The main material of PCB is epoxy resin. The Tg value of the resin represents the temperature at which it changes from the glass state to the rubber state. That is, the resin material of the PCB is in a hard glass state below the TG temperature. If the temperature reaches above the TG temperature of the board, the epoxy resin will become highly elastic. The state becomes an elastic rubber state. In this case, the electronic product obviously loses its stability and reliability. Therefore, choosi
