emi control

ARC Technologies LLC, a Hexcel Company, has developed a reputation for providing an unrivaled range of advanced materials that help military platforms operate and survive in a high-end threat environment.

A 1988 study of current distribution in printed circuit boards reveals how return‑current paths, ground‑plane impedance, and trace coupling drive EMI and signal‑integrity issues. Its insights on low‑impedance ground structures remain foundational for today’s high‑speed digital designs.
