Except for reducing BOM costs, there may be no allowance or budget for any change whatsoever. <P>But when an ESD problem arises, the Sustaining Engineer may have a limited subset of options for recovery as compared to <a href="http://pragma-design.com/pd/index.php/services/production/12-line-returns/14-production-probs">Production Problems.</a><P>But for BOM cost reductions, the risk to compliance must be considered. <P> If <a href="http://pragma-design.com/pd/index.php/tools/9-services/12-esd-scanning">Susceptibility Scanning</a> shows no quantifiable reduction in robustness or increase in susceptibility by removing a TVS device, then the confidence factor in the cost reduction goes up and can be justified earlier in the product cycle.
