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.

CAT Advanced Series -
Amperis sl
Description The Advanced CAT Series Analyzers and Timers are stand-alone or PC-controlled digital instruments for circuit breaker status evaluation. Timing channels record arc closing and opening, resistance and auxiliary contacts. The main contact channels can also measure the resistance value of pre-insertion resistors (if present in the breaker). The advanced CAT series records graphs of the opening and closing coil currents and the movements of the moving parts of the high and medium voltage circuit breaker. Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form. The advanced CAT series provides easy selection of different operating modes:

National Technical Systems
The use of Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDS) in the analysis of failure related issues of printed circuit boards (PCBs), assemblies (PCAs), and electronic components (BGA, capacitors, resistors, inductors, connectors, diodes, oscillators, transformers, IC, etc.) is a well-established and accepted protocol. As opposed to or simply in addition to normal optical microscopy, SEM/EDS allows for the “inspection” of areas of interest in a much more informative way.

MIG0603CAP -
EMC Partner AG
The MIG0603CAP consists of two circuits with impulse capacitance 20 µF and 0,25 µF. Both circuits generate a voltage wave shape 1,2/50 µs and are combined in a 4 unit height 19" rack. The generator circuits are defined in IEC 60384-14 and EN 132400. The serial resistors Rs, the impulse capacitor CT, and the load capacitance Cp will be automatically switched when different capacitance ranges are selected on the MIG0603CAP.

NI
96-Channel, 5 V TTL/CMOS, 2.5 mA PXI Digital I/O Module—The PXI‑6508 uses four, 24‑bit programmable peripheral interfaces (PPIs) that can each be divided into three, 8‑bit ports. The PXI‑6508 can interface to peripherals or other computers, and it can operate in either a unidirectional or bidirectional mode and handshake with peripheral equipment. The PXI‑6508 is well suited for applications that require onboard pull-up resistors.

Bender Inc.
Neutral Grounding Resistors (NGRs) are used to limit the maximum ground-fault current. Restriction of fault current lowers hazards and reduces damage done to equipment. High Resistance Grounding (HRG) systems are often used on industrial and critical power applications to maintain system uptime during a first ground fault. HRG systems are also used in tripping applications to help control touch potential on portable loads and improve personnel safety.
