Isolation Routing PCBs

[cropwell]

This was my yesterday project ---


and I briefly mentioned it in another thread.

Doddy - I cut the PCB with a 1mm single flute mill to drill the holes and clear the bulk of the copper, then tidied up the tracks with an engraving cutter, DOC 0.2mm.

The circuit was designed by an adaptation of one I found on t'Interweb. It is a logic indicator (Hi-Lo-Pulse) which used a 4001 quad NOR gate. I rejigged it to use a 4011 quad NAND gate as I could find some of those (I have probably also got a tube of 4001's somewhere in my entropy driven storage area).

The circuit was drawn up using Circuit Wizard (which is old and has a very basic component library) and that produced the circuit board and output Gerber and Drilling files.



I then used CopperCAM to build a dxf from the Gerbers and then I put the dxf through the CAM process to give Gcode.

This was all a small run as I want to do a larger board for my next(ish) project, but I will be starting with KiCAD for the circuit design.
