We will buy single boards, not panels, so we can easily separate the little fixturing wings after pick-and-place. The PCB house won't brickwall boards on their panel because they route them apart. We slice the v-scores on our big pizza cutter, not bend and snap. -- Father Brown's figure remained quite dark and still; but in that instant he had lost his head.

It could give me a smooth edge for the monitor connector, but that's only 1 GHz so doesn't care much. -- Father Brown's figure remained quite dark and still; but in that instant he had lost his head.

Resequenced and ready to go. https://www.dropbox.com/s/pz6tszau9lsi403/T502A8.jpg?raw=1 I converted the v-scores (with great effort) to slots, and then manufacturing made me make them back into v-scores. -- If a man will begin with certainties, he shall end with doubts, but if he will be content to begin with doubts he shall end in certainties.
