Fluorinert(tm) Electronic Liquids

Fluorinert(tm) Electronic Liquids are part of a family of fully-fluorinated compounds known as perfluorocarbons, or PFCs. For more than forty years, Fluorinert liquids have been used as heat transfer media for direct contact cooling, automated testing, reflow soldering, etching, CVD and more.

MIL-STD 883, Test Method 1014, MIL-STD 750, Test Method 1071, and MIL-STD 202, Test Method 112 specify Fluorinert(tm) liquids for gross leak testing of microelectronic circuits and components.

Fluorinert liquids offer:

  • Excellent dielectric properties
  • A wide range of boiling points
  • Good material compatibility
  • Low toxicity
  • Non-flammability
  • Zero Ozone Depletion Potential (ODP)

Application:

  • Heat Transfer
  • Gross Leak Testing
  • Particulate cleaning
  • Vapor Phase Soldering
