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.

5 Advantages of Cationic Epoxies

Posted by Dan Griffin on Aug 19, 2019 10:00:00 AM

Cationic and free radical are the two most popular mechanisms for UV adhesives. Approximately 93% of the UV market is in free-radical chemistry while cationic has about 7%. Although a minority of the market, cationic adhesives provide strategic advantages over traditional free-radical acrylate chemistries. These advantages are detailed below.
