all fields of activity has led to a revolution in the types and models of printed circuits. Technology has penetrated more and more areas of our lives and required modernization, and the printed circuit through imprimate circuite its continuous improvement was one of the first aids that allowed this modernization.
components using pads for bonding the component terminals and electrically connect them using traces of one or more layers of copper sheets laminated on and/or between layers of conductive circuite imprimate substrate sheets. A printed circuit board can have several layers of copper which are almost always
must be taken in designing the tracks to match the impedance of the circuite imprimate upstream and downstream components. The longer the route or the higher the frequency, the better adaptation is required. When producing the printed circuit with controlled impedance, the impedance will be controlled by
