Data Confidentiality
Discuss an NDA and define how drawings, BOM data, and production files may be used before sharing controlled information.
PROJECT-SPECIFIC REVIEW
SMT assembly is reviewed as a complete process window
An SMT review connects land patterns, package types, paste, stencil design, placement, reflow, inspection, and handling. A machine model or nominal placement specification alone does not establish project capability.
Inputs required for review
- Board revision, panel drawing, fiducials, and support requirements
- Centroid data and BOM with package and polarity information
- Moisture sensitivity, bake, storage, and traceability requirements
- Inspection criteria, X-ray needs, test access, and rework limits
Conditions and limitations
Minimum package size, fine-pitch geometry, board handling, placement accuracy, reflow atmosphere, and inspection method remain subject to data review and the agreed acceptance standard.
Evidence and next step
The controlled quotation should identify the reviewed revision, included operations, exclusions, acceptance evidence, responsibilities, and release conditions.
Release an assembly-ready data set
| Work area | Inputs or responsibility | Expected output |
|---|---|---|
| Package | Approved ordering code and package drawing | Confirm footprint, polarity and handling restrictions |
| Panel | Rails, fiducials, underside components and support | Resolve support and handling conflicts |
| Placement | Units, origin, side and rotation convention | Check a known component independently |
| Process | Alloy, thermal restrictions and moisture handling | Agree conditions before material is exposed |
| Acceptance | Observable joints, hidden joints and functional requirements | Separate inspection evidence from behavior tests |
Use the assembly file checklist to prepare the discussion. Unknown inputs should be listed as open questions; they do not authorize substitutions, omitted tests or unrecorded design changes.
Resolve the three assembly input gaps before a production review
Start with the revision you intend to build and mark any missing record openly. The first enquiry can describe the product, quantity, board revision, supply model and the question to resolve; a complete engineering release packet follows when those facts are available.
| If this is missing | Send or confirm | Use this preparation guide | What remains open |
|---|---|---|---|
| Panel and support definition | Panel drawing, single-board outline, conveyor direction, rail and fiducial plan, both-side component projections and intended separation method. | Panel support and rail sign-off | Actual clamp and support clearance, board-position traceability and post-separation acceptance require a process trial. |
| Package-to-file agreement | Full manufacturer part number, package drawing revision, approved BOM, PCB copper/mask/paste outputs, stencil revision and centroid convention. | Package, footprint, stencil and placement cross-check | Unmatched library names, exposed-pad nets or rotation conventions must be resolved before assembly release. |
| Moisture-sensitive material history | Component labels, lot and package IDs, bag condition, opening and storage log, any split/return record and approved handling procedure. | Opened-reel and return history example | Missing exposure periods or unknown storage conditions require disposition; a reseal does not restore an unknown history. |
For a project review request, identify which records are ready and which decisions are still open. The quotation and agreed build plan should state the included assembly, inspection, test and material responsibilities. No example table on this page is a claim that a particular package, fixture or inspection method has been approved for your product.

These company-document references and licensed process illustrations support engineering discussion. They do not prove current ownership, condition, availability, accuracy, capacity, or project suitability; routing and allocation are confirmed for each project.
Line type, equipment allocation, staffing, reflow profile, inspection, and test scope are confirmed for each project after the manufacturing data has been reviewed.

PCB Fabrication Parameters and Assembly Interfaces
Bare-board layer count, copper weight, and via structure do not replace checks for SMT packages, panelization, and soldering. Materials, process combinations, and production-site allocation are reviewed against the manufacturing data.
