Embodiment 1

[0017] First apply heat dissipation glue on the heat dissipation plate, apply bonding glue on the bracket, then assemble the regulator bracket, heat dissipation plate, IC, and PCB components, and then use equipment to spot solder paste on the parts that need to be soldered, use fixtures to fix them, and then put them into reflow In the furnace, through the use of a reflow furnace, soldering IC, soldering PCB and brackets, soldering external electronic materials, curing heat dissipation glue and bonding glue are achieved. The assembly process simplifies the process, reduces the investment of personnel and equipment, improves the welding quality, and does not have tin beads.

Embodiment 2

[0019] First apply heat dissipation glue on the heat dissipation plate, apply bonding glue on the bracket, then assemble the regulator bracket, heat dissipation plate, IC, and PCB components, and then use preformed solder pieces at the places that need to be soldered, fix them with jigs and put them into reflow In the furnace, through the use of a reflow furnace, soldering IC, soldering PCB and brackets, soldering external electronic materials, curing heat dissipation glue and bonding glue are achieved. The assembly process simplifies the process, reduces the investment of personnel and equipment, improves the welding quality, and does not have tin beads.
