“PGS” Graphite Sheets ÒPGSÓ Graphite Sheets PGS (Pyrolytic Graphite Sheet) is a heat sink sheet with high thermal conductivity and high flexibility. PGS is made of graphite with a structure that is close to a single crystal. This is achieved by highly oriented polymer film sheet, a process which has never been implemented before. n Recommended applications n Features l Notebook personal computers,DVDs,DVCs,mobile phones l Semiconductor manufacturing equipment (Sputtering,Dry etching,Steppers) l Optical communications'equipment l Excellent thermal conductivity:600 to 800W/(m ¥ K) (Twice as high as copper, three times as high as aluminum) l Lightweight:Specific gravity:1.0g/cm3 (1/9 that of copper,1/3 that of aluminum) l Flexible and easy to be cut or trimmed. (withstands repeated bending) l Low thermal resistance n Explanation of Part Numbers E Y G S 1 8 2 5 1 0 E E n Dimensions in mm Part No. Dimension X (Short) Dimension Y (Long) Thickness EYGS182510 18.0±0.5cm 25.0±0.5cm 0.10±0.05mm EYGS131810 12.5±0.5cm 18.0±0.5cm 0.10±0.05mm EYGS091310 9.0±0.5cm 12.5±0.5cm 0.10±0.05mm n Characteristics Characteristics Specification Thickness 0.10 ± 0.05 mm Density 1.0 g/cm3 Thermal conductivity a-b plane 600 to 800 W/(m Electrical conductivity 10000 S/cm Extensional strength 19.6 MPa Expansion coefficient Expansion coefficient Heat resistance Bending(angle 180,R5) a-b plane 9.3 ´ 10-7 1/K c axis 3.2 ´ 10-5 1/K 400 ûC 10000 cycles ¥ K) “PGS” Graphite Sheets ± n Thermal conductivity of PGS compared to other n Layered structure of PGS materials n Dimensions in mm (not to scale) EYGS182510 Type PGS only EYGM131810SS EYGM131810SW EYGA091310K Silicon layered type Onesided type Doublesided type EYGA091310A Doble-sidePolyimide tape adhesive attached tape attached type EYGC091310A EYGL@@@@@@P2 Acrylic PETadhesive covered (one side) attached type type EYGM091310CT Conductive adhesive tape type Structure Thickness (µm) 100±50 200±50 300±50 130±50 130±50 110±50 150±50 (1 pcs.) 350±50 (3 pcs.) 130±50 Thermal resistance (ûC/W) 0.4 1.0 1.4 2.4 1.7 0.8 2.0 1.6 Thermal conductivity (direction of the 600 to 800 250 to 300 250 to 300 sheet surface) (W/m¥k) 500 to 600 500 to 600 550 to 650 500 to 600 500 to 600 Withstand temperature max.

Following ÒPrecautions for SafetyÓ and ÒApplication NotesÓ shall be taken in your major consideration. If you have a question about the Precautions for Handling, please contact our engineering section or factory. 1. Precautions for safety 1.1 1.2 1.3 1.4 The PGS shall be used within the specified operating temperature range. Never rub or contact with hard materials to avoid scratches because the PGS is soft. If the PGS have a line or a fold, that may affect thermal conductivity. The PGS shall not be used with acid. The PGS shall not be used in contact with iron at 400 ûC or more 1.5 The PGS shall not be exposed to salt water or direct sunlight in use. The PGS shall not be used under corrosive gases (hydrogen sulfide, sulfurous acid, chlorine, ammonia etc.). 1.6 Our PGS has been developed for general industry applications.Ask our engineering section or factory prior to special applications such as for medical, for aerospace and aircraft work. 1.7 Never touch a using PGS because it may be high temperature. 2. Application notes 2.1 When the load forcing to separate is added or pointed edge is touched,use the PGS with protecitive materials because it may be torn or have a through hole. 2.2 If overheated, it does not work normally. 2.3 thermal conductivity depends on operating methods. Test the adaptability of PGS for your application before use. 2.4 The PGS has conductivity. If insulation is required, the PGS should be provided insulation. 2.5 Long term storage ¥ The PGS shall not be stored under severe conditions of salt water, direct sunlight or corrosive gases (hydrogen sulfide, sulfurous acid, chlorine, ammonia etc.). ¥ The PGS shall not be stored with acid.
