【正文】 Yield rate study is also done here to determine optimum manufacturing parameter for ramp up to meet time to volume requirement. The major activities are: Pilot run and yield rate improvement MVT validation test, Regression verification test when needed Bug/deviation tracking and fixing Golden version software design Mechanical mold tooling approval Obtain regulatory certification Fixture and test program finalization NPI TPD document and file release Quality control plan After service related preparing The other requirement of 4M for manufacturing preparing MVT ( 4M : Man , Material , Machine , Method ) Main Flow of Product Development Specification ( H/W , Mechanical , S/W , Regulation … ) Schedule , Cost Product Design ( Hardware ) ( Mechanical ) ( Software ) Design Qualification Assurance ( DQA ) Design for Manufacturing ( DFM ) Design for Test ( DFT ) Design for Availability ( DFA ) Mass Production Manufacturing Quality Assurance ( MQA ) Design for Serviceability ( DFS ) Concurrent Engineering !!

Verification test It is conducted to verify the output meet input requirement in EVT and DVT phase, regression verification test is conducted when MVT output still has issues being able to meet input requirement ( For example – Function test , EMC Test , design margin test …. ) ? Validation test It is conducted to ensure that resulting product meets customer requirement for specified application usage or market end user intended use in DVT and MVT ( For example – ELP test , MTBF test ) Verification , Validation Test NPI ( New Product Introduction ) Plan and kickoff – Quality / Cost / Delivery / service MFG Process , test development , DFM/DFT Early involvement Material purchasing / Cost / Supplier management , DFA / VQA Material evaluation / Second source alternative Customer service , DFS NPI operation coordination , Design input , Quality requirement Logistic management and Sample build Project Charter SFIS (Shop Floor Information System) , Bug tracking system Engineering change management (ECN/ECR/ECRDesign) TPD document creation and management Phase gating Next phase MFG Quality control / Customer Quality Criteria Fail Pass MFG Process, Equipment and DFM MFG Testing And DFT Material control , DFA Sample Build After service And DFS MFG Quality Control Coordinator, Get design output data Input Material preparation DFA VQA PE / MD MP/VQA/CE ME / EQ TE PC/MC/HW/PD CS MQA Parts creation BOM creation H/W, S/W, Test code, Mechanical data input Quality requirement Coordination BOM cost Risk parts management Material purchasing
