Bob has apparently had different experiences than I. I see about half that as the norm. Usually only one respin is needed to get the circuit and board just right. The extra respins are due to inevitable requirement changes as the product plans evolve. This has much more to do with how much the company knows what they are doing and how well they manage the new product process than correcting design errors. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
