mixed-signal PCB Prototype Fabrication

A basic tutorial on proper printed circuit board (PCB) layout for grounding of mixed-signal PCB designs with ICs that have separate analog and digital ground pins.

HemeixinPCB has created the option of checking the required impedance on the customer's circuit board, so as to modify the circuit board, or the tracks and the layer structure if necessary. The impedance is largely determined by the track geometry, the structure of the layers and the dielectric constant (Er) of the materials used.

After making the circuit board, the impedances are checked and recorded. The results of the measurements are available on request at any time.
