Conformal Coating Removal & Rework Hub

This conformal coating removal and rework hub brings together practical guides on stripping and repairing coatings. Learn where to apply solvent removal, when to use precision micro-abrasion, and how to run reliable Parylene rework—while keeping PCB quality and traceability intact.

Coating Removal Methods

Use solvent stripping for compatible liquid coatings (e.g., acrylics, some urethanes) where you can soften and lift the film for controlled cleaning. Choose precision micro-abrasion when you need local access on sensitive areas—expose test points or connector rows without damaging the PCB.

Inside the Micro-Abrasive Blasting Process

Go beyond “when to use” and learn how micro-abrasion works. This deep dive explains media selection (including VanAcrylic), air pressure and flow, nozzle geometry, standoff and angle, plus ESD-safe technique for reliable pad exposure and minimal risk to solder mask.

Removal & Rework: Precision Micro-Abrasion

Parylene does not dissolve in standard solvents. A tuned micro-abrasive blasting recipe—media selection, pressure, nozzle, and angle—gives controlled access for solder repair and modification while protecting pads, solder mask, and component bodies.

Rework Workflow

Run a validated sequence: confirm the defect, remove coating locally or fully, complete the electrical/mechanical repair, clean and verify, then re-coat to restore protection and documentation traceability.

Local vs Full Stripping

Choose localised removal to minimise time and risk when you only need targeted access. Move to full stripping when failures are widespread, coatings are incompatible with the next process, or redesign demands a clean start.
