Important insulation material FR4 on the electrical reactor

Next, let's take a closer look at why the FR4 epoxy board is used as the insulation material.FR4 is made of epoxy resin impregnated with electrical glass cloth through high temperature and hot pressing. It has good insulation, high temperature resistance and good mechanical strength. Moreover, it is not necessary to perform the detection at regular intervals, which greatly saves manpower and material resources. FR4's high temperature resistance can reach 160 degrees. Even in the hot summer, there is no fear that it will not cause any malfunction due to excessive temperature, which will endanger people's lives and property.
