Overview
ISO 16525-1:2014 specifies general test methods for isotropic electrically conductive adhesives used in wiring, die attach of semiconductors, and surface assembly of printed circuit boards. It defines sampling, atmospheric conditioning and a core set of tests to characterize adhesive properties both before and after curing. This part does not set performance limits or specify bonded assembly performance - it standardizes how to measure key material attributes for quality control, R&D and supplier verification.
Key topics and requirements
Applications
ISO 16525-1 is essential for:
- Adhesive manufacturers performing product characterization and QC.
- Electronics OEMs and contract manufacturers validating adhesives for wiring, die attach and PCB surface assembly.
- Independent test laboratories and materials engineers assessing thermal, mechanical and moisture-related behavior.
- R&D teams comparing formulations (viscosity, Tg, moisture uptake, thermal expansion).
Related standards
- Other parts of the ISO 16525 series (electric characteristics, heat transfer, shear strength, fatigue, environmental tests, electrochemical migration, high-speed signals).
- Normative references used in ISO 16525-1: ISO 62, ISO 291, ISO 1183‑1, ISO 2555, ISO 3219, ISO 11357‑2, ISO 11359‑2, ISO 15184, ISO 2528, ISO 4664‑1, ISO 10364.
