How to audit a consumer electronics factory in Shenzhen.
PCB forensics, battery safety, counterfeit-component screening and CE / RoHS evidence — captured on the floor by an auditor who reads the bill of materials.
Why this sector breaks differently
Electronics factories fail in the BOM — not on the floor.
A consumer electronics OEM can pass a generic factory audit and still ship you a product that fails CE EMC, fails UN38.3 battery transport, or carries a counterfeit MCU. The risk in this sector lives in the bill of materials and the PCB process — not in the lobby.
Our forensic audits are run by auditors who can read a Gerber file, recognise a relabelled chip, and ask the right questions about reflow profiles. We treat the BOM as the primary evidence, not an annex.
Every audit captures CE, FCC, RoHS and battery-safety evidence in the same visit so your compliance file is complete the day the dossier is delivered.
What we audit
Five forensic checks specific to consumer electronics.
Counterfeit Component Screening
- MCU, memory and power-IC date-code and lot-trace verification
- Decapsulation or X-ray spot checks on high-risk parts
- Authorised distributor chain confirmed back to manufacturer
Battery & Power Safety
- UN38.3 transport test reports validated to current revision
- BMS / charging-circuit verification against schematic
- Cell supplier traceability and IEC 62133 evidence
CE / FCC / RoHS Evidence
- DoC, EMC and LVD test reports cross-checked against actual SKU
- Notified body identity and accreditation verified
- RoHS material declarations traced to homogeneous-material level
What you get
An electronics audit dossier you can defend in customs.
BOM-Grade Verification
Every critical component traced and photographed at lot-code level. No more relabelled MCUs slipping into your shipment.
Pre-Compliance Confidence
CE, FCC, RoHS and battery evidence captured in one visit and indexed to the audit dossier.
Defect-Mode Forecasting
Process audit identifies the three most likely failure modes for your specific design before mass production.
Counterfeit Risk Score
Quantitative red / amber / green score per critical component. Procurement decision-ready.
