| What's the way to confirm pcb impedance measuring point? |
|
|
Actual pcb impedance often can not be directly measured, Therefore, most of the test sample are design standards to do simulation in board edge.
Process control and impedance-related parameters should be controlled.
such as: material type, thickness uniformity, line width, copper thickness etc should be considered.
There is no simple answer to the optimum value, each pcb manufacturers must be based on all used material itself and parameters to make adjustments, experts can not answer, unless he can direct involvement throughout the whole manufacturing process and fully grasp all the factors.
