Actual application performance is directly related to the surface roughness, flatness and pressure applied. Bergquist Q-Pad 3 eliminates problems associated with thermal grease such as contamination of electronic assemblies and reflow solder baths. Q-Pad 3 may be installed prior to soldering and cleaning without worry.When clamped between two surfaces, the elastomer conforms to surface textures thereby creating an air-free interface between heat-generating components and heat sinks. Typical Applications Include: Fiberglass reinforcement enables Q-Pad 3 to withstand processing stresses without losing physical integrity. It also provides ease of handling during application. * Sheet form, die-cut parts and roll form * With or without pressure sensitive adhesive * 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: Building a Part Number Standard Options NA Section E - AC - 12/250 - Section D 0.005 Section C - Section B Section A Q3 NA = Selected standard option.
