Well-insulated portable devices are exposed to field coupled impulsive ESDs if they carried e.g., in a backpack. These pulses created by tribo-charging of metallic objects as result movement and subsequent discharges. Due the size low charge voltages, frequency spectrum exceeds 5 GHz. The can damage or upset devices. paper quantifies voltages transient strength reproducing typical scenario capturing fields with bandwidth more than 10 estimated comparing measurements numerical modeling
This paper presents a novel peak detect and hold (PDH) circuit for the measurement of voltage electromagnetic-field probes. These probes are used to capture fields generated by electrostatic discharge (ESD) events in non-grounded portable devices. Therefore, combining small size, low power consumption nano-second operation is needed. A topology using discrete bipolar transistor structure with OTA common-base storage capacitor charge control optimally meets requirements. The performance...
ESD susceptibility scanning is an effective method to find the causes of soft failures in electronic systems. A local probe used scan system for sensitive areas. However, voltages induced by are often unknown. This paper quantifies from different probes when injected into traces and flex cables, compares values caused IEC 61000-4-2 gun contact mode. The goal guide reader select voltage levels during scans a way that avoids may be associated with injection cause failure.
As a first step in survey of the ESD risk to mobile devices, small, battery powered portable system that emulates device for purpose capturing its electrostatic discharge environment is described. The contains multiple electric, magnetic field sensors as well current sensor capture events and their associated transient fields. Bandwidths > 2 GHz are achieved. connected via an analog optical fiber. It intended provide reference data fields captured controlled conditions order determine type...
ESD discharges to antennas can damage the RF front end. In particular, with highly inductive ground connections allow large ESD-induced voltages at their terminals. This work investigates properties of an switch used as antenna tuner by measuring and currents its terminals building a SPICE model. The goal is predict threshold when in
This paper describes two modifications to an ESD generator: One that approximates human skin ESD, and another one discharges body worn equipment. generators follow the IEC 61000-4-2 or related standards. Variations mainly refer changes in RC network remove rise time filtering structures for obtaining times contact mode faster than 0.85 ns. from equipment shows up 3 larger peak values 3.75 A/kV specified standard. To test equipment, it is reasonable increase current a given voltage. The first...
Downscaled semiconductors are at risk of CDM like ESD events during manufacturing, packaging, testing and placement. The reduction in silicon area spent for protection circuits modern ICs makes the devices more vulnerable by reducing damaging thresholds. Following this trend industry it is getting crucial to monitor processes where these handled. A new type sensor using multiple antennas along a coax-cable used locate events. Due large quantity antennas, has potential be complex environments...
Detecting personal ESD by using electric field sensors attached to the clothing was evaluated across different realistic charge and discharge scenarios. The event itself is detected associated fast collapse of at human. Its magnitude determined E-field change calibration that relates on body voltage body. Two are used enhance accuracy. One these positions hereby front-side leg other back-side. paper explains measurement principle gives example results.
