Control material purchasing and substitutions
Material procurement starts with an approved BOM and a clear authority for changes. A suggested alternate is not permission to buy or fit it.
| BOM decision | Customer input | Purchasing handover |
|---|---|---|
| Source selection | Manufacturer part number, acceptable sources and lifecycle constraints. | Proposed source, availability, purchasing assumptions and traceability requirements. |
| Substitution | Electrical, mechanical, firmware and qualification restrictions. | Engineering comparison and written customer approval before a substitute is released. |
| Inventory ownership | Forecast, order releases and customer-supplied lines. | Shortage, excess / obsolete material, attrition and cancellation terms agreed for the project. |
Handover and acceptance
Deliver an approved purchasing BOM, open-material issues and the agreed ownership of remaining stock. Enclosures, cable assemblies and other sourced items require their own drawings and acceptance criteria; confirm the supplier and assembly responsibilities.
Prepare the BOM before component procurement
Identify the board revision, assembly variant and BOM revision together. For each reference designator, state whether the part is fitted or DNP, its quantity per board, the approved manufacturer part number and who supplies it.
A missing part number is an open question, not a no-fit instruction. Confirm how your CAD export represents DNP parts, then reconcile the BOM with the placement file and assembly drawing before the production release.
Use the BOM, DNP and revision checklist to prepare a release worksheet. If a part changes, follow the component substitution approval steps. For quantities and the rest of the quote package, use the PCBA RFQ checklist.
Is there a minimum order quantity (MOQ) for product orders?
Minimum quantity and batch economics depend on the BOM, setup, testing and sourcing scope. Discuss your planned quantities with sales.
What is your testing policy and how you control the quality?
Agree the inspection and test plan for your product. Depending on the design and executing site, this may include PCB electrical checks, AOI, BGA X-ray inspection, first-article review and customer-defined functional testing. Confirm coverage and acceptance limits in the quotation.
What service do you have?
We can offer OEM service including PCBA making, PCB assembly, components sourcing. Additionally, we can also provide programming, testing, cables, enclosure assembly service.
Do you support quick proofing?
Confirm prototype timing after design review, material availability and the test plan have been checked.
Are my files safe?
Agree confidentiality terms, access permissions and the file-transfer channel with sales before sharing design files. Identify any approved partner access in the project agreement.
If we have order production needs, how can we contact you?
Request a PCBA Quote with your project stage, quantities, delivery country and test requirements. Sales will coordinate the next steps and file transfer.
