What the 11 Pages Document
This sample records the final inspection of one 92-piece bare PCB lot dated May 20, 2025. The outgoing audit uses AQL 0.4 where sampling applies and records the requirement, actual reading, and acceptance decision for each check.
1. Compliance and lot identity
The certificate of compliance identifies UL file E315835, FR-4 TG material, 94V-0 flame class, RoHS status, lot quantity, date code, and ship date.
2. Outgoing audit summary
The audit sheet consolidates material, plating, solder mask, legend, circuitry, hole, profile, reliability, electrical, visual, and environmental checks with an ACC result.
3. Dimensional records
Dedicated pages record finished hole diameters, 56 drawing dimensions, overall board thickness, and component-side and solder-side trace width and spacing.
4. Electrical and microsection evidence
The lot received a 100% electrical test. Microsection records document PTH copper thickness, hole-wall roughness, layer copper, finished surface copper, and solder mask thickness.
5. Reliability checks
The report includes solderability and thermal-stress conditions, observed results, final acceptance, inspector, approver, and test date.
How to Read This PCB Inspection Sample
The figures below are transcribed from the embedded report so buyers can understand the document before opening the full PDF.
| Check | Requirement in this sample | Recorded result |
|---|---|---|
| Finished board thickness | 1.60 +/- 0.16 mm | 1.58-1.67 mm, accepted |
| PTH copper thickness | 20 um minimum at a point, 25 um average | 25.3-29.9 um, accepted |
| Solder mask thickness | 15 um minimum | 29.8-29.9 um, accepted |
| Trace width and spacing | Drawing values with +/-20% tolerance | 0.19-0.21 mm readings, accepted |
| Ionic contamination | 6.4 ug NaCl/sq. in. maximum | 0.020 ug NaCl/sq. in., accepted |
| Electrical test | 100% of the 92-board lot | 92 passed, 0 failed |
| Solderability | More than 95% good wetting at 260 +/- 5 C | Even solder on both sides, accepted |
| Thermal stress | 288 +/- 5 C, three 10-second cycles | No listed defects observed, accepted |
Scope note: This is a bare PCB outgoing inspection example, not a universal specification or a PCBA functional-test report. Inspection criteria and deliverables must follow the applicable drawing, finish, industry standard, purchase order, and agreed quality plan for each project.
Tests Shown in This Sample
The sample combines measured results and signed acceptance records rather than relying on a single pass/fail statement.
Dimensional & Hole Measurement
Finished dimensions and drilled-hole readings are compared with the drawing requirements and recorded per sample.
100% Electrical Test
The electrical report records continuity, insulation, test voltage, sample size, passed quantity, and failed quantity.
Microsection Analysis
Destructive testing to verify plating thickness, hole wall integrity, and layer registration.
Solderability & Thermal Stress
Solderability and thermal-stress pages state the test conditions, observed results, acceptance decision, and sign-off.
Full Traceability for Critical Industries
Quality documentation should match the risks and acceptance criteria of the project. We retain batch-specific inspection records according to our quality procedures and agreed customer requirements, so the shipment can be traced back to its lot, date code, measured results, and approval record.See our inspection methods.
