The role of thermal gel and the heat dissipation application of PCB board

Electronic equipment will definitely generate heat when it is working. Since it is impossible to avoid heat generation, then prepare for heat dissipation. The PCB board is the carrier of electronic components and the carrier for the electrical interconnection of electronic components, so do a good job of PCB board Heat dissipation preparation can largely guarantee the operation of electronic equipment.

As the main body of electronic equipment heating, electronic components will generate heat when they are powered on. Air is a poor conductor of heat. If the heat is dissipated outward by the heat source, the heat dissipation effect will be poor. The electrical performance of the PCB board The processing performance is very good, but the heat dissipation is poor, so the heat dissipation treatment method is to install a heat dissipation device on the heat source, and conduct the excess heat of the heat source to the heat dissipation device to reduce the temperature.

Thermally gel is one of many thermally conductive materials. It is specially used to deal with the heat conduction problem of equipment. By filling the gap between the heat dissipation device and the heat source of the equipment, the air in the gap is eliminated and the heat source and the heat dissipation device are in close contact, thereby reducing the gap between the two. Contact thermal resistance, improve heat conduction speed, so as to achieve heat dissipation effect.

Thermally gel has a great advantage in heat dissipation of PCB boards. Unlike thermal pads, it needs to be cut according to the area to be attached to the plane. It is inconvenient to mount or store, but thermally conductive gel can be ordered according to the area. Glue, and thermal gel with dispensing machine can be used for assembly line dispensing work, which is very convenient and efficient.
