2 MTC About us Features MODERN COMPANY WITH LONG TRADITION MTC is specialized on the protection of electronic circuits and the environment from high frequency electromagnetic radiation. Therefore we develop, manufacture and sell high quality EMC shielding materials and thermally conductive products. Thereby we use the very latest technologies and work with a network of efficient suppliers. 20 years of experience in the business and steady growth provide guarantees for long term, successful cooperation with our customers and suppliers. MTC is an ISO 9001 and ISO certified company. This means assured quality and ecology-minded production processes All our products are RoHS compliant UL 94 certified product PLEASE NOTE!!! MTC - PART OF AN INTERNATIONAL GROUP In October 2011 MTC was acquired by the UK-listed company Acal plc. With a turnover of more than 250 million euro and over 750 employees worldwide Acal has evolved into an important international service provider - with focus on the distribution of electronic and photonic components, power supply and system components. Acal has offices in 12 European countries. Thus MTC also grows internationally and ensures its customers local presence and pan-european support. MTC s head office is located in Dillingen (Bavaria). This is where you will find the appropriate contacts for commercial matters and technical support. The production and delivery of our goods are also controlled from here. MTC also has a sales office in Hong Kong. We provide services for the complete Asian market from this base. Custom length available Optionally available on endless rolls Optionally available with Wide Release Liner Optionally available with several items on shared carrier sheet (Sheet Type Package) All data is provided for guidance only due to the varied conditions of potential use which are beyond our control. All recommendations or suggestions are given without guarantee or responsibility on our part and users should make their own test to determine suitability. emci MTC has manufacturing sites in Germany and South Korea. With Regens-Wagner-Stiftung, a facility for disabled people in Dillingen and our sister company EMC Innovation in Incheon we guarantee our customers short reaction times and high flexibility. Features STANDARD OR CUSTOMIZED SOLUTIONS Our product portfolio includes both an extensive range of standard products and products tailored for specific customer needs. Our customers can rely on our solutions being perfectly tailored to their wishes and needs.

3 Thermally Conductive Paste Thermally conductive paste is the most common material used in systems and devices for thermal management. Main criteria for choosing thermally conductive paste are the thermal properties as well as the processing capacities. Thermal conductive paste builts a thin binding film for very good thermal conductivity through the low thermal resistance. With electronic systems and equipments are getting smaller and, at the same time, clock speed is rising, thermal management becomes more and more important. Heat must be transferred from the component to the heat think or any other type of cooling device because heat causes: slower operation speed early failures other power problems. To increase heat dissipation it is suggested to use thermally conductive products as a connection between the hot spot and the cooling device. The connection (without use of an appropriate thermally conductive product) can consist of air up to 80%. Thermally conductive materials have been developed to compensate uneven surfaces. By displacing the air with a highly conductive material heat dissipation is increased and the module is better cooled. Due to low viscosity of the material it can be applied by silk screening or masking technology. Our product range includes thermally conductive pastes with a thermal conductivity between 0.9 up to 4.5 W/m*K.

We offer a variaty of materials like: conductive paste gap filler thermally conductive tapes thermally conductive insulators 4 - Paste 5

4 Gap Filler Thermally conductive gap fillers offer, besides excellent thermal properties, the ability to even small, medium and big gaps and tolerances between the component (hot spot) and the cooling device. Gap fillers are based on silicone and are filled with ceramic material. Gap fillers are used in many applications like LEDs audio- and video devices medical instruments notebook computers automotive devices Gap fillers are supplied as die cut gasket or in standard sheets. As far as the thermal conductivity is concerned, material between 1,0 W/m*k to 7 W/m*K is offered. Gap Fillers are sticky by nature. This can be single- or double-sided. The use of double-sided adhesive tapes is not necessary in most cases.

5 Thermally Conductive Tapes Thermally Conductive Insulators Thermally conductive adhesive tapes are used for bonding heatsinks and other cooling devices with the warm component. Thermally conductive insulators are characterized by a good heat dissipation and an excellent dielectric strength. Item number The tapes can be supplied as double sided adhesive film or with fibre glass carrier. They are filled with thermally conductive ceramic or metallic particles. Thermally conductive tapes eliminate the need for external clamps and curing.
