Guidance on choosing between ultrasonic cleaning, vapor degreasing, or spray-in-air systems based on the complexity of the assembly. Verification Methods: Techniques for testing cleanliness, such as the Resistivity of Solvent Extract (ROSE) test or Ion Chromatography. Integration with Other IPC Standards
💡 If you decide to clean a "no-clean" process, you must do it completely. Partial cleaning is often worse because it redistributes ionic materials into hard-to-reach areas. Choosing the Right Method ipc-ch-65 pdf
You cannot effectively clean an assembly without knowing exactly what is on it. The handbook classifies residues into three major threats:
Techniques for evaluating the effectiveness of the cleaning process (e.g., ionic chromatography, surface insulation resistance). How to Obtain the IPC-CH-65B PDF Summarize the latest affecting PCB cleaning
This consolidation was driven by two major industry shifts: the move from solvent-based to water-based (aqueous) cleaning and the transition to . Higher reflow temperatures used in lead-free processes have fundamentally changed the nature of solder residues, making them more difficult to remove and necessitating updated guidance. Key Content of the IPC-CH-65B PDF
Elias typed: System Status?
Released in July 2011, , is a comprehensive document that consolidates the electronics industry’s accumulated knowledge on cleaning PCBs. It serves as a single, definitive guide to cleaning, replacing the need to consult multiple, outdated documents. Consolidation of Standards
