Large-scale integrated (LSI) circuit chips are made in one department of an electronics firm. 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. Use Exhibit 10.16.
