ok so I've got a brass sponge- the Aoyue 937+ Digital Soldering Station (figured mid range would be more then enough)- and some Miniatronics Corp 1064004 Rosin Core Solder 60/40 4oz- looks like its .03mm (is that an appropriate size?) Some "helping hands- and magnifier" in my cart. Do i need any smaller- speciality tips for the soldering iron- for the tiny tiny boards that I'm going to be working with?
