PurePulse Foundation "All Waveform" Electrostatic Discharge System

PurePulse HBM Test System including the Signatone ChechMate series semi-automatic probe station and FP100 flying probes.

PurePulse Foundation "All Waveform" ESD System

A unified modular system that provides ALL 2-pin ESD testing for packaged parts, bare die, and wafer level devices. Expandable to provide comprehensive testing for Compliance to ESD Standards and Engineering Evaluation of design issues and new technologies.

The two-pin architecture not only eliminates limitations associated with relay-based test systems, but also provides unprecedented testing flexibility. The PurePulse HBM module delivers exceptional pulse accuracy, while the unique measurement capabilities allow access to comprehensive and valuable device data.


Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.

ESD can create spectacular electric sparks (lightning, with the accompanying sound of thunder, is a large-scale ESD event), but also less dramatic forms which may be neither seen nor heard, yet still be large enough to cause damage to sensitive electronic devices. Electric sparks require a field strength above approximately 40 kV/cm in air, as notably occurs in lightning strikes. Other forms of ESD include corona discharge from sharp electrodes and brush discharge from blunt electrodes.

ESD can cause a range of harmful effects of importance in industry, including gas, fuel vapour and coal dust explosions, as well as failure of solid state electronics components such as integrated circuits. These can suffer permanent damage when subjected to high voltages. Electronics manufacturers therefore establish electrostatic protective areas free of static, using measures to prevent charging, such as avoiding highly charging materials and measures to remove static such as grounding human workers, providing antistatic devices, and controlling humidity. ESD simulators may be used to test electronic devices, for example with a human body model or a charged device model.

Signatone and Grund Technical Solutions (GTS) have combined efforts to offer various ESD test solutions including  HBM, TLP, VF-TLP, MM, HMM and more.
