Home Industry Solutions Communication Communication module
Communication module
Modern communication equipment integrates a large number of high-performance chips, radio frequency devices and high-speed interconnect modules, which continuously generates a large amount of heat. At the same time, it needs to meet strict EMC, protection level and long-term reliability requirements. Adhesives have become a key functional material for communication equipment. Through multiple functions such as heat conduction and heat dissipation, environmental sealing, electrical insulation and EMI electromagnetic shielding, they improve system reliability, extend the service life of equipment, and meet the development needs of lightweight and integrated high-speed communication equipment.

Thermal conductive insulating coating
The power devices and metal heat dissipation structures inside communication equipment require both efficient heat dissipation and reliable electrical insulation. MCOTI's thermally conductive insulating coating is sprayed on the surface of metal substrates or heat dissipation components to provide high-voltage insulation performance while achieving rapid heat conduction and improving system thermal management efficiency.

Water-based epoxy functional coating

Metal heat dissipation substrate insulation and thermal protection

The power module is insulated from the metal structure

Suitable for aluminum alloy radiators, metal shells and other components

Meet the high reliability insulation requirements of communication equipment
