2. Build your own defect library

2.1 Lock parameters that affect the efficiency of the defect library

The No. 1 challenge of quality control is to decide on a product's level of conformity.

When the control method used is a comparison based on a defect library, it is essential to build this library in such a way that it is relevant and representative of the product characteristics to be obtained.

That's why, before building your defect library, you need to :
