I am trying to compile a lead free soldering defect reference source if any one is doing trials. I would like to swap defect stories and photos. Look forward to hearing from any one.

Dave, It could be more than the size of the article. We are looking into it. We have emailed the contributor of "Lead Free Solder ... ", who is a frequent visitor to the site. Hopefully we will hear from him and know what went wrong soon. Thanks
