Conformal Coating & Parylene Masking Solutions

Production-Proven Masking Materials Used Daily in SCH Coating Services

All masking materials supplied by SCH are used daily within our own conformal coating and Parylene coating services.

Rather than supplying generic masking products, we select tapes, dots, shapes and reusable boots that have proven reliable in real production environments.

This helps improve masking consistency, reduce rework and support controlled coating processes.

Conformal coating masking solutions infographic showing masking boots for connectors, masking dots for vias, masking tape for PCB edges and masking shapes for complex geometries.

Different masking methods suit different PCB geometries. Masking boots protect connectors, masking dots cover vias and pads, masking tape controls edges, and masking shapes support complex areas to improve process consistency and reduce coating defects.

Choosing the Right Masking Method

Effective masking starts with understanding the geometry being protected. Different masking materials solve different problems and selecting the correct approach often has a greater impact on quality than the masking material itself.

  • Grounding holes, vias and pads โ†’ masking dots
  • PCB edges and linear keep-out areas โ†’ masking tapes

Masking Solutions Used in SCH Production

Custom Masking Boots

Reusable masking boots are used where connector protection, repeatability and labour reduction are priorities. They replace manual masking methods and provide consistent sealing during repeated production cycles.

  • Reusable and precision fitted
  • Reduce masking labour and operator variation
  • Improve sealing consistency
  • Lower total masking costs in repeat production
Engineering note: Not all masking boots are designed to create a liquid-tight seal. Some are used primarily as spray shields, while others are designed for sealing in processes such as dip coating or Parylene masking. Understanding the difference is important when selecting a masking strategy. Read why a connector masking boot does not always prevent coating ingress.

Pre-Cut Masking Shapes

Pre-cut masking shapes are supplied on sheets rather than rolls, allowing operators to peel and place accurately without manual cutting. This improves consistency while reducing waste and preparation time.

  • Sheet-based format for easy handling
  • Paper and polyimide options available
  • Reduced waste compared with manual cutting
  • Improved repeatability and throughput

Masking Tapes

SCH supplies a single process-proven masking tape specification used throughout our own coating services. It is selected because it delivers reliable sealing, clean removal and predictable performance.

  • Silicone-free construction
  • Controlled rubber adhesive system
  • Validated within SCH production
  • Supports contamination-sensitive applications

Masking Dots

Masking dots provide fast, repeatable protection for grounding holes, vias and pads. They eliminate manual tape cutting and improve masking consistency across multiple assemblies.

  • Fast application
  • Clean removal
  • Reduced coating ingress risk
  • Available in rolls, sheets and mixed formats
