Conformal Coating Masking Dots

Our range of conformal coating masking dots are perfect for all production processes.

Precision masking solutions for conformal coating applications.

At SCH Technologies, we design and supply a dedicated range of conformal coating masking dots that deliver reliable, cost-effective protection for PCBs during coating processes. Compatible with all major production application methods, our masking dots ensure clean, residue-free results every time.

Why Choose SCH Masking Dots?

Some masking dots cause de-wetting in the conformal coating process

Not all masking dots are suitable for conformal coating. Poor-quality products can lead to:
❌ De-wetting and halo effects around the dot
❌ Residues that require extra cleaning
❌ Coating bleed under the dot
❌ Tearing or adverse reactions with the coating material

Our masking dots have been rigorously developed and tested through our own conformal coating services to eliminate these issues, ensuring reliable masking and optimal coating quality.

The Importance of Proper Masking

Masking is a critical step in conformal coating. It protects sensitive components and keep-out areas on PCBs by preventing coating migration, ensuring functional and reliable assemblies. Using the right materials prevents costly rework and performance issues.
