These chips are incorporated into analog devices that are then encased in epoxy. The yield is not particularly good for LSI manufacture, so the AQL specified by that department is 17% while the LTPD acceptable by the assembly department is 47%. Assume the company is willing to accept a consumer's risk of 10 percent and a producer's risk of 5 percent. a. Find the sample size. Use Exhibit 13.10. Note: if the exact value of the computed LTPD/AOQ ratio does not appear in Exhibit 13.10, use the next higher ratio. (Round up your answer to the next whole number.) Sample size b. How would you tell someone to do the test? Randomly sample LSI using the sample size from part a, the lot if more than defective
