The circuit board router allows lab users to prototype single or double layer circuit boards. The LPKF ProtoMat S63 drills holes and cuts insulation paths from a full sheet of single- or double-sided copper clad material, leaving behind the traces, pads, vias and pin holes for components to be attached. Because this is a subtractive machining process, designs should try to minimize the amount of copper removed, not the amount remaining on the final board.
Important Note: Because this is a labor-intensive machine run by student workers, and the board costs are fully subsidized by the Sears Circuits Lab, we are currently only able to offer this service as a prototyping service, for a maximum of two boards. Also we are only able to offer this to actively enrolled undergraduate students at local universities who are working on non-commercial projects. We encourage companies, local innovators, and all others to take advantage of special prototyping deals such as the Advanced Circuits BareBones or $33 Each specials.
The router takes Gerber 274X files and Excellon drill files, the standard file formats used in industry. All of your files should be in Gerber 274X format, except for your Drill File which should be in Excellon format.
Please use the following file names for your layers. Your software may assign file extensions, but these are of no use to us. Please name your files correctly, and without extensions (e.g., "TopLayer", NOT "TopLayer.cmp").
• Top Copper Layer: "TopLayer"
• Bottom Copper Layer: "BottomLayer"
• Drill Layer: "DrillUnplated"
• Outline Layer: "BoardOutline"
For a two-sided board, you’ll need 4 files.
For a single-sided board, you will have only one Copper layer. It is necessary to specify which copper layer in the file name, or your board may be mirrored. Single-sided bottom boards are common for designs that use all or mostly through-hole components, whereas single-sided top boards are common for designs that use mostly surface-mount components.
Neither the top nor bottom layers should appear mirrored when you preview; the stack of layers should appear as though being viewed from the top side of the board, even when viewing the bottom layer. The board router's software handles the mirroring necessary for milling the bottom layer.
All files must be compressed into a .ZIP archive; other archive formats are not acceptable.
