector will introduce the plastic material of the pin and nut. 1. PBT plastic material: low cost, high strength, friction resistance, but poor formability, serious shrinkage, due to the melting temperature, the phenomenon of plastic melting will occur during wave soldering; 2. NYLON plastic material: low cost, high tensile strength, outstanding wear resistance and self-slip, good fluidity, conducive to thin-walled molding, but serious shrinkage, easy to produce burrs, need to be strictly baked before molding, in order to prevent the production of * * * * * * *, general connectors, especially DIP, mostly use NYLON material; 3. LCP plastic material: It has small coefficient of linear expansion, low shrinkage of injection molding, outstanding strength and elastic modulus, excellent heat resistance, and high load deformation temperature, some of which can be as high as 340 degrees. LCP also has excellent chemical resistance and * * * * * * * * * *. Therefore, general connectors especially need the preferred LCP material for SMT;
