Factory Burn-In Testing: What Buyers Should Expect

Burn-in catches early fan, PSU, and USB path failures before cartons leave Guangzhou. **Standard scope (when ordered):** - Power-on every slot - USB/data path check control PC → hub → node - Loaded run duration depends on product class — stated on packing checklist - Fan noise and temperature spot-check **What burn-in is not:** It does not replace your app-level soak test with production accounts. It validates hardware assembly, not your campaign logic. **Documentation:** Buyers can request checklist sign-off or summary note for audit — specify on RFQ for enterprise deals. **Skip burn-in:** Possible on rush samples by agreement; trade-off is higher DOA risk in your first week. Include "burn-in required" in Contact if procurement mandates pre-ship load testing.
