Can I solder lead-free terminations with leaded solders such as 63/37?
Lead-free terminations such as pure tin, silver palladium and tin bismuth have been in use for years. So they are already being soldered with 63/37 solder without much issue. Today more and more components are coming lead-free, where they may have had a leaded finish before. Some component manufacturers are issuing different part numbers some are not; some companies are notifying distributors and assemblers of the change some are not. For the assembler, even if it is not going to lead-free soldering, it becomes important to know what these new finishes are since solderability may change requiring process optimization to maintain product reliability.
