. They are up to 10 times as thermally conductive as PCBs made with epoxy glass and incredibly thinner. They don’t require a lot of copper, so you can save money on costs while boosting their effectiveness

) is greater than 170°C. The glass transition temperature is one of the most important properties of any epoxy, representing the temperature which the polymer transition from a hard material to a soft one

. These include FR4, copper, solder mask, and silkscreen. FR4 FR stands for “flame retardant.” FR4 is a glass-reinforced epoxy resin laminate
