Galden® PFPE and H-Galden® HFPE fluids 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.
Thermal Shock testing is conducted to determine the resistance of a device to extreme temperature changes. The test is carried out by alternately immersing the devices in liquid baths maintained at two different temperatures, as specified in MIL STD 883, Method 1011, or MIL STD 202, Method 107.
Traditionally, two 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.
All Galden and H-Galden grades are:
Environmentally safe - they do not damage the ozone layer
