I’m now picturing a stoic Scotsman with a soldering iron suddenly slapping a board on the table with ninja-like speed, then carrying on soldering like nothing had happened. ---

I listed some options earlier in this thread: > [@A litany of dumbassery](https://lookmumnocomputer.discourse.group/t/a-litany-of-dumbassery/526/108): > > Some options: Wick + extra flux (get a flux pen, and add extra flux to the wick before wicking) Manual desoldering pump (varying quality, most are a bit crap, I have an Engineer brand one that’s supposedly good but haven’t tried it yet, but even the crap ones can be useful for a first pass). Toothpicks, as mentioned (I think it was @analogoutput who [first suggested that](https://lookmumnocomputer.discourse.group/t/1113-performance-filter/14/9)) [Desoldering needles](https://lookmumnocomputer.discourse.group/t/1113-performance-filter/14/10) may work in some cases; less likely if the holes are tiny. Inertia – heat up the solder, smack the boar… ---

> [@twinturbo](#): > > them So far so good. They were what I had on hand when I started, and are cheap. I can see them failing at some point, but are cheap and easy to replace when/if they do. For my diy non-PCs modules they’ve been working great so far. If I was performing professionally I probably wouldn’t use them. But as a hobbyist…I’m fine with them. ---

I’ve been a lot more relaxed about needing to desolder since I got the Engineer solder sucker. ---

That will work for one pad, but I really advocate for braid on hand in case you need to clean something like a chip header. Those are practically impossible without some braid to suck it up, and it’s bound to happen at some point. ---

The braid is my savior. ---

I hated braid…until I tried the MG Super Wick. That stuff is like magic. Now I prefer braid over the sucker in most situations. The other trick is using the right size braid. The “yellow” #442 works best for me on most things…but I also keep the larger green #425 on hand for larger components. ---

I after many attempts for messing up clearances. Tend too make a position template out of a bit of plywood for placement then position it is place clamp it down and drill. Then after I completed it I use the aluminum for a template if I am making more then one. ![IMG_20200302_235919_308](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/1/13cb5d27eaa9c860c98efec77dfca734e28103c1.jpeg) When you need too make it very tight. 🤣 this is my mixer module ---

When you discover that, like a complete rookie, you got a variable resistor connected backwards on your PCB layout, you can toss out your module and try again, sacrificing eight [9mm B100ks](https://lookmumnocomputer.discourse.group/t/9-mm-pcb-mount-vertical-pots/1732) in the process, or you can bodge. ![PXL_20201104_172333982](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/2/298688ceaf00f8039046f8ca95afd3f9a8ba7b09.jpeg) ---
