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, 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 board material flame retardant, cem3 composite substrate is halogen-free means that does not contain halogens (fluorine bromine iodine and other elements) of the substrate, because bromine toxic when burned The gas circuit board commonly used materials, environmental protection requirements. Tg is the glass transition temperature, i.e. the melting point. Circuit board circuit board material must fire classification, at a certain temperature can not be burned circuit board material, only soften. At this temperature point is called the glass transition temperature (Tg point), this value is related to the PCB dimensional stability. Branch Snyder Department of International Ltd.

Resin adhesive sheet according to classification of different common paper-based CCI. They are: various types of phenolic resins (XPc, XxxPC, FR-1, FR-2, etc.), epoxy resin (FE-3), a polyester resin or the like. Common epoxy glass fiber cloth CCL (FR a 4, FR-5), which is a glass fiber cloth type most widely used. There are also other particularity resin (glass fiber cloth, poly amide fibers, non-woven material is increased): modified bismaleimide triazine resin (BT), polyimide resin (PI) , diphenylene ether resin (PPO), maleic anhydride imide - styrene resin (MS), polycyanate ester resin, a polyolefin resin or the like.
