<p>Issues to consider during the Design Phase that may affect ESD Robustness and Susceptibility:<br mce_bogus="1"></p> <ul><li>New Component Revisions and Pinouts<ul> Do these increase overall system susceptibility from previous versions?</ul></li> <li>New PCB process constraints<ul>Will fewer layers force more critical signals to exposed layers?</ul></li> <li>New enclosure constraints<ul>Will shielding cost-reductions or new gasket materials cause problems?</ul></li> </ul><P>A great deal of advanced CAD/FEA simulation technology advances can provide answers here, but sometimes hard data on the real thing can provide a better answer, or perhaps provide a validation of simulation results.<P> A library of <a href="http://pragma-design.com/pd/index.php/tools/9-services/12-esd-scanning">ESD Susceptibility maps</a> for previous known-good systems can be an invaluable review tool to understand what works, what doesn't, and what problems are nearing the edge of reliability. <P>Incidentally, benchmarking the susceptibility maps of competing systems can help justify cost-reductions or robustness improvements.
