Description
Custom masking dot and shape sheets provide a flexible solution for conformal coating and electronics coating applications where standard masking formats are not suitable. They are manufactured to order and designed to support precise, repeatable masking on complex electronic assemblies.
Custom masking is particularly useful for applications involving complex connectors, irregular component geometries, dense PCB layouts or defined keep-out areas that cannot be effectively masked using standard dot rolls, A4 dot sheets or masking tapes.
Masking dots and shapes are produced to match specific component footprints or design constraints and supplied in A4 sheet format for efficient workstation handling and consistent application during preparation and production.
How the custom masking process works
- Submit your custom masking requirements using the request form
- Provide details such as dot size, shape, layout, quantity and application
- Upload a drawing, PCB file, photograph or sketch (rough drawings are acceptable)
- SCH reviews the request to confirm feasibility and lead time
- Once approved, a secure payment link is provided and manufacture begins
Typical applications
- Complex or non-circular connectors
- Component-specific keep-out zones
- High-density PCB layouts
- Unusual pad, via or test point geometries
- Repeatable masking for specialist or low-volume assemblies
All custom masking sheets are reviewed prior to manufacture to ensure correct fit, adhesion and performance within conformal coating processes. This review step helps prevent incorrect supply and supports reliable, repeatable coating results.
For applications that do not require bespoke masking formats, SCH also supplies standard masking dot rolls, A4 masking dot sheets and masking tapes as part of our wider masking range.
Request custom masking
To request custom masking dot or shape sheets, please submit your requirements using the custom masking request form. Our team will review your application and confirm feasibility, lead time and ordering details before manufacture.
