Description

technical field [0001] The invention relates to the technical field of double-sided adhesive tape, and specifically designs a heat-dissipating double-sided adhesive tape. Background technique [0002] Heat dissipation double-sided adhesive is a kind of high-performance acrylic pressure-sensitive adhesive filled with high thermal conductivity ceramic particles coated on both sides of glass fiber cloth or without substrate. The heat dissipation double-sided tape provides an efficient heat conduction channel between the electronic device and the heat sink. It has good viscosity and can fix the heating element and the heat dissipation body together as a whole to enhance the heat dissipation effect and make the electronic device and heat dissipation There is no longer any need for mechanical fixation and liquid adhesive curing fixation between devices. Heat-dissipating double-sided adhesive is currently the most widely used intermediate heat-conducting adhesive on electronic equ...
