Look! PCBA production process

We have already introduced the relevant content of PCBA: PCBA refers to the process of mounting, plug-in and soldering of bare PCB boards. The PCBA production process must go through a strict and delicate process to complete. Speaking of production, I believe everyone is familiar with it, but how to produce and what the production process is, which is relatively unfamiliar. What is the PCBA production process? Let's take a look!


Look! PCBA production process

The PCBA production process can be divided into several major processes, SMT patch processing- DIP plug-in processing - PCBA testing- three anti-coating - finished product assembly.

PCBA production process

SMT chip processing
The process of SMT patch processing can be roughly regarded as: solder paste mixing - solder paste printing - SPI - placement - reflow soldering - AOI - rework


DIP plug-in processing link
The process of DIP plug-in processing is: plug-in-wave soldering-cutting feet-post-welding processing-washing board-quality inspection


PCBA test
PCBA test can be divided into ICT test, FCT test, aging test, vibration test, etc.
PCBA test is a big test. According to different products and different customer requirements, the test methods used are different. The ICT test is to detect the welding conditions of the components and the on-off conditions of the circuit, while the FCT test is to detect the input and output parameters of the PCBA board to see if it meets the requirements.


PCBA three-proof coating
PCBA three anti-coating process steps are: painting side A - surface drying - painting side B - curing at room temperature 5. Spraying thickness: spraying thickness: 0.1mm-0.3mm 6. All coating operations should not be lower than 16 degree Celsius and The relative humidity is lower than 75%.


Finished product assembly
After coating, the PCBA board that is tested OK is assembled for the shell, and then tested, and finally it can be shipped.

PCBA production process

As one of the emerging technologies, the PCBA circuit board, because it was born from aviation technology, naturally carries the characteristics of being rigorous and unable to cut corners. The PCBA production process that we introduced is naturally interlocking, and we must take care of each other.
