Henkel Corp. has added two ultra-low modulus Bergquist Gap Pad thermal interface materials (TIMs) to its line of high compliance thermal management products. Bergquist Gap Pad TGP 6000ULM and Bergquist Gap Pad TGP 7000ULM have been formulated with an advanced resin platform to deliver ultra-low modulus capabilities and high thermal conductivity of 6.0 W/m-K and 7.0 W/m-K, respectively.
“As densities increase with electronics miniaturization, maximizing heat dissipation while minimizing assembly stress on delicate components is challenging but essential for reliability,” said Danny Leong, Henkel Global Technology Manager, Thermal Products. “Our new ultra-low modulus TIMs provide this unique performance combination in custom-sized pads with easy handling to enhance process efficiency.”
Begquist Gap Pad TGP 6000ULM and Bergquist Gap PadTGP 7000ULM are very soft pads with high conformability to rough or irregular surfaces, effectively filling intricate gaps and allowing for thorough wet out at the interface for maximum thermal transfer. Historically, marrying ultra-low modulus (Shore 000, ASTM D2240) properties with high thermal conductivity has been challenging at best. However, due to the advanced silicone-based resin formulation and filler package, the new Gap Pads provide low assembly stress alongside high thermal control.
