Hi-Reliability Evacuated Miniature Crystal Oscillator (EMXO)
atm cc/sec He or better. To perform a leak test at this level
presents a challenging task. A Krypton-85 leak detector can
test leak rates down to this level but the bomb duration is very
long and may not be practical for manufacturing.
Contrary to most electronic devices, the EMXO has a
proportionally controlled oven whereby power consumption is
inversely proportional to thermal resistance from the oven to
the case. In this case, the EMXOs vacuum is utilized for
thermal insulation. If the vacuum degrades as a result of a
leak, the power consumption will be much higher. Hence,
electrical parameters such as power consumption and
frequency aging can determine package hermeticity. Please
request Vectron’s EMXO white paper for additional detailed
information on package hermiticity.
