There is only one tin/lead ratio that is eutectic. Sn60/Pb40 is not eutectic.

In both cases you will be close to the eutectic composition(61.9%Sn), so I expect joint to be intact and uniform.

Lead and tin form a eutectic solution. So no to that one, as to breaking some rule or other other people who are far more knowledgeable than me on "the rules" could pipe in. Also tin/lead eutectics don't grow tin whiskers like a lot of the replacemen

Rob We agree with Jason's point about swab lead indicators. You need to be careful interpreting the results. Lead must be in sufficient measurable quantities as found in Sn 63/37 or Sn 60/40 solders. Handheld units are: * Oxford (bought the X-Met
