Conformal Coating for PCB's

Posted by Sean Horn on Fri, Jul 21, 2017 @ 07:47 AM

Printed circuit boards (PCBs) electrically connect and power all but the simplest electronic products.  To function as designed, PCBs and their components – capacitors, resistors, etc. – require protection against operating problems caused by corrosive liquids, dust, physical shock, temperature extremes and, in the case of medical implants, bodily fluids.  Conformal coatings are applied over PCBs to safeguard mechanisms and maintain functionality.

All About Conformal Coatings

Posted by Sean Horn on Fri, Jun 23, 2017 @ 08:00 AM

Conformal coatings insulate printed circuit boards (PCBs) and similar electronics; their protection increases devices’ tolerance to harsh environments.  The result is undisturbed function through a range of frequently harsh operating environments and performance conditions.  Conformal coatings provide these services for aerospace/defense, automotive, consumer, and medical devices.  They are adaptable for LED uses, as well as MEMS/nanotechnology, and other uses.

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.
