It is used as a backbone to connect several printed circuit boards together to make up a complete computer system.

Backplanes commonly use a printed circuit board but wire wrapped backplanes have also been used in minicomputers and high reliability applications.

On large machines, CPUs require one or more printed circuit boards.

With this improvement more complex and reliable CPUs were built onto one or several printed circuit boards containing discrete ( individual ) components.

There are several companies in the United States that charge a small fee to collect CRTs, then subsidize their labor by selling the harvested copper, wire, and printed circuit boards.

In keeping with the original concept, the Nova was based on two printed circuit boards, one for the CPU and another for various support systems.

Components are generally intended to be connected together, usually by being soldered to a printed circuit board ( PCB ), to create an electronic circuit with a particular function ( for example an amplifier, radio receiver, or oscillator ).

Electronic design automation software programs include schematic capture programs and printed circuit board design programs.

Most modern day electronics now use printed circuit boards made of materials such as FR4, or the cheaper ( and less hard-wearing ) Synthetic Resin Bonded Paper ( SRBP, also known as Paxoline / Paxolin ( trade marks ) and FR2 )-characterised by its light yellow-to-brown colour.

* PCBLAYOUT to describe a printed circuit board

Small inductors can be etched directly onto a printed circuit board by laying out the trace in a spiral pattern.

In electronic systems, printed circuit boards are made from epoxy plastic and fibreglass.

Unlike " dome switch " keyboards, the pattern consists of two D-shaped capacitor pads for each switch, printed on a printed circuit board ( PC board ) and covered by a thin, insulating film of soldermask which plays the role of a dielectric.

* Laser Drillable Prepreg, printed circuit board material

For each computer built, all of these had to be placed and soldered onto printed circuit boards, and often multiple boards would have to be interconnected in a chassis.

A motherboard ( sometimes alternatively known as the mainboard, system board, planar board or logic board ) is a printed circuit board ( PCB ) found in all modern computers which holds many of the crucial components of the system, such as the central processing unit ( CPU ) and memory, and provides connectors for other peripherals.

Prior to the advent of the microprocessor, a computer was usually built in a card-cage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires ; in very old designs the wires were discrete connections between card connector pins, but printed circuit boards soon became the standard practice.

The Central Processing Unit, memory and peripherals were housed on individual printed circuit boards which plugged into the backplate.

A CPU socket or slot is an electrical component that attaches to a printed circuit board ( PCB ) and is designed to house a CPU ( also called a microprocessor ).

* Occam Process, a method for the manufacture of populated, printed circuit boards

By 1962, several companies were producing modular potted packages that could be plugged into printed circuit boards.

This procedure is comparable to a high precision version of the method used to make printed circuit boards.

That is, the printed circuit boards plugged into a backplane connector.

This ensures continuity of the circuit between the moving contacts on the armature, and the circuit track on the printed circuit board ( PCB ) via the yoke, which is soldered to the PCB.

* Package / enclosure – open, touch-safe, double-voltage for isolation between circuits, explosion proof, outdoor, oil and splash resistant, washable for printed circuit board assembly

* Stray magnetic linkage between coils of adjacent relays on a printed circuit board.

The top of the board is typically a layer of acrylic with some form of graphic designed to attract attention, showcase artwork, or serve the purpose similar to that of any other form of printed media.

A soldered joint used to attach a wire to the pin of a component on the rear of a printed circuit board.

The last two metrics appear for example in routing a machine that drills a given set of holes in a printed circuit board.

* Car Wars-( Steve Jackson Games, 1982 )-initially printed as a board game, it quickly evolved to incorporate elements of miniatures games.

* The poster for the film was done by artist Kelly Freas, who put a number of subliminal images into the painting ; Freas also printed the faux film titles seen on the producers ' bulletin board.

While PEDOT ( poly ( 3, 4-ethylenedioxythiophene )) is mainly used in antistatic applications and as a transparent conductive layer in form of PEDOT: PSS dispersions ( PSS = polystyrene sulfonic acid ), polyaniline is widely used for printed circuit board manufacturing – in the final finish, for protecting copper from corrosion and preventing its solderability.

Topics include, but are not limited to, materials and finishes ; electrostatic discharge requirements ; printed wiring boards and assemblies ; connectors, wire, and cable ; product marking and identification ; and qualification test procedures.

Parts for military and aerospace applications were packaged in flat packs, a form of surface-mount package, with leads suitable for welding or soldering to printed circuit boards.

Its report, produced in February 1999, estimated that it had taken " more than 100, 000 pages of reports, statements, and other written or printed documents " and concluded that the original Metropolitan Police Service investigation had been incompetent and that officers had committed fundamental errors, including: failing to give first aid when they reached the scene ; failing to follow obvious leads during their investigation ; and failing to arrest suspects.

This leads to all the tankobon covers being gold or silver and then color printed over it.

Fuses designed for soldering to a printed circuit board have radial or axial wire leads.

The KWR-37 weighed 100 pounds ( 45 kg ) and contained some 500 subminiature vacuum tubes, whose leads were soldered to printed circuit boards.

Subminiature tubes with long wire leads, introduced in the 1950s, were often soldered directly to printed circuit boards.

They were used, for example, in laying out printed circuit boards with the spacing of leads from integrated circuits as one-tenth of an inch.

Through-hole technology, also spelled " thru-hole ", refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards ( PCB ) and soldered to pads on the opposite side either by manual assembly by hand placement or by the use of automated insertion mount machines.

These leads connect, usually soldered to a printed circuit board, to create an electronic circuit ( a discrete circuit ) with a particular function ( for example an amplifier, radio receiver, or oscillator ).
