Therm-A-Gap T652 gap filler
Chomerics Europe, a division of Parker Hannifin, has introduced a thermally conductive dispensable gap filler that results in much lower stress being exerted on delicate components.
Therm-A-Gap T652 is a fully cured, single-component material suitable for filling variable gaps between multiple components and a common heatsink.
It has a high thermal conductivity of 3W/m-k and an operating temperature range of -50C to +150C, making it suitable for use in harsh environments.
Typical applications include automotive ECUs, electrical drives, light-emitting-diode (LED) modules and power semiconductors.
The material is highly conformable at low assembly pressures and is suitable for providing a thermally efficient filler for gaps of between 0.2mm and 4mm.
For applications that require electrical isolation between mating components, Chomerics Europe supplies a version of the material that incorporates 0.25mm-diameter glass beads that create a compression stop.
Therm-A-Gap T652 is RoHS compliant and has a shelf life of 18 months, with no settling in storage.
The material can be applied manually using a syringe or via automated processes.
Various package sizes that suit either high- or low-volume requirements range from 10cc syringes to 5kg (one gallon) pails.
