Test Methods to Validate Acceptable Levels of Flux and Other Process Residues on Production Assemblies
Electronics manufacturers aim to minimize the amount of flux residues. Solder flux residues constitute a significant source of ionic contamination on the manufactured PCBAs, and the activator type in the flux determines their corrosiveness. The risk occurs on low standoff components, such as the QFN, due to blocked flux outgassing channels. The second risk is the number of soldering process steps used to build the assembly. Selective soldering, wave soldering, manual, and rework soldering can spread flux residues across the assembly. Pockets of active residue can be present when the flux is not fully heat-activated. For high reliability, the best practice is to clean the assembly.
This webinar will teach best practices for qualifying and validating acceptable electrical hardware performance. The methods taught during this presentation can be used to meet the requirements of IPC J-STD-001H ~ Section 8: Cleanliness.
