The component is submerged in a mixture of isopropyl alcohol (IPA) and deionized water. The change in the liquid's electrical resistivity is measured.
The most current version, often referenced as , provides updated information on: Lead-free solder processing. No-clean soldering flux challenges. Advanced environmentally friendly cleaning chemistries. Improved cleanliness assessment methods. Why You Need the IPC-CH-65 Guidelines
While there is no standalone “IPC‑CH‑65 certification,” the standard is referenced in many broader IPC training programs. Courses covering cleanliness requirements often use IPC‑CH‑65 alongside IPC‑A‑610 and J‑STD‑001 as the basis for instruction. ipc-ch-65 pdf
Some essential aspects of IPC Section 65 include:
The primary goal of IPC-CH-65B is to help engineers navigate the relationship between materials, processes, and contaminants to ensure the reliability of electronic assemblies. The component is submerged in a mixture of
