A printed circuit board starts as an idea that is captured in schematics and PCB layout files for manufacturing. Through manufacturing, a milling machine moves router bits across unnecessary copper for removal, leaving clean, copper areas for installation of components.

Phase 3 – Etch the PCB with the Milling Machine The designer must understand some of the tools and machining process to ensure the proper conditions for milling a PCB out of bare copper clad. The milling machine etches away the copper as instructed by the artwork files and results in a nicely made single- or double-sided PCB.

These circuit board blanks are made by bonding a thin layer of 1 ounce of copper over one or both sides of the entire substrate. To etch a circuit design into the material, unwanted copper can be removed using a CNC machine, leaving only traces. Free software like Eagle CAD, a vector based 2D program like Inkscape or a 2D raster program like gimp will work for designing …

The basic function of PCB milling machines is to selectively mill away a copper layer on the circuit board substrate to form traces and other conductive areas on the surface of the board. Some of these specialized machines also have the ability to form vias.

Carbide Copper will open Gerber RS247X format files and Excellon drill files. Every program outputs a slightly different version of the file so it's conceivable that it will not work with all PCB software. We've tested it with Eagle extensively and are committed to making it work with all popular PCB software.

PCB Milling1. PCB milling is the process of removing areas of copper from a sheet of printed circuit board material. Creating pads, structures, and signal traces should be done depending on the digital circuit board. PCB milling process allows materials to be removed to help make an electrical Isolation and the required ground planes.

PCB profiling involves either milling or v-scoring or the combination of both mechanical techniques. Milling, also referred to Routing, which is performed on a CNC mechanical machine with a routing tool.Routing is used to form the contours and breakouts of the PCB at the end of PCB manufacturing process when separate the individual PCBs from the production panel.

Copper thickness While features as small as 0.1mm are possible, the average CNC user can expect a trace width of 0.3mm with a clearance of 0.3mm. Making PCBs using a CNC has advantages over most other processes; most of the process is automated, and it allows for accurate drilling.

Milling a Copper PCB. How to mill a circuit board: UPDATE: Check out my page on etching PCB's instead, it's much better! From schematic to copper board, getting it done. Note: This page is now *really* old, dating from about 2005. In the interim, I may have lost the images. I'll try to post them again, but it will probably take a while.

It's also quicker to make a PCB with a CNC, despite the length of time needed to make the PCB itself, because fewer steps are needed to turn a piece of copper clad into the finished product. Another massive advantage of CNCs is that the machine can be made to do other jobs besides making PCBs, including woodworking and metalworking.
