Guys -- I have a PCB specification/manufacturing question, and I figure some of the gurus on this list might have the answer. I want to create a PCB with some material (0.030", say) milled off the top of the board at specific locations. That is, I want to cut grooves into -- but not through -- the board.
What is the best way to acheive this (besides buying a milling machine and doing it myself, that is)? Specific questions: * How do I capture this information so a PCB fab house can use it? Gerbers only give 2D info, they don't specify anything about where to mill or route a channel into the PCB. Or should I define a separate "mill" layer, and call out the milling depth in the fab drawing? * Is it possible to capture this milling info using PCB? I guess I can just draw tracks on the "mill" layer . . . . . right? * Which PCB houses do this kind of work? I'd prefer to hear from folks who have actually had this type of job done, rather than just guesses or hearsay. OTOH, all suggestions are welcome. Cheers and thanks for any info, Stuart _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
