LED art - Circuit board

1 The visible side of the etched circuit board can be constructed to flash in a variety of ways, especially where there are multiple LEDs in multiple

colours

Circuit board

1 Printed circuit boards are used in all but the simplest electronic products.

Alternatives to PCBs include wire wrap and point-to-point construction. PCBs are more costly to design but

allow automated manufacturing and assembly. Products are then faster and cheaper to manufacture, and

potentially more reliable.

Circuit board

1 A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board

assembly or PCB assembly (PCBA)

Circuit board - Design

1 Printed circuit board artwork generation was initially a fully

manual process done on clear mylar sheets at a scale of usually 2 or 4

times the desired size

Samsung Electro-Mechanics - Printed circuit boards (PCBs)

1 The purpose of printed circuit boards (PCBs) is to transmit electrical

signals among various electronic parts and components. Microcircuits

and build-up technologies are

Chamfer - In printed circuit board (PCB) design

1 In printed circuit board (PCB) designing, a chamfer occurs when a right-angled edge is eliminated from the tracks, to strengthen the places where a track meets another at a

right angle. It also reduces reflections; important for high-

frequency design.

Ground plane - Printed circuit boards

1 A ground plane on a printed circuit board (PCB) is a large area or layer of copper foil connected to the circuit's

ground (electricity)|ground point, usually one terminal of the power

supply. It serves as the return path for electric current|current from

many different components.

Ground plane - Printed circuit boards

1 A power plane is often used in addition to a ground plane in a

multilayer circuit board, to distribute DC power to the active devices. The two facing areas of copper create a

large parallel plate decoupling capacitor that prevents noise from being coupled from one circuit to

another through the power supply.

Design for manufacturability - Design for manufacturability for printed circuit boards (PCB)

1 In the Printed circuit board|PCB design process, DFM leads to a set design guidelines that attempt to

ensure manufacturability. By doing so, probable production problems

may be addressed during the design stage.

Printed circuit boards

1 Printed circuit boards are used in all but the simplest electronic products. Alternatives to PCBs include wire wrap and point-to-point construction. PCBs require the additional

design effort to lay out the circuit but manufacturing and assembly can be

automated. Manufacturing circuits with PCBs is cheaper and faster than with other wiring methods as components are mounted and wired with one single part. Furthermore,

operator wiring errors are eliminated.

Printed circuit board milling

1 By contrast, in the chemical etch process, the quality of a circuit board

depends on the accuracy and/or quality of the photomasking and the

state of the etching chemicals.

Place and route - Printed circuit board

1 The design of a printed circuit board comes after the creation of a Circuit

diagram|schematic and generation of a netlist. The generated netlist is then read into a layout tool and

associated with part footprints from a library. Placing and routing can now

start.

Eurocard (printed circuit board)

1 'Eurocard' is a European standard format for Printed circuit board|PCB cards, which can be plugged together into a standardized

subrack. The subrack consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf. At the back of each card is one or more connectors, which plug into mating connectors on a backplane

which closes the rear of the subrack.
