Currently trying to desolder a Pok3r, but I'm having a problem getting all the solder off the switches. The pump I'm using seems pretty good, so the only thing I can think of is that maybe my iron isn't hot enough to get to all the solder melted. I'm using exactly the suggested technique form instructional videos, but for some reason a small amount of solder always remains in the holes no matter how much I try to suck it out. Does anyone have any ideas as to what I can do to fix this?

It sounds like your temp isn't high enough if you're confident that your Soldapult is working correctly..
I usually turn my iron up 50 degrees (F) when I de-solder, also goes faster. How long does it take for the solder to melt when you hold the tip to the solder/pad?
-
I'm not sure which videos you have watched but I suggest looking up the eevblog on YouTube, he's great. Also, try adding new solder to the joint before you desolder it.

It may sound counterintuitive, but adding a small amount of solder back to the joint may help you get it desoldered.
Agreed. Should've read that newport.

Yes I know to do that, some of it's coming out just not all of it.

If you're having the problem on a lot of contacts then something else isn't right, in my experience I typically almost never have to add solder if my Soldapult and temps are right.
If you have to add solder on 2-3 pads, that's reasonable but not on every contact.

You might have to clean the internals of your soldapullt.
Overtime, the solder accumulates inside and the "sucking" power of it isn't that strong anymore.
You can try by pressing the plunger down and using your thumb or finger to block the tip.
If you release it and the plunge moves, it means there's a lot of stuff accumulated inside.
No harm trying though. :)

I had the exact same problem (https://geekhack.org/index.php?topic=72510.msg1768718#msg1768718) with my Ergodox. This video solved it for me. (https://www.youtube.com/watch?v=Z38WsZFmq8E).
Also,
(A) keep your tip tinned
(B) always put a tiny drop of solder on the tip of your iron before putting the tip to the soldered joint (it helps the tip melt all of the existing solder better)
(C) make sure you've got suction. I had to switch from one of those crappy little $6 solder suckers to a soldapult, which has more than enough suction power.

Unfortunately I don't think the tip of this iron is ever going to be tinned again, but I'll definitely give this video a try, thanks a ton!

Oh and frequently wipe off the tip on a wet sponge. Most of the time you don't even need tinner.

I do my best... this one might be beyond repair though. Still tends to work okay luckily. I've never had a problem until now, and it hasn't gotten dramatically worse recently.
