Julien, I heard from someone that a solder iron tweezer was good. Two separate solder tips will not work. The part is and the land pads are too small. Exactly what process a person would use I do not know. For instance, would it work to be putting solder down, placing the part and remelting, or putting solder on one pad then heating and placing the part and filling in the other pad. It is tough to rework 0402's and 0201's because both the part size and the layout that is recommended now adays. If you are working on a RF circuit there is evidence, though acceptable per IPC specs, that flux residue and the reworked solder joint will "detune" the assembly. I have been trying to figure out how to remove/wick/suck solder off these tiny land pads that are so closely spaced and not take the pad too. Is there equipment that can doo this delicate process or will boards have to be tossed each time?
