Substrate routing
WebIt is therefore necessary to keep the impedance value as constant as possible, which in turn depends on the width of the trace, the thickness of the trace, the dielectric constant of the material used for the substrate (Ɛr), the thickness of the substrate and the layout of the traces on the PCB. Common impedance values are between 25 and 120 Ω. Web28 Sep 2012 · The routing density in a multichip substrate can be about one hundred (100) times less dense than a routing density in a chip level routing process. Problems associated with using the lower routing densities can include larger areas of the substrate dedicated to I/O and decreased system and power performance.
