Quality Control

1. Material checking: Quality control on new materials, to sort out the qualified and rejected materials before production.
2. Chip testing: we purchase chips and test every chip stability and quality.
3. Semi-finished products testing: Make all chips which pass first tests to semi-finished products by SMT machine and test those semi-finished products.
4. Finished products testing: Assemble all the USB flash drives, and test all products by H2 test.
5. QC spot checking: Randomly choose the USB flash drive and check the quality from the mass production.
