Pasty thermal conductive material
To operate electronic semiconductors in a temperature range given by the manufacturer is essentially important for its functional reliability and lifetime. The thermotechnical contacting of the electronic component on the particular heat sink plays a decisive role for an efficient working thermal management. Thermal interface materials, so called TIM, equipped with various technical parameters provide excellent solutions in terms of thermotechnical contacting. The thermal total resistance is composed by an addition of the single thermal transfer resistances along the thermal path which the heat flow has to overcome. The lower the figure of the thermal transfer resistance the better the thermal conduction and in sum the thermal total resistance. Fischer Elektronik GmbH & Co. KG extends their extensive product portfolio of contact materials especially for the application scenarios of the thermal contacting by a fluid gel thermal conductive material with its name GEL S 18. The thermal conductive material GEL S 18 is a pasty, gel-like and fully hardening thermal conductive material in a two-component system. GEL S 18 is well-suited for a compensation respectively filling of small or big empty spaces in electronic devices such as the mounting of PCBs on heatsinks. The viscoelastic paste has a very good construction flexibility connected with excellent adhesive properties. This allows an easy handling as well as a secure mounting of the components to be contacted. Furthermore the material characterises itself by a very good thermal conductivity with a low thermal impedance as well as a wide range of operating temperatures. GEL S 18 is easy, also fully automatic, dispensable and can be deformed effortless already with lower compressive force whereby the load on the electronic components is reduced significantly which otherwise would lead to early functional failures of the device or to damages of the PCB. Moreover the material is listed with UL 94 V-0 and durable six months at a storage temperature of 25 °C. The pot life at room temperature is 60 minutes with the associated hardening time of 300 minutes at room temperature and 10 minutes at 100 °C. The article GEL S 18 is supplied in a 50cc double chamber cartridge with three additional static mixing tube as a standard. Optionally an applicator gun for this kind of cartridge is available.
