Thermal Interface Materials (TIM's) are our biggest & fastest growing product category. As electronic devices get smaller - known as miniaturisation - we build PCB’s with higher energy density with more components in a smaller space and ever increasing operating temperatures. It means we need better and reliable cooling and temperature control of our devices when we use them.

It’s all about the heat transfer to the heat sink and thermal ratings, bond line thickness, surface contact all play a part.  Our TIM pastes offer an efficient heat path and thermal stress resistance which will extend the product life of your electronic devices.

TIM adhesives are offered both as air cured and heat cured and are available in a range of viscosities, thermal ratings and a variety of pack sizes from syringes, tubes, cartridges and pails to aid consistent dispensing.

In this post we are highlighting Techsil’s Top Ten of our most popular thermal management products and their features and benefits which might hopefully help you to select the right product for your application.  Here goes…
