That is, Tg is the temperature of the substrate to maintain the highest rigidity (℃). That common PCB substrate material at high temperatures, the continuous generation of softening, deformation, melting and other phenomena, but also reflected in a sharp decline in mechanical, electrical characteristics of Shenzhen pcb allegro proofing, so that the child will affect the life of the product prototype pcb in Shenzhen proofing, or more generally sheet Tg 130 ℃, high Tg generally greater than 170 ℃, moderate Tg greater than about 150 ℃; usually a Tg ≥ 170 ℃ PCB board pcb, printed circuit board called the high Tg; Tg of the substrate is increased, PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics will be improved and improved. TG higher the value, the better the sheet temperature resistance pcb factory in Shenzhen, especially in the lead-free manufacturing process, high Tg applications more; higher Tg refers to a high heat resistance. With the rapid development of the electronics industry, especially in the computer as the representative of electronic products, toward the high function, high multi-layered development requires as a prerequisite for higher heat resistance PCB circuit board substrate material. The emergence and development of SMT, CMT, represented by high-density mounting technology, the PCB in a small aperture, fine lines, thin areas, increasingly inseparable from the high heat resistance of the substrate support
