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.

What is the right conformal coating for LEDs?

Posted by Sean Horn on Thu, Jun 21, 2012 @ 11:50 AM

Light emitting diodes (LEDs) are a huge and growing even bigger segment of the electronics industry.  LEDs are expanding into environments that demand a higher l evel of protection in order for the LED to function properly.  One way to get this level of protection is by using conformal coating.

Automated Conformal Coating Spray Robot Issues

Posted by Sean Horn on Fri, Jun 01, 2012 @ 02:17 PM

There are many benefits to using a spray robot for conformal coating.  As always, there are some potential issues that need to be addressed prior to committing to a spray robot such as the MACCS 400.

 One potential issue with considering selective conformal coating with a robotic conformal coating system is misaligned components on the PCB which can potentially damage the spray heads which are moving along a set pattern on the board and the components themselves be damaged as they travel.  Spray heads are one of the most critical parts on the spray robot.  Repairing damage can get costly.
