| Subject: | Re: Problems Soldering DB-25 Connectors |
Folks,
Thank you for all of your advice. 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.

Yes . . . the learning curve is rather
steep but it DOES take some practice . . .

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.

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.

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.

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.
