Encapsulating for PCBs: How to Choose the Right Method

Posted by Vlad David on Feb 20, 2024 12:09:20 PM

If you're familiar with HumiSeal through our blogs, you know we are big fans of conformal coatings. This is for good reason; with advancing conformal coating technology, innovative LED and UV curable coatings offer incredible protection for a large range of applications.

Conformal coatings are just one method of circuit board protection available to engineers. Those involved with PCBs may be familiar with the terms encapsulation. Encapsulation is a tremendously powerful method to secure and protect PCBs by submerging them in a protective material. In many cases, this is more desirable than selectively applying conformal coatings.

Ruggedization of Electronic Circuits? Encapsulation is One of The Best-kept Protection Secrets

Posted by Vlad David on Oct 25, 2023 12:54:46 PM

It's no secret that conformal coatings increase the lifetime of electronic devices by providing a thin barrier that strengthens their ability to withstand harsh environmental conditions. That said, a lesser-known truth is adhesives and encapsulants provide a significantly higher level of protection on the entire assembly.

Why is that? Well, adhesives and encapsulants promote assembly protection by:

  • creating environmental seals that protect against moisture and corrosion
  • providing high-temperature resistance
  • increasing shock and vibration-dampening
  • generating strong bonds to a variety of substrates
  • maintaining low shrinkage
  • offering thermal conductivity

5 Simple Steps to Eliminate Bubbles in Potting Encapsulants

Posted by Humiseal Editor on Apr 16, 2018 11:00:00 AM

Encapsulant solutions are commonly used to enhance protection of circuit boards from environmental and liquid contaminants, chemical attack, and electrical shortages. While potting materials provide many positive attributes when used to protect PCBs, sometimes other issues arise during and post application of these compounds. This blog focuses on “bubbles” forming within the encapsulant itself.
