the printed circuit, called serigraphy or silkscreen for short, circuit imprimat asamblare is done on the top layer of the PCB and has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent
quality of copper tracks. The impedance is an alternating asamblare circuit imprimat current (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) and insulation thickness (h) of
components are soldered on the same side of the board. A board can use both methods for soldering components. Today PCBs with imprimat circuit asamblare components mounted only through holes are now less common. Surface mount is used for components like transistors, diodes, IC chips, resistors and capacitors. Through-hole
