Dave, When we converted the Humiseal thermal conductivity info into W/m-*C we came up with .167 - .209. Did we do somthing wrong with our conversion?

I heard that Swatch was granted their exemption to use lead solder for anything under 800 microns pitch. Is this true? Can't find a thing on the Web stating that this exemption was granted. Chris

I wonder if you could push this to exempt any board with SnPb paste applied to the entire board as long as it has fine pitch parts? hmmmmmmmmmmmmm

James, Smart thinking!! That�s what Swatch and probably Sony does. And to set the record straight Japan doesn�t have a lead ban in solders only a recycling program similar to the European WEEE

I would hope that the committee is at least intelligent enough to insist that exemptions be based on the use of parts w/o coarse pitch equivalents, but we are somewhat evidence challenged in that respect.

Am I missing something, or does this exemption only apply to lead finishes? That's the way it appears in the referenced section, anyway. How does that exempt them from Pb-free processing?
