Conformal Coating Boots vs Tape:  Making the Right Choice

Posted by Sean Horn on Fri, Jan 27, 2017 @ 07:24 AM

Masking tapes and boots both protect components for a selected range of masking functions.  Choosing between the two is crucial to achieving optimal masking protection.  Conductivity needs to be maintained in all cases.  In addition, such operational factors as the:

Different Types of Masking for Conformal Coatings

Posted by Sean Horn on Fri, Jan 13, 2017 @ 07:45 AM

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 protects specified regions of PCBs and related assemblies from being conformally coated during film application. These components must remain uncoated to function as designed.  Consisting of masking appliances constructed with appropriate materials, masking systems prevent migration of conformal coatings into designated keep-out areas.  Masking processes enacted prior to coating application assure the conformal materials DO NOT invade designated keep-out areas.

Parylene Masking: Materials and Methods

Posted by Sean Horn on Fri, Jan 06, 2017 @ 07:45 AM

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.
