| + | An electrostatic discharge (ESD) is the sudden flow of current between two electrically charged objects, caused by the break-down of the dielectrics separating them, i.e., dielectric breakdown. In the case of electronic devices, the resulting current flow and possible spark can permanently damage the device (see Figure 1). An often recited yet unsubstantiated quote is “…losses associated with ESD in the electronics industry are estimated at between half a billion and $5 billion annually.” In reality, estimating the exact cost of ESD loss is extremely difficult; nonetheless, ESD forces the development and testing of many hardware prototypes during design and manufacturing and contributes to a high number of warranty claims with loss of consumer confidence if a failure occurs in the hands of the consumer. Therefore, electronics manufacturers go to great lengths to properly shield sensitive components and design systems to reduce, dissipate and neutralize static charge. | ||
