PCBA manufacturing process:

SMT → DIP plug-in processing → PCBA testing → Finished product assembly

1

SMT: solder paste stirring→solder paste printing→SPI→SMD mounting→reflow soldering→AOI→rework.

Through SMT , components are mounted on the circuit board, and online AOI automatic optical inspection is performed if necessary. After inspection, set the perfect reflow oven temperature data and the board will go through reflow. After the necessary IPQC inspection, the plug-in material can be passed through the circuit board using the DIP plug-in process, and then flow through the wave soldering for soldering. After the above processes are completed, QA is also required to conduct a comprehensive inspection to ensure product quality.

DIP process: plug in → wave soldering → foot cutting → hand soldering processing → board washing → quality inspection.

PCBA testing: PCBA test can be divided into ICT test, FCT test, aging test, vibration test, testing in hard environment etc.

PCBA testing is the most critical quality control step to ensure the PCBA working **0%. It is necessary to strictly follow the PCBA test standards and test the points of the circuit board according to the customer's test plan.

Finished product assembly: Assemble the PCBA with enclosure, then test it, and finally it can be shipped.
