Laird Technologies Expands TIM Portfolio

Laird Technologies Inc. has expanded its thermal interface material (TIM) product line with the release of the Tpcm 580SP Series of phase change material (PCM). The Tpcm 580SP is an exceptionally high-performance, screen printable or stencilable TIM with a thermal conductivity of 4W/m-K that provides an alternative to thermal grease.

The PCM pad contains a solvent that assists in processing, which allows for wetting of the surface. After drying, the solvent is moistureless to the touch, and therefore eliminates the mess associated with thermal grease. Once the solvent is removed, Tpcm 580SP begins to soften and flow at temperatures around 45°C, minimizing thermal contact resistance by filling in the microscopic irregularities of the components it touches. Because Tpcm 580SP softens but does not fully change states, it minimizes migration (pump out) under thermal cycling from room temperature to chip device operating temperatures.

The Tpcm 580SP series is available in a 0.5kg or 1kg can for easy manual screen printing and large volume automatic operations. It is ideal for a variety of applications including high frequency microprocessors, notebook PCs, desktop PCs, computer servers, DC/DC converters, memory modules, cache chips, IGBTs, and automotive and optical electronics.
