IEEE 370-2020

IEEE 370-2020 is a technical standard for the electrical characterization of printed circuit board and related interconnects at frequencies up to 50 GHz. It is relevant to high-frequency signal integrity work where PCB traces, vias, connectors, and other interconnect structures must be measured and compared with confidence. By defining a consistent approach to characterization, it helps engineers and test teams support more reliable design decisions, performance evaluation, and compliance-oriented documentation for demanding electronic systems.

What is IEEE 370-2020?

IEEE 370-2020 addresses methods for electrically characterizing printed circuit board interconnects and closely related structures over a wide frequency range. Its purpose is to support repeatable measurement and analysis of interconnect behavior, especially where parasitics and frequency-dependent effects can influence system performance. In practice, the standard is used as a technical reference for how these structures may be assessed, helping reduce ambiguity when evaluating high-speed PCB designs and related assembly interconnects. IEEE 370-2020 is therefore useful where consistent test interpretation matters.

Where is IEEE 370-2020 used?

This standard is commonly used in PCB design, signal integrity validation, and laboratory test workflows involving high-frequency interconnects. It is relevant to boards, packages, connectors, and transition structures used in advanced electronic equipment where performance must be understood up to 50 GHz. Teams working on components, circuits, devices, and system-level interconnects may rely on IEEE 370-2020 when comparing measured results, tuning models, or documenting electrical behavior for engineering review and procurement support.

Why is IEEE 370-2020 important?

IEEE 370-2020 matters because electrical characterization at very high frequencies can vary significantly without a common method. A defined standard helps improve consistency across testing, design validation, and supplier communication, which can lower the risk of mismatched assumptions about interconnect performance. For organizations managing high-speed electronics, it supports better control of measurement practices, more dependable comparison of results, and clearer technical evidence when evaluating whether a PCB interconnect meets expected requirements.
