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 INCLUDE • Between a transistor and a heat sink • Between two large surfaces such as an L-bracket and the chassis of an assembly Q-Pad® 3 eliminates problems associated with thermal grease such as contamination • Between a heat sink and a chassis of electronic assemblies and reflow solder • Under electrically isolated power modules or devices such as resistors, baths. Q-Pad® 3 may be installed prior to transformers and solid state relays soldering and cleaning without worry. When clamped between two surfaces, the CONFIGURATIONS AVAILABLE elastomer conforms to surface textures • Sheet form, die-cut parts and roll form thereby creating an air-free interface • With or without pressure sensitive adhesive between heat-generating components and heat sinks. Fiberglass reinforcement enables Q-Pad® 3 to withstand processing stresses without losing physical integrity. It also provides ease of handling during application.
