Well. I had a few last night. Decided to finish my multiplex board. I completely ignored the "slow down and pay attention" note. (http://tapatalk.imageshack.com/v2/15/01/22/aefcca5e34117fc94e5472d1abfc1fc4.jpg)
So. I'm having a hell of a time desoldering the rotary. Used a sucker. Braid, etc. I just cant seem to get it all. Think a heat gun might work to loosen all the solder remnants? I need to test all the pass after I cut the leads flush to make it easier but still can't get it.
Ugh. The more I drink the more I have reasons to drink. Lol.
What's wrong with the rotary? I wouldn't think you would be able to orient it incorrectly though I guess the modes would be in a different order maybe?

wrong side of the board. lol
Completely missed the obvious here... yeah I did the same thing with my danger zone build and the 2pdt switches. My solution... free floating pots instead of board mounted.
Been there, done that for sure.
Here is what I do.
My desoldiering game stepped up when I bought this
http://www.adafruit.com/products/1597 (http://www.adafruit.com/products/1597)
What I do is add a little bit of fresh soldier on the pad and heat up the pad for a second then get the silicon tip of the pump on the pad to create a suction and BAM a clean/soldier free hole.
There are better ways I am sure with a desolidering iron and what not but this is the cheapest route that gave me good results. Hope this helps.

dang i just paid way more than that for one of those engineer solder suckers on ebay. like 30 bucks. :(
I've had to do massive desoldering projects on several occasions due to similar attention to detail :(. What works for me is desolder each pin as best I can (usually with my soldering iron and a sucker). Then heat & pry (using a probe) one pin to get a little gap from the board, then move to the next pin. Repeat until the switch is free, sometimes I make a couple of laps around the switch. It's slow and frustrating, but it has worked for me several many times.

They actually came down some recently. I paid $20 from Adafruit last year.
I did find that after a few months of use you will need to oil it. I was a little frustrated with it a few weeks ago since the suction was sub par and it was to slow retracting to suck up anything. The really cool think about this thing is it is dismantleable (is that a word) easily. I used some electronic cleaner/lube spray and it now acts like new.
Cody
Thanks all. I need the encouragement. I thought about just mounting it straight up and not worrying about the pots being pcb mounted. but I honestly just want a clean pcb mounted solution. So much easier for me.
I used my radioshack solder pump first, similar to those ones. I have a desoldering iron too, the radioshack one and i'm going to go to RS at lunch and grab a new tip. I couldnt seem to get it hot enough, but the tip was dirty dirty dirty.
I tried the one at a time and prying and just couldnt get it to move at all. with the 16 or so pins, it just didnt want to budge at all.
Worst case scenario I'll mount it upside down and hopefully the switching is just a little reversed. I may need to redo some of the caps though or shim the switch a little bit.
Thanks again.

good to know. i still haven't received mine, expecting it any day now. and dismantleable works for me ;)

With shipping it ended up being like $27 if it makes you feel any better.
If you want to salvage it you can send it to me and I'll desolder it for you and send it back.

Thanks Josh. I just might do that. I'll give it one last hurrah tonight, sober, to see if I cant get it out. Can you PM me your address just in case ? I'd appreciate it very much.

Indeed it is.
I decided to just send it back to Josh. I'm not going to try messing with it. I'm sure I've done enough damage as-is. Plus it gives me an excuse to order more PCBs from him (not that I needed one).
This is the one build out of my 20 or so I have going right now, that I couldn't wait to get done. I've had the board for about a year now and just got back in it since I had to move all my gear out to my garage to make way for baby #2. My office/music room is now (or will be) a nursery.
Thanks again Josh!

I grabbed one from Adafruit as well.
My main beef with it is that the clearing rod should be longer so that it can fully push out the solder that sticks in the flexible tube. I have to take off the silicon tube frequently to clean it out. It's possible the tube is cut too long, but this is the stock cut length as it arrived on the solder sucker. I can cut the tube down, but I kind of like it at its current length.
cody and i just bought 5 feet of high temp silicon tubing for replacement nozzles, so maybe one of us will experiment with different lengths.
if you want i can send you some when i receive it, dave.

I do agree with you on the soldier getting stuck but it was not a deal breaker for me since the suction was really good and the seal you can make with the tip on pads. We can definitely try some different lengths of the tubing and see if that helps at all.
I wonder if we send them some emails and see if there could be an updated model with a longer extraction pin.

I just got my ss-02 today. It looks cool. Way higher quality and smaller than I expected

I did that with a Rissole board. Well. Not just "that."
Not one rotary.
FOUR damn rotaries.
I briefly considered trying to desolder, for two heartbeats, then gave up and got another board out. Luckily, I socketed the LED/LDR pairs on that board.
For the time/money cost, I'd rather just get another board, if possible. Passive components are cheap. Admittedly, I had nineteen other Rissole boards at the time :P
I gave up and bought a desoldering soldering station and my life has changed.. $149.00

buy this and use it...
I get frustrated and hit it with compressed air after the solder sucker. A little preventative tape and the vaporized solder should clean up with a toothbrush. But a de-soldering station? I likes the sound of that. I'm constantly finding new ways to solder stuff the wrong way. :-\
Another thing to try, if you can get cutters in, is to clip the switch pins between the body and the PCB..... Then the pins can be de-soldered individually.
I know it means that the rotary switch will be non-useable, but it saves in other areas like self-loathing, frustration and extreme perspiration...... :-[
Sometimes its easier to cut your losses and buy a new part.

I did that exact thing with my multiplex
Luckily I was able to use one of those solder iron pump sucker and was able to get it off.
I have three different lovetone pedals I am about to build and I am praying I don't do that crap again.
I did the same with a SHO NUFF. put the stomp switch on the wrong side. I had it sitting around for months and one night I picked it up and and noticed it was wrong...I have a desoldering station and it was still a PITA to get it off. I destroyed the switch but hopefully the board is still OK.. Those are the kinds of lessons you don't forget, hopefully..
