PCB RFQ Checklist
for Manufacturing
A practical framework for preparing complete, quote-ready PCB and PCBA manufacturing RFQs.
Learn what engineering, procurement and quality teams should define before requesting PCB fabrication or assembly quotations, how to make supplier quotations comparable, and which RFQ gaps can create cost, quality and delivery problems later.
What Is a PCB RFQ Checklist?
The checklist is important because a PCB quotation is rarely determined by board geometry alone. Material, layer count, copper weight, board thickness, surface finish, component sourcing, assembly complexity, testing, quantity, lead time and commercial scope can all affect the quotation.
A good RFQ therefore does more than transfer files to a supplier. It establishes the scope against which the supplier is expected to quote.
This distinction becomes particularly important when several suppliers are being evaluated. If each supplier makes different assumptions, the resulting quotations may appear different even when the underlying manufacturing requirement is supposed to be the same.
For procurement teams, the objective is therefore not simply to obtain a price. It is to create a quotation package that supports a controlled technical and commercial comparison.
Why a Complete PCB RFQ Matters
A supplier cannot quote what has not been defined.
When an RFQ contains incomplete technical information, suppliers compensate by making assumptions or returning clarification questions. Different suppliers can then interpret the same requirement differently.
That creates a common procurement problem: several quotations are received, but the procurement team cannot confidently determine whether they are actually quoting the same scope.
Operational problems caused by weak RFQs
- Repeated supplier clarification cycles
- Multiple quotation revisions
- Different material assumptions
- Unclear testing responsibilities
- Unexpected NRE or tooling charges
- Component substitution disputes
- Incorrect lead-time assumptions
- Different packaging or logistics assumptions
- Commercial comparison based only on unit price
- Cost changes after technical review
A structured RFQ also creates a better foundation for vendor evaluation , supplier qualification and subsequent procurement negotiations.
What Information Does a PCB Supplier Need?
The exact RFQ package depends on whether the requirement is bare PCB fabrication, PCB assembly, turnkey PCBA or a more complete electronics manufacturing requirement.
The following categories provide a practical starting point.
| Category | Typical Information |
|---|---|
| Project | Part number, project name, revision, application, prototype or production status, quantity and required delivery. |
| PCB Fabrication | Gerber or equivalent manufacturing data, drill files, board dimensions, layer count, thickness, copper weight, material and surface finish. |
| PCB Stack-up | Layer construction, dielectric requirements, controlled impedance requirements and applicable fabrication constraints. |
| Assembly | BOM, manufacturer part numbers, placement data, assembly drawing, SMT/THT requirements and special assembly instructions. |
| Testing | AOI, X-ray, ICT, flying probe, functional test, programming, test fixtures and test documentation. |
| Quality | IPC requirements, inspection criteria, traceability, certificates and customer-specific quality requirements. |
| Commercial | Prototype and production quantities, annual demand, NRE, tooling, stencil, component sourcing model, payment terms and Incoterms. |
| Delivery | Required date, shipment destination, packaging, ESD protection, labelling and partial shipment requirements. |
PCB RFQ Checklist
For bare PCB fabrication, the supplier needs enough information to understand the board construction, manufacturing complexity and commercial quantity.
| RFQ Item | What to Define |
|---|---|
| Part Number & Revision | Clearly identify the board and the revision being quoted. |
| Gerber / Manufacturing Data | Provide the controlled manufacturing data required to fabricate the board. |
| Drill Data | Include the applicable NC drill information and associated hole requirements. |
| Layer Count | Define the number of conductive layers. |
| Board Thickness | State finished board thickness and applicable tolerance. |
| Copper Weight | Define copper requirements for the relevant layers. |
| Material | Define the required laminate or applicable material specification. |
| Surface Finish | Specify the required surface finish. |
| Solder Mask | Define solder mask requirements where applicable. |
| Impedance | Identify controlled impedance requirements and applicable target values/tolerances. |
| Quantity | Provide prototype, pilot and production quantities where available. |
| Delivery | State required manufacturing lead time and delivery destination. |

PCBA RFQ Checklist
A PCBA RFQ introduces another layer of complexity because the supplier is no longer quoting only board fabrication. Component procurement, assembly processes, programming, inspection and testing may all form part of the requirement.
BOM requirements
- Reference designators
- Component descriptions
- Manufacturer names
- Manufacturer part numbers
- Quantity per assembly
- Approved alternate components
- DNP components
- Customer-supplied components
- Sourcing restrictions
Assembly requirements
- Centroid / CPL / pick-and-place data
- Assembly drawings
- SMT requirements
- THT requirements
- Manual assembly operations
- Special soldering requirements
- Programming requirements
- Conformal coating where applicable
- Special handling requirements
Manufyn also maintains a dedicated PCB Assembly & Final Enclosure Manufacturing resource for broader electronics manufacturing requirements.
Revision Control in a PCB RFQ
Revision control is one of the easiest RFQ areas to overlook and one of the most disruptive when handled incorrectly.
A PCB assembly package can contain several related files: Gerbers, BOM, centroid data, assembly drawings, schematics, test documentation and programming information.
These files need to describe the same intended product revision.
RFQ revision-control checks
- Part number is consistent across documents.
- Revision is clearly identified.
- BOM revision matches the intended assembly.
- Gerber data corresponds to the quoted revision.
- Centroid data corresponds to the assembly revision.
- Assembly drawings are controlled.
- Test documentation identifies the applicable version.
- Superseded files are removed or clearly identified.
Quality and Testing Requirements
Quality requirements should be visible before suppliers submit their quotations.
Otherwise, one supplier may include additional inspection or testing while another excludes it from the quotation.
Potential PCB requirements
- PCB workmanship requirements
- IPC class requirements
- Dimensional inspection
- Electrical testing
- Material certification
- Certificate of Conformance
- Traceability
Potential PCBA requirements
- AOI
- X-ray inspection
- ICT
- Flying probe testing
- Functional testing
- Programming verification
- First article inspection
- Test reports
- Lot traceability
Where required, quality requirements should be linked to the actual product risk rather than added as generic paperwork.

