Dear Customers, Welcome to MINKINZI-China Leading Manufacturer for FPC, Rigid Flexible PCB, Rigid PCB and PCBA, Jun. 09 2020 Tuesday .
Copper thickness:1oz (35um)
Surface treatment:Immersion Gold
High-Tg (HTg) PCB is also called high-temperature PCB .Normally high Tg refers to high heat resistance in PCB raw material, the standard Tg for copper clad laminate is between 130 – 140℃, High Tg is generally greater than 170℃, and middle Tg is generally greater than 150℃. Basically the printed circuit board with Tg≥170℃, we call high Tg PCB.
As the rapid development of electric industry, especially for the computer as the representative of electronic products, developing toward the high performance, high multilayer requires PCB substrate material with higher heat resistance to ensure high reliability. On the other hand, as a result of development of SMT, CMT with high density pcb assembly technology, the PCB manufacturing with small hole size, fine lines and thin thickness are more and more inseparable from the support of high heat resistance.
Typical PCB materials for high temperature include ITEQ-IT-180A, ISOLA 370HR, Shengyi S1000-2, etc.
These PCBs are used in Multilayer boards with many layers, Industrial electronics,Automobile electronics, Fine line trace structures, High temperature electronics.
