Fabrication guidance Day and time: This semester, cutting your PCB is arranged by an appointment only. You are invited to assist in the fabrication process. Best dates: Tu, Th, and Fri. Please send me an email first. Cost: Free for reasonable jobs. But, repeated jobs (for example due to errors) will cost you or you will need to send them outside. Files needed to cut PCBs: PLEASE, READ THIS SECTION VERY CAREFULLY. You need to bring/emaila single directory with four files(plus optional when applicable): 1) Top copper file (Gerber) 2) Bottom copper file (Gerber) 3) Drill file (Excellon), 4) Board contour file (Gerber) Optional – Mechanical holes/cut-outs file (as non-plated holes: Excellon) Optional – Rubout file for each layer, when applicable(Gerber) Double check: To be absolutely sure your files are in good condition and contain proper data, please use Gerber viewer software of a different company to check your design graphics. For example, I use very simple gerbv open-source application: NOTES: If you do not have a board contour file, your board will not be cut (!) If you email/bring additional files that are not needed, your board will not be cut (!) If you include (more than allowed) text/graphics or additional symbols (dimensions, etc.), your board will not be cut (!) Additional information: For current limits calculation use on-line resources such as: Board cutout – all cutout data must be included in the board contour file. You can cut complex shapes (including internal cutouts). Consider that the tool used to do this job is a 2mm (or 1mm depending on board size and thickness) mill end. Therefore, internal corners will be rounded accordingly.
