CHARACTERIZATION OF FLUX RESIDUESAuthor: Mary Ann Nailos
Company: Process Sciences
Date Published: 9/12/1999 Conference: SMTA International
Choosing the right test method will depend on identification of the residue type. Ionic residues can be quantified using an Ionic Contamination test saystem such as an OmegameterTM Quantification and identification is made using an Ion Chromatograph. A description of each piece of equipment and the advantages and disadvantages of each will be discussed. Organic residues are harder to identify and quantify. A number of test methods including FTIR, SEM/EDAX, Auger surface analysis and UV/VIS spectrophotometry will be discussed for both qualitative and quantitative analysis of these types of residues. At the end of the presentation the audience should have a better understanding of flux residues and the methods used for their detection and quantification.
Key words: Flux residues, contamination, Ion Chromatography, SEM/EDAX, FTIR, Auger.
