Description

Technical Field

[0002] Thermal conductive gaskets are widely used in industries such as electronics, electrical, and communication, especially in heat conduction and sealing of devices such as chips, integrated circuits, and power modules. Due to their excellent thermal conductivity, thermal conductive gaskets can effectively dissipate heat and ensure the stable operation of devices. In the electrical industry, thermal conductive gaskets are used for sealing and heat conduction of high-voltage electrical appliances such as high-voltage switches, which can effectively ensure the stable operation of electrical equipment. In the communication industry, thermal conductive gaskets are used for sealing and heat dissipation of base station equipment, antenna equipment, etc., which can significantly improve the transmission efficiency and stability of communication equipment.

[0003] A thermal conductive gasket with a pulling mark is a product with a specific mark added to the thermal conductive gasket.
