Any environment that minimizes risks. When engineering puts the process=20 through a standard set of rules that serve to enforce predetermined=20 policies and the 10,000 finished boards are delivered and won't function=20 without manual rework involving discrete wiring, assigning=20 responsibility is not difficult. In the prototype stage a few discrete components may not be a big deal.=20 It used to be that the most frequent goof was getting a cable connection=20 in opposite order. What is the best route anyway? Do you minimize board size? Separate=20 signal lines? On 5/15/2013 11:29 PM, veegee wrote: > Serious question.
