Failure Analysis on MLCCs

Failure Analysis on MLCCs

Gideon Analytical Laboratories received two multilayer ceramic capacitors (MLCCs)for failure analysis. Multilayer ceramic capacitors are fixed value capacitors in which the ceramic is acting as the dielectric material. It is made up of two or more alternating layers of ceramic and a metal layer acting as the electrodes. There are various types of materials that could function as the dielectric in a capacitor, for example, glass, porcelain, paper, or mica. They were not EU ROHS compliant.
NAND Gate

NAND Gate

Gideon Analytical Laboratories received one failed Texas Instruments quad dual input 14-pin hermetic dual-in-line ceramic JM38510/05001BCA NAND gate for electrical component failure analysis. A NAND gate is a logic gate which produces an output that is false only if all its inputs are true; thus its output is a complement to that of the AND gate. A low (0) output results only if both the inputs to the gate are high (1); if one or both inputs are low (0), a high (1) output results.
RNC70H1963FS Resistor Failure

RNC70H1963FS Resistor Failure

Gideon Analytical Laboratories received an RNC70H1963FS resistor for electronic failure analysis. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. They are typically constructed of metal wire or carbon and engineered to maintain a stable resistance value over a wide range of environmental conditions. Resistors are rated both in terms of their resistance (ohms) and their ability to dissipate heat energy (watts).
Vishay 5962-9562301Q3A, Integrated Circuit Failure Analysis

Vishay 5962-9562301Q3A, Integrated Circuit Failure Analysis

Gideon Analytical Laboratories received two integrated circuits for failure analysis. Integrated circuits (ICs) are an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices (like transistors and diodes) and passive devices (like capacitors and resistors) and their interconnections are built upon a thin substrate of semiconductor material. One was a Texas Instruments 5962-9861201QXA and the other was a Vishay 5962-9562301Q3A. The Texas Instruments 5962-9861201QXA was a DSP fixed-point 16-Bit 40MHz 20MIPS 132-Pin CFPAK.
Linear Microcircuit Modular Hybrid

Linear Microcircuit Modular Hybrid

Gideon Analytical Laboratories received one linear microcircuit modular hybrid FK23009 for electronic failure analysis. A hybrid integrated circuit (HIC) is a miniaturized electronic circuit constructed of individual devices, such as semiconductors and passive components like resistors or inductors, and typically encapsulated in epoxy. The hybrid microcircuit is used in military and communications applications and is excellent for creating custom analog circuits, such as amplifiers and modulators. Thick film technology is often used as the interconnecting medium for hybrid integrated circuits.
Xilinx TQG144 Packages

Xilinx TQG144 Packages

Gideon Analytical Laboratories received four working and four defective integrated circuit packages for failure analysis. They were Xilink TQG144 packages. Integrated circuit packaging is the final stage of semiconductor device fabrication, in which the tiny block of semiconducting material is encased in a supporting case that prevents physical damage or corrosion. These integrated circuit packages come in a variety of styles including surface mount, chip carriers, and pin grid arrays. Once the packages are fabricated, they are mounted and connected to a printed circuit board (PCB).
Failed 1210 MLCCs

Failed 1210 MLCCs

Gideon Analytical Laboratories received three 1210 Multi-Layer Ceramic Capacitors (MLCC) for analysis. Multilayer ceramic capacitors are fixed value capacitors in which ceramic the material acting as the dielectric. It is made up of two or more alternating layers of ceramic and a metal layer acting as the electrodes. There are various types of materials that could function as the dielectric in a capacitor, for example, glass, porcelain, paper, or mica. The MLCCs were from a Time Hub printed circuit board (PCB).
Microsemi DZ771215A diode

Microsemi DZ771215A diode

Gideon Analytical Laboratories received a failed Microsemi DZ771215A 10 watt diode for failure analysis. Two working devices were provided for comparison. A diode is an electric device that has two electrodes (anode and cathode) and that only allows current to flow in one direction, resisting current in the other direction. Diodes are used copiously as rectifiers, which convert alternating current (AC) to direct current (DC) to change the amplitude of the signal in proportion to its voltage in the circuit.
Thermal Damage to MLCC

Thermal Damage to MLCC

Gideon Analytical Laboratories received one MLCC on a DC input noise filter PCB on which to perform failure analysis. MLCCs (Multi-Layered Ceramic Capacitors) are extremely ubiquitous in the electronics field; it was estimated that around 1000 billion are produced per year. The MLCC has severe thermal damage but was still intact to the pads via the termination solder connections. Analytical services were provided. The MLCC could not be cut from the PCB and the PCB could not be cut because of the fragile nature of the condition.
Tusonix Pi Filters

Tusonix Pi Filters

Gideon Analytical Laboratories received several Tusonix Pi filters that were failing in the field. Capacitor-input filters (also known as Pi filters) are a type of electronic filter used to remove unwanted frequencies from a signal. Pi filters are primarily constructed of two capacitors and an inductor and are used in situations where the ripple of a signal or the AC and DC currents within the signal are found to interfere with each other.
