For engineers, quality managers, and production technicians, accessing the is the first step toward implementing robust cleaning processes. What is IPC-CH-65B?
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.
Developed by IPC, the Association Connecting Electronics Industries, the IPC-CH-65 series has served for decades as the primary repository of knowledge for cleaning printed circuit boards (PCBs) and electronic assemblies. The current definitive version, , represents a major revision that was released in July 2011. It was created to address the complexities introduced by modern technologies, including lead‑free soldering, no‑clean flux chemistries, and environmentally friendly materials.

Perhaps the most vital contribution of the IPC-CH-65B is its focus on process control and validation. It moves the industry away from a "one-size-fits-all" mentality, instead encouraging manufacturers to prove that their specific process works for their specific design. By referencing testing standards like Ion Chromatography and Resistivity of Solvent Extract (ROSE), the guideline ensures that "clean" is a measurable metric rather than a subjective opinion. This data-driven approach is essential for industries where failure is not an option, such as aerospace, medical electronics, and automotive safety systems.
Water-based systems (often with saponifiers) for water-soluble fluxes. Solvent Cleaning: Ideal for heavy-duty residue removal.
Learn about different methods for measuring ionic contamination (e.g., Ion Chromatography) and surface insulation resistance (SIR).
