Q-Pad 3

Features & Benefits

  • Thermal impedance: 0.35°C-in2/W (@50 psi)
  • Eliminates processing constraints typically associated with grease
  • Conforms to surface textures
  • Easy handling
  • May be installed prior to soldering and cleaning without worry

Description

Henkel 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 and 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.

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
  • Between a heat sink and a chassis
  • Under electrically isolated power modules or devices such as resistors, transformers and solid state relays
