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-65 does not operate in a vacuum. It is part of a broader family of IPC standards that provide a complete framework for electronics manufacturing quality. Here's how it fits in:

Uses water-based solutions, often with detergents or saponifiers, to remove polar and non-polar contaminants. It is widely favored for its environmental benefits and effectiveness with water-soluble fluxes.

A recent 2025 paper on Cleanliness Process Development on ResearchGate references IPC-CH-65B specifically regarding flux residue solubility and cleaning chemistry matching. What the Topic Covers

The IPC-CH-65B PDF provides the answer to this problem. It is not a strict, prescriptive specification (it does not, for example, set hard pass/fail limits for every situation). Instead, it is a that provides the knowledge and the framework for manufacturers to develop their own, validated cleaning processes.

While focuses on how to clean, you should also reference:
