Gideon Analytical Laboratories received six United Chemi-Con KMG series 400V 22uF 6U capacitors for the specific purpose of determining whether or not they had the presence of chlorides.
The analysis was performed using SEM-EDS. The SEM-EDS system gave elemental analysis in relation to the intensity of the element at a specific wavelength or energy level (Kev). SEM-EDS is an analytical technique used for the elemental analysis or chemical characterization of a sample.
Gideon Analytical Laboratories received several high-intensity discharge lamp (HID) assemblies for determination and cause of a white powder-like substance on the inside of the lens housing. The white powder diminishes the reflective properties of the light and overall effectiveness. HID lamps are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.
Gideon Analytical Laboratories received 22 EEPROM devices for analysis of the lead plating. EEPROM stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed. EEPROMs are organized as arrays of floating-gate transistors. EEPROMs can be programmed and erased in-circuit, by applying special programming signals.
Gideon Analytical Laboratories received two Fairchild RV4140A Ground Fault Interrupt Controller/Monitors in eight-pin SOIC packages. The Fairchild RV4140A is low power controller for AC outlet appliance leakage circuit interrupters. These devices detect hazardous current paths to ground such as an appliance falling into water. The interrupter then opens the circuit before a harmful or lethal shock occurs. A SOIC package is a surface-mounted integrated circuit (IC) package which occupies an area about 30 to 50 % less than an equivalent dual in-line package (DIP), with a typical thickness that is 70 % less.
Gideon Analytical Laboratories received two metal castings. One was a cylinder and the other was an insert to the bottom of the cylinder. Metal means a process, in which liquid metal is poured into a mold, that contains a hollow cavity of the desired shape, and then allowed to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
Gideon Analytical Laboratories received two power supply boards with components. The supplies were thought to have contamination, possibly bromine, causing corrosion or failing the electrolytic capacitor. The term electrolytic capacitor in a generic term for three different capacitors, which include aluminum electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors. All electrolytic capacitors are polarized capacitors whose anode is made of a particular metal on which an insulating oxide layer forms by anodization, acting as the dielectric of the electrolytic capacitor.
Gideon Analytical Laboratories received Printed Circuit Boards (PCBs) with Ralec RTT20132JTE resistors. A PCB is a mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. A resistor a passive two-terminal electrical component that implements electrical resistance as a circuit element.
Gideon Analytical Laboratories received two image sensors with high impedance on the connector between pins 4 and 5, measuring 10 KHz. An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation.
Gideon Analytical Laboratories received two newly designed ST Microelectronics ASC T6108 Triacs in a TO-220AB package. A TRIAC is a three terminal semiconductor device for controlling current.Its formal name is bidirectional triode thyristor or bilateral triode thyristor. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The goal was to determine if these ASC T6108 Triacs were reliable.
Gideon Analytical Laboratories received twoST Microelectronics BTA06-600B and two Little fuse Q6006L5 triacs in TO-220AB packages. Inspection of the die for microcracking was requested.
We were happy to fulfill our client’s request. There were no mechanical marks on either device and the lead frame was tin-plated. The Triacs were electronically tested on a curve tracer. A curve tracer is a specialized piece of electronic test equipment used to analyze the characteristics of discrete semiconductor devices such as diodes,transistors, and thyristors.
