Simple two pole devices don't need much engineering to remove, but I would caution against the cut in half with sharp cutters method as it can lead to damaged pads. I can't be bothered creating special tools for two pole devices, just a quick flip with a pair of soldering irons, then use a bit

Dave, Their video showing surface-mount soldering techniques is double-recorded in the audio channel. Pretty frustrating. Do you know someone there you can tell? --Oliver W6ODJ On 2 Feb 2010, at 3:42 AM, David Lankshear wrote: Simple two pole devices don't need much engineering to remove,

It's a process, it's easier than you think, and there is plenty of room for creativity. I don't pretend to know it all; this works for me. BASICS: Light up the work area. Get comfortable seating. Buy a pull-down magnifier. Don't skimp here. I use OPTI-VISOR, 3X lenses. Buy 2 of the

I find that the key to removing SMT components like those involved in the mods described is best done with solder-wick and quick movement of one small-tipped iron to both ends of the component. I removed most of the solder with the solder-wick and then alternate heating of both ends of the

Bob, I have been successful using that technique, but when there is any difficulty with the solder re-attaching, I slide a THIN knife blade under the first side when the solder melts. The blade must be thin (and must have a sharp edge) so the amount of lift is very small - a thick blade

We've got a tech who is amazing with a soldering iron. He has two very nice soldering irons on the bench next to him at all times. All this guy does is work magic with a soldering iron all day long... His two irons are one with a bit of a cup in the end of the tip (for holding solder) and the
