Is 2 ohms good continuity?

The IPC/WHMA-A-620 Rev A standard outlines specific guidelines for electrical continuity testing in class 3 assemblies, which are typically used in critical applications requiring high reliability. This standard acknowledges the importance of establishing clear test requirements between manufacturers and users to ensure product quality and safety.

In the absence of mutually agreed-upon test requirements, the standard recommends a continuity specification of 2 ohms or 1 ohm plus the actual resistance for class 3 assemblies. This threshold serves as a reasonable benchmark for determining whether a connection is electrically sound and free from defects.

Cirris, a reputable company in the field of electrical testing equipment, endorses this approach. By adopting the IPC/WHMA-A-620 Rev A standard, Cirris offers customers a reliable method for determining continuity test specifications that align with industry best practices.
