Subject: PCB drilling vacuum table ??

From: "designer_craig" <cs6061@...>

I am about to build a vacuum table to hole down the blank stock when I cnc drill my boards. I am looking some low cost sacrificial material to use between the board and the vacuum table.

The material needs to be thick enough so as not to drill into the vacuum table and be some what porous to allow air diffusion for a good vacuum grip.

The ideal material would be something like 1/16" thick MDF. I have heard MDF is fairly porous. I have only seen MDF in 1/2 and 3/4" thickness. Possilble some sort of construciton paper or cardboard. Guess I need to do some experiments.

Anyone got and good ideas?
