FEI Quanta Environmental Scanning Electron Microscope
CALCE houses a state-of-the-art FEI Quanta Environmental Scanning Electron Microscope (ESEM) with advanced Energy Dispersive Spectroscopy (EDS), Digital Imaging, and in-situ Heating/Cooling capabilities. The ESEM can be operated in a high vacuum-high accelerating voltage mode (standard SEM mode) very high magnification (>100KX) and high resolution or low vacuum high accelerating voltage mode.
These three modes (high-vacuum, low-vacuum and ESEM) accommodate the widest range of samples and allow CALCE researchers to examine unprepared, uncoated specimens in their natural environment. CALCE also possesses the added capability to conduct dynamic characterization like wetting, drying, absorption, melting, corrosion, and crystallization using the ESEM.
OKOS NDT CF-300 Scanning Acoustic Microscope
The OKOS NDT CF-300 Scanning Acoustic Microscope is used to image a specimen’s internal features. Scanning Acoustic Microscopy (SAM) is highly sensitive to the presence of delaminations, and can detect delaminations of sub-micron thickness, which are difficult to detect using X-ray radiography. SAM is an important tool for detecting popcorn cracking/delamination, die attach voiding, evaluating flip chip underfill integrity, and lid seal integrity in hermetically sealed packages.
The Scanning Acoustic Microscope can operate at frequency ranges between 2.25 to 230 MHz.
Lansmont Drop Tower
Used to induce shock loads to PCBs. The Lansmont Drop Tower can achieve ~10,000g, and wih the addition of a dual mass shock amplifier (DMSA) can achieve ~35,000g. Pulse profile (quick high amplitude impulse vs. longer shorter amplitude impulse) can be controlled by changing the medium of contact in the drop tower.
TA Instruments - Thermal Analysis – DSC 250 Differential Scanning Calorimeter
The DSC is used for investigation, selection, comparison, and end-use performance evaluation of materials in research, quality control and production applications. DSC can be applied to techniques such as glass transitions, “cold” crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability. DSC performs calorimetric measurements as a function of temperature.
The TA Instruments DSC 250 is equipped with a cooling system providing operation from -90℃ (183 °K). The instrument is typically operated to 400℃. Sample capsules include hermetically-sealed and non-sealed pans. Typical sample sizes are less than 25 mg.
TA Instruments Dynamic Mechanical Analyzer 850
The DMA850 measures mechanical/rheological properties of a material as a function of time, frequency, temperature, stress, and strain. Such rheologic properties includes modulus, viscosity, creep, stress relaxation, and stress/strain behavior, over a range of temperatures.
