Choosing a cleaning process for electronic assemblies depends on several factors, including the type of contamination, component structure, cleanliness requirement, production volume, and factory conditions. Flux residues, oils, particles, and other contaminants may require different cleaning approaches depending on the application.

Assemblies with low stand-off components, narrow gaps, or complex geometries often require stronger penetration and more controlled drying performance. In other cases, production efficiency, water-free processing, wastewater restrictions, or compatibility with specific materials may also affect the process choice. A suitable cleaning process should match both the technical requirement of the product and the practical condition of production.
