Case Study: Point of Sale Terminal ESD

Field failures traced to ESD-induced USB hub damage in deployed POS terminals. Through systematic H-field probe analysis, we identified poor connector-to-chassis bonding as the root cause—a preventable design oversight with expensive retrofit implications.
EMC Bench Notes

Understanding and Dealing with ESD

ESD failures are increasing as products shrink and use lower voltages with smaller noise margins. Learn how to trace ESD current paths using H-field probes and oscilloscopes to quickly identify where discharge energy flows, enabling targeted fixes like bonding and shielding to solve immunity problems efficiently.
