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.
Thank you for your feedback , I already found the shared informations MDC , but it is not fully sufficient for our whisker assessment .
I am still waiting for your answers regarding the requested data , and also if you can confirm the Sn type (Matt / Bright ) .
Thank you for your support .
