CAM software for PCB milling

ProtoLiner Pro

ProtoLiner Pro is a professional CAM package specially developed for the electronics industry. With this package, you can generate contours using data intended for PCB fabrication using chemical processes. These contours are translated into a language understood by milling machines.

ProtoLiner is used worldwide for milling high-quality prototype boards, front panels, and other components used the electronics industry. The program is very easy to use. A wizard guides you through the entire process step by step, from importing the data to generating the toolpaths and producing the machine code. Intelligent contour processes and clever tool use ensure that the produced boards are virtually indistinguishable from chemically etched boards.

Internationally unique

ProtoLiner Pro is one of the most powerful contour generators available. It imports the designs you produce using your favourite drawing package and displays them on the screen. Contouring of the various layers is performed automatically.

No restrictions

Unlike other packages, ProtoLiner can process very complex PCBs, with or without large copper areas. The package can easily read in commonly used file formats, including Gerber, GerberX, and Excellon. Traces and islands can be isolated in various manners. Editing options, step-and-repeat, mirroring, rotation, and many other capabilities are standard features.

CAM station

ProtoLiner is more than just a contour generator: it is actually a sophisticated CAM station. You can fully adapt the imported design. For example, you can modify trace widths or separations and enlarge or shrink islands and holes.

CAD module

You can design simple PCB layouts and front panels directly in ProtoLiner. This capability is highly appreciated for designing HF PCBs. ProtoLiner works with True Type fonts, which gives you potent engraving options.

Design Rule Check

Rigorous design rule checking ensures that your design can be processed, and database management gives you complete control over the tools and parameters. The file that is sent to the machine contains all the information necessary for stand-alone machining. No additional machine settings are necessary.
