When PCB trace widths change, impedance variations can cause signal reflections, which may be significant depending on the impedance change magnitude, signal rise time, and trace length; careful analysis and impedance matching can mitigate these effects.
Reflection resulting from variations in PCB trace width Read More »
In PCB layout, the change of line width can cause impedance change and reflection, which can affect the signal. Whether this effect needs to be considered depends on the size of the impedance change, the signal rise time, and the delay of the signal. The reflection can be reduced through impedance matching terminations and careful analysis of the parameters involved.
Our experience lies in creating multiple-layer, flexible circuits and rigid-flex PCBs HDI PCBs as well as Rogers PCBs.
We have a great track record in fast-turnaround prototyping of PCBs, and excel at managing challenging projects as a strength.
