It is published by (Association Connecting Electronics Industries), the global authority for electronic assembly and packaging standards. The document focuses specifically on the cleanliness of printed circuit boards (PCBs) — a factor critical to long-term reliability, especially in high-humidity or high-voltage environments.

The importance of this standard stems directly from the evolution of the electronics industry. The rise of high‑density packaging, chip‑scale packages, and bottom‑terminated components (like QFNs and LGAs) has created tiny, difficult‑to‑clean spaces under components. A traditional "no‑clean" process, once considered sufficient, can leave behind residues that lead to electrical leakage and eventual failure, especially in high‑reliability applications.
The is indispensable for maintaining the reliability of printed board assemblies. By consolidating years of industry experience into a single, comprehensive guide, it allows manufacturing teams to make informed decisions regarding cleaning agents, processes, and validation techniques.
