Human Body Discharge (HBD) ESD ESD failure limits have been measured in a variety ofThe Human Body Discharge model (HBD) was developed silicon integrated passive devices using the Human Body as a standard to mimic the electrostatic discharge that may Discharge Model. The failure mechanism for these circuits is result from the handling of electronic devices.[ii] A typically the destructive breakdown of the thin insulator layer commonly-used circuit for industrial testing [iii] is shown in in metal-insulator-metal capacitors. The capacitors in this Fig. 2. In this circuit, the charge capacity of the human body is particular technology have a static breakdown of 70 to 1OOV. modeled by the 1OOpF capacitor and the discharge resistance Failure from ESD events for a single capacitor typically by the 1.5KQ resistor. Obviously, the actual conditions vary occurs for voltages of 200 to 300V. Tests of more complex widely, but this model is accepted for characterization circuits show that the ESD performance is extended by using purposes. In the test, the switch is first thrown to the left so series arrangements of capacitors. In some circuit types it is that the capacitor is charged to the desired test voltage, VESDpossible to use inductive shunt protection. This has been Then the switch is thrown to the right, so that the capacitor found to increase the failure voltage to above 3KV, which was the limit of the test equipment.

La crise sanitaire a vu la résurgence de la question du logement dans l’action publique. Si celle-ci souffre de contradictions, sa prise en charge croissante par les intercommunalités ainsi que sa rencontre avec les enjeux écologiques sont des voies à approfondir.
L’illégitimité assignée aux manières de «faire de l’argent» des Tsiganes et Voyageurs, trouve en partie son origine dans la méconnaissance des activités valorisées. Dépassant la seule vision économiciste, l’étude de ces pratiques rend compte du caractère indissociable de la sphère économique et des sociabilités familiales et communautaires. Souplesse et liberté d’organisation, absence de notion de carrière, apprentissage familial informel, prodigalité sont autant de réalités qui s’opposent à la réglementation et à la rationalisation croissantes. Dans ce contexte socio-économique qui affecte leurs pratiques productives, les familles se positionnent de façon diversifiée, notamment vis-àvis de l’école et des dispositifs d’insertion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
