Why spend $1500+ on commercial ESD targets when you can build your own for under $100? This EMC lab's clever DIY solution uses high-voltage resistors and SMD components to create an IEC 61000-4-2 compliant target that rivals expensive commercial alternatives.

Real-world ESD discharge currents during semiconductor assembly differ dramatically from standard test predictions. A new Discharge Current Sensor reveals that actual currents are lower but faster than expected, challenging current protection designs for Multi-Chip Modules and Systems in Package.

Overconfidence in basic ESD testing can create dangerous blind spots. Three case studies reveal how standard floor resistance tests miss critical system failures when mobile equipment loses electrical contact, exposing sensitive electronics to static damage despite apparent compliance.

Award-winning research reveals that advanced chip assembly faces unique ESD risks as dies stack closer together. 3D electromagnetic modeling shows discharge currents can exceed 2 amperes in picoseconds, potentially damaging sensitive die-to-die connections despite controlled cleanroom environments.

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.

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.

Traditional Charged Device Model testing falls short for bare dies in 2.5D/3D devices. With discharge currents reaching 500 mA at just 5V, existing methods can't handle the unique challenges of testing unpackaged components. CCTLP emerges as a promising alternative for reliable low-voltage testing.

A new version of Technical Report TR18.0-01-25 (TR18) on ESD Electronic Design Automation (EDA) Checks by the ESD Association’s Working Group 18 is about to be released. This article, divided into Part 1 and Part 2, provides guidelines for the EDA industry and the ESD design community for establishing a comprehensive ESD verification flow to address the ESD design challenges of modern ICs.

This article introduces an upcoming Technical Report (TR18) from the ESD Association on Electronic Design Automation checks. It details integrated ESD verification throughout IC design phases, covering schematic-based topological checks and layout-based verification to ensure comprehensive ESD protection in modern circuits.
