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.

CASE STUDY
Failed Lot Caught at PSI
Electronics Importer (Austin, TX, USA)
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.
