How to Qualify a Fan Vendor ?
1. Quality control system (ISO9001, C=0, SPC, Noise, Balance...)
2. Production capacity (Tooling, Lines)
3. Delivery (Lead Time)
4. Service (QA team, Location...)
5. Safety Approval (UL, CSA, TUV, CE...)
6. Specification (Dimensions, rpm, PQ, Sound, Signal...)
7. Patent authorized (Patent Infringe, Papst…)
8. Reliability test (Accelerated life, Shock, Vibration...)
9. RD capability (Impeller, Motor, PCB design)
10.Green Partner (Without pollution material and process)
