required modernization, and the printed circuit through its continuous improvement circuite imprimate fabricare was one of the first aids that allowed this modernization. The smaller and smaller dimensions and the flexibility of the printed circuit board made in recent years have greatly helped fields such as medicine and
inscription of the printed circuit, called serigraphy or silkscreen for short, is done on the top layer of the PCB and has the role of a reference indicator for fabricare imprimate circuite the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent
it possible to measure the quality of copper tracks. The impedance is an alternating current (AC) characteristic that circuite imprimate fabricare 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)
