I find removing surface mount resistors, at least on the underside of the K3 main board, quite simple. It's easier than removing wire ended resistors from plated through holes! Remove the bulk of the solder from each end of the component with solder wick, the heat from the iron will often have migrated through the component by this time and it will slide away from the pads, if not dab the other end. I really do not like cutting surface mount resistors and capacitors with side cutters as a means of removing them.
Getting the replacement component nice and square on the board is harder than removing the old one as the heat from soldering the second end can be enough to cause the component to shift slightly. 73 Dave, G4AON K3/100 #80 with all the published mods. ---------------------------- Ian GM3SEK wrote: >/It's an easy mod.
