The construction of Gap Pad(R) VO Ultimate; one side has high inherent tack, while the other side has minimal tack.This combination is useful for manual and automated processes. Note: Resultant thickness is defined as the final gap thickness of the application. Resultant Thickness (mils) Thickness vs. Thermal Resistance Gap Pad VO Ultimate 1) Thir ty second delay value Shore 00 hardness scale. 2)Young's Modulus, calculated using 0.01 in/min. step rate of strain with a sample size of 0.79 inch 2. 3) 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. Typical Applications: * Various IC packages * Thermally enhanced BGA packages * Between any heat-generating semiconductor and a heat sink * Computers and peripherals * Telecommunications * Power conversion * Automotive * LED lighting packages Configurations Available: * Sheet form and die-cut parts GPVOU 0.020 140 120 100 80 60 40 20 0 01 0816 0.020", 0.040", 0.060" 0.61 1.21 1.82 2.42 3.03 3.79 Thermal Resistance (C-in2/W) Gap Pad (R): U.S. Patent 5,679,457 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 Netherlands Phone: 31-35-5380684 Fax: 31-35-5380295 The Bergquist Company Asia Headquarters Hong Kong Phone: 852-2690-9296 Fax: 852-2690-2344 All statements, technical information and recommendations herein are based on tests we believe to be reliable, and THE FOLLOWING IS MADE IN LIEU OF ALL WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MARKETABILITY AND FITNESS FOR PURPOSE.
