The factors of impedance control include the calculation for accurate trace width and spacing between traces, as well as the dielectric thickness before building the PCB. The impedance calculator we are using is professional and efficient, it provides us very detailed values in trace width, spacing, and stack up, meeting your board’s thickness and impedance requirements.

During PCB fabrication, we can well control the impedance value with our advanced technology including image transfer, copper etching and PCB lamination. Impedance test reports will be made after fabrication and we guarantee every PCB that we make meets your impedance requirements and every order comes with an impedance report to go along with the PCB’s.
