Hi Guy's, Sorry about this, but yes it's another lead free related question. We are looking at using a Chinese SMD DC-DC Converter in a new design, whilst keeping one eye on the approaching Lead-free issue. The manufacturer claims that these are O

Lead-free means expensive tin. Tin is an excellent solvent. So, metal parts in contact with molten tin must be expensive enough to resist that nature of tin. To learn more about this: * Search the fine SMTnet Archives * Look here: "Liquid Tin Corrosi
