1) 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.
2) Contact pads are gold over nickel, the maximum solder temp can be lower, e.g. 220C.
Reliability
The VC-715 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-715 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.

VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The VC-715’s are hermetically sealed so an aqueous wash is not an issue. Contact pads
are gold over nickel.
