Hi Rex - no, this isn't a Weekly Quiz question but that did give me a chuckle to start the day! I am working on the revision of the IPC JSTD 002 Solderability specification and need that density value for SAC305 solder as part of the specification test methods. Bev Christian and Graham Naisbitt have found the values for Sn63 and Sn60 for me but I/we am still in search of the SAC305 number. I do need the value to be accurate - where did ya find the 7280 value?

I assume this isn't a Wednesday Quiz? From what I've found on the web, I'd say/guess about 7280 kg/m3 How accurate do you need to know the answer?
