Metal Castings

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 […]

Sensor Failures

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 […]

EDS Analysis on EEPROM Devices

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 […]

Possible Bromine on Electrolytic Capacitors

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 […]
