pcb guillotine blades

[FuzzyParticipant @fuzzy]

I use tin snips to cut PCB without problem. These are old style, straight line cutting only snips. "Aviation" snips do not work.

Picture of tin snips is at http://en.wikipedia.org/wiki/Snips.

If you close the snips completely it will rip the PCB So you have to cut a bit, then move snips forward and cut again.

For longer cuts I use a "plate shear" –

Both the snips and the shear have blades which are parallel to each other. Blades are very flat and snugly oriented toward each other.

Just a thought, how about a tile cutter that would score your PCB for snapping. the type you run back etc on the tile. not that I will ever cut a PCB but do admire the chaps who can take a pile of little electronic bits solder them in and it works.

Guillotine blades are ground to an exponential curve so that they present a constant cutting angle aand the pressure applied will remain constant.. Tomol

Terry,

Sorry forgot to check this thread, forgot I'd posted in it.

The PCB is actually a copy of a board. The original is on the web as a PDF, it's the board for Steve Ward's [ Kwackers ] copy of the Division Master.

The PDF was opened in VCarve pro which will open PDF files, exported as a DXF into my favorite CAD program, cleaned up and then taken back into VCarve pro and processed.

I do it this way as my CAD program, like most CAD programs has more facilites than combined programs like VCarve.

Nothing wrong with VCarve but it's more a CAM package than CAD.

John, Hope its ok to revive such an old thread.

Just wonder if you still make your pcb this way using Vcarve?

Thanks Peter

Surely it must be cheaper to buy the ready made PCB, even buying the complete component package is quite cheap.

Hardly worth the effort, I like making electronics but cost effectiveness has to come into play.
