Parylene Removal Services

Specialist Rework for the Toughest Conformal Coating

Parylene removal services require both expertise and specialised equipment.

Unlike liquid conformal coatings, Parylene cannot simply be chemically stripped. Therefore, SCH provides precision micro-abrasion rework, enabling technicians to selectively and safely remove Parylene while protecting the underlying PCB, pads, and component leads. After removal, assemblies can then be repaired, modified, and re-coated under strictly controlled conditions at our UK facility, ensuring consistent quality and long-term reliability.

Our services support aerospace, medical, defence, and industrial electronics where reliability and quality are critical.

When Parylene Removal Is Required

  • Component replacement or circuit modification on coated boards
  • Correction of defects discovered after coating and test
  • Failure analysis and root cause investigations
  • Refurbishment, life-extension, or product upgrade programmes

How We Remove Parylene

SCH utilises advanced micro-abrasion systems (such as the Vaniman Problast) with fine, carefully controlled abrasive media. As a result, this method delivers precise and selective removal without causing damage to fine-pitch components or sensitive board areas.

In practice, the process allows:

  • Selective pad, lead, and trace exposure for effective rework
  • Tight control of pressure, nozzle size, and media flow for accuracy
  • Repeatable and documented process parameters for consistency and traceability

Because Parylene offers extremely high chemical resistance, it cannot be removed using wet chemical stripping. Therefore, micro-abrasion remains the only viable and controlled method for safe and effective Parylene removal.

Our Parylene Rework Workflow

  1. Assessment & quotation – review of BOM/photos or sample assemblies
  2. Incoming inspection – documentation, cleanliness, baseline photos
  3. Precision removal – micro-abrasion under magnification
  4. Cleaning & drying – ionic contamination check, bake dry if required
  5. Repair/rework – component replacement, soldering, modifications
  6. Re-coating – reapply Parylene in controlled vacuum deposition
  7. Final inspection & reporting – visual, magnified, and optional electrical test with documentation

Quality & Compliance

  • All rework aligned with IPC-A-610 criteria
  • Process traceability with photos and batch records
  • Optional Certificates of Conformance (CoC) and First Article Inspection (FAI) reports

In-House vs Outsourced Parylene Removal

Not every facility has the equipment or expertise to remove Parylene. SCH provides both options:

  • Outsourced service: send us your boards for expert removal and re-coating.
  • In-house option: we supply Vaniman micro-abrasion systems and training if you prefer to manage rework internally.

FAQs

Can Parylene be chemically stripped?
No. Parylene is chemically resistant. Only micro-abrasion can selectively remove it.

Can you recoat after removal?
Yes. We remove, repair, and then reapply a compatible conformal coating in line with the IPC repair standards.

Is selective removal possible?
Yes. Micro-abrasion allows exposure of just one pad or connector without disturbing the rest of the board.
