Homebrew PCBs

For many years I used a carbide tile cutting scribe to score/snap PCBs. 
But with thinner PCBs they bend and distort. So a shear might be better. 
But they do NOT work on FR1 boards which are more rigid and more flat.

I recently switched to this 4" desktop saw for more precision and faster 
'production' type work as I am starting a kit series.

The diamond blade is awesome and the product captures the dust by using 
it in the same box it came in - cut down to access the table.

PCB distortion and dimensional precision is critical when trying to 
build cavity filters etc.
