New generation of non-silicone dispensable thermal gels

The Chomerics Division of Parker Hannifin Corporation has released THERM-A-GAP GEL 40NS, the next iteration in its silicone-free, thermally conductive gels. This one-component, low-outgassing material provides a special formulation to satisfy the stringent requirements of silicone-sensitive applications such as optical equipment, camera modules, high-performance sensors and data storage devices.

Providing heat-transfer performance of 4W/m-K thermal conductivity, users of the gel will find a thermally reliability material in an ultra-low compression force package: it deforms readily under assembly pressure, minimising stress on components, solder joints and leads. The fully cured and dispensable product needs no mixing and keeps the conventional advantages of the company's line of thermal gels, offering seamless integration into high-volume, automated assembly applications, as well as rework and field repair situations.

The thermal gel reliably conforms to coarse surface irregularities, displaces air gaps and takes up manufacturing tolerances on heat-generating components. The product supplies low thermal impedance at bond lines as thin as 0.15mm (0.006").

"The consumer electronics, automotive, and telecommunications industries have spent years waiting for a high-performance, reliable, non-silicone solution that fits into the portfolio of dispensable and cost-effective thermal interface materials," says Ben Nudelman, global market manager, Chomerics Division. "We're beyond excited to launch a product that finally meets these demands and has a combination of physical and thermal properties that is unmatched in the industry today."

Needing no secondary curing, the gel is an excellent solution for applications that must decrease the risks associated with silicone oil migration or contamination or for devices manufactured in silicone-free facilities.

"The global electronic assembly and manufacturing ecosystem continues to adopt strict material controls," explains Nudelman. "This, along with advances in optical data transmission, electric vehicle (EV) technology and state-of-the-art sensors, leads to nearly limitless applications for our newest thermal material."
