Electronic devices must be completely sealed to avoid penetration by moisture and potential damage of the electrical response of the silicon chip. To guarantee the hermeticity of devices, a leak test procedure has been defined and ruled by MIL STD 883, MIL STD 750 and MIL STD 202.

Galden® PFPE fluids, extremely inert and residue free, are ideal and widely used as detector and indicator fluids in leak test procedures.

Galden® PFPE DET, the detector fluid specifically designed for high reliability methods thanks to its perfect balance between low and high boiler components, can easily detect large and small leaks. High boilers enter through large leaks and remain liquid until the test is performed while low boilers can easily penetrate into small leaks.

Galden® PFPE D02 and D03 are low consumption indicator fluids which can be advantageously used as indicator fluids respectively in military and non-military applications thanks to their higher boiling point and lower vapor pressure at test temperatures.
