Electronics Inspection in China
It works on the factory bench and fails in the field. Our IPC-certified inspectors in Shenzhen power the samples up, burn them in for eight hours, and read the solder joints.
We once passed a batch of 2,000 Bluetooth speakers that had a 2% failure rate on the pairing function — a test we hadn't included in our standard checklist. 40 customers received speakers that wouldn't connect. We rebuilt our entire electronics checklist that week.

A $268 Pre-Shipment Inspection caught critical wiring defects in 3,000 LED desk panels destined for Amazon FBA. The factory's own QC team had passed the lot. After rework and re-inspection, the seller shipped with confidence and generated $150,000+ in revenue with zero quality complaints.

FAQ
Frequently Asked Questions
Housing defects (31%), soldering (24%), wrong components (18%), cable issues (16%), display (14%). Electronics average 4.7 distinct defect types per failed inspection.
We recommend a tighter-than-standard 0 / 1.5 / 2.5 plan for electronics: zero tolerance for critical safety and function failures, 1.5 for major defects that affect usability, and 2.5 for minor cosmetic issues. This has delivered a 34% improvement in customer satisfaction versus the common 0 / 2.5 / 4.0 plan.
It depends on your destination market. For the US: FCC for radio-frequency emissions plus UL/ETL safety listing. For the EU: CE (LVD + EMC), RoHS, and REACH. Internationally, IPC-A-610 governs soldering workmanship. We coordinate the required compliance testing through CNAS / ISO 17025-accredited partner labs.
Yes. Our electronics protocol includes an 8-hour burn-in test to surface intermittent failures that a quick power-on check would miss, alongside functional power-on testing of every feature, wireless connectivity checks, and battery capacity verification.
