Description:
Fourier Transform Infra-red (FTIR) spectroscopy allows chemical fingerprinting, and can be combined with microscopy for small-area analyses. Materials can be identified by comparison with libraries of reference spectra. Solder flux residues can cause poor adhesion and bond strength at contacts resulting in circuit board failure (Copyright QinetiQ).
