How to Setup a Conformal Coating Spray Operation

Posted by Sean Horn on Fri, Jun 30, 2017 @ 08:00 AM

As the name suggests, spray coating is a method of application where the conformal coating is sprayed directly onto the printed circuit board (PCB).  It is typically applied manually in a spray booth or by aerosol, although it can be automated/robotic, for selective coating assignments.

5 Keys to the Conformal Coating Process

Posted by Sean Horn on Fri, Jun 16, 2017 @ 07:49 AM

The conformal coating process requires watchful administration to ensure successful implementation.  Recognizing the unique properties of various coating-types is critical to selecting the kind most applicable to the project and its purposes, while meeting clients’ material and operational specifications.  Regardless of the coating material and the substrate, these five fundamental procedures are essential to good conformal films.

Managing the Conformal Coating Process

Posted by Sean Horn on Fri, Jun 09, 2017 @ 07:47 AM

Managing the conformal coating process begins with a precise definition of coverage required.  Pre-process negotiations between the client, the coating provider, and end-user, clarify coating requirements.  They include agreement about whether:

All about the Conformal Coating Process

Posted by Sean Horn on Fri, Jun 02, 2017 @ 07:40 AM

Liquid application resins acrylic, epoxy, silicone and urethane are applied to electronic circuitry in a liquid format by brush, dip or spray techniques, either manually or through robotic processes; they require curing before they can be used.

Cracking in Conformal Coating:  Major Causes and Preventative Strategies

Posted by Sean Horn on Fri, Feb 10, 2017 @ 07:45 AM

Conformal coatings protect printed circuit boards (PCBs) and similar electronic assemblies used for a wide range of aerospace, automotive, consumer, defense and medical applications.  Coatings effectively cover PCBs, shielding them from contaminants, liquid incursions, temperature fluctuations and other conditions potentially hazardous to component performance.  However, problems can develop if their preparation, application, and drying processes are inappropriately managed.

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 causes bubbles in conformal coating?

Posted by Sean Horn on Wed, Sep 12, 2012 @ 09:41 AM

One of the causes for failure during conformal coating inspectionare bubbles.  Bubbles are trapped pockets of air under coating.  The bubbles can cause voids in the coating and Here we will identify the six largest causes of bubbles.

Conformal Coating Service: What to look for?

Posted by Sean Horn on Thu, Jun 28, 2012 @ 08:48 AM

After you have decided to outsource conformal coating, it is time to evaluate and decide on a vendor.  What criteria should you use to evaluate your potential vendors and how should you make a final decision?

One thing to consider is the coating house’s experience level.  Developing solid procedures and processes for conformal coating take time and experience.  Many new vendors claim to be able to apply conformal coating as well as the experienced guys, but fall short whenever they run into issues they do not have the experience to troubleshoot.  It will be tough to get referrals from your coating house, as a lot of times they are required to sign a non-disclosure agreement.  A good way to evaluate their experience level would be to ask how many years they have been in business and their typical weekly, monthly, and yearly volumes processed.  A visit to their facility, if warranted by the volume of the project, should give a good indication of the seriousness of their abilities.
