Impedance Control PCB

 Impedance Control PCB , pcb circuit strictly control the trace width, thickness and dielectric thickness, pcb circuit tolerance of impedance trace ≤±5% is better for impedance matching, pcb circuit apply to High-frequency/high-speed devices and 5G communication equipment. HUIHE CIRCUITS Impedance Control PCB has passed ISO9001 / ISO13485 /IATF16949 / UL /RoHS / REACH certification.

 

Classification Of PCB Impedance

Characteristic Impedance: (Characteristic Impedance) When two conductors are insulated from the earth, the impedance between each other.

Differential Impedance: (Differential Impedance) the measured impedance between two conductors.

Factors Affecting Impedance In PCB

A: The dielectric constant (TMr) is determined by the raw material. (Plate, prepreg)

B: Circuit thickness (T): Determined by raw materials and process capability.

C: Line width (w): Determined by the customer's design manuscript and process capability.

D: Media thickness (H): Determined by the customer's design manuscript and process capability and raw materials.
