The printed circuit, PCB -printed circuit board- is an important electronic component used in any electronic equipment.
The printed circuit board can be planted or assembled manually or automatically, automatic soldering and automatic inspection of electronic components guarantee the quality of electronic equipment, improve work productivity and reduce costs.
Our printed circuit boards are used for a variety of purposes, safety and surveillance, power supply, telecommunications, automotive electronics, medical appliances and instruments, national defense and industrial equipment, etc.
the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four and especially more than six layers of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are assembled by Manufacture circuit printed of board their legs passing through the board and glued to
it possible to measure the quality of copper tracks. The impedance is an alternating current circuit printed board of Manufacture (AC) characteristic that increases with frequency and becomes critical for printed circuits operating at frequencies above 200 or 300 Mhz. Impedance calculator software is a good starting point to determine the track width (w)
PCB and has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's Manufacture circuit of printed board PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render useful
