1、 The raw materials are purchased, accepted and warehoused, and then produced according to the actual order quantity and specification of the customer.
2、 SMT: first, the PCB is pasted through the SMT machine.
3、 Plug in (DIP): the PCB with the attached piece is pulled on the plug-in to carry out the plug-in process. Dip will be subdivided into: plug-in, pressing, tin dipping, electronic foot cutting and other processes.
4、 Post soldering (repair welding): after the test is OK, pull the plug-in and tin the circuit board. Some electronic components have not been tin. At this time, post soldering is required to solve the problem.
5、 Kanban repair welding: wave furnace peak soldering: after the machine has welded the plug-in again and pulled it up, the electronic materials that have not been well tin when dipping tin are generally divided into areas, and then manually inspected to repair the parts that have not been welded in place.
6、 QC test 1: after manufacturing supporting test items. Test the bare board. If the test is OK, it will be sent to the next process. If the test is not passed, it will be repaired by the repairman;
7、 Assembly: this process is the most complicated and the most important one to test the level of production technology.
8、 Welding wire: weld the DC wire to the bare plate. Weld the AC line to the lower shell metal part of the shell.
9、 Gluing: glue the components and parts that simply fall and break during transportation. It passes through the solder joint of transformer, filter, AC line and DC line.
10、 Shell sealing: use ultrasonic wave to fix the shell finally.
