PCB CNC: Unterschied zwischen den Versionen

==Introduction==

CNCs can facilitate in the creation of PCBS:

* Manual etching and then using CNC to drill automatically.

Currently, all three steps are working on the [http://metalab.at/wiki/Geil-o-mat Geilomat].

~~[[Bild:nicerpcb.png|thumb|400px|A normal isloated result.]]~~

For the isolation, there is the normal approach, where all contours of copper areas are milled.

However much faster results can be obtained by milling the minimal path necessary to create the PCB-topology.

Some results are given in the soup of the [http://geilomat.soup.io/ Geilomat]

* It is possible to have one wire between the 2.54mm piched pins.

* Also 1.27mm pitch SMD chips are usually ok.

===Time Consumption===

==Time Consumption==

For a complete, dense EuroPCB, expect about one hour of total time:

* 10 minutes for preperation, mounting and setup.
