If it cannot be dissipated in time, the performance of various chips and components on the circuit board will be reduced or even burned. In order to minimize the interference of the external environment on the circuit board, the electrical equipment is generally installed inside the housing of the electrical equipment, surrounded by many other components, so the heat generated on the circuit board is difficult to dissipate heat through heat exchange with the surrounding air , so it is necessary to place a heat sink on it.
