TG150FR4 is a type of glass fiber epoxy resin copper-clad board, which belongs to the FR4 board category. FR4 board is a substrate in circuit boards, mainly composed of glass fiber cloth and epoxy resin.
TG150 indicates that the glass transition temperature (Tg) of the material is 150 ℃. The glass transition temperature is the temperature at which a material transitions from a glassy state to an rubbery state, and it is also the highest temperature at which a material maintains its rigidity. Therefore, TG150FR4 has high heat resistance.
In addition to heat resistance, TG150FR4 also has good moisture resistance, chemical resistance, and stability resistance.
TG150FR4 is mainly used for manufacturing printed circuit boards (PCBs), especially in applications that require high heat resistance, such as lead-free processes.
