Analysis via Fourier Transform Infrared Spectroscopy (FTIR)

National Technical Systems (NTS)

Fourier Transform Infrared Spectroscopy (FTIR) is a standard technique used in the identification of contaminating materials on the surface of printed circuit boards (PCBs) and around the leads of electronic components (BGA, capacitors, resistors, inductors, connectors, diodes, oscillators, transformers, IC, etc.) on printed circuit assemblies (PCAs). Additionally, FTIR can be used for “simpler” identifications, such as determining a specific type of plastic or rubber compound.
