Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or
any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum
ratings for extended periods may adversely affect device reliability.
Reliability
The VC-501 family is capable of meeting the following qualification tests:
Environmental Compliance
Parameter Conditions
Mechanical Shock MIL-STD-883, Method 2002
Mechanical Vibration MIL-STD-883, Method 2007
Solderability MIL-STD-883, Method 2003
Gross and Fine Leak MIL-STD-883, Method 1014
Resistance to Solvents MIL-STD-883, Method 2015
Handling Precautions
Although ESD protection circuitry has been designed into the VC-501 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.

Recommended Solder Reflow Profile
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 183C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down.
The time above 183C should not exceed 60 seconds and the peak temperature should be no more than 240C
for 10 seconds. The VC-501’s are hermetically sealed so an aqueous wash is not an issue.
