Conductive Elastomer Discs and Sheets

An economically attractive substitute for silverfilled pastes normally used in target bonding.

When placed between the back of a (clamped, not bonded) target and the cooling well of a magnetron sputter source, these sheets enhance thermal transfer, especially for targets that have poor thermal contact or conductance.

  • Made of a vacuum-compatible 0.020" thick silicone rubber
  • Contain silver-coated copper powder filler
  • Reusable
