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?

Dave

RE: [TN] Solder Data Question






I don't know as I've hunted on the web and cannot find a fact I'd trust.
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?

Regards
Rex

Hi folks - does anyone have the density value (kg/m3) for SAC305 at
