The substrate of High Tg circuit board will change from “glass state” to “rubber state” when the temperature rises to a certain area, and this temperature is called the glass transition temperature (Tg) of the board. In other words, Tg is the maximum temperature (℃) at which the substrate remains rigid. That is to say, ordinary PCB substrate materials at high temperature not only produce softening, deformation, melting and other phenomena, but also performance in the mechanical, electrical characteristics of a sharp decline (I don’t think we want to see their products appear this situation).
Generally speaking, the board of Tg is more than 130 degrees, high Tg is more than 170 degrees, and medium Tg is more than 150 degrees.
Usually Tg≥170℃ PCB, called high Tg PCB.
When the Tg of the substrate increases, the circuit board’s heat resistance, moisture resistance, chemical resistance, stability resistance and ot
