When applying a conformal coating, there are components whose functionality would be disrupted by the coating. To prevent this, a masking process is used. This masking is applied to connectors, header pins, plugs, and sockets.
Sorting Through Masking Solutions
There are a few different masking materials and based on the surface being coated; your solution options will vary. When choosing a masking solution, you should also take into account conformability and cost-effectiveness. The primary options are dots, tape, and boots.
- Dots: Small stickers placed over contact before coating.
- Tape: Liquid, peel-able masking material.
- Boots: Custom-made covering.
All masking solutions are used for specific purposes, but the benefits of making boots rise above the rest.
Why Masking Boots are Beneficial
You will have a diverse and versatile advantage by choosing to mask with a boot. Masking boots are superior for covering whole or partials areas of a surface quickly and successfully. Masking boots are custom made to the requirements of the medium. Masking boots work with parylene conformal coating perfectly and eliminate the need for masking and de-masking allowing you to save time and labor costs.
When selecting a boot design, take a few factors into account. First, consider the size and shape of the component you need to coat and its location on the medium in question. Second, the conformal coating covering the assembly and its application process will also affect the precision of the boot.
