Frequently Asked Questions (FAQ)

Does YYE provide PPAP documentation?

Yes, we provide full PPAP (Production Part Approval Process) Level 3 documentation, including DFMEA, PFMEA, and control plans, to ensure compliance with automotive requirements.

What testing do you perform on automotive harnesses?

We perform 100% electrical testing, visual inspection via AOI, pull-tests for all terminals, and environmental stress screening (temperature/humidity cycling) upon request.

Can you help with component sourcing to reduce costs?

Absolutely. We offer a "Hybrid Sourcing" strategy—using original brand-name connectors for critical interfaces while suggesting high-performance, cost-effective alternatives for non-critical housings.

What is your minimum order quantity (MOQ) for custom automotive projects?

We support the entire lifecycle, from small batches for specialty vehicle prototypes (MOQ as low as 100-500 pcs) to high-volume annual contracts for mass production.
