A Need-To-Know Guide for Encapsulating PCBs with Thermally Conductive Polymers

Posted by Dan Griffin on May 14, 2024 6:00:00 AM

Thermally conductive polymers conduct and disperse heat away from sensitive electronics and PCB components. There are many different available chemistries for the base material which include polyethylene, epoxy, and silicone chemistries among others. The choice of polymer generally involves matching of desired temperature resistance, hardness, and flexibility among others. Since polymers are normally thermally insulative, conductivity is achieved through the use of various fillers such as metallic or halogenated compounds.

High-Temperature Adhesion and Potting: A Versatile Epoxy Solution

Posted by Dan Griffin on Mar 13, 2024 3:06:32 PM

Things are getting hotter out there, and it can’t all be blamed on global warming! As manufactured products continue to get smaller and lighter, there is often the undesired side effect of increased generation of heat. This is especially true in the electronics and power industries, but it is also a challenge faced in industries, including:

  • Automotive/EV/Battery (Engines, brakes, assemblies…)
  • White goods/appliances
  • Medical devices and wearables
  • Power generation and conversion/inversion
  • Renewable energy manufacture and control
  • And many others….

Keep Your Electronics Cool With Thermal Management Materials

Posted by Editor on Mar 30, 2021 2:00:00 PM

Nobody likes to get too hot, and if your high-tech electronics could talk, they’d say they feel the same way. Heat is their enemy. It reduces longevity and limits reliability, two non-negotiable properties in electronics. The lack of one or both can literally mean the difference between life and death in applications such as autonomous driving and aerospace controls.

How to Increase Flowability & Thermal Conductivity of Your Potting Material

Posted by Kris Hanson on Dec 20, 2018 9:38:39 AM

Thermally conductive silicone products are widely used in the electronics industry to radiate heat away from locales for component survivability while maintaining optimum operating temperatures. For potting and encapsulation applications, circuit board engineers typically specify flowable products that will quickly surround the components after dispensing and become solid at room temperature within an hour or less.
