Pete, I find your blogspot to be very informative and enjoy the commentary that is included. It makes the projects very personal and provides a rationality for your endeavors. Recently, I have been intrigued by the cnc routing technique for creating circuit boards and have visited the web addresses that were noted on your blog. I was curious how long you have been utilizing the technique and what is the largest board (dimensionally) that you have created? Would you provide any commentary and caveats on utilizing the cnc routing technique? Thank you so much for sharing your knowledge!
ReplyDeleteHi OM,
ReplyDeleteI have been using a CNC for about 10 years now and most of my work involves the arranging of islands mush like you would do with ugly construction. Most bargain CNC's (like in the $300 to $400 range) can work with Gerber files so that you can mill PC boards that look like they have been etched. Frankly I just don't and didn't want to invest the time learning some of the PCB programs (like Eagle) to design real boards. The PCB limitation is driven entirely by the size of the CNC bed work area. the largest size board I could reasonably do is about 6" by 10". That is a fairly large board and most of the stuff I do is in the 2X3 to 4X6 range. The real beauty of the CNC is twofold --rapid prototyping and when you want a second board --just push the START button. Hope than answers your questions.
Bottom line I use it in a way that fits me but perhaps only using 10% of the capability. If you are into VHF/UHF/Satellite stuff you can mill precise strip line circuits.

Pete,
ReplyDeleteThanks for the response.
