IQC: after receiving delivery note from the warehouse, check the SIP data and inspect incoming material;
IPQC: inspect the appearance/size/function of the first article before producing according to the SIP quality standard, production only can be confirmed as long as the article is qualified. We check the appearance/size/function one shift every two hours and fill in the inspection forms according to the result.
OQC: when all the packing are ok, we do AQL selective inspection. The qualified will be arranged to be dispatched, otherwise they will be returned to rework. They can only be shipped until the sampling inspection of the mass production is okay.
