You know, this is EXACTLY why you don't let a metallurgist near chemicals.
Not a single one of them passed first year chemistry.
Everyone knows that IC is calculated in cubic slugs per newton-moles. Bev,
back me up on this.

Re: [TN] Solder Data Question
Hi Inge - yep, I try to use the SI system as much as possible, if for no
other reason than to confuse Doug - he was trying to measure some IC
results in fortnights per stone last week! And I was being lazy on the
density as I figured the value existed without me having to do the
calculation. Technet has produced 2 values for me so I appreciate
everyone's assistance.

Re: [TN] Solder Data Question
Dave,
Mike Fenner has a great super solder map from his Indium time. If he does
not answer, I'll look in my pile, but it will take time. You use kg/m3 !
Are you really a american?
You can calculate yourself:
1/q = Ftin/Qtin + Flead/Qlead
in wich F is the mass fraction and Q is the density of the respective
elements
For more elements, just add :
1/Qalloy = Felement1/Qelement1 + Felement2/Qelement2 + etc
all must be in solid state at +20C

Hi folks - does anyone have the density value (kg/m3) for SAC305 at 245C?
