SILVER-FILLED PASTE PROVIDES SUPERIOR TARGET BONDING


Sputtering operations place higher demands on the bond between target and plate. Materion addresses these needs with its Thermotech TE Vacuum Paste, a silver-filled paste that is an electrically conductive high-vacuum compound specifically manufactured for bonding sputtering targets. It combines excellent thermal and electrical properties with a low vapor pressure sealant that will withstand the high vacuum operating temperature ranges.

DC SPUTTERING OPERATIONS COMPATIBLE AND OTHER ADVANTAGES

Thermotech TE Vacuum Paste is a unique target sealant that has good electrical conductivity making it compatible with Direct Current (DC) sputtering operations and offers the following benefits:

  • Provides substantially better bonding and target cooling
  • Does not contain silicone and is non-hardening
  • Withstands higher operating temperature ranges
  • Absorbs grease and other impurities on metal surfaces
  • Cleans up easily and completely with acetone or methanol
  • Available in single-use kits based on target size

TECHNICAL PROPERTIES OF THERMOTECH TE VACUUM PASTE

When our silver-filled paste is applied, it flows into small scratches and surface imperfections of the sputtering target and its cooling plate. This creates a smooth, level surface that allows for superior bonding to occur. The technical properties of Thermotech TE Vacuum Paste are listed in the chart below.
