To allow the production of PCB-class feature sizes compatible with a traditional PCB router, the cutting tool was sharpened to a much smaller point than would be used in a lathe using a stone.

Preferring to spend hours typing code instead of graphically pushing traces around in a PCB layout tool, [James Bowman] over at ExCamera Labs has developed CuFlow, a method for routing PCBs in Python.

Secondly, interposer PCB technology addresses signal integrity and power consumption issues. By utilising interposer technology, signal pins can be directly connected to the interposer layer, reducing ...
