Flux Residue Issues Countermeasure Guide | Explanation of Cleaning Methods and Evaluation Techniques

A technical documentation collection that explains everything from the risks of flux residue to cleaning and evaluation in one book.

This document is a technical compilation that systematically summarizes the mechanisms of flux residue generation on electronic substrates, associated defect risks, cleaning methods, and evaluation techniques after cleaning. It explains the causes of issues such as decreased insulation resistance, migration, corrosion, and connection failures due to flux residues, and introduces the objectives of substrate cleaning (flux cleaning), representative cleaning systems, and key points for selecting cleaning processes. Furthermore, it clearly organizes evaluation methods to confirm cleaning quality, including visual inspection, ion residue measurement, ion chromatography, FT-IR, SEM-EDX, XPS, and surface insulation characteristic evaluation. This book is recommended for assembly engineers and quality assurance personnel considering measures against flux residues, as well as the introduction and improvement of cleaning processes and quality enhancement.
