Problems solved by technology

The existing solution to equipment heating and electromagnetic shielding is to use electromagnetic shielding components and heat conduction and heat dissipation components in combination, which not only increases the overall manufacturing cost of the equipment, but also uses multiple components in combination, occupying the assembly space of the equipment, and cannot further reduce the equipment. Thickness, and the existing heat conduction and electromagnetic shielding materials are limited by the material, the efficiency is extremely low, and the manufacturing cost is high
