Masking is necessary because conformal films like parylene and liquid coatings become insulative after drying, disturbing the performance of such critical components as connector contacts. Custom reusable boots – also called caps or plugs — protect assembly parts in those keep-out areas that must not be coated. In comparison to masking materials like tapes and […]
Masking For Conformal Coating Printed circuit boards (PCBs) and related electrical assemblies benefit from the protection of conformal coatings. However, because the films are insulative when dry, they can disrupt operation of the assemblies’ electrical components, items like capacitors, connector contacts, diodes, operational amplifiers, resistors, or transistors. Conformal coating masking

Parylene deposition takes place at the molecular level. Applied at room temperature through CVD processing, the typical thickness of parylene conformal film is in the microns-range. Advantages of parylene coatings include: Excellent material properties, adhering to a wide range of substrate surfaces, biocompatibility, chemical/corrosion resistance, reliable dielectric performance and thermal sta
