What Happens When Circuit Material Heats Up? @Rogers_ACS has the answers

Heat can be damaging. Printed circuit board (PCB) materials are formulated to withstand a certain amount of heat, but when the temperatures rise beyond certain limits, circuit performance can suffer, especially at higher frequencies. Heat-tolerant PCB materials and carefully considered circuit designs can tolerate a certain amount of heat, if a circuit designer is aware of the various parameters that best describe a circuit material’s behavior when temperatures rise. Heat can come from various sources and affect circuits in different ways, especially as circuit boards are assembled with increasing density in efforts to make smaller, lighter circuit designs. Heat can be generated by a component mounted to the circuit board, or from a source external to the circuit board. Designers of high-power radar systems are familiar with the large amounts of heat generated by vacuum-tu...
