Cleaning Flux Residue under Leadless Components using Objective Evidence to Determine Cleaning Performance

Credits: KYZEN Corporation

Cleanliness is a product of design, including component density, standoff height and the cleaning equipment's ability to deliver the cleaning agent to the source of residue. The presence of manufacturing process soil and incomplete removal of cleaning fluids can hinder the functional lifetime of the product (...)

This research project is designed to study visual flux residues trapped under the bottom termination of leadless components. This paper will research a non-destructive visual method that can be used to study the cleanability of solder pastes, cleaning material effectiveness for the soil, cleaning machine effectiveness and process parameters needed to render a clean part.
