Engineers Working Together To Get It Right First Time

摘要

Each one of the design rules that production departments produce is aimed at reducing that risk to improve production yield. They make a difference to the production cost by reducing the number of faulty boards leading to scrap, rework or failures in the field. Although each and any of the rules can be bent or broken, there is always a price to be paid in terms of manufacturing cost and/or production yield. Many designs end up with areas where the required size, performance, cost, or power consumption can only be achieved by operating at the limits of the manufacturability guidelines. In partnership with the manufacturing team, it is often possible to identify ways of easing the constraints elsewhere to minimise the impact on yield and maximise reliability.
