Published typical prototype lead times; the confirmed schedule depends on files, parts availability, quantity and test scope and is stated in the quotation.
Low volume PCB assembly: decisions before release
Name the first-article approver and agree what they review.
Decide how open issues affect release of the remaining batch.
| Action before release | Details to agree |
|---|---|
| Send the BOM with approved alternates | Parts and substitution approvalList exact parts, do-not-fit items, approved alternatives and the person who approves changes. State whether an exception applies only to this order or changes the design. |
| Name who approves the first article | Who approves releaseAgree the review point, assemblies to review, required evidence and an approval contact with a backup. Define how unresolved issues affect release of the remaining batch. |
| Match the file revisions | Files, test and acceptanceList the released board files, drawings, BOM and placement data. Include test coverage, firmware, pass/fail criteria and report needs; ask the supplier to confirm the revision received. |
| Flag missing parts and unused material | Purchasing and ownershipIdentify open BOM items, the purchasing owner and which boards can be assembled with the parts available. Agree ownership and handling of unused purchased or customer-supplied components. |
| Set shipment quantities and destinations | Request split shipmentsRequest the quantity split, destination, packaging and proposed schedule for each shipment. Name who approves each release and how remaining work is recorded. |
| Review changes before a repeat order | Repeat order with a changed designSend the current manifest, changes since the previous build, barcode references and remaining-material plan. Recheck availability, inspection needs and first-article review. |
Use the RFQ checklist and editable release manifest — a list of files and versions approved for your build.
Inspection and traceability for your batch
At the Shenzhen PCBA factory, every applicable SMT board goes through 3D SPI and 3D AOI, small batches included. Agree X-ray and ICT coverage for your design. The Shenzhen PCBA factory has 9 3D SPI units, 5 3D AOI units, one X-ray unit and one ICT unit.
X-ray: UNICOMP AX8200 · ICT: TRI TR5001E.
01005 imperial placement is in stable volume production, with 10 sets of original YAMAHA 4 mm-tape feeders.. MES supports unique-barcode traceability, material mis-load protection (scanning checks that the right reel is loaded) and smart storage linked to FIFO.
