你好!DFM是其中一部分,其实这部分,设计和IE参与的更多。就我们品质部门而言,个人认为最为关键的是:
1. 客户或者说市场的需求是否清晰?有无不清晰或者错误的地方?
2. 历史上类似项目的不良是否能在新项目上面得到预防和改善?设计阶段这些都需要考虑进去;
3. 样品的验证规范是否全面,包括功能性、性能、安全、EMC、可靠性、外观、认证、环保等等,这些都需要有一个详细的检验规范,并能逐条去验证测试;
4. NPI阶段,新产品导入的时候验证产品的可制造型,稳定性等等;
5. 之前,我负责过8年研发设计和项目的品质,下面是工作中的一些内容,里面可能会更加具体点,当时用英文写的,仅供参考。
- 1)Assess the Marketing requirement, if it is enough or if any wrong, and work with team members together to optimize it. After get internal product specification, we also need to check it one by one, especially CTQ;
- 2)Collect all historical similar products quality issues and any other project risk issues, especially customer complaints and 8D reports, and share it with team members and do prevention in the new projects. And prepare the Field Experience report for the new Project;
- 3)Prepare the Quality Goal Definition for the new project, involve the DPMi, DPMe, OTDC, OTDS and others;
- 4)Push different team hold a DFMEA meeting internally, and hold regular DFMEA meeting with project team together, ensure the potential risks are resolved or reduced;
- 5)Assist the marketing to do AFMEA, to assess the potential application risk;
- 6)Review the product certification test standard, make sure the product meet it;
- 7)Assess the new design verification with R&D, try our best to find the potential risk, and make a detail verification plan, such as DFSS, ensure the tests are enough in order to make the product robust after launch;
- 8)During ETR, PTR ,Trail run, with team members together to confirm the production;
- 9)Make the PSVP (Product & System Validation Procedure), which include Function test, Safety test, EMC test, Reliability test, Mechanical test, Package test, Environment requirement (RoHS, Reach, WEEE), Certification and combine System & Software test;
- 10)Arrange a meeting with team members to confirm the PSVP, and arrange the test finally with test team members;
- 11)Follow up the test and review the test result, confirm it if has any issues;
- 12)Push the supplier provide mandatory documents and review it, and also audit the supplier production;
- 13)Arrange Filed test in internally (α- test) and in externally(β-test) with team members, follow up the test result;
- 14)If all OK, we will prepare PSVA (Product & System Validation Approval), previous called MP form, and release it through internal system;
- 15)Use SCAN & PQMA to assess the project risk during each Gate, prepare Fault tree if found high risk. Due to each Gate, we will prepare Gate report;
- 16)We also need to following up it even after MP. Besides, some above actions are continuous repeatedly.
