How many steps are there in the process of DIP plug-in processing?

With the rapid development of SMT processing technology, SMT patch processing has gradually replaced DIP insertion processing. However, due to the oversize of some electronic components in PCBA production and other reasons, plug-in processing has not been replaced. Still, it plays an essential role in the electronic assembly process. DIP plug-in processing is after SMT patch processing, and generally uses assembly line manual plug-in, which requires a lot of employees.

The process flow of DIP plug-in processing can generally be divided into: component forming processing → plug-in → wave soldering → component cutting → repair welding (post-welding) → board washing → functional testing

1. Pre-processing the components

First of all, the staff in the pre-processing workshop go to the material place to pick up the materials according to the BOM material list, carefully check the material model, and specification, sign, and perform pre-production pre-processing according to the model, using automatic bulk capacitor cutting machine, transistor automatic molding machine, fully automatic Forming equipment such as belt forming machines for processing.

2. Plug-ins

Insert the chip-processed components into the corresponding positions on the PCB board to prepare for wave soldering.

3. Wave soldering

Put the inserted PCB board into the wave soldering conveyor belt, and complete the soldering of the PCB board after spraying flux, preheating, wave soldering, cooling, and other links.

4. Component cutting feet

Cut the feet of the soldered PCBA board to achieve a suitable size.

5. Repair welding (post-welding)

Repair welding should be carried out for maintenance for finished PCBA boards that have not been completely welded after inspection.

6. Washing plate

Clean the harmful substances such as soldering flux remaining on the finished PCBA to meet the cleanliness of the environmental protection standard required by the customer.

7. Function test

After the components are soldered, the finished PCBA board needs to be functionally tested to check whether the functions are normal. If a functional defect is detected, it needs to be repaired and retested.
