In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates .
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
Closeup of a touchpad on an Acer CB5-311 laptop Closeup of a touchpad on a MacBook 2015 laptop. A touchpad or trackpad is a type of pointing device.Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.
However, the recalibration can also allow brief periods of 'drifting' (movement of the pointer while the user is not moving the pointing stick). [7] In practice, if the re-calibration interval is set too short and if the user applies moderately consistent pressure to the stick for such an interval, this method results in an incorrect zero point.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
12VHPWR adapter (12VHPWR output on the left, four 8-pin inputs on the right) supplied with Nvidia RTX 4090 cards. The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors ...
A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer.
Variety of loose pogo pins and pogo pins in 3-pin assembly holders and with Pick and Place caps Sectional drawing of a pogo pin, showing the plunger, barrel, and spring. A pogo pin or spring-loaded pin is a type of electrical connector mechanism with spring plungers that is used in many modern electronic applications and in the electronics testing industry. [1]
