A supplier is compressions molding a silicon part. For this production process I am thinking of creating/ calculate PPM (Parts Per Million). Since supplier manufacturer 10,000 to 20,000 parts per lot, its not feasible to visually check every part in the lot for defective units to calculate the PPM Can you give me guidelines on selecting samples from the lot to calculate the PPM. -
