Gideon Analytical Analytical Laboratories received one On Semi MC14070BG CMOS SSI in a SOEIAJ-14 package, with the 15V supply line pulled down to 3.5V. The MC14070B quad exclusive OR gate and the MC14077B quad exclusive NOR gates are constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. These complementary MOS logic gates find primary use where low power dissipation and/or high noise immunity is desired. The CMOS is a Complementary metal–oxide–semiconductor, which is a technology for constructing integrated circuits.
Gideon Analytical Laboratories received several rigid-flex printed circuit boards (PCBs), which containedTexas Instruments TPS54360 DC-DC converter and Micro Commercial Components Schottky rectifier SK810L-TP. The TI TPS54360 is a 60 V, 3.5 A, step down regulator with an integrated high side MOSFET. The device survives load dump pulses up to 65V per ISO 7637. Current mode control provides simple external compensation and flexible component selection. The SK810L-TP is Rohs compliant, has high current availability, and is for surface mount application.
Gideon Analytical Laboratories received two components for analysis. We received one 10TTS08S phase control silicon controlled rectifier (SCR) and an FDC6324L integrated load switch. A silicon controlled rectifier (SCR) is a four-layer solid-state current-controlling device. It consists of four layers of semiconductors, which form NPNP or PNPN structures have three P-N junctions labeled J1, J2 and J3, and three terminals. The anode terminal of an SCR is connected to the p-type material of a PNPN structure, and the cathode terminal is connected to the n-type layer, while the gate of the SCR is connected to the p-type material nearest to the cathode.
Gideon Analytical Laboratories received one section of the anode electrode to identify the black marking on the copper foil. This anode electrode is used in Lithium-ion batteries. A Lithium-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Lithium-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery.
Gideon Analytical Laboratories received a Printed Circuit Board (PCB) with contamination on several capacitor sleeves, connector pins, and an oscillator. An electrolytic capacitor is a capacitor whose anode (+) consists of pure aluminum foil with an etched surface, covered with a uniformly very thin barrier layer of insulating aluminum oxide, which operates as a dielectric. The electrolyte, which covers the rough surface of the oxide layer, operates as the second electrode, the cathode (-).
Gideon Analytical Laboratories receivedthree Fairchild RFP40N10 power MOSFETs. A MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle significant power levels.Compared to the otherpower semiconductor devices, for example, an insulated-gate bipolar transistor (IGBT) or athyristor, its main advantages are highswitchingspeed and good efficiency at low voltages. It shares with the IGBT an isolated gate that makes it easy to drive. They can be subject to low gain, sometimes to degree that the gate voltage needs to be higher than the voltage under control.
Gideon received six used IC .33uF K MKP X2 MPX film capacitors with lower than expected capacitance for failure analysis. EMI suppression capacitors are used to suppress any noise from an electronic device by reducing the input impedance of the device. These types of capacitors have 2 classifications, X and Y. The X-type connects line to line. X capacitors have three categories; X1, X2, and X3. These are based on voltage.
Gideon Analytical Laboratories received one IXYSRF DE375-501N21A MOSFET for electronic failure analysis. A MOSFET is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The IXYSRF DE375-601N21A MOSFET has high dv/dt, nanosecond switching, and 50 MHz maximum frequency. The IXYSRF DE375-601N21A MOSFET sent to Gideon Analytical Laboratories had a g-s short.
Gideon Analytical Laboratories received five failed ST Microelectronics BTA16-800 triacs and one good ST Microelectronics BTA16-800 triac for comparison. A triac is a generic trademark for a three terminal electronic component that conducts current in either direction when triggered. Its formal name is bidirectional triode thyristor or bilateral triode thyristor. The goal was to determine the cause of these failures.
Gideon Analytical Laboratories went straight to work conducting failure analysis on theST Microelectronics BTA16-800 triacs.
Gideon received ultra precision calibration resistors. These resistors have a tolerance of .1%. The ultra precision thin film resistors are designed for high precision circuitry. They have excellent stability and reliability over the operating temperature range and low TCR characteristics.
The resistors were running about .3 to .4 ohm too high.
