How does SMT processing factory ensure the quality of SMT processing
Some customers are worried about the quality of SMT processed products when they choose SMT chip processing factories. They want to know how the manufacturers can ensure that the quality of processed products meets the requirements. The following is an introduction to the Dongguan SMT chip processing factory through which methods to ensure SMT processing Quality.
1. Strict SOP production process control, SMT patch, DIP welding and back-end assembly test.
2. Professional technical team (engineer/technician working in smt industry for more than 10 years)
3. Complete incoming material inspection and confirmation process to check PCB and materials
4. The PCBA new model production project team checks the quality of the first production for new customers.
5. The first article confirmation process is rigorous, comparing PCB drawings, PCBA samples, etc., and final confirmation with the customer.
6. SMT patch processing and production process control: solder paste viscosity detection, solder paste printing thickness detection, patch accuracy detection, pre-furnace placement detection, regular sampling inspection after the furnace, full AOI inspection after the furnace, and finished product inspection.
7. The use of SMT accessories, Senju/Alpha solder paste, ensures the quality and stability of the patch soldering.
8. The equipment uses high-precision placement machine, the smallest placement is 03015, to ensure the accuracy and efficiency of SMT placement
9. The reflow soldering uses German REHM13 temperature zone reflow soldering to ensure the quality of the reflow stage and respond to various types of PCBA products
10. Nitrogen process and device storage, respond to pcba product customers with high requirements and high precision
11. SMT patch workshop environment monitoring: 25 plus or minus 2 degrees, relative humidity: 40%-60%
