Abstract

Electronic devices are getting more and more sensitive to the electro-static discharge (ESD) because of their smaller size and higher frequency. An electronic dictionary device studied here has failed in the ESD immunity test according to the IEC61000-4-2 standard. Many factors which could impact on the ESD immunity performance of the device are investigated in the test and some suggestions are also given in this paper for improving its performance. The improving suggestions are listed and analyzed combining the device in detail in this paper: 1) improving the ESD immunity performance of the dictionary´s PCB; 2) changing the outer package material for the dictionary, protecting the LED; and 3) building a complete ESD test system. The device has gained a significant improvement on the ESD immunity by using merely part of our suggestions. We hope that this could be a reference to the manufactures of similar devices as well
