Thermal Management Non-silicone Pastes Ÿ Silicone Pastes Ÿ RTV’s Ÿ Resins Epoxy Ÿ to 3.4W/m.K 0.9 Ÿ Most components have a maximum, effective operating temperature. Failure to maintain the temperature below this level can lead to a variation in electrical properties and overall increased failure rates. Metal heat sinks are typically connected to components which generate a large amount of thermal energy when in use. These are used to dissipate such energy away from the device to avoid failure due to over-heating. Heat sinks have proven to be very effective over the years however in order to...

Thermal Pastes The ‘Xtra’ Range: HTCX and HTCPX Thermally conductive pastes consist of thermally conductive fillers in a carrier fluid. Thermal pastes do not cure; therefore, they offer the best solution when rework is important and provide versatility by avoiding geometrical restrictions affecting cure. The paste can be applied using a variety of methods e.g. stencil printing, screen printing or automatic dispensing equipment. Electrolube’s ‘Xtra’ range of thermal products are enhanced versions of the non-silicone products HTC and HTCP. These ‘X’ versions are manufactured using one of the...

Potting Compounds For certain types of heat generating circuitry e.g power supplies, it may be beneficial to encapsulate the device in a heat-sink enclosure using a thermally conductive potting compound. Electrolube produces a variety of two-part encapsulation solutions utilising epoxy and polyurethane technologies. ER2074 is Electrolube’s flagship thermally conductive encapsulation product. This highly-filled epoxy resin possesses high thermal conductivity (1.26 W/mK), but as a result is high in viscosity (16700 cPs). ER2183 is a lower viscosity version of ER2074 (5000 cPs). The reduced...

Thermal Conductivity HTC Some techniques only measure the sum of the material’s thermal resistance and the material/instrument contact resistance. Electrolube use a version of the heat-flow method that measures both of these values separately.

It is important that the...
