The two rows of holes (labelled #3) are test points used during the manufacture of this USB memory key. Testpoints on a printed circuit board (labelled E34, E35, E36, …) next to teardrop vias. A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals. [1]
HP computer products which used HP-IB included the HP Series 80, HP 9800 series, [23] the HP 2100 series, [24] and the HP 3000 series. [25] HP computer peripherals which did not utilize the RS-232 communication interface often used HP-IB including disc systems like the HP 7935. Some of HP's advanced pocket calculators of the 1980s, such as the ...
The cap is red on ThinkPads, but is also found in other colors on other machines. It may be gray, pink, black or blue on some Dell models, blue on some HP/Compaq laptops, and green or gray on most Toshiba laptops produced before the 2000s. Button configurations vary depending on vendor and laptop model.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid.
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]
4+4-pin For the purpose of backwards compatibility, some connectors designed for high-end motherboards and processors, more power is required, therefore EPS12V has an 8-pin connector. 4-pin peripheral power connector 4-pin Peripheral power connectors: These are the other, smaller connectors that go to the various disk drives of the computer ...
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
