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:

Conformal Coating Specifications:  Guidelines for Design, Selection and Application of Conformal Coatings

Posted by Sean Horn on Fri, Sep 02, 2016 @ 07:30 AM

Understanding the characteristics of various conformal coating types, and their interactions with the extreme range of products and materials to which they are applied, ensures optimal function, performance reliability and product-life.   Designers and users of conformal coatings should be aware of the properties of various types of conformal coatings and their interactions with the parts/materials they cover, to protect the products in their respective end-use environments for the expected design-life of each component.

Why Conformal Coat

Posted by Sean Horn on Tue, Jul 16, 2013 @ 11:59 AM

Printed circuit boards are extremely susceptible to a wide range of contaminants that can significantly damage or ruin them in a relatively short period of time. These contaminants include moisture, dust, and harmful chemicals. In addition, electronic circuits are also susceptible to extreme temperatures and environments.

What is the uniformity of parylene conformal coating?

Posted by Sean Horn on Fri, Sep 14, 2012 @ 10:33 AM

Parylene  is often applied to substrates or materials where there is no room for any voids in the protective coating.  These materials are likely to be placed in harmful chemicals, a moisture packed environment, or even the human body.  These are often mission critical devices which can not allow any environmental factors to alter their performance.  Whenever these devices need this stringent level of protection from the elements, parylene is the only logical choice.

Type UR conformal coating examples

Posted by Sean Horn on Fri, Sep 07, 2012 @ 09:39 AM

Type UR (urethane resin) conformal coatings are a popular choice for conformal coating projects because of their resistance to chemical solvents, hardness, and moisture protection.  There are many different varieties of type UR conformal coatings such as:
  • HumiSeal 1A33
  • HumiSeal 1A20
  • Humiseal 1A27
  • Humiseal 2A64
  • HumiSeal 1A34
  • Hysol PC18M
  • CONATHANE CE-1155-35
  • CONAP CE-1170
  • CONATHANE CE-1164
  • Techspray Fine-L-Kote
  • MG Chemicals 4223
  • Electrolube PUC

You should consider using type ur conformal coating whenever your application has any issues with chemical resistivity as type ur coatings are very resistant to chemical solvents.  Type ur conformal coating is also smart to include in any tin whisker mitigation strategy, as NASA studies have shown that urethane conformal coatings are one of the few ways to successfully mitigate tin whisker growth.  Finally, applications that can see any direct mechanical wear against the coating should consider urethane conformal coatings as well.

Will HumiSeal 1B31 mitigate tin whiskers?

Posted by Sean Horn on Tue, Sep 04, 2012 @ 01:20 PM

Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from surfaces where tin (especially electroplated tin) is used as a final finish.  They typically grow from lengths of 1-2 millimeters (mm) but have been observed to lengths in excess of 10 mm.  They are a serious issue in the electronics world because they have been known to cause short circuits between circuit elements.

Why use a conformal coating drying cabinet?

Posted by Sean Horn on Mon, Aug 27, 2012 @ 08:45 AM

There are a lot of different pieces of conformal coating equipment.  Each one of them has their own unique purpose and drying cabinets are no different.  The three main uses of drying cabinets are to extract air from around the assemblies, hold the assembly still during curing, and to protect the card from damage.
