      The device is qualified to meet the JEDEC standard for
      Pb-Free assembly. The temperatures and time
      intervals listed are based on the Pb-Free small body
      requirements. The VS-720 device is hermetically
      sealed so an aqueous wash is not an issue.

      Reliability
      VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
      IR reflow simulation. The VS-720 family is capable of meeting the following qualification tests:
      Environmental Compliance
      Parameter
      Conditions
      Mechanical Shock
      MIL-STD-883, Method 2002
      Mechanical Vibration

      Solderability
      MIL-STD-883, Method 2003
      Gross and Fine Leak
      MIL-STD-883, Method 1014
      Resistance to Solvents
      MIL-STD-883, Method 2016
      Handling Precautions
      Although ESD protection circuitry has been designed into the VS-720 proper precautions should be taken when
      handling and mounting. VI employs a human body model (HBM) and a Man Man method (MM) for ESD
      susceptibility testing and design protection evaluation.
