Abstract:
Electrostatic Discharge ( ESD) immunity test is a test of required electromagnetic interference ( EMS) project of many electronic products． The weighing controller failed to pass the test，and it is too complicated to modify the circuit with large-scale． This paper presents a new idea of electrostatic discharge improvement． By analyzing its structure， it is deduced that electrostatic discharge due to the poor structure，improves the structure of EUT by using flat type copper wire，then improves the liquid crystal display part and the inner shell structure respectively． The test result shows that the equipment succeeded in passing the test，which proved that the method is effective，and it offers some reference value when some circuits are too complex to modify．
