Description
Printed Circuit Board Assembly: Prepare an Assembly-Only Enquiry
Use this page when you already have bare boards or need to separate assembly responsibilities from fabrication. Identify board supply, component supply and required checks before comparing quotations.
Describe the supplied boards
Provide board revision, dimensions, panel drawing and the number of usable boards delivered for assembly. Include the surface finish, storage history where relevant, and any handling requirements. State who is responsible for board defects, shortages and replacement material before scheduling the build.
Describe supplied components
Send a BOM with manufacturer part numbers and reference designators. Identify consigned, turnkey and do-not-populate lines. For supplied parts, record packaging, quantity and handling instructions. Explain how shortages or damaged packaging should be resolved rather than assuming every BOM line arrives ready for placement.
Prepare placement and assembly information
Supply coordinate data with an identified origin, units and rotation convention. Include top and bottom assembly drawings, polarity marks and any manual operations. A photograph can clarify an unusual feature, but it should not replace the controlled placement and assembly data.
Agree inspection and test coverage
Describe the expected checks and required reporting. Hidden joints may need a different inspection route from exposed solder joints. Programming and powered functional checks need their own instructions, fixtures and acceptance conditions. Specify the required standard and class for the agreed work; do not infer certification from a standards name.
Compare and release
Ask for setup, recurring assembly, special handling and test costs to be distinguished. State the batch quantity and target delivery. Keep the approved BOM, board revision and assembly instructions together before release. The amount shown by a generic catalogue listing does not establish the price of the proposed assembly.
Prepare the assembly file package. For the supplier evidence needed for your order, review quality assurance.
