lines can be laid out in a planar form, such as imprimate circuite stripline or microstrip, with dimensions carefully controlled to ensure consistent impedance. In RF and fast switching circuits, the inductance and capacitance of the printed circuit board conductors become significant, usually unwanted, circuit elements; rather,
when the tracks carry signals at high frequencies, great care must be taken in designing the tracks to match the impedance of the upstream and downstream components. The imprimate circuite longer the route or the higher the frequency, the better adaptation is required. When producing the printed circuit with controlled impedance, the
users during assembly. It is used to mark component values, part numbers, test points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight discolorations due circuite imprimate to the high temperatures for gluing the components, so they are only PCB design
