FICDM testing wasn't designed for today's tiny chiplets and flip chip assemblies. Part 1 explores critical challenges: probes too large for microbumps, unreliable air discharge below 250V, and the mounting dilemma for bare die products.

Secondary discharges during Field-Induced CDM testing aren't just measurement anomalies—they're real stress events caused by mechanical bouncing of the pogo pin. This groundbreaking investigation reveals how contact vibrations trigger unintended zaps with opposite polarity, provides electrical proof of the mechanism, and offers practical solutions to prevent this hidden reliability threat.

High-speed automotive serial links supporting ADAS features face a critical challenge: meeting stringent system-level ESD requirements while maintaining signal integrity at 10+ Gbps. This column presents an innovative on-chip protection architecture embedding ESD clamps within T-coil circuits, achieving 8kV ISO protection while supporting data rates exceeding 36 Gbps.Retry

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.

USB-C's high-speed data lines need robust ESD protection, but TVS device placement matters critically. New research reveals why positioning protection behind AC coupling capacitors—not in front—delivers superior IC protection for sensitive SuperSpeed applications.

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.

The teaser maintains a technical, authoritative tone that should appeal to engineering professionals while highlighting the article's key experimental findings. It addresses the misconceptions about AC ionizer safety and emphasizes the quantitative approach taken in the study, which should generate interest among readers concerned with ESD protection in semiconductor manufacturing environments.

By understanding resistance in discharge circuits, engineers can implement effective protection through grounding, dissipative materials, and equipotential bonding—creating comprehensive ESD control programs that safeguard sensitive electronic components.
