ESD Simulator

ESD Simulator, Abbreviation is  HESD, which could simulates the phenomenon of electrostatic discharge interference. And it is used to evaluate the immunity of electrical equipments to this phenomenon. HESD designed per ergonomic, excellent performance is our focus on the core of it. Including the small generator and the compact controller. Now, we would like to use touch panel to guarantee the reduction of time and effort, it's very easy to operate with manual and automated test mode, in addition, it's suitable for long time testing,HESD is best choice for your immunity testing. There are some standards for your requirements as follows: IEC/EN61000-4-2 IEC/EN 17626.2 ISO 10605 ISO 14304 IEC/EN 61000-6-1&-6-2-T IEC 61340-3-1 IEC 60571 IITU-T K20 ANSI C63.16 MIL-STD-1512/-1514/-750D/-883 RTCA/DO-160 How and why we would to use it? 16KV/30KV discharge voltage External IEC testing level, L1-L4 Discharge fr...

PCB EMC design

PCB EMC design 1）Analysis of signal spectrum A1 = 2τ / T A2 = 0.64 / T f A3 = 0.2 / T tr f2 The shorter the rise (or fall) time, the richer the high frequency components of the signal. （2）Analysis of interference sources ΔI Noise interference Common mode interference and differential mode interference (a)Differential mode radiation （b）common mode radiation Crosstalk When a high frequency current flows through a signal line, the interference voltage will be induced on the signal line adjacent to the PCB board. （3）Wiring design technology ◊  When wiring, make all signal loop areas (especially high-frequency signals and sensitive signal loop areas) as small as possible. ◊  High-speed signal lines should not be crossed over the partition area or over the unrelated reference plane. ◊  In analog circuit and RF circuit designs, as well as in dual panels without a power ground plane, the guard wires are often used to prot...
