PCB Surface Treatment
Choose the PCB finish with the component packages, storage and soldering process in mind. Finish availability and performance depend on the specified construction and process; the final selection belongs in the released fabrication notes.
Requirements for an engineering review
| Topic | Information to supply | Decision to confirm |
|---|---|---|
| Assembly fit | Fine-pitch or bottom-terminated packages, soldering and rework requirements. | Review surface geometry and process compatibility. |
| Product conditions | Contact surfaces, storage, handling and expected service environment. | Use the relevant material and finish requirements. |
| Fabrication specification | Selected finish, coverage and applicable acceptance conditions. | Resolve any alternate finish before production. |
| Release evidence | Board drawing, inspection and customer approval. | Keep the finish decision consistent across the drawing and order. |
How to confirm the applicable range
Send the current revision and the limits that matter to your product. The review should identify the responsible manufacturing site or supply partner, the agreed conditions and the approval needed for exceptions. Keep the confirmed range, source and review date with the released project records.
Release checklist
- Resolve conflicting notes or units before the order is released.
- Confirm whether the requirement is routine, requires an engineering trial or is outside the proposed scope.
- Agree inspection or verification evidence and the owner of unresolved design decisions.
