We know that the processing technology of PCBA production and processing is related to the quality of PCBA products and is an important link in the whole process of PCBA production. In layman's terms, PCBA process (PCBA processing technology) means the integration of SMT production process and DIP production process. According to different production process standards, the PCBA process can be divided into single- and double-sided SMT patch process, single-sided DIP insertion process, single-sided mixed process, single-sided patch and insertion mixed process, etc.

The PCBA process involves the entire process of carrier board, printing, patching, reflow oven, plug-in, wave soldering, testing and quality inspection. Different types of PCB boards have different processing techniques. The following Sanjing will be introduced for everyone:

1. Single and double-sided SMT patch. Add solder paste to the component pads. After the solder paste printing on the bare PCB is completed, go through the reflow oven for patching, and then do the reflow oven for manual soldering.

2. Single and double DIP inserts. It is necessary to pass the completed plug-in PCB board through a wave soldering machine, and after the manual soldering is determined, cut the feet and wash the board. However, the wave soldering machine generally has a low productivity.

3. Single and double-sided mixed. The PCB board is printed with solder paste, and the electronic components are mounted and then manually soldered in the reflow oven. After the quality inspection is completed, the DIP plug-in is done. If there are fewer through-hole electronic components, manual soldering is recommended.

4. Single and double-sided patch and plug-in mixing. Some PCB boards are double-sided, one side is patched, and the other side is inserted. The processing technology of patch and inserting is the same as single and double-sided production and processing, but the PCB board needs to use jigs to pass through the reflow oven and wave soldering machine.

The above content is about the type and production process of PCBA process, I hope it can be helpful to everyone!
