I did the first one at my bench, and while I had a solder sucker available to me, I didn't use it. I simply used some de-soldering braid. First I removed the old F2 part, then completely filled the holes with new solder and finally used the solder-wick to remove all the solder. Works like a champ. Did this for the inductor as well. The SMD part is a little trickier, and I'm no spring chicken either. The first thing you need is a really good magnifier, I prefer the goofy looking visor style. To remove the old diode, I simply heat up one side with the iron and flick it up so it is only held by the other pad, then remove it completely. I next use the solder-wick to completely clean the pads and then apply a very, very small amount of solder to one of the pads. Holding the new part with tweezers I place it on the pads and tap the soldering iron to the pad that has a little solder, then solder the other side and come back and clean up the first side. The trick is to use a very small amount of solder. If there is a blob on either end, you've used too much and can use some solder-wick to clean it up.
Ron did a great job on the instructions. As he suggests, just take your time. If a software engineer can do one, anyone can. -Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-12VDC-OUT-current-modification-tp7557906p7557942.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
