Direct PCBA engineering and component verification across Shenzhen and the Greater Bay Area. We trace critical BOM lines to approved supply channels, audit SMT placement controls, supervise buyer-specified functional and burn-in testing, and protect controlled firmware releases—reducing counterfeit-component and silent-substitution risk before box build.
Physical evidence across component receiving, PCBA production, revision control and finished-product inspection.
Challenge the source and identity of critical semiconductors before reels reach the placement line.
Verify that the process records behind a clean production floor are active and product-specific.
Keep the released binary, programming quantity and board revision aligned throughout production.
Confirm that buyer-specified tests are powered, timed, recorded and linked to the production lot.
These representative field decisions show the evidence and escalation logic. Visual anomalies alone do not prove counterfeiting; suspect material is quarantined until documentary or laboratory evidence resolves it.
The approved BOM called for an STMicroelectronics MCU. IQC found inconsistent reel markings, light lead oxidation and date codes spanning three years, while the supplier could not provide an acceptable chain-of-custody record for the received lot.
The recorded lead-free reflow peak was 6°C below the approved paste profile, and X-ray review found excessive voiding in 3 of 10 sampled BGA locations.
Wi-Fi/BLE gateways, smart plugs and sensor products.
Control focusRF performance, antenna assembly, firmware identity and certification-sample consistency for the target CE/FCC pathway.TWS accessories, power banks, chargers, hubs and compact connected devices.
Control focusBattery cell identity, MSDS/UN38.3 transport evidence, charging protection, enclosure fit and cosmetic control.Control boards, sensor modules, motor drives and low-volume engineered assemblies.
Control focusBOM revision, conformal-coating coverage, connector retention, traceability and specified thermal or environmental operation.Certification support means checking the production configuration against the buyer’s declared target and available evidence. It does not make Jaime Sourcing a certification body or guarantee regulatory approval.
We agree what success looks like before starting. Findings are separated into facts, risks and recommended actions so your team can move quickly.
Electronics inspection scopes are built from the released BOM, Gerber/revision package, firmware version and buyer-approved test specification. Tests and sampling cannot be inferred from a product photo or generic checklist.
Review the BOM, Gerber package, approved alternates, board revision, firmware release, compliance target and ICT/FCT acceptance criteria.
Verify the legal supplier, component channels, SMT capability, process ownership and confidentiality controls before purchase commitment.
Lock the Golden Sample or pilot build; reconcile critical reels, first-article results, solder profile and programmed firmware version.
Inspect functional-test records, burn-in execution, finished-product appearance, accessories, labels, battery documents and export packaging before release.
Challenge the source and identity of critical semiconductors before reels reach the placement line.
Verify that the process records behind a clean production floor are active and product-specific.
Keep the released binary, programming quantity and board revision aligned throughout production.
Confirm that buyer-specified tests are powered, timed, recorded and linked to the production lot.
