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 (silicone-free paper masking where contamination control matters), Parylene deposition and selective solder protection.

SCH conformal coating masking solutions including Molex masking boots, pre-cut masking shapes, and reusable connector boots fitted to a PCB

SCH masking solutions used in real production: pre-cut masking shapes, Molex masking boots, and reusable connector boots on PCB assemblies.

Our Conformal Coating Masking Product Range

Custom Masking Boots

  • Reusable and precision-fitted to individual components
  • Replace tapes and dots in high-volume production
  • Deliver repeatable masking with reduced labour input

Reusable masking boots do more than reduce masking time. They improve seal repeatability, reduce operator dependency and lower total masking cost when service life is considered.

Molex Connector Masking Boots: Prevent coating ingress into connector contacts and mating faces.

Pre-Cut Masking Shapes

  • Supplied on sheets for fast, accurate application
  • Available in silicone-free paper constructions for liquid conformal coating applications, with polyimide custom-cut sheets also available where process requirements demand them
  • Eliminate manual cutting of masking tape
  • Improve consistency while reducing waste and rework

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.

Where contamination control is important, training can also cover the correct use of silicone-free paper masking materials and how masking material selection affects coating quality.
