Conformal Coating Masking Dots
Simple, Reliable Masking for Repeat Features
Masking dots are the quickest way to protect grounding holes, vias, and pads during conformal coating. By eliminating the need to cut tape, dots deliver faster preparation, consistent results, and clean edges across multiple assemblies.
All SCH masking dots are silicone-free, avoiding contamination and ensuring your coating adheres properly.
Why Choose SCH Conformal Coating Masking Dots?
Our dots are designed to be used with conformal coatings. They provide the perfect solution for the process including:
- 100% silicone-free adhesives for coating reliability
- Designed specifically for grounding holes, vias, and pads
- Clean removal with no adhesive residue
- Consistent edges to minimise rework
- Supplied on rolls for volume or sheets for individual projects
- Available in a wide range of diameters, with custom sizes on request
Not all dots are suitable for the conformal coating process. Using poor-quality products can cause significant problems such as de-wetting and halo effects around the dot, adhesive residues that require additional cleaning, coating bleed underneath the dot, or even tearing and adverse reactions with the coating material.
Our dots have been rigorously developed and tested through our own coating services to eliminate these issues, ensuring reliable masking and optimal coating quality.
Part of a Complete Masking Range
At SCH Technologies, we supply a full portfolio of conformal coating masking solutions designed to do far more than standard tapes.
- Custom Masking Boots – Precision-moulded, reusable boots that protect connectors and components with greater efficiency and reliability than tape.
- Masking Dots & Pre-Cut Shapes – Quick, repeatable masking for vias, pads, and defined board areas where accuracy matters.
- Complete Masking Kits – Tailored sets that combine tapes, dots, and boots to match your PCB design and streamline production.
Together, these solutions create a complete masking system that helps you:
- Stay compliant with IPC conformal coating standards
- Improve consistency and reduce rework
- Cut labour costs by speeding up masking steps
- Eliminate common coating defects to boost reliability
Choosing the right masking materials from the outset means better coating quality, faster throughput, and lower total costs. SCH masking products are proven in our own coating lines and trusted by manufacturers worldwide across electronics, aerospace, automotive, defence, and medical sectors.
Conformal Coating Masking Dots FAQs
Why use dots instead of tape?
Dots are faster for repeat circular features like vias, grounding holes, and pads. Tape is better for long edges or irregular areas.
Do the dots leave residue?
No. Our silicone-free adhesives are designed for clean removal after coating and cure.
Can I order custom sizes?
Yes. We can supply dots in any diameter or shape to match your PCB layout.
Are dots suitable for selective coating?
Yes. They’re ideal for protecting repeat pads and vias when running automated selective coating programs.
