It explains how different flux types (water-soluble, rosin-based, no-clean) interact with cleaning chemistries and board finishes.
The dominant modern method. It uses water-based chemistries and is highly effective on water-soluble and many no-clean fluxes.
Proper cleaning prevents field failures caused by residue-induced corrosion or electrochemical migration. Process Control: ipc-ch-65 pdf
Good for removing flux under low-stand-off components.
If you are looking for the up-to-date standard, you should refer to: Time of exposure
The standard emphasizes that cleaning is not just about the chemistry, but the process parameters: Temperature of cleaning agents. Time of exposure.
Are you focused on or corrosion prevention ? IPC-CH-65B replaced several older documents
For decades, the electronics industry relied on various individual standards for specific cleaning tasks. IPC-CH-65B replaced several older documents, including: : Post-Solder Solvent Cleaning IPC-SA-61A : Post-Solder Semi-Aqueous Cleaning IPC-AC-62A : Post-Solder Aqueous Cleaning IPC-SM-839 : Guidelines for Post-Solder Cleaning
Component cleanliness is a critical factor in modern electronics manufacturing. Residual contaminants on printed circuit boards (PCBs) and components can cause premature field failures, electrochemical migration, and electrical shorts.
