Features and Benefits
• Thermal impedance:
• Eliminates processing constraints typically
• Conforms to surface textures
• Easy handling
• May be installed prior to soldering and
Bergquist Q-Pad 3 eliminates problems
associated with thermal grease such as conta-
mination 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.
Fiberglass reinforcement enables Q-Pad 3 to
withstand processing stresses without losing
physical integrity. It also provides ease of
handling during application.

THERMAL PERFORMANCE vs PRESSURE
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.
