How should the electronic industry detect the static voltage?

Nowadays, many types of microelectronics industry need to effectively control the production defect rate and quality reliability problems, including integrated circuit manufacturing (wafer manufacturing and chip sealing test), flat panel display manufacturing (front tftfab, middle LCD box assembly /oled assembled display module, MEMS (front wafer manufacturing and rear device packaging), etc.

Taking the problems of microelectronic equipment caused by human static electricity in factories as an example (humanbodymodel, human electrostatic discharge model), let's examine the technical cognition and practical methods related to human static electricity in human electrostatic analysis.

Based on the LED electrostatic failure mechanism (positive conduction electrostatic discharge), the larger the discharge current range generated by human discharge, the higher the risk of SMDLED electrical failure (usually the amplitude of SMDLED working current is a few milliamps) (LED electrostatic damage in LCD screen module factories is often referred to as bad light - that is, turn on low current and no longer emit light);

Therefore, in order to effectively protect SMDLED from the "breakdown" of electrostatic discharge on the body of workers, it is necessary to control the human body electrostatic voltage of operators at work sufficiently low (the LED carries current * to determine the human skin resistance).
