PCB Quality Agreement Checklist for Fabrication and PCBA

This PCB quality agreement checklist defines how a customer and PCB/PCBA supplier control specifications, acceptance, traceability, changes, nonconformance and performance. The agreement supplements the drawing, purchase order and commercial contract by assigning who must do what, which records prove it, and when customer approval is required.

This checklist is for engineering, supplier quality and purchasing teams preparing a new supplier, new product or higher-risk production program. It is not legal advice; liability, warranty, confidentiality, governing law and other legal terms should be reviewed by qualified counsel.

The 12 PCB Quality Agreement Clauses to Set Before a PO

Define Scope, Sites and Responsibility Owners

Name the legal entities, manufacturing sites, product families, bare PCB/PCBA scope, component sourcing, testing, packaging and any special process. Identify engineering, quality, purchasing and account contacts plus an escalation path. If different factories or subcontractors perform parts of the work, state who remains accountable for the finished result.

Set the Document Hierarchy and Design Authority

List the controlled inputs: purchase order, Gerber/ODB++ or IPC-2581, drill data, fabrication drawing, stackup, BOM, CPL, assembly drawing, test specification and approved engineering queries. Define which record wins when they conflict and how both parties confirm the released revision.

The supplier may propose manufacturability changes, but design authority must be explicit. Use the PCB engineering change order checklist when an approved design changes after release.

Agree on Materials, Sources and Sub-Tier Processes

Define approved laminate/material families, copper, finish, solder mask, components and any customer-controlled sources. State substitution rules, counterfeit/traceability expectations, storage/shelf-life controls and customer-supplied material responsibilities. Require control of outside finish, special processes, bare-board sources or test labs that can affect acceptance.

Write Inspection, Test and Shipment Acceptance Rules

A quality agreement should name applicable specifications, drawing requirements, sample or 100% checks, test methods, acceptance limits, required reports and shipment-release authority. Separate bare-board electrical/visual/dimensional evidence from PCBA AOI/X-ray/ICT/functional evidence. Do not use “standard inspection” when the buyer expects a specific record.

The PCB testing guide helps choose evidence matched to the build and risk.

Specify Traceability Depth, Record Retention and Retrieval

Choose shipment, lot, panel or unit traceability based on risk and customer need. Define links to material/component lots, manufacturing order, revision, process/inspection/test records, rework and shipment. State retention period, format, access, backup and expected retrieval time. Avoid promising unit-level history if the agreed process only controls lots.

Control Supplier Changes, Deviations and Nonconformance

List material, process, site, equipment, subcontractor, design/configuration and supply-status changes that require notice and approval. The PCB supplier change notification checklist provides the PCN fields and effectivity gates.

Separately define temporary deviations and nonconforming product: containment, segregation, customer notification, material-review authority, use-as-is/rework/scrap/return decisions and traceability. The supplier should never treat shipment pressure as approval.

Define Complaint, CAPA and Effectiveness Requirements

Set who acknowledges a complaint, contains affected lots, provides interim status and submits root-cause/corrective-action evidence. Do not measure closure only by report date. Require verification that the cause was removed, related products/processes were reviewed and later production confirms effectiveness. Define how repeat or major issues escalate.

Set Audit Rights, Confidentiality and Record Access

Define planned and cause-based audit rights, notice, sites/processes in scope, remote/on-site access, customer/end-customer participation, confidentiality and corrective-action follow-up. Audit access should respect sensitive supplier information while still proving control. Use the PCB supplier audit checklist to connect clauses with evidence sampling.

Measure Supplier Performance and Escalation

Agree on a small set of defined metrics: accepted/defective quantity, escapes/returns, delivery, response time, CAPA aging and repeat findings. Define data source, calculation period, review frequency and escalation thresholds. A scorecard should trigger decisions—improvement plan, controlled new business, re-audit or disqualification—not exist as decoration.

Plan Business Continuity, Obsolescence and Supplier Exit

Address disaster recovery, capacity interruption, material/component obsolescence, EOL notice, last-time buy, customer-owned inventory/tooling, unfinished WIP and controlled transfer to another site or supplier. Define what records and approved data must be returned or transferred at termination. Legal ownership and liability terms belong with qualified contract review.

What to Send EBest Circuit Before Finalizing the Quality Scope

Use this PCB quality agreement checklist when sending the PCB/PCBA part and revision, released manufacturing files, application/risk context, quantity, acceptance criteria, test/report needs, traceability depth, record requirements, change-notification rules and target delivery. For assembly, include BOM/CPL, source restrictions, programming and functional-test inputs.

EBest Circuit can review the manufacturable quality scope and quotation assumptions for the project. The final agreement should identify what is feasible, which evidence will be delivered and which customer approvals remain required.

FAQ About PCB Quality Agreements

What is a PCB quality agreement?

It is an operational agreement assigning customer and supplier responsibilities for specifications, acceptance, traceability, changes, nonconformance, records and performance.

Is a quality agreement the same as a purchase order?

No. The PO places the order; the quality agreement defines continuing quality responsibilities and evidence.

Who should approve it?

Engineering, quality and purchasing should approve their responsibilities; legal counsel should review legal/commercial terms where appropriate.

Should prototypes need the same agreement as production?

Not always. Scale controls to risk, but even prototypes need clear files, acceptance, change authority and nonconformance handling.

What traceability level should be required?

Select shipment, lot, panel or unit depth from product risk and customer/regulatory needs, then confirm the supplier can execute it.

How are supplier changes controlled?

Define PCN triggers, notice, evidence, customer approval and the first affected lot/date/PO boundary.

What happens when quality performance declines?

Use agreed metrics and escalation: containment, corrective action, improvement plan, re-audit, restricted business or disqualification.
