@chemica_tan It depends on the route of production. Classic industrial methods from propylene oxide yield the race mate, while fermentation or bio processes give you the S enantiomer.
@hieywieyneue “Form single lane” is a good way to show that neither lane has priority. If it is not one lane merging into the other but two lanes forming one, then neither lane is entitled.
@SnazzyLabs I had this exact issue last issue with a different brand. There are a few companies out there that do PCB repair for ~$160. Wasn’t worth it for me though.
