Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high Shenzhen circuit board quality, quality assurance, the melting point of the printed circuit board materials, the price is reasonable. High Tg refers high heat resistance. With the rapid development of the electronics industry, especially in the computer and electronic products, represented towards high performance, high multi-layered development requires a higher heat resistance as an important guarantee of the PCB substrate material. In SMT, CMT, represented by high-density mounting technology emergence and development of circuit board materials commonly used to make PCB in a small aperture, fine lines, thin side, more and more inseparable from the high heat resistance of the substrate support. Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer circuit board professional supplier of halogen-free materials for clients provide high-precision, high-quality Shenzhen circuit board circuit board material quality assurance, reasonable prices. Classification board classification c retardant characteristics can be divided into 94V-0 / V-1 / V-2, 94-HB four prepreg: 1080 = 0.0712mm, 2116 = 0.1143mm, 7628 = 0.1778mm.FR4 CEM -3 are represented plate, fr4 glass fiber, cem3 composite substrate is halogen-free means that does not contain halogens (fluorine bromine iodine and other elements) of the substrate, because bromine in the combustion produces toxic gases, environmental requirements. Tg is the glass transition temperature, i.e. the melting point. Circuit board must fire, at a certain temperature does not burn, only soften. At this temperature point is called the glass transition temperature (Tg point), this value is related to the PCB dimensional stability. Circuit board material, board material flame resistance, Newell Year (certified merchants) are provided by Shenzhen-Electronic Technology Co., Ltd. Department.
