IEC 61189-2-630:2018

IEC 61189-2-630:2018 defines a test method for materials used in interconnection structures, focusing on moisture absorption after pressure vessel conditioning. For engineering teams and laboratories, it provides a structured technical reference for evaluating how candidate materials respond to controlled conditioning and subsequent moisture uptake. That matters in documented evaluation, product qualification, and compliance workflows where material behavior can affect reliability, process selection, and technical review of printed board and related assembly materials.

Purpose of IEC 61189-2-630:2018

The purpose of IEC 61189-2-630:2018 is to support consistent assessment of moisture absorption performance in materials intended for interconnection structures. By defining a specific test approach after pressure vessel conditioning, the document helps users compare results more reliably across laboratories and quality workflows. It is especially relevant where material selection, risk management, and technical validation depend on understanding how a substrate or related material behaves under moisture exposure conditions that may influence performance and long-term stability.

Compliance applications of IEC 61189-2-630:2018

IEC 61189-2-630:2018 is commonly used in laboratory evaluation, supplier qualification, and conformity assessment preparation for printed board materials and other interconnection structure materials. It may be referenced during procurement review, incoming inspection planning, or technical documentation for product evaluation where moisture-related behavior is part of the acceptance logic. The method is useful in testing workflows that require repeatable evidence for technical compliance, especially when organizations need a defensible basis for comparing material candidates or validating process-sensitive designs.

Benefits of IEC 61189-2-630:2018

Using IEC 61189-2-630:2018 can improve testing consistency and support more dependable engineering documentation. A defined method helps reduce ambiguity in laboratory practice, which is valuable for quality assurance, technical assessment, and conformity assessment preparation. It also supports procurement decisions by giving stakeholders a clearer basis for comparing materials under the same conditioning approach. In operational terms, that can help reduce risk, improve traceability, and strengthen the evidence used in compliance workflows and product validation activities.
