Stripline Impedance

2018-06-04 17:24:28 by

Stripline Impedance     A stripline trace is defined as a conductive trace in a dielectric material between two reference planes. The dielectric constant of the dielectric material is homogenous meaning it has the same dielectric constant throughout. This is unlike a microstrip trace that has an effective dielectric constant that is a mix ofContinue Reading..

Microstrip Impedance

2018-06-04 17:22:08 by

Microstrip Impedance     A microstrip trace is defined as a conductive trace on a dielectric material over a reference plane. The top and sides of the trace are exposed to air called a surface microstrip trace. In actual manufacturing the top is usually covered with solder mask and is called a coated microstrip trace.Continue Reading..
