Conformal Coating & Parylene Masking Solutions

Used Daily in Our Own Coating Services

SCH Technologies supplies a complete range of conformal coating masking materials, purpose-selected to protect critical PCB areas and maintain process control.

All masking solutions we supply are used daily within our own conformal coating services, giving customers confidence in clean removal, precise coverage, and repeatable performance in real production environments.

From reusable custom boots (including connector masking boots) to controlled masking tapes, dots, and pre-cut shapes, SCH masking solutions are designed to support both high-volume manufacturing and specialised PCB applications including liquid conformal coating, polyimide-based masking where appropriate, Parylene deposition, and selective solder protection.

Masking Dots

  • Fast, repeatable masking for vias, pads, and grounding holes
  • Consistent edges to minimise coating bleed
  • Reliable clean removal after coating and cure
  • Available in paper-based and polyimide (Kapton®-type) constructions where required

See Masking Dots Range →

Note on polyimide masking materials: Some masking tapes, dots, and shapes are manufactured from polyimide film and are commonly referred to in industry as “Kapton®-type” materials. Kapton® is a registered trademark of DuPont. SCH supplies polyimide masking materials selected for performance in coating and soldering processes and does not claim supply or endorsement by DuPont unless explicitly stated.

Conformal Coating Masking Training

Masking is one of the most labour-intensive and defect-sensitive stages of conformal coating.

SCH delivers hands-on masking training covering tapes, dots, shapes, and boots, focused on speed, repeatability, and defect prevention.

Training can be delivered standalone or as part of a complete conformal coating programme, aligned with IPC expectations and real production practice.
