Q-Pad II (R) Foil-Format Grease Replacement for Maximum Heat Transfer Features and Benefits TYPICAL PROPERTIES OF Q-PAD II PROPERTY Color * Thermal impedance: 0.22C-in2/W (@50 psi) * Maximum heat transfer * Aluminum foil coated both sides * Designed to replace thermal grease IMPERIAL VALUE Black METRIC VALUE Black Reinforcement Carrier Aluminum Aluminum -- Thickness (inch) / (mm) 0.006 0.152 ASTM D374 Hardness (Shore A) Continuous Use Temp (F) / (C) ELECTRICAL Dielectric Breakdown Voltage (Vac) TEST METHOD Visual 93 93 ASTM D2240 -76 to 356 -60 to 180 -- Non-Insulating Non-Insulating ASTM D149 Dielectric Constant (1000 Hz) NA NA ASTM D150 Volume Resistivity (Ohm-meter) 10 2 10 2 ASTM D257 Flame Rating V-O V-O U.L.94 THERMAL Thermal Conductivity (W/m-K) 2.5 2.5 ASTM D5470 THERMAL PERFORMANCE vs PRESSURE Pressure (psi) 10 25 50 100 200 TO-220 Thermal Performance (C/W) 2.44 1.73 1.23 1.05 0.92 Thermal Impedance (C-in2/W) (1) 0.52 0.30 0.22 0.15 0.12 1) The ASTM D5470 test fixture was used.The recorded value includes interfacial thermal resistance.These values are provided for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied. Q-Pad II is a composite of aluminum foil coated on both sides with thermally / electrically conductive Sil-Pad rubber.The material is designed for those applications in which maximum heat transfer is needed and electrical isolation is not required. Q-Pad II is the ideal thermal interface material to replace messy thermal grease compounds. Typical Applications Include: Q-Pad II eliminates problems associated with grease such as contamination of reflow solder or cleaning operations. Unlike grease, Q-Pad II can be used prior to these operations. Q-Pad II also eliminates dust collection which can cause possible surface shorting or heat buildup. * Between a transistor and a heat sink * Between two large surfaces such as an L-bracket and the chassis of an assembly * Between a heat sink and a chassis * Under electrically isolated power modules or devices such as resistors, transformers and solid state relays Configurations Available: * Sheet form, die-cut parts and roll form * With or without pressure sensitive adhesive Building a Part Number Standard Options Sil-Pad (R): U.S. Patents 4,574,879; 4,602,125; 4,602,678; 4,685,987; 4,842,911 and others www.bergquistcompany.com The Bergquist Company North American Headquarters 18930 West 78th Street Chanhassen, MN 55317 Phone: 800-347-4572 Fax: 952-835-0430 The Bergquist Company European Headquarters Bramenberg 9a, 3755 BT Eemnes Netherlands Phone: 31-35-5380684 Fax: 31-35-5380295 The Bergquist Company - Asia Room 15, 8/F Wah Wai Industrial Centre No. 38-40, Au Pui Wan Street Fotan, Shatin, N.T.
