Predict Non-Contact ESD Before You Build

Electrostatic discharge (ESD) testing is a critical step for manufacturers ranging from consumer electronics to aerospace. Standards require rigorous testing before products reach the market. Oftentimes contact ESD testing is preferred for its control and quantifiability.
But what happens when contact testing isn’t feasible?
EMA has developed a cutting-edge ESD generator within Ansys Charge Plus to simulate and analyze non-contact ESD events. Our approach combines non-linear air chemistry with electrodynamics, allowing engineers to anticipate ESD behavior before physical testing. This is essential in the design of electronics with LCDs, charging ports, or non-metallic enclosures.
Non-Contact ESD Simulation

Whether you’re in early product development or troubleshooting a failed ESD test, EMA can help you:
- Identify vulnerabilities such as secondary ESDs, displacement currents, and field coupling through seams and apertures
- Predict voltage and current waveforms at connector pins and PCB nets
- Avoid over- or under-designing by relying on simulation rather than guesswork
- Save time, reduce costs, and improve product reliability
