Help Soldering. Wick won't suck up solder.
« on: Sun, 06 July 2014, 21:07:57 »
Did I **** up GH? I just bought a Hakko FX-901/P to do the Cherry stabilizer mod to my KUL ES-87, where I would remove the stabilized keys, clip the stabilizers' bottoms, then put it all back together.

But with the tools I have, the Hakko, a soldering wick, and some solder, I cannot remove all of the solder from the joint. I got it to where the solder was flush to the board, but there was solder still around the contact. The wick just did not want to suck up the solder. I had to heat the solder, and then stick the wick in, otherwise nothing would get picked up, I couldn't get the solder to melt underneath the wick, it wouldn't melt. I think it might have something to do with non-lead solder. I think they might have used it? Just because it seemed to have a higher melting point than my new solder.

This really sucks, I've been trying to get it to work all day and now I'm just pissed. I have work tomorrow and no more time to try it this week. ****.

Help me GH. You're my only hope. What do I need to buy to make this work? I've already dumped so much money into this that I'd like to keep it under $50 if possible.  :confused:

The wick might suck, figuratively. It's supposed to contain flux inside it, that should flow out when you heat it up using the iron - the flux is what helps the solder to get sucked, literally, up into the wick. You might also not be getting sufficient amount of heat into the wick - keep in mind that heating up something with some thermal mass like a wick takes up more juice than heating up a small solder joint like a switch pin.

Even with my plug-in Hakko, I hate using wick to remove solder. If it's a through hole, I found that the $15 radio shack desoldering iron with the rubber bulb works wonders for the price. I removed all the switches from a ducky keyboard with it no problem whatsoever.

Do you think a soldapult or solder sucker would do the same job?

Definitely not. It may cost almost as much though.
I have a solder sucker too, and it came highly recommended, but the difference between using a hot tipped sucker like the radio shack desolderer and trying to use a soldapult+iron is night and day. Having that tip in contact with the melted solder makes it so much easier, it vacuums like an absolute champ. Best $15 I've spent when it comes to electronics.  The only thing people complain about are the tips eventually wearing away, but you get replacement tips for like 2 dollars or something, and I've desoldered over 200 throughholes with it and no damage to the tip yet.

I can't agree more. Until recently, I had only used wick, spring loaded solder suckers, and the whack-it method. Wick works, but is super tedious, and it's hard to completely clear a through-hole with it. Solder suckers, in my experience, are almost universally terrible. For my last mod, panda clears on a poker II, I decided to try a desoldering iron with a bulb on it. It works wonders. I did burn a hole in one of the tips, but it was worth it. I did the entire board in a fraction of the time it would have taken with any other desoldering method.

Wick isn't ideal in my opinion. Like Parak said, you have to heat the flux in the wick as well as the joint. I much prefer my Soldapult.

YAY! The soldapult worked so much better, I was able to get the key off today! Now on to the clipped stabs mod!
