Acceptance based on product risk

PCBA Testing & Inspection Services

PCBA testing services including visual inspection, AOI, X-ray, ICT and functional test planning based on design risk and acceptance criteria.

What this service solves

A controlled path from requirements to acceptance

No single test method proves every assembly is good. Test coverage should be selected according to component visibility, circuit access, failure consequence and the customer’s acceptance requirements.

Best fit for

  • Boards with hidden-joint packages
  • Products requiring electrical or functional screening
  • Programs needing documented acceptance records

Scope

Typical project deliverables

The exact scope is frozen in the quotation and approved build documentation.

Workflow

How a build moves forward

  1. 01

    Qualification

    Confirm product stage, quantities and commercial fit.

  2. 02

    File review

    Identify missing data and manufacturability conflicts.

  3. 03

    Quotation

    Separate material, fabrication, assembly, test and logistics assumptions.

  4. 04

    Approval

    Freeze revisions, alternates and acceptance criteria.

  5. 05

    Build & validation

    Manufacture against the approved package and record agreed results.

Risk review

Issues to resolve early

RiskRequired control
Claiming 100% coverage without a coverage analysisResolve conflicting inputs in a dated engineering review.
Testing without pass/fail limitsRecord approval ownership and release status before purchase.
No ownership for fixture maintenanceDefine handling, traceability and exception rules in the build package.
Rework without retest rulesSelect inspection and test coverage against the actual failure risk.

Buyer questions

Frequently asked questions

What is the difference between AOI and X-ray?

AOI inspects visible features such as placement and solder joints. X-ray is used for hidden joints and internal solder features that optical systems cannot see.

Who supplies the functional-test procedure?

The customer normally defines product behavior and acceptance limits. The manufacturer can help translate that into a repeatable fixture and production procedure.

Does every board need ICT?

No. ICT feasibility depends on test access, volume, fault coverage and fixture economics. Other combinations may be more appropriate.
