SparkFun has published an outstanding guide to the numerous different problems you could run into when you lastly decide to get a circuit card professionally produced. We assume that many of you aren’t running a expert design firm and will appreciate these suggestions gleaned from years of experience. They offered a guideline list, Eagle DRC, and CAM data to assist you get it best the very first time. The end goal is developing a board that won’t be prone to producing errors. The tutorial starts by covering trace width and spacing. They suggest avoiding anything less than 10mil traces with 10mil spacing. For planes, they boost the isolation to 12mil to avoid the planes pouring onto a trace. They also talk about annular rings, tenting, labeling, and generating the proper gerber and drill files. SparkFun isn’t completely infallible though, and handles to create a coaster from time to time.
SparkFun naturally complied with up this strict tutorial with a guide to unorthodox header hole placement. If you want to discover much more about Eagle, have a look at [Ian]’s summary of Eagle 5 and destroy & Wesen’s design videos.
