Conformal Coating Removal Services

When assemblies need modification, repair, or failure analysis, professional conformal coating removal services prevent damage and minimise scrap. SCH delivers controlled removal using wet stripping and micro-abrasion methods to safely expose pads, leads, and traces—ready for rework and recoat.

We handle acrylic, urethane, silicone, UV cure and epoxy conformal coatings across aerospace, defence, medical, automotive, and industrial electronics.

When Removal Services Make Sense

• Component replacement or circuit modification on populated PCBs
• Defect correction after inspection (bubbles, fisheyes, pooling)
• Refurbishment/upgrades of high-value assemblies
• Failure analysis and reliability investigations

Removal Methods We Use

Wet Stripping (Bulk Removal)

Chemically formulated baths remove most liquid conformal coatings efficiently for batch refurbishment and recoat workflows.

• Ideal for acrylics, many urethanes and silicones (check chemistry)
• Process-controlled immersion with operator safety measures
• Consistent, high-throughput results for production batches

Micro-Abrasion (Selective, Precision Removal)

Micro-abrasive blasting (e.g., Vaniman Problast) enables pinpoint exposure of pads, leads, and traces without damaging adjacent features.

• Perfect for localised rework on dense PCBs and fine-pitch parts
• Removes hard coatings like UV cure conformal coatings
• Tight control of media and pressure for repeatability
• Complements wet stripping for hybrid jobs

Supported Coatings & Typical Substrates

• Coatings: Acrylic (AR), Urethane (UR), Silicone (SR), Epoxy (ER)
• Substrates: FR-4 PCBs, mixed-metal assemblies, connectors, harness areas

Note: Parylene is not chemically wet-strippable. For Parylene, see our dedicated micro-abrasion service page.

How Our Removal Service Works

1. Feasibility & quotation — BOM/photos or sample review to select method(s).
2. Incoming inspection — baseline images, masking assessment, cleanliness checks.
3. Controlled removal — wet stripping and/or micro-abrasion per process plan.
4. Clean & dry — thorough rinse/neutralise (where applicable), bake dry.
5. Inspection & testing — visual & magnified checks; optional electrical tests.
6. Recoat (optional) — re-mask, reapply coating to target window, cure, final inspect.
7. Documentation — photos, batch records; thickness verification on coupons where required.

Quality, Traceability & Standards

• Processes aligned with IPC-A-610 acceptability criteria
• Thickness checks by approved methods (representative flat areas/coupons)
• Photographic evidence, batch records, and optional CoC/FAI reports

Conformal Coating Removal Training

Removal and rework is unavoidable—do them safely, cleanly, and repeatably. SCH delivers hands-on training for both
micro-abrasive blasting (Vaniman Problast) and wet stripping (WS100), covering setup, media/chemistry selection, ESD protection, operator technique, and process validation.

• Selective Parylene & liquid coating removal without substrate damage
• ESD-safe workflows, fume control, PPE, and H&S compliance
• Media selection & pressure control (Problast)
• • Tank sequence & chemistry control (WS100)
• Defect prevention, cleanliness checks, and pass/fail criteria aligned to IPC
• SOPs, checklists, and traceable documentation for audits

This module can be delivered standalone or as part of a complete Conformal Coating Training Programme, tailored to your products, equipment, and quality objectives.

FAQs

Can you remove coating from just one area?
Yes. Selective micro-abrasion exposes only the required pads/leads while protecting surrounding features.

How do you verify the board is ready to recoat?
Cleanliness checks, visual/magnified inspection, and thickness verification on coupons or representative areas.

Turnaround time?
Depends on volume and complexity; we offer expedited options for urgent rework.
