How does this pass for Quality Control? Solder points are blown out from when they drilled the other holes in the PCB.

SiL3nTOneMaybe I am missing the issue, but my board looks like this, as does a Duck Lightsaver pcb that I am currently using with no issues. I think these "blow outs" are pretty common for boards that support multiple layouts and shouldn't affect your ability to insert and solder switches and LEDs.

FlyingpikeFor the amount of money and the wait time this is not the level of quality that i expected, i'm not worried about crescent moon shaped holes in the bottom of the board. What i am worried about and would not risk is soldering in a crescent moon shaped solder hole and pad that is clearly not supposed to be that way.

SiL3nTOneThey’re supposed to be that way. The images on the description for this drop show them this way. If you look at any plank or preonic build log and you can see the pcbs have holes and pads just like yours. As do almost every other custom keyboard pcbs that support multiple bottom row layouts. I don’t think you need to be worried about any soldering issues. If you are using the standard layout I don’t think you’ll even be using the crescent shaped holes except for LEDs maybe. It isnt a quality issue, it’s by design.

SiL3nTOneThose are by design (and have always existed in our designs) - the lower ones are for the PCB-mounted stabiliser, and they don't affect the ability to solder onto the points. The others are for over switch positions (1.25u and 1.5u keys). Overlapping footprints like this are necessary to pack-in all of the features we'd like :)
