Thanks so far for the civil and positive responses, it's a reminder that the community isn't always a mess like it can appear in some current, unspecified GB threads. I've not heard back from the seller yet and am planning to send another email later today, but I'll address some of the comments so far:
- On all the PCBs I've inspected so far, they do connect to BMC, the firmware flashes successfully, and random switch tests work fine, so for the most part any of the damage does seem just visual.
- I am planning more comprehensive testing of boards that do have potentially performance-affecting damage, ie the port scrapes crossing the LED trace for LCtrl. I would prefer to not send out boards with this particular issue at all, but I might not have enough boards that don't have it, so at the very least I will be testing it and making any necessary touchups to it to make sure that LED is still functional, which should just be making sure the copper from the ground plane isn't in contact with the trace and covering the bare copper with something to keep shorting from being an issue.
- In the same way, any other scratches I find that look to be deeper than just the surface of the mask I'll be doing comprehensive testing of any portion of the matrices that they cross to determine if they're an issue. So far I think I've only seen maybe one that even reaches the copper other than the port scrapes.
- Most of them I will be scrubbing scratches/scrapes/residue spots with ISO to try and get rid of as much as I can of what's just visual, so I'm hoping that most will look better than they do now.
Even if I can't guarantee that the top of the PCB will be spotless, I will be guaranteeing that everyone does end up with boards that are 100% functional, or at the very least compensation for any lack of functionality for which I'm hoping that contacting the seller will provide me with even if they're functional.
I do want to point out that I only realized earlier today while going through some of the boards that none of them appear to actually have numlock or capslock leds soldered onto them, which is more disappointing when I have a conversation with the seller specifically about using white instead of green for this. If that's going to be a problem for you let me know and I'll see what I can do about it, even if it means buying some and doing some SMD soldering that I told myself I'd never do again.
I want to thank you again for keeping the thread civil and positive as it's a lot easier on me to deal with than the negativity that I see pop up way too often on some GBs that have some hiccups. It's been a tough year for me and my projects and I don't know where I'd be right now without the understanding and positivity of those that have been willing to support me through the difficulties.
