Continuing on the tangent, the attachment from the ESD Association lists real life events that are dependent on the local environment. Complying with the regulations keeps our officers out of jail; designing for robustness keeps our customers happy. We have an internal requirement within Sensormatic to design for levels above those specified in the standards. Our field experience (correlating somewhat to the information in the attachment) supports the requirement for design robustness.
<<Doc1.doc>> This is the Web Site: http://www.esda.org/ Our products comply with the product family standards which set the ESD levels for compliance; we test beyond that for internal compliance. So unless the changes in the standard change the rise time or other pulse parameters, your products are really bound by product family standards, perhaps coupled with your internal requirements.
