Dip plug-in process during PCBA production


The PCBA manufacturing process in the production workshop of PCBA manufacturer is: material preparation → first article → plug-in → PCBA furnace passing → post welding (holding tin) → plate washing → burning → PCBA test → finished product packaging.


1. The post welding in the production workshop of PCBA manufacturer is to strengthen the process of adding tin to the components on PCBA after SMT technology equipment furnace process. The plug-in is to insert the plug-in material into the corresponding plate hole of PCBA;

2. The SMT patch processing technology workshop of PCBA manufacturer must meet the requirements of people, materials and relevant operation instructions before using dip plug-in for production;

3. The capacity of post welding is 450 per hour, and the employees work in 400 quantities;

4. PCBA technical equipment solder paste machine tin: after passing the furnace, SMT operators fill some dip plug-ins with tin on the pull-up; Tin penetration process is a special dip plug-in process that needs to penetrate from one side to the other when tin is added;

5. According to the requirements, take the material as the required shape to form the material, such as inductance, diode, capacitor, etc;

6. The maximum production limit of wave soldering energy of equipment in PCBA technology workshop is 450mA and the minimum is 20mm '

7. The customer needs the chip processing plant to do virtual function test, and the PCBA manufacturer's business needs to provide production test conditions (software, data, performance, voltage, current, etc.);

8. After the PCBA of dip plug-in has been heated, SMT relevant staff need to check each dip plug-in component one by one, and then add tin to some special components;

9. The component materials on PCBA are sharp materials that are larger than plane patch materials, such as diodes, capacitors, collectors, connectors, resistors, etc.
