IPC-CH-65B was a crucial handbook providing guidance on the cleaning of printed circuit board assemblies (PCBs). It addressed the growing concerns about contaminants (flux residues, dust, oils) that can lead to corrosion, dendrite growth, and electrical failures. The document was particularly vital during the transition from CFC-based solvents to aqueous and no-clean processes. ipc-ch-65 pdf

IPC-CH-65 (IPC-CH-65A) remains the definitive guide for cleaning electronic assemblies, even though it was last revised in 2007. It is essential for any facility producing high-reliability electronics where residue-related failures (leakage current, dendritic growth) cannot be tolerated.
The handbook covers various cleaning methods, including aqueous (water-based), semi-aqueous, and solvent cleaning. It also addresses environmental impacts, material selection, and process control.
