Quality control is more than just inspection; it is also about meeting the yield target through inspection.
Yield managemant & NPI (New Product Introduction)
Before launching a new product, the yield rate is determined by the manufacturing process and process technology stability. Yields must be carefully considered and tested from product design and NPI (New Product Introduction) to the manufacturing end to avoid error resolution and stability.
The role of manufacturers
Manufacturers must follow the manufacturing process and procedures beginning with FAI, and the equipment parameters, including production tools, inspection methods, and the size NG and appearance NG, must be decided in the first round.
Quality control must focus on yield improvement
Quality control inspection unit inspection results show NG, which absolutely cannot be because of a specific size NG is an occasional incident and do not pay attention to, resulting in a high defective rate, and thus increasing the number of production, which is the most unwise decision.
Be realistic and thoroughly solve the causes of process technology NG
As a result, we must be realistic and thoroughly solve the causes of process technology NG, rather than shifting production costs and risk management to customers, not to mention inspection for the sake of inspection, in order to identify and correct problems as soon as possible.
