Coating Removal Methods

Solvent stripping and micro-abrasion are the primary conformal coating removal techniques often referenced within the coating removal and rework hub, which have proven effective. Solvents soften acrylics and urethanes for controlled cleaning, while micro-abrasion enables precise local removal on sensitive areas without PCB damage.

Removal & Rework: Precision Micro-Abrasion

Parylene is not solvent-removable; precision micro-abrasion with carefully selected media (e.g., aluminium oxide or sodium bicarbonate) provides controlled access for solder repair and modification. This method is discussed extensively in the rework hub.

Rework Workflow

Follow a validated sequence: identify the defect, remove coating locally or fully, complete repair, clean and verify, then re-coat to restore protection and documentation traceability, as outlined in our comprehensive conformal coating rework sources.

Removal & Rework Hub: Local vs Full Stripping

Choose localised removal to minimize risk and time for targeted fixes. Opt for full stripping when failures are widespread, coatings are incompatible, or a full redesign is required, information thoroughly covered in our rework hub.
