Appendix B: Cleanliness Testing Methods
ROSE (Resistivity of Solvent Extract): Quick, cheap, but non-specific.
Ion Chromatography (IC): Expensive but definitive for ionic species (Cl-, Br-, Na+, K+).
SIR (Surface Insulation Resistance): The ultimate test for electrochemical reliability (target > 10^8 ohms after conditioning).
IPC-CH-65B provides comprehensive guidelines for cleaning printed circuit boards, covering contamination sources, soldering, and environmental factors in accordance with industry standards. The 2011 revision updates cleaning processes to address lead-free materials and no-clean flux residues. Purchase the document via ANSI Webstore ANSI Webstore ipc-ch-65 pdf
