- Flexible printed circuits was born around 1960 by using polyimide film developed by DuPont in the USA. As the name suggests, FPCs are printed circuit boards in the form of film that have outstanding flexibility and bendability. At first, they were used in aerospace indus-try and other applications that required high reliability.

Quad Flat No-leads package Flat no-leads packages such as quad-flat no-leads and dual-flat no-leads physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe and SON, is a surface-mount technology, one of several package technologies that connect ICs to the surfaces of PCBs without through-holes. Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide el

Printed circuit board Printed circuit board with components attached. A printed circuit board (PCB) is a plastic board made for connecting electronic components together. These are used in almost all computers and electronics today. The card is made of a material that does not conduct electricity, like fiberglass or plastic.

- An electrical circuit is any closed loop that allows a flow of electrons in a current to deliver energy or perform work and then return to their source.Material along which electrical current flows freely are called conductors. (e.g. copper-wire) The electrons emit and return to an energy supply.he minimum components that are needed for an electrical circuit to do useful work are:- A battery(or an electricity source), conducting wire from which electricity can flow … , and a resistror(which is anything like lamp, bulb,ceiling fan etc.) !! 5 people found this useful.

photolithography Part of the Microprocessors glossary: Photolithography is the standard method of printed circuit board (PCB) and microprocessor fabrication. The process uses light to make the conductive paths of a PCB layer and the paths and electronic components in the silicon wafer of microprocessors.The photolithography process involves light exposure through a mask to project the image of a circuit, much like a negative image in standard photography.This process hardens a photo-resistive layer on the PCB or wafer. The hardened areas stay behind in the form of circuit paths of PCBs and CPU s.hotolithography is the standard method of printed circuit board (PCB) and microprocessor fabrication.

Printed circuit board Although more accurate, the term printed wiring board has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies.

Printed circuit board A legend is often printed on one or both sides of the PCB. It contains the component designators, switch settings, test points and other indications helpful in assembling, testing and servicing the circuit board.rinted 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.

Digital printing Digital printing. Digital printing refers to methods of printing from a digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers.

LC circuit LC circuit (left) consisting of ferrite coil and capacitor used as a tuned circuit in the receiver for a radio clock. An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.

Printed circuit board Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards.

- From Wikipedia, the free encyclopedia. In electronics design, tape-out or tapeout, also known as pattern generation or PG, is the final result of the design process for integrated circuits or printed circuit boards before they are sent for manufacture. The tape-out is specifically the point at which the artwork for the photomask of the circuit is sent to the fabrication facility.