Commercial Requirements to Include in a PCB RFQ
A technical package alone does not create a complete commercial RFQ.
Procurement teams should also define the commercial assumptions against which suppliers are expected to quote.
| Commercial Area | Questions to Define |
|---|---|
| Quantity | What is the prototype quantity? Pilot quantity? Production quantity? Annual demand? |
| Quantity Breaks | Should the supplier quote multiple volume levels? |
| NRE | Are engineering, setup or other non-recurring charges applicable? |
| Stencil | Is stencil cost included or separate? |
| Fixtures | Are test or programming fixtures required? |
| Component Sourcing | Is the build turnkey, partial turnkey or consignment? |
| Logistics | Who is responsible for freight, packaging and delivery? |
| Payment | What payment terms should suppliers quote against? |
| Incoterms | What delivery term applies to the quotation? |
For international procurement, review the Incoterms 2020 Guide before comparing landed commercial costs.
How to Compare PCB Supplier Quotations
The lowest unit price does not automatically represent the lowest comparable manufacturing cost.
Before comparing suppliers, procurement should normalize the quotation scope.
Compare the same commercial elements
- PCB fabrication
- Components
- Assembly
- Stencil
- NRE
- Fixtures
- Programming
- Inspection
- Testing
- Packaging
- Freight
- Lead time
- Payment terms
- Minimum order quantities
- Supplier exclusions
This is where an RFQ checklist connects directly with broader manufacturing procurement disciplines such as vendor evaluation , manufacturing cost negotiation and supplier risk management .
Common PCB RFQ Mistakes to Avoid
1. Sending only a board image
A visual representation of a PCB is not a controlled manufacturing package.
2. Assuming Gerbers define everything
Manufacturing data may define board geometry without defining every commercial, quality, material and delivery requirement.
3. Providing a generic BOM
Generic descriptions can create sourcing ambiguity. Where appropriate, identify manufacturer part numbers and approved alternatives.
4. Allowing uncontrolled substitutions
If component substitutions are permitted, the RFQ should establish how alternatives will be evaluated and approved.
5. Mixing document revisions
Suppliers should not have to determine which engineering document takes precedence.
6. Leaving testing undefined
Testing can affect equipment, fixtures, programming, labour and lead time.
7. Comparing quotations without normalizing scope
A supplier that excludes testing or component procurement may appear cheaper than a supplier quoting a complete scope.
8. Ignoring production volume
Prototype, pilot and production requirements can involve different commercial and manufacturing assumptions.
A Practical PCB RFQ Workflow
A useful RFQ process can be organized into the following sequence.
Define the Requirement
Identify the product, board, part number, revision, quantities and intended manufacturing stage.
Collect Engineering Data
Assemble Gerbers, drill files, BOM, centroid data, drawings, stack-up information and other applicable files.
Check Revision Consistency
Verify that all documents correspond to the intended product revision.
Define Quality and Testing
Establish inspection, testing, traceability and documentation requirements before supplier quotation.
Define Commercial Scope
Clarify quantities, NRE, tooling, component sourcing, packaging, logistics and payment assumptions.
Release the RFQ
Send the same controlled RFQ package and quotation instructions to each supplier being evaluated.
Normalize Supplier Quotes
Separate technical compliance, price, exclusions, lead time, NRE, testing and other commercial assumptions.
Evaluate the Supplier
Combine commercial comparison with technical, quality, capacity and supplier-risk evaluation.
Is Your PCB RFQ Ready to Release?
Before sending the RFQ to suppliers, procurement and engineering teams should be able to answer the following questions.
- Is the exact PCB or PCBA part number defined?
- Is the revision clearly controlled?
- Are the manufacturing files complete?
- Are material and board construction requirements defined?
- Is the BOM sufficiently detailed for procurement?
- Is component sourcing responsibility clear?
- Are testing and inspection requirements defined?
- Are prototype and production quantities identified?
- Are NRE, stencil and fixture requirements clear?
- Are packaging and logistics requirements defined?
- Will every supplier receive the same information?
- Can the quotations be normalized after receipt?

From RFQ Data to Supplier Qualification
An RFQ is only one stage of the manufacturing procurement process. Once quotations are received, companies may need supplier qualification, factory assessment, quality inspection and commercial evaluation before releasing production.
Manufyn’s broader manufacturing resources cover these stages, including Factory Audit , Supplier Selection and Quality Inspection .
For electronics manufacturing specifically, the Box Build Supplier Qualification resource provides another useful reference when the PCB or PCBA requirement forms part of a larger electronics assembly.
Manufyn also publishes manufacturing case studies covering supplier audits, manufacturing development, prototyping and production-related work.
