I'm sure this has been discussed before, but I can't find any info on it currently. The piclist.com search page has been giving me odd results on this (some results found, but not readable due to errors or missing info). And Google has pointed me to some conflicting info, and some open questions. In a nutshell, I am trying to understand what should be done about the lead-free mandate / Rohs-compliance? First, there are clear statements that this is a mandate in Europe for July 1, 2006. But I've not clearly seen that it is a mandate in the US for the same date. Is it? For compliance, is it a simple matter of making sure that all components, PCB, connectors, wires, etc are compliant, and soldering with a lead-free solder? I found a number of alternate solder choices, but don't have a clear understanding of what the properties are or how the properties compare to generic tin/lead solder. Is there a preferred solder substitue for the average user? I assume there is no simple drop-in replacement? What about tools -- how will this affect the soldering equipment used? Obviously if melting temps change, then the soldering iron temps will need to change. Is there any certification/testing of products that will need to be done to claim that end products are compliant? Anything else?
