Double-sided PCB capable of being adjusted according to height of electronic component

The utility model relates to the technical field of double-sided PCBs (printed circuit boards), in particular to a double-sided PCB adjustable according to the height of an electronic component, which comprises a mounting plate and heat-conducting silicone grease, the heat-conducting silicone grease is adhered to upper and lower grooves of the mounting plate, and adjusting devices are mounted on the left and right sides of the mounting plate. The second nut can be installed on the screw rod, then the cover plate is driven to move to the concentric-square-shaped groove of the installation plate, meanwhile, the cover plate drives the vertical plate to move to the screw rod, the first nut is installed on the screw rod, in this way, the first nut is matched with the second nut to fix the vertical plate, and meanwhile the position of the cover plate can be adjusted according to the height of an electronic element. In this way, the first PCB and the second PCB can be used with electronic elements with different hei
