The function about FR4

모모What is FR-4?At the same time, FLEX PCB It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. 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:

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.
