IEC 61193-2-2007
摘要:
This part of IEC 61193 applies to the inspection of electronic components, packages, and alsomodules (referred to as “products” in this standard) for use in electronic and electricequipment. It specifies sampling plans for inspection by attributes on the assumption that theacceptance number is zero (Ac = 0), including criteria for sample selection and procedures.The zero acceptance number sampling plans provided by this standard apply to the inspectionof products, that are manufactured under suitable process control with the target of a “zerodefect”quality level before sampling inspection.In addition, this standard provides a method for the calculation of the expected value of thestatistical verified quality limit (SVQL) at a confidence level of 60 %. Amongst other things,this method can be used to verify the effectiveness of the supplier’s process control.NOTE In this standard the term “module” is used for products which are modules according to the definition inIEC 60194.
