physically changeable bit
printed circuit board, also called electronics board
polychlorinated biphenyl
program control block
thin board to which electric components and wires are attached to one side and printed circuits are attached to the other
in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. The commercial product, a mix of several PCB isomers, is a colourless, viscous liquid that is almost insoluble in water, does not degrade under high temperatures, and is a good electrical insulator (see dielectric). PCBs became widely used as lubricants, heat-transfer fluids, and fire-resistant dielectric fluids in transformers and capacitors in the 1930s and '40s. In the mid 1970s they were found to cause liver dysfunction in humans and came under suspicion as carcinogens; their manufacture and use were consequently restricted in the U.S. and many other countries, though illegal dumping by manufacturers continued. They persist in the environment and have entered the food chain, causing great harm especially to invertebrates and fish
{i} poisonous chemical substance
(n) Acronym for printed circuit board, a rigid board typically made from fiberglass, approximately 060" thick, and used for mounting electronics components as part of a larger assembly This board, also called a printed wiring board (PWB), has wiring patterns formed by traces of a conductor, such as copper, fused to the board The wiring pattern is created either by depositing the conductor on the board or by starting with a solid film of the conductor and etching away what is not needed
(Printed Circuit Board) - Generally flat, multi-layer boards made of fiberglass with electrical traces The surface and sub layers use copper traces to provide electrical connections for chips and other components Examples of PCBs include: mother-boards, SIMMs, and credit card memory
Abbreviation for printed circuit board Also referred to as PWB (printed writing board)
Printed circuit board Board that contains layers of circuitry that is used to connect components to a system
Polychlorinated Biphenyl, a synthetic, organic chemical once widely used in electrical equipment, specialized hydraulic systems, heat transfer systems, and other industrial products Highly toxic and a potent carcinogen Any hazardous wastes that contain more than 50 parts per million of PCBs are subject to regulation under the Toxic Substances Control Act
Printed Circuit Board; board upon which there are layers of printed circuits where DRAMs can be attached with solder so that memory can be accessed
Printed Circuit Board; an insulating card with one or more layers of copper interconnections onto which are soldered integrated circuit packages and other electronic components PCBs are usually plugged into sockets that may be interconnected through a wire bus
(Printed Circuit Hoard)A component made up of layers of copper and fiberglass; the surface of a PCB features a pattern of copper lines, or "traces," that provide electrical connections for chips and other components that mount on the surface of the PCB Examples: motherboard, SIMM, credit card memory, and so on
Printed Circuit Board or Polychlorinated Biphenol
printed circuit board; an epoxy glass and metal composite on which circuits are etched and to which active, passive and hardware components are attached
Abbreviation for Printed Circuit Board An insulating material with attached electrical conductors, and usually, various types of electronic devices
Printed Circuit Board, the base on which most electronics is built
(Printed Circuit Board) - Generally flat, multi-layer boards made of fibreglass with electrical traces The surface and sublayers use copper traces to provide electrical connections for chips and other components Examples of PCBs include: motherboards, SIMMs, and credit card memory
polychlorinated biphenyl Commonly used in electrical transformers May cause cancer as well as problems with the skin, liver, and with hearing and vision
Printed Circuit Board
(Printed Circuit Board) : A component made up of layers of copper and fiberglass; the surface of a PCB features a pattern of copper lines, or "traces," that provide electrical connections for chips and other components that mount on the surface of the PCB Examples: motherboard, SIMM, credit card memory, and so on
printed circuit board, or PC board A piece of phenolic or glass-epoxy board with copper clad on one or both sides The portions of copper that aren't needed are etched off, leaving "printed" circuits which connect the components
