Thermal Interface Material

RAND Manufacturing provides precision die cutting and slitting services for thermal interface material (TIMS) types that are used in electronics to improve reliability and prevent premature failure. Examples include the die cut gap pads that are used between heat-generating electronic components and heat sinks or other substrates.

Types of Thermal Interface Material

RAND Manufacturing works with the following types of TIMs for today’s demanding applications.

Thermal Adhesives

Thermal adhesives move heat and bond components to a heat sink or thermal path. They can be supplied as a conductive glue, a thermal paste, or as double-sided tape. Thermal adhesives are used to bond integrated circuits to heatsinks and can replace mechanical fasteners.

Thermal Caulks

Thermal caulks are sealants that are used to displace air gaps and promote heat conductivity between materials. When cured, the thermal caulk leaves a permanently flexible layer that supports joint movement without cracking during thermal expansion.

Thermal PSA

Thermally conductive pressure-sensitive adhesive tapes (PSA) are filled with ceramic or metallic powders and require initial contact pressure to conform to irregularities in mating surfaces. They differ in terms of peel strength, lap and die-shear strength, holding power, and thermal resistance.

Graphite Films

Graphite films can be used with or without a thermal PSA. They have thermally conductive properties and can be converted into complex die cut parts. Applications include the reduction of hot spots and the protection of sensitive thermal components.

Thermal Glues

Thermal glues are usually made of zinc oxide and silicone, although some products contain liquid metal for a higher thermal conductivity. They are used to dissipate heat from a computer’s central processing unit (CPU) and transfer it to the surrounding air through a metal heat sink.

Silicone Pads

Silicone pads are pre-formed rectangles of silicone material that are used on the underside of heatsinks to aid the conduction of heat away from the component that is being used. Silicone withstands a wide temperature range along with moisture and some chemicals.
