The function about FR4
02/19/2025모모What is FR-4?In the industry, PCB manufacturing in China Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. https://www.wellcircuits.com/

모모FR-4 is a grade for flame-retardant fiberglass reinforced epoxy material. Therefore, FR-4 PCBs offer a higher level of heat resistance compared to standard PCBs. The FR-4 board is classified into three categories based on the number of copper trace layers:
모모
모모Single-layer PCB
모모
모모Two-layer PCB
모모
모모Multilayer PCB

모모High TG PCB Specifications
모모
모모The 몷Tg몸 refers to the glass transition temperature of the PCB. It indicates the temperature at which the material begins to transition from a solid state to a liquid state (learn more about Tg). If the operating temperature exceeds the specified Tg value, the circuit board can lose its structural integrity, which may negatively affect its functionality.
모모
모모Standard PCBs typically have a Tg value of 130뫢C C 140뫢C, while high-Tg PCBs range from 170뫢C to 180뫢C.
