PCB Drilling Platen: Wear and Tear Thereof

This PCB will become a brassboard for a blinky light using Hall effect current sensing:

Most of the components are in SMD packages, so it’s tough to wire a complete test circuit without making a PCB.

The maximum-size PCB drill platen is getting chewed up, although it’s nowhere near end-of-life:

But I’m thinking about a vacuum table…

    I use clear pine as my spoil board, and do a lot of milling on it. It doesn’t take long before there’s only a sort of vague impression of a flat surface, It’s reminiscent of Utah, with lots of small lumps of material all rising up to the same high point, so possibly there’s _some_ support there. I go through one every six months.

      The other scraps of plastic I use for sacrificial plates and mounts look even more shot up. This one is special!

      I figure if I start thinking about a vacuum table now, maybe it’ll be close to ready by the time I desperately need the thing…
