Last night, I did some more experimenting and achieved much better results. My solder-sucker doesn't completely clean out the old solder from the cups so I will try some solder wick tomorrow (no time tonight). I got most of the solder out, trimmed a few conductors from the wire, and was able to neatly and securing solder 20 AWG wires to pins. It was quick and I have connections that look safe and secure. In case you are curious, unless the solder wick works miracles, I will discard the DB-25 connectors that I have "messed up" and start from scratch. I am not driven by any irrational *need* to salvage these things. What I thought would be a simple assembly process has turned into a great learning exercise. I'll let you know how things go later this weekend. Cheers, -- Art Z. -- http://CheerfulCurmudgeon.com/ *"If I am not for myself, who is for me? And if I am only for myself, what am I?

Yes . . . the learning curve is rather steep but it DOES take some practice . . . > My solder-sucker doesn't completely clean out > the old solder from the cups so I will try some > solder wick tomorrow (no time tonight). I have solder-sukers . . . VERY SELDOM used except to open a plated through hole in a circuit board. Really most effective when powered by vacuum pump pulling on a heated tip attached to the end of a soldering iron. > I got most of the solder out, trimmed a few > conductors from the wire, and was able to > neatly and securing solder 20 AWG wires to > pins. It was quick and I have connections that look safe and secure. Good for you. Solder wick can be VERY effective but there are some pot-holes. The wicking needs to be FINE and impregnated with a good dry flus. There are many good ones and many more poor ones. >In case you are curious, unless the solder wick >works miracles, I will discard the DB-25 >connectors that I have "messed up" and start >from scratch. I am not driven by any irrational need=C2 to salvage these things. Try heating a solder cup then rapping the connector on the workbench to shake out the molten solder. I would hold the connector in a pair of pliers by the end-tab, heat the solder cup then 'whack' the piers on the bench with solder cup facing down. You'll find it is quite clean. >What I thought would be a simple assembly >process has turned into a great learning exercise. My 'lifetime supply' of Chemtronics wick is holding up well so I'm out of school on current offerings. I'll order some samples of current offerings on 'solder wick' off eBay. It's a whole new bunch of players since I ordered any.
