One-part, cure-in-place TIMs – Henkel has developed two new, one-part, cure-in-place thermal management materials to address the requirements for simplified processing and eliminate the concerns around dispensing speed with pre-cured, one-part gels. The first, a Bergquist Liqui Form material, has a thermal conductivity of 3.5 W/m-K and, once dispensed, cures at room temperature. This material is ideal for applications that require fast and easy processing, low assembly stress and a robust final cured modulus for lifetime gap stability. With a thermal conductivity of 4.5 W/m-K, the second one-part TIM is a silicone-free Bergquist Gap Filler moisture-cure material designed for applications where silicone is a concern (for example, optical systems in ADAS, industrial automation drives, and PLCs) and high-temperature stability of up to 150°C is required.
Low-volatility liquid gap fillers – Delivering robust thermal conductivity and the mechanical property benefits of silicone, Henkel’s Bergquist Gap Filler TGF 1500LVO and Bergquist Gap Filler TGF 3500LVO cure-in-place TIMs are low-volatility formulations designed to ensure outgassing is minimized. The two-part materials, with 1.8 W/m-K and 3.5 W/m-K thermal conductivity, respectively, are well-suited for high-throughput operations where automated application is beneficial. As liquid mediums, the materials are conducive to miniaturized, intricate designs and can flow in and around tight spaces to ensure excellent gap filling at the interface for optimal heat dissipation.
Low-voiding, temperature stable solder paste and high reliability alloy – Adding to its line of award-winning Loctite GC temperature stable solder pastes, Henkel has developed a low-voiding formulation compatible with multiple component sizes including large, thermally-challenged devices such as MOSFETs and QFNs, which are often integrated into power and automotive control applications. Like all Loctite GC materials, Loctite GC 18 offers stability in transit, in storage, and on the production line for the lowest cost-of-ownership and excellent performance and reliability across a wide spectrum of product builds. In addition, the company’s high reliability 90iSC lead-free solder alloy will be on show. Designed in cooperation with automotive manufacturers, Henkel’s 90iSC has been formulated to withstand the demands of harsh environments, delivering high operating temperature stability beyond that of conventional SAC alloys.
Henkel’s team of technical specialists will expand on the benefits of the above materials in a series of three presentations taking place throughout the three-day PCIM Europe event.
