The process of DIP processing is: DIP → wave soldering → shearing → post-welding processing → washing board → quality inspection
(1)DIP
Insert the plug material into the pins and insert them on the PCB board.
(2)Wave Soldering
The inserted board is soldered by wave soldering. In this process, liquid tin is sprayed onto the PCB board, and finally cooled to complete the soldering.
(3)Cut the feet
The pins of the soldered board are too long to be cut.
(4)After welding processing
Manual soldering of components using an electric soldering iron.
(5)Wash the board
After wave soldering, the board will be dirty, cleaned with wash water and wash tank, or machine cleaned
(6)Quality inspection
Inspection of the PCB board, unqualified products need to be repaired, qualified products can enter the next process.
