Dell Precision T3600 System Motherboard, used in professional CAD Workstations. Manufactured in 2012. A motherboard (also called mainboard, main circuit board, MB, mobo, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.
The die from an Intel 8742, an 8-bit microcontroller that includes a CPU, 128 bytes of RAM, 2048 bytes of EPROM, and I/O "data" on current chip A circuit built on a printed circuit board (PCB) An electronic circuit is composed of individual electronic components , such as resistors , transistors , capacitors , inductors and diodes , connected ...
Circuit boards contain considerable quantities of lead-tin solders that are more likely to leach into groundwater or create air pollution due to incineration. [ 74 ] Recycling of computer hardware is considered environmentally friendly because it prevents hazardous waste , including heavy metals and carcinogens, from entering the atmosphere ...
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products , available in a singular form and are not to be confused with electrical elements , which are conceptual abstractions ...
The mold forms part of the package. COF: Chip-on-flex: Variation of COB, where a chip is mounted directly to a flex circuit. Unlike COB, it may not use wires nor be covered with epoxy, using underfill instead. TAB: Tape-automated bonding: Variation of COF, where a flip chip is mounted directly to a flex circuit without the use of bonding wires ...
In assembly the bare board is populated (or "stuffed") with electronic components to form a functional printed circuit assembly (PCA), sometimes called a "printed circuit board assembly" (PCBA). [26] [27] In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; the holes keep the components in place.
Part of a radio transmitter used to impress modulation on one amplifying stage. modulation The impression of information on a carrier wave for transmission. monolithic microwave integrated circuit An integrated circuit that operates in microwave frequencies and that can be fabricated by printed circuit board technology. monoscope
