By many, ESD is seen as just one type of electrical stress. EOS on the other hand, describes a wide number of outcomes resulting from multiple stresses or root causes. There will be an ESD event if two objects are at different charge levels and a rapid, spontaneous transfer of an ElectroStatic charge between them occurs.
More on that in a little while. The following table lists the main differences:. Many failures in the electronics industry can be contributed to EOS.
Yes, ESD has received a lot of attention over the past years. In such cases, the engineer analyzing the failures has no choice but to complement the results of the failure analysis techniques with a thorough investigation of the circumstances surrounding the affected units, from their design and qualification to their actual use in the field. This would include analyzing qualification and reliability data, lot histories, equipment set-ups, and even operator assignments, so that any discernible pattern exhibited by the affected lots can be given greater focus.
Unfortunately, such an endeavor is complicated by the fact that attributes can change over time and as the units undergo processing. For instance, a gross EOS failure attribute may have originated from a subtle ESD damage that was just aggravated into a full-blown EOS damage during electrical testing. Simulation is a good method for confirming a cause, but it is only effective if the appropriate simulation conditions can be defined and executed with reasonable control, and if the failure attributes are exactly replicated by the simulation performed.
For dates and locations in South East Asia, please contact us at se-asia. If a course is canceled, refunds are limited to course registration fees. Participants learn to develop the skills to determine what constitutes a good ESD design, how to recognize devices that can reduce ESD susceptibility, and how to design new ESD structures for a variety of technologies.
From the very first moments of the seminar until the last sentence of the training, the driving instructional factor is application. We use instructors who are internationally recognized experts in their fields that have years of experience both current and relevant in this field. The course notes offer dozens of pages of additional reference material the participants can use back at their daily activities. Christopher Henderson received his B.
