Guidelines and requirements are given for test cell geometries, generator specifications, test levels, discharge rate and waveform, types and points of discharge on the “victim” product, and functional criteria dischaarge gauging product survivability. Some components are electrostatic sensitive – meaning they are so delicate, even the static electricity in a body can destroy them.
Like all electronic devices, this cardiograph is susceptible to electrostatic discharge esd. Tlchargez Symbollmark Reader DC, le seul logiciel gratuit qui permet d’ouvrir quasiment tous les PDF, d’y faire des recherches, de les imprimer et d’interagir avec eux. Electrostatic discharge esd is defined as the rapid, spontaneous transfer of electrostatic charge induced by a high electrostatic field.
When a staticallycharged person or object touches an electrostatic discharge sensitive esds device, there is a possibility that the electrostatic charge could be.
As there is often no real path through which the charge can flow the resultant voltage may remain in place for some time and this gives rise to the term “static electricity”. These invisible forms of ESD can cause outright device failures, or less obvious forms of degradation that may affect the long term reliability and performance of electronic devices. Another way in which damage can occur as a result of ESD is when the high level of voltage causes breakdown to occur in a component in the device itself.
