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-710 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-710 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 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 VC-710’s are hermetically sealed so an aqueous wash is not an issue.
