Problems solved by technology

[0003] The conventional PCB solution is to use heat-conducting plates and dense heat dissipation holes for high-power device areas, but the heat conduction effect of heat-conducting plates and dense heat-dissipating holes is not good, and the dielectric loss coefficient of the plates is large, resulting in poor heat dissipation in the area of ​​micro high-power devices. , Signal transmission loss and distortion are serious, which affects the signal quality of communication products
[0004] Another solution to heat-dissipating PCBs is to use laminated embedding or embedding heat-conducting materials as heat-conducting channels in the high-power device area.

Description

technical field [0001] The invention relates to the field of heat dissipation of electronic equipment, in particular to an electronic equipment with an asymmetric heat dissipation structure. Background technique [0002] At present, there is a design for high-end wireless communication in the printed circuit board (PCB) industry: one side of the PCB is designed with miniature high-power devices (≤2mm), and there are denser circuit graphics designs around the devices, which require communication with the inner layer; On the other side of the PCB corresponding to the micro high-power device area, the graphics design density is not high, but heat sinks need to be mounted to dissipate the large amount of heat generated by the micro high-power devices. [0003] The conventional PCB solution is to use heat-conducting plates and dense heat dissipation holes for high-power device areas, but the heat conduction effect of heat-conducting plates and dense heat-dissipating holes is not ...
