Abstract
Recent regulations
have demanded that electronics manufacturing companies control emissions from
their products and the susceptibility of their products for Emissions from
other products. In addition, unexpected product failure and the ever-present
demands of technology are also forcing the electronics industry to face the
need to maintain Electrical Integrity. The investigations into high-speed
design techniques have shown three major causes of failure: emissions from
interconnecting conductors; poor PCB layout and lack of technical knowledge in
Electro Magnetic Compatibility (EMC). Catching these kinds of electrical
integrity problems early in the design phase allows designers to take timely
action without jeopardising project time scales. The work reported here
presents design for manufacturing guidelines and rules to maintain electrical
integrity in Printed Circuit Boards (PCBs). Currently, a common method for
handling EMC is through compliance testing of the final product. Similarly,
noise budget is measured on finishing prototypes. Since product life cycles are
reduced, dealing with EMC late in the design cycle is undesirable. The cost of
fixing may also be higher at a final stage because only a few options are
available to correct the problem. A 'find and fix' approach is no longer
acceptable. More and more companies are facing or will soon be facing EMC and
electrical integrity issues. The majority of analysis tools available today are
targeted towards simulation engineers. Such tools are not easy to use and are
dependent on the availability and accuracy of complex simulation models.
Moreover, they also tend to be ineffective on how to correct potential EMC
problems.
