3、s Verifies design has been correctly implemented into production CVT Compatibility Verification Testing产品定义(EVT)、产品设计(DVT),到定型测试(PVT)三大阶段是系统化产品研发流程。 70?!&DVT :Design Verification Test,是由开发样机阶段向生产样机阶段转换所必须的技术评审,DVT阶段:指从EVT评审通过后到DVT评审的阶段。包括模具测试、电子性能、外观测试等. 重点是确认:1、是否符合产品定义要求,2、可否批量生产,由项目部输出评审报告。PVT:Pr
4、oduction Verification Test,是由生产样机阶段向量产阶段转换所必须的技术评审,PVT阶段:指从DVT评审通过后到PVT评审的阶段。主要验证新机型的各功能实现状况并进行稳定性及可靠性测试。重点是确认:能否量产,由项目部输出评审报告。=EVT: Engineering Verification Test工程验证测试产品开发初期的设计验证。设计者实现样品时做初期的测试验证,包括功能和安规测试,一般由RD(Research&Development)对样品进行全面验证,因是样品,问题可能较多,测试可能会做N次。DVT: Design Verification Test 设计验证测
5、试解决样品在EVT阶段的问题后进行,对所有信号的电平和时序进行测试,完成安规测试,由RD和DQA(Design Qualiy Assurance)验证。此时产品基本定型。DMT: Design Maturity Test成熟度验证可与DVT同时进行,主要极限条件下测试产品的MTBF(Mean Time Between Failure)。HALT(High Accelerated Life Test)&HASS(High Accelerated Stress Screen)等,是检验产品潜在缺陷的有效方法。PVT: Pilot-run Verification Test 小批量过程验证测试,验证
6、新机型的各功能实现状况并进行稳定性及可靠性测试。MVT: Mass-Production Verification Test量产验证测试验证量产时产品的大批量一致性,由DQA验证。MP: Mass-Production 量产电子制造专业术语大集合Engineer 工程 PE: Products Engineer 产品工程 Process engineer 制程工程 TE: Test Engineer 测试工程 ME: Manufacturing Engineer 制造工程; Mechanical Engineer 机械工程 IE: Industrial Engineer 工业工程 DCC: D
