Properties of the printed circuit board
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, they can be used as part of the circuit design, as in distributed element filters, antennas, and fuses, avoiding the PCB Layer 2 need for
Printed circuit board construction
more layers of copper sheets laminated on and/or between layers of conductive substrate sheets. A printed circuit board can have several layers of copper which are almost always arranged in pairs. The number of layers and the designed interconnection between them (vias, PTHs) gives a general
Controlled impedances of printed circuits
software is a good starting point to determine the track width (w) and insulation thickness (h) Layer 2 PCB of a given impedance. In terms of signal traffic in printed circuits, when the tracks carry signals at high frequencies, great care must be taken in designing the tracks to match the impedance
