If you’re looking to guard your PCBs against the high temperatures of your appliances’ process, then high Tg PCBs are necessary. Hence, there are three important ways to dissipate heat produced by electronics with High Tg PCBs. Conduction In the process of conduction, heat will cool down when it’s placed next to its source. This is done by using a sink for the heat that has been produced- similar to electricity flowing through an electric system. Radiation With a powerful enough radiation, the electromagnetic waves will create an exit path to leave. Convection The process of convection is a great example. It’s the movement of heat to water or air, enabling it to flow out from an area. For instance, you can see this in action when using pumps and fans that push hot air over surfaces while also drawing away some of its heat with the device.
