Discountable price Flex Pcb Manufacturing - 16 Layer FR4 ENIG Tg170 PCB – Huihe
Discountable price Flex Pcb Manufacturing - 16 Layer FR4 ENIG Tg170 PCB – Huihe Detail:
High Tg PCB
High Tg PCB circuit board is basically defined as PCB raw material or designed to withstand high heat resistance in high temperature PCB, high Tg is usually higher than 170°C. Therefore, the PCB with TG greater than or equal to 170°C is high Tg PCB, which can also be called glass transition temperature. High heat resistance, commonly used in lead-free process.
Advantages Of High Tg PCB Manufacturing
Own factory, factory area 12000 square meters, factory direct sales
Product 100% test (AOI scanning, 100% Flying Probe Test, FQC full inspection) to reduce the product defect rate
Through a variety of ISO certification, in line with IPC international inspection standards

FR4 TG is usually 130-140℃, and the middle TG is usually higher than 150-160℃. The humidity resistance, heat resistance, stability, chemical resistance and other properties of PCB during the manufacturing of high Tg PCB circuit board are directly dependent on the glass transition temperature.
We can help you determine if high temperature resistant printed circuit boards are needed and guide you to select the appropriate high Tg PCB circuit board.
