　　1. The raw materials are purchased and checked into the warehouse, and then the materials are collected and produced in a unified manner according to the actual order quantity specifications of the customers.

　　2. Mounting (SMT): First, pass the PCB through the SMT machine for the mounting process.

　　3. Plug-in (DIP): The PCB is pasted, and the plug-in is pulled up to perform the plug-in process. DIP will be subdivided into: plug-in, pressing parts, immersion tin, cutting electronic feet and other processes.

　　Fourth, post soldering (repair soldering): After the test is no problem, pull on the plug-in, the circuit board after immersion tin, and some electronic components have not been tinned well. At this time, post soldering is required to solve it.

　　V. Kanban repair soldering: wave soldering: After the machine is soldered again, the plug-in is pulled up, and there is no electronic material that is tinned during the immersion tin. Generally, a PCB is divided into areas, and then the parts that are not soldered in place are manually checked. Repair welding.

　　Sixth, QC test 1: After manufacturing matching test tools. Test the bare board, if the test is OK, go to the next process, if the test fails, then repair it to the repairer;

　　7. Assembling: This process is the most complicated, and it is also the process with the most inspection and production process level.

　　8. Welding wire: Weld the DC wire to the bare board. Solder the AC wire to the lower metal part of the shell.

　　9. Gluing: Gluing the components that are simply dropped or broken during transportation. Pass through solder joints with transformers, filters, AC lines and DC lines, etc.

　　Ten. Sealing: Use ultrasonic to finally fix the shell.

　　11. Paste the nameplate: After the appearance inspection is no problem, the laser engraves the corresponding label.

　　12. Aging test: Transfer to the aging workshop for an aging test. After the aging test for a certain period of time, it will be transferred back to the assembly to do the final full inspection QC test, and a test report will be issued.

　　13. Packaging: Finally, the knife card carton is packed into the warehouse and enters the state of waiting for shipment.
