Error correction and recheck of electronic components.

After the electronic components are inserted into the PCB, the targeted recheck of the inserted electronic components on the PCB will be carried out by full-time personnel which ensure that it has no wrong parts, no missing parts, no damaged parts and no dislocation. 

1. Wave soldering. After the recheck, the PCB circuit board with inserted electronic components will needs to undergo two wave soldering

2.Recheck again. After the wave soldering is finished, the targeted recheck of the welded PCB circuit board will be carried out by full-time personnel,which ensure that it has no missing soldering, no false soldering and no continuous soldering
