De-soldered Parentheses Fuzz PCB - Is this OK to redo?

[PoppaAdat]

I just stripped a Parentheses Fuzz PCB that was my first ever DIY pedal project. I had gotten about halfway through a very shoddy job of it before realizing I didn't have all the parts (and probably using some parts of questionable quality) so I put it aside. Now after a few successful pedals and being much better as soldering, I decided to strip it and start over. My question is in stripping it, I seem to have slightly removed the black covering in a few areas as well as burned a few areas around the pin holes. Will any of that be a problem? I was concerned about the metal underneath the black layer coming into contact with a solder joint and potentially sending that area to ground.

For the burned hole areas, I am assuming I can take a fine file to that area and try to get down to unburnt metal if it matters.

I tried to point out the areas I am referring to in the second pic. That pic especially show where I scraped away too much down to the metal underneath.

I already cleaned off both sides with isopropyl alcohol.




Any help is greatly appreciated!

If you have a multimeter, you could check the connections for the points in question.

Look at the schematic and check that those points are connected to another correct point.

For some of them, you can see the trace on the board. So you can easily check the endpoints of the trace.

I’ll add: I’ve messed up a board that looked much worse and it was OK. So I would be optimistic, but I would check it before repopulating it.

These are the pads that I suspect might be more problematic. It looks like the pads have been lifted, which although not a deal-breaker, is definitely an area for possible complications if you aren't at least somewhat familiar with repairing damaged pads/traces.

The Parentheses isn't the easiest build here, has quite a few components, and takes no prisoners... it's Christmas, how about I just send you another PCB?

Yes! Proactively stopping threads in the troubleshooting area! BTW very kind!

Let’s keep idea rolling! What parts are you missing?

Oh WOW you are too kind! If you think that is the best course of action here, then I humbly accept your amazing offer! I think I have the soldering skills now and would hate to go through all that work just to find out I messed up the PCB. If you want, I can even send you this PCB so someone more experienced than myself can hopefully salvage it. I can DM you with my address..it has changed since I originally purchased this over a year ago.

I actually have already acquired all the parts for the rework and even have a sweet printed enclosure ready to go! Well at least I THINK I have all the parts until I go to assemble everything and figure out I am missing a single resistor or something

Well let me know if it I have it I will send it!

If this was a simpler PCB I'd say go for it, it's not rocket surgery and is definitely a good skill to have under your belt.... The Parentheses, though, seems to be tricky enough for a lot of folks even when the PCB is in perfect condition.

Thank you so much for the offer! I'll let you know if I missed anything. You all are so kind here!!!

Desoldering PCBs has been a dreaded task for me. I need to get one of these so I can look forward to my screw ups.

Maybe you can put one on your Christmas list too.

For sure, I used about 4 of the plastic blue suction pens and kept having to rotate them in and empty them as I moved along. And I used my first ever soldering iron that I got from Amazon to de-solder thinking I could save use on my nice Hakko station. But I should have stayed with my Hakko bc that crappy iron couldn't maintain a consistent temp. Live and learn.

Correct me if I'm wrong but doesn't it seem like everyone who posts about it says they put the rotary on backwards at first I know I sure did.

Oh god I never got that far on my first attempt but I didn't know you could install it backwards. You don't mean upside down though, do you?

Yeah that's what I mean!

 

[PoppaAdat]

Ya know, I can see why people would make that mistake. It feels different somehow than the normal pots, like it would seem to go on in the same process as all the other parts.
