Every single unit — not a sample — is visually inspected, dimensionally verified and cross-checked against a full history of test data before it's packaged and released. No board leaves without a documented pass.
Upstream tests find electrical faults. Final inspection is where everything else gets caught. Hover to explore.
Solder joint quality, tombstoning, insufficient wetting, flux residue and silkscreen legibility checked under magnification against IPC-A-610 criteria.
Wrong label, mismatched barcode, incorrect quantity per reel or tray, and packaging materials verified against the PO and BOM before sealing.
Gaps in the certificate of conformance, material certifications or test report set are flagged before a shipment is allowed to leave the building.
Loose or under-torqued hardware, poorly seated connectors, missing standoffs and mechanical fit problems caught before final packing.
MSL-rated components verified for correct floor-life exposure, then sealed in moisture barrier bags with desiccant and humidity indicator cards.
Every unit's AOI, X-ray, ICT and functional test records are reconciled — any missing or inconsistent record halts the release.
Board bow and twist, thickness and outline dimensions re-verified against drawing tolerance immediately before packing.
Revision markings, date codes and part markings cross-checked to prevent an outdated or mixed revision from ever reaching a customer.
Final inspection is not a single check — it's the consolidation point where every prior test result, every visual pass and every packaging step comes together into one shipping decision.
Results from every upstream station — AOI, X-ray, ICT, flying probe and functional test — are pulled and reconciled against the unit or lot serial number before any physical inspection begins.
AOI · X-ray · ICT · flying probe · functional testEvery unit is inspected under magnification against IPC-A-610 Class 2/3 workmanship criteria — solder joint quality, component placement, silkscreen legibility and conformal coating coverage — along with board warpage, connector seating and standoff height.
IPC-A-610 · 10× magnification · 100% coverageLabel content, barcode and quantity are checked against the PO and BOM. ESD-safe packaging materials are verified for the correct part before any unit is bagged, boxed or reeled.
ESD-safe packaging · label vs. PO/BOM auditMoisture-sensitive assemblies are sealed per J-STD-033 in moisture barrier bags with desiccant and a humidity indicator card. ESD packaging is verified per ANSI/ESD S20.20 before handoff.
J-STD-033 · ANSI/ESD S20.20Test reports, certificates of conformance and material certifications are compiled into a single traceable document package for the shipment or lot — ready for customer incoming inspection.
CoC · test reports · material certsA dedicated OQA reviewer performs a final spot-check and signs off before release. Defect trend and yield data from the shipment is fed back to production engineering for continuous improvement.
OQA sign-off · yield & defect trend feedbackEvery criterion applied at final inspection is traceable to a written standard — not operator judgment.
Every board is inspected under magnification against IPC-A-610 Class 2 or Class 3 acceptance criteria — solder joint fillet quality, component placement and alignment, silkscreen legibility, and conformal coating coverage where specified.
ESD-safe packaging is used throughout per ANSI/ESD S20.20. Moisture-sensitive devices are sealed in moisture barrier bags with desiccant and a humidity indicator card per J-STD-033, with correct floor-life labeling on the outer packaging.
Every shipment ships with a bundled document package: certificate of conformance, all upstream test reports, material and RoHS/REACH certifications, and lot-level traceability records — organized per shipment or lot so your incoming inspection team can verify in minutes.

Final inspection is where our entire quality system converges. Every certification we hold and every upstream test method feeds into the OQA sign-off before a shipment leaves the building.
Real defects final inspection stopped before they reached a customer.
A packaging label mismatch on a Tier-1 automotive lot was flagged during final inspection's PO/BOM cross-check, before the shipment left the warehouse.
Discrepancy caught before dispatch, full lot relabeled and re-verified within 24 hours. Customer never saw a mislabeled unit.
Final inspection added a dedicated MSL floor-life check for a Class II medical device program, sealing every reel per J-STD-033 with humidity indicator verification.
Program passed customer quality audit with zero findings related to moisture-sensitive handling, citing the documented MSL process as best-in-class.
Recurring in-transit damage claims on a heavy industrial assembly were traced to inadequate cushioning during final inspection review of returned units.
New packaging spec rolled into standard OQA checklist. Transit damage claims dropped by 85% over the following two quarters.
A final inspection stamp is only as good as the process behind it. Ours combines 100% unit coverage, documented standards and a dedicated audit gate — not a rubber stamp on a sampling plan.
We don't rely on AQL sampling at final inspection. Every single board is visually and dimensionally checked before packaging — the only way to guarantee zero surprises at your incoming dock.
Certificates of conformance, test reports and material certifications are bundled and delivered within 24 hours of release — ready for your own incoming inspection team.
We track defect escape rate as a formal KPI, feeding every finding back into production engineering to drive the number down shipment after shipment.
Final release requires sign-off from a quality reviewer independent of the production line — an extra layer of accountability standard on every order, at no added cost.
Common questions about final inspection and 100% outgoing quality control.
AOI, X-ray, ICT and flying probe each verify one specific aspect of a board — placement, solder joints, or electrical continuity — at a single point in the process. Final inspection happens last and covers everything those methods don't: cosmetic workmanship, packaging accuracy, documentation completeness, MSL/ESD compliance, and a review that every prior test record is present and passing. It's the consolidation step, not a replacement for upstream testing.
100% — every unit, not a statistical AQL sample. Each board is visually and dimensionally inspected under magnification, and its full test data history is reconciled before it's cleared for packaging. Sampling plans are appropriate for some incoming material checks, but not for outgoing quality control on finished assemblies.
Yes. Every shipment includes a certificate of conformance along with the compiled test report set, material certifications and lot-level traceability documentation. The full package is bundled and delivered within 24 hours of final release.
MSL-rated assemblies are sealed in moisture barrier bags with desiccant and a humidity indicator card per J-STD-033, with floor-life and MSL level clearly labeled on the outer packaging. All packaging materials are also ESD-safe per ANSI/ESD S20.20 for boards with static-sensitive components.
The affected unit or lot is held and does not receive OQA sign-off. Depending on the finding, it's routed to rework, re-test, or scrap, and the root cause is logged and fed back to production engineering as part of our defect trend reporting — so the same issue is less likely to recur on the next run.
Yes. We regularly align our final inspection checklist and documentation package to match a customer's own incoming quality requirements — including specific IPC class, additional dimensional checks, or extra certificates — so your receiving team can clear shipments faster.
