Introduction:
The increasing complexity of electronic components and switches continually requires faster
signal flow rates, and thus higher transmission frequencies. Because of short pulse rise times
in electronic components, it has also become necessary for high frequency (HF) technology to
view conductor widths as an electronic component.
Depending on various parameters, HF signals are reflected on circuit board, meaning that the
impedance (dynamic resistance) varies with respect to the sending component. To prevent such
capacitive effects, all parameters must be exactly specified, and implemented with the highest level
of process control.
Critical for the impedances in high frequency circuit boards are principally the conductor trace
geometry,the layer buildup, and the dielectric constant (er) of the materials used.
