Hi. I am trying to understand Tg and how it relates to reflow. With the higher temperatures of lead free, we have been looking toward laminates with a Tg of 180 instead of the current 140. My question is a little more general. In either lead free

I am looking for public papers or articles on intermetallic formation as a function of reflow profile. Most solder paste vendors specify peak temperature and time above liquidus, but I am particularly interested in what happens to intermetallic grow

Tg is just a way to say when the board goes limp... or a quick way to rank laminates... who cares. For lead free you want to look at Td, Decomposition Temperatures. ( Temp at which the material weight changes by 5% )

=330*C is good advice. Search the fine SMTnet Archives for earlier discussions on Td, like http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=32430
