Conformal Coating Masking Boots
Masking boots are an integral part of a full masking solution in coating applications for printed circuit boards, whether this is for a liquid conformal coating process or a vapour deposition process such as parylene. Many components and printed circuit board locations must remain uncoated and the purpose of the conformal coating masking boots is to prevent migration of the conformal coatings into components and keep out areas. The use of masking tapes, dots and liquid latex is an effective process in protecting components from ingress of conformal coating. However, the application of the masking can be labour intensive, especially in higher volume applications. Therefore, masking boots can offer a labour saving alternative in both the masking and de-masking stages of the coating process. Where are Conformal Coating Masking Boots Used? Our masking boots provide protection for many different types of components for all conformal coating application techniques. These processes include batch and selective robotic spraying (as an alternative to difficult technical programming), vertical and horizontal dipping and vapour deposition of coatings such as parylene. What Types of Masking Boots are Available from SCH? We can provide both standard and custom boots solutions for a customer depending on their needs. We already have a wide range of custom boots and designs within stock or ready to manufacture. we can quickly match these to your needs. If this is not possible then we help develop a custom solution through our design services to help you get the protection you need in your conformal coating process. The key is to determine the best Return on Investment (ROI) when using masking boots for the customer for their particular application. What Conformal Coating Materials can be used with the Masking Boots? The masking boots are compatible with the full range of conformal coating materials and solvents including all of the parylene compositions and the liquid conformal coatings like acrylics, polyurethanes, silicones and epoxies. The boots are generally made of silicone rubber but alternative materials can be used depending on the application. How are Conformal Coating Masking Boots Used? They are used by applying them over the components such as connectors, plugs and sockets that require protection from the conformal coating applied. They can be simple boots that fit over the top of a connector or a more sophisticated design such as the boot bel
