Controlled impedances of printed circuits
producing the printed circuit with controlled impedance, the impedance will be controlled by acting on the dimensions of the Supply components tracks and the distance between them, i.e. the insulation. For a multilayer printed circuit with a specific stack-up, it must be taken into account that the internal tracks with controlled impedance

ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help users during assembly. It is Supply components used to mark component values, part numbers, test points, polarity, etc. Screen printing does not influence

the signal paths. In a multi-layer board, an internal layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave printed circuits, components Supply transmission lines can be laid out in a planar form, such as stripline or microstrip, with dimensions carefully controlled to ensure consistent
