VS-500 Voltage Controlled SAW Oscillator
Reliability
The VS-500 family is capable of meeting the following qualification tests:
Environmental Compliance
Parameter
Mechanical Shock
Mechanical Vibration
Solderability
Gross and Fine Leak
Resistance to Solvents
Conditions
MIL-STD-883, Method 2002
MIL-STD-883, Method 2007
MIL-STD-883, Method 2003
MIL-STD-883, Method 1014
MIL-STD-883, Method 2016
Handling Precautions
Although ESD protection circuitry has been designed into the VS-500 proper precautions should be taken when
handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD
susceptibility testing and design protection evaluation.

Time (s)
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR
reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to the
profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux
is activated, a ramp up to 183°C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The
time above 183°C should not exceed 60 seconds and the peak temperature should be no more than 220°C for 10
seconds. The VS-500’s are hermetically sealed so an aqueous wash is not an issue.
