Quality & Traceability

PCB & PCBA Quality Control

Quality control connects incoming materials, build revisions, inspection results and defect follow-up. Define which units each record covers and how failures are corrected before shipment. For selecting ICT, flying probe or functional testing, use the dedicated testing service page.

Where inspection fits into a PCB assembly build

The image shows a typical inspection task; the steps below explain the separate checks to agree for your build, from incoming materials through final release.

  1. 01

    Incoming Inspection

    Check materials, components, labels, quantities, packaging and project documentation.

  2. 02

    Process Control

    Control fabrication, solder-paste printing, placement, reflow and agreed process requirements.

  3. 03

    Inspection & Testing

    Apply SPI, AOI, X-Ray, electrical testing, ICT or FCT according to the agreed scope.

  4. 04

    Final Inspection

    Confirm workmanship, labeling, documentation, packing and shipment-release requirements.

  5. 05

    Records

    Maintain the agreed production, inspection and test records for the project.

  6. 06

    Shipment Release

    Release only after final acceptance and packing requirements are met.

Quality control connects the checks to the build

Keep the board revision, material lots, inspection results and open defects linked to the same build. A test result describes one check; the quality record explains which units it covers and what happened to failures. This page covers that production record and follow-up process.

Inspection Systems

PCB Inspection & Testing Capabilities

Inspection and test methods are selected according to package type, process risk, test access and the agreed acceptance plan.

AOI inspection machine

AOI Inspection

3D AOI checks visible placement, polarity, component presence and solder-joint features. Coverage and limits are confirmed for the selected line and project.

PCBA inspection and testing equipment

3D SPI

3D SPI checks solder-paste height, area and volume before placement. The inspection recipe and acceptance limits are defined for the released assembly.

X-Ray inspection equipment

X-Ray Inspection

X-ray examines hidden joints beneath BGA, QFN and CSP packages when the agreed inspection plan requires subsurface evidence.

PCB testing equipment production line

Electrical Test & ICT

Electrical test or flying probe checks opens, shorts and net continuity. ICT is available with appropriate bed-of-nails or flying-probe coverage.

Precision PCB inspection and testing equipment

FCT, Burn-In & JTAG

Functional test, optional aging and boundary scan are selected according to approved procedures, fixtures and acceptance criteria.

PCB fabrication inspection equipment

PCB Fabrication Inspection

Fabrication inspection supports process verification before assembly or final release.

Traceability and Quality Records

Traceability is planned from the released configuration and the agreed project, facility and sourcing scope. Record level, retention, retrieval and change-control responsibility are confirmed before release; they are not implied by a generic service label.

PCB material batch tracking

Material Batch Tracking

Material lots can be associated with agreed manufacturing and inspection records.

PCBA component lot tracking

Component Lot Tracking

Component records follow the sourcing model and agreed traceability requirements.

PCB inspection records

Inspection Records

Inspection and test reports can be maintained according to agreed documentation scope.

PCB corrective action support

Corrective Action Support

Manufacturing and inspection data supports project-specific corrective-action review.

IPC Standards & Acceptance Class

IPC Class 2 is commonly specified for general industrial and commercial products. IPC Class 3 may be specified for products requiring higher reliability and more demanding acceptance criteria.

The required acceptance class must be confirmed before quotation and production because it may affect design rules, inspection, documentation, yield and cost.

PCB Certifications & Compliance

The published ISO 9001 and ISO 14001 certificates name Zhongshan Wenquan Electronic Manufacturing Co., Ltd. for PCBA processing. They do not certify every manufacturing location or product. Read the holder, facility, validity and scope on the certifications page.
