Galden fluids are low molecular weight perfluoropolyether
(PFPE) fluids having the general chemical structure of:
CF3-[(O-CF-CF2)m-(O-CF2)n]O-CF3
CF3
PFPEs have exceptional thermal and oxidative stability, as well as extreme chemical inertness. Their non-reactivity, high dielectric strength, low toxicity, non-flammability and non-solvent features make PFPEs ideal for electronic reliability testing including thermal shock and hermetic seal testing.
All Galden grades are:
• Environmentally safe-do not damage the ozone
• Highly inert
• Good heat transfer medium
• Chemically and thermally resistant
• Non-toxic

Thermal Shock Testing
Thermal Shock testing is conducted to determine the resistance of a device to extreme temperature changes. The test is carried out by alternately immers- ing the devices in liquid baths maintained at two dif- ferent temperatures, as specified in MIL STD 883, Method 1011, or MIL STD 202, Method 107.
Traditionally, 2 different fluids were used in both the hot and cold baths. This practice, while conforming to the MIL STD, presents the following problems: high fluid loss from the cold bath; cross contamination between the hot and cold baths; extensive machine down time; and dual fluid inventory.
Single Fluid = Lower Costs
Galden D02TS is a single fluid which replaces the dual fluid system. D02TS meets the MIL STDS 883 and 202
for both the hot and cold baths. The single fluid solu- tion allows for a dramatic decrease in operating costs by:
• Decreasing fluid consumption
• Reducing machine downtime
• Eliminating cross contamination
• Reducing inventory to a single fluid
For use in condition D, E or F, the following military approved GALDEN fluids can be used:
Condition D - D05 / D100, D80
Condition E (Hot test) - D02
Condition F (Hot test) - D05

Hermetic Seal Testing
To guarantee the hermeticity of sealed devices, a leak test procedure as defined by MIL STD 883, Method
1014, MIL STD 750, Method 1071, or MIL STD 202, Method 112 is performed.
Specific physical property requirements have been
defined in 883 for detector and indicator fluids:

Galden DET: Detector Fluid Specifically
Designed for Vapor Detection Systems
• Type I fluid that meets the requirements of
MIL-STD 883
• Lower consumption with respect to traditionally used Type I approved products
• Higher reliability as the result of both low and high boiling point components in the fluid
• High boiling point components enter the devices via the large leaks and remain liquid until the test is performed
• Low boiling point components penetrate into the small leaks
• Tested and approved by the major equipment manufacturer of Vapor Detection Systems
Galden DET can also be used in bubble test equipment as a detector fluid.
Galden D02: A Low Consumption Indicator Fluid
• Higher boiling point, reducing evaporative loss
• Lower liquid density than competitive fluids, reducing operating costs
• Lower vapor pressure at test temperature, minimizing fluid loss
Galden D03: A Lower Cost Indicator Fluid for
Non Military Applications
• Lower consumption compared to other commercially available indicator fluids
To complete the product offering, Solvay Solexis also offers MIL-STD approved Galden D/80, aType I detector fluid and Galden D/100, a Type III
detector fluid.
