Hi guys... I've been doing some Immersion White Tin research and was given a link to a technical resource...thought I would pass it on. http://www.floridacirtech.com/pdfs/omikronmarket.pdf http://www.floridacirtech.com/pdfs/omikrontest.pdf If you haven't read these two .pdf files... I would recommend them to you highly...Gives technical test results from Florida CirTech and Parlex and Trace Labs.... and details of their sales pitch.... :) Good reading... and informative. It even discusses Lead Free and compares Immersion Tin, NI/AU, Silver, HASL and OSP....ionic contamination levels, accelerated thermal stress testing, rework, tin depletion with temp and time, finish wetting, electromigration and dendritic growth...
