传递特性的管理概要第1页/共25页WhatisPassThroughCharacteristics?

（什么是传递特性）PassThroughCharacteristicsarethoseinternalandexternalsuppliedcharacteristicswithpotentialfitorfunctionissuesthatwillnotget100%detectedwithinaproductionassemblyandtestarea(essentiallyanywhereverifiablewithinaplant.)Qualitydefectsarethereforeatriskofbeing“PassedThrough”toourcustomers.传递特性就是那些内部或者外部供应产品的特性的潜在的或运行的问题在生产装配和检测时（车间内部任何一个能做验证的）没有被100%的识别，因此就存在质量缺陷被“传递”到我们的客户那里的风险。第2页/共25页PassThroughCharacteristicManagement
