Whisker Analysis


Hello ,

I have a design which uses the AD7928WBRUZ and need package information to do a Tin Whisker Analysis.

Can I get information such as:

   # Lead Finish Material

  #  Process (Electroplate, Immersion, Hot Dip)

   # Material Directly Beneath (brass, Cu, Fi, Ni, other)

  #  Substrate Controlling CTE (Ceramic, Low Expansion Alloy, Cu, Al, Fi, other)

  #  Is plating heated after deposition (No, Annealed, Fused)

Thank You!

    If you navigate to the product page for the AD7928, under design resources, you will find a link to the materials declaration form for this particular package which I believe contains all the information you require with regards to materials.   In terms of processing steps I will inquire as to where this information might be accessed and get back to you.
