PCB designers working with advanced and complex designs are constantly pushing the boundaries to satisfy the signal integrity of routed differential pairs and busses. Those who work with flexible and flex-rigid PCB designs are perhaps the most demanding of all. A while ago, the introduction of the curved corner style for routing trunks in CADSTAR made a big difference to this group of users.
Improving communication between multidisciplinary teams is a key way companies can maintain a competitive edge and promote design quality. Where PCB designs are outsourced, this becomes even more important.
