Unintended paths for electrical current that can degrade signal integrity.
To consolidate industry knowledge on cleaning technologies, chemistry, and equipment into a single resource. It is a guideline , not a mandatory specification, meaning it offers advice rather than strict "pass/fail" requirements. Current Version: IPC-CH-65B , released in July 2011.

IPC-CH-65B serves as the foundational, 200-page industry guide for cleaning printed boards and assemblies to ensure long-term reliability and prevent failures caused by contamination. The standard outlines essential cleaning technologies, such as aqueous and solvent cleaning, along with validation methods like ROSE and SIR testing to manage residues and maintain compliance.
