Quality Assurance System
Our quality assurance system entails the thorough examination of the specifications and quality levels expected and demanded by our customers, as well as forecasting market trends and initiating investigations by all related departments, including the Design Department and the Quality and Reliability Department, for the purpose of creating viable plans. We place particular emphasis on quality and reliability built into the product from the development stage. Having verified this with our DR (Design Review,) we move onto the stages that incorporate the production of prototypes and then mass-production followed by delivery to our customers.
- Simulation
- Process and package reliability verification tools: PRS, APRS
- Design reliability verification tool: DRS
Creation of faulty mechanism models, life-span evaluations and fault analysis
- We have established cross-functional teams for products that are to be mounted in automobiles and adopted an Anticipated Product Quality Planning (APQP) system to pinpoint risks in the initial development stage, initiate thorough verification and then move onto mass production.
- Prevention activities from the development stage by effectively utilizing Fault Mode Effect Analysis (FMEA)
- Regular reliability monitoring
- Building quality into the produts at the mass production stage
- Small-group activities (dust eradication, improved yields, cost reduction, quicker TAT (delivery), etc.)
- Risk dispersion through parallel production (promotion of a supplementary production system between production bases)
