Hello All, Is there a book or a software tool out there that I can buy and use to help develope a method for estimating how long it would take to drill (or rout) a PWB. The information I would typically have at hand is the CAD design file and Gerber information (the drill table and Gerber drill file). I would probably have to obtain drill machine information from drill machine manufacturers or PWB suppliers. I'm not looking for absolute accuracy here, just a means of computing a rough drill time and estimating comparisons between various drill diameter and hole quantity options......sort of an up-front DFM tool.
