Engineering decision guide

PCB Assembly First Article Inspection Before Batch Release

Verify the first assembled result, document deviations and make an explicit release decision before the remaining quantity continues.

First assembled PCB separated from a small batch at a release checkpoint

Direct answer

Before batch release, confirm revision, part identity, fitted state, orientation, agreed workmanship evidence, programming and defined test results. Record every deviation and release authority.

FAI is a manufacturing release decision

Design validation asks whether the product meets engineering intent. First article inspection asks whether the released data, loaded parts, setup and agreed verification produced an acceptable first result before that result is repeated.

PCB First Article Release Gate

Identity

Match board revision, BOM, placement data, drawings, firmware and traveler to the released package.

Build evidence

Check fitted/DNP state, part identity, orientation, workmanship and agreed inspection evidence.

Product evidence

Run only the defined programming, measurement and functional checks with controlled limits.

Disposition

Release, hold or correct the remaining batch; record deviations, authority and evidence.

First Article Inspection Checklist

Review areaEvidence to reviewRelease questionHold condition
Revision identityBoard marking, fabrication outputs, BOM, CPL, drawings and change recordDo all artifacts describe one released build?Mixed or ambiguous revision
Part identityMPN, value, package, lot/date information where requiredAre fitted parts the approved identities?Unapproved substitution or unresolved package
Fitted / DNP stateBOM state, assembly drawing and first articleAre all and only intended designators fitted?Mismatch between data and physical assembly
Orientation / polarityDrawing, datasheet marking and physical resultDo polarized and oriented parts agree with the release?Any unresolved orientation
Workmanship evidenceSelected visual, AOI or X-ray records and agreed criteriaDoes evidence cover the defined risks?Required evidence missing or nonconforming
ProgrammingControlled image, version, checksum or programming log where applicableWas the intended image applied and identified?Version or method cannot be verified
Measurements / functionDefined sequence, safe limits and resultsDo recorded results meet released criteria?Limit, method or result is ambiguous
Deviation controlIssue list, concession/waiver, corrective action and ownerAre all departures accepted by authorized owners?Open issue has no disposition
Batch releaseSigned or recorded decision, date and evidence locationIs there explicit authority to continue?No named release authority

Minimum report fields

  • Project, assembly, revision and first-article serial or identifier
  • Released document set and revision
  • Inspection and test methods actually performed
  • Results, attached evidence and acceptance source
  • Deviations, disposition, owner and due date
  • Release / hold decision, authority and timestamp

Planning the first 100 units

Do not assume the first board, first panel or a fixed percentage is always the correct sample. Allocate units around process risk, destructive checks, firmware and test needs, then identify the point at which the remaining quantity may proceed.

Contract-specific criteria.

If IPC-A-610 or another acceptance document applies, identify the revision and class in the purchase documentation. This page does not claim Cyrionix certification or AS9102 compliance.
