Live and Learn

My first attempt at salt and vinegar etching a PCB turned out to be a bust. I left the fabric in the solution for almost 24 hours instead of the recommended 12; this disintegrated the traces and lost all the connectivity. I am in the middle of a second attempt at the moment.

Two lessons to take:

  • Do not leave the fabric in the bath for more than 14 hours.
  • Make sure to completely submerge the fabric.
  • Leave a comment
