HENKEL Bergquist microTIM mTIM 1028 (1000 series) micro-thermal interface coating portfolio introduces a new formulation, providing reductions in functional heat experienced by optical transceivers, addressing the thermal challenges of 400, 600 and 800 Gb pluggable optical modules (POMs). Product delivers a more robust solution, providing enduring thermal control for high bandwidth density POMs. These devices are typically constructed with nickel housings and interface with nickel-coated copper heat sinks for system heat removal. Compared to alternatives, product can withstand as many as 500 pulls and insertions without performance degradation and reduces operational temperatures per POM by as much as 0.18°C/W.
