Short for ElectroStatic Discharge, ESD is one of the few things that can damage or destroy a computer or parts in a computer. Like the shock you receive when rubbing your feet on the carpet and touching something metal, ESD can occur when working in your computer and can cause damage to ...
There are three (3) predominantESD modelsfor IC's: 1) theHuman Body Model (HBM); 2) theCharged Device Model (CDM); and 3) theMachine Model (MM).The HBM simulates the ESD event when a person charged either to a positive or negative potential touches an IC that is at another potenti...
TD 4.1.2is related to USB Type-C test for Rp that must not be present for source application when source is OFF. ESD protection will be transparent in this test. TD 4.12.2is related to USB Type-C test checking if there is only one upstream port in a hub port device. ...
Electrostatic discharge occurs naturally and can damage electronics beyond repair. Learn what ESD is & how to protect your equipment.
We can broadly classify the duration of pulse widths into long (>100 μs) and short (<100 μs) types, and magnitude into exceeding an individual component's EOS threshold. For short pulse widths the most common failure mode is junction spiking. Intel® Manufacturing Enabling Guide May 2016...
as well as easy removal of any tissue that coagulates on the knife tip. In addition, even when the knife is retracted completely, the small disc on the tip remains projected so that it can easily be used for coagulation and haemostasis by contact. In my opinion it is a safer, easier-...

A high-voltage NMOS transistor for ESD protection is coupled between a high-voltage I/O pad and a low-voltage terminal, and has a parasitic component between its source and drain. A trigger has an input coupled to the high-voltage I/O pad and an output coupled to the parasitic component...
The Charged Device Model (CDM) evaluates susceptibility when a device itself becomes charged and then discharges to ground. For CDM testing, the device is charged with a high voltage supply before being discharged through a current limiting resistor. JEDEC JESD22-C101 defines standard CDM testing....
1 InternalUse 潜在性:有些元器件在损伤后并不马上表现出来，只是性能下降，并不马上失效；随机性:只要电压超过或接近静电敏感电压阀值，就可能发生静电损伤，在生产的各个环节，包括成品运输等都可能产生ESD损伤；隐蔽性：人体带电是电子产品静电损伤主因，几KV的人体静电，对人而言放电感受几乎没有，对元器件却是...
