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, such as flux residue, incompletely activated flux, incompletely cured solder masks, debris from handling and processing fixtures, and incomplete removal of cleaning fluids can hinder the functional lifetime of the product. Contaminates trapped under a component are more problematic to failure. Advanced test methods are needed to obtain "objective evidence" for removing flux residues under leadless components.Cleaning process performance is a function of cleaning capacity and defined cleanliness. Cleaning performance can be influenced by the PCB design, cleaning material, cleaning machine, reflow conditions and a wide range of process parameters.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.

STI's Mark McMeen, VP, Engineering Services, will have a special presentation on How does one collect "Objective Evidence" to meet the new J-STD-001 Section 8.1 on electronic assembly cleanliness? The presentation take place at STI Electronics Inc.'s facility in Madison, AL on March 26, 2020 at 3 p.m. and will explore why this IPC standard came about and why the current "ROSE" test methodology is not enough for today's advanced designs. It will explore different tools and techniques as well as discuss how to gather objective evidence needed to meet the specification. There will be an actual demonstration of the equipment and test reports that are generated by the SIR test equipment along with the actual hardware that generates the test data that supports "Objective Evidence" for review. Do you know how "clean or dirty" your electronic manufacturing process and resulting hardware/assemblies are at completion?

The latest highest reliability requirements demand a high performance electroless nickel and immersion gold (HP ENIG). The new IPC specification 4552A has refocused the industry with reference to nickel corrosion. The interpretation of the existing specification, that judges corrosion on 3 levels, is complex and if misinterpreted can lead to phantom failures. An obvious way to avoid any potential misinterpretation is to eradicate any evidence of corrosion completely.
