China Wholesale Gps Tracker Circuit Board Pricelist - 8 Layer ENIG Impedance Control PCB – Huihe Detail:

Impedance is the combination of capacitance and inductance to hinder the circuit under high frequency signal. Impedance is an AC characteristic, which means it is frequency dependent. In the case of transmitting high-frequency signals, the controlled impedance helps to ensure that there is no significant attenuation of the signal during transmission. In essence, the controlled impedance means that the material characteristics of the substrate match the characteristics of the line/dielectric layer to ensure that the impedance value of the line signal is within the tolerance of the reference value.

Manufacturing Experience In Impedance Control Field

Impedance Modeling Software And Impedance Testing Hardware
HUIHE Circuits uses impedance modeling software and impedance testing hardware to meet your impedance control requirements. Polar’s “speedstack” and “CITS” toolsets combine high-quality field solutions and a comprehensive material library to ensure that your design can be a success once and for all.

Incoming Inspection And Supplier Management Process
In cooperation with major suppliers, the feeding process ensures consistent performance with the received raw materials (laminates, PP, copper foil).

Laser Direct Imaging Equipment
The LDI equipment avoids line width changes due to dry film expansion/contraction, and at the same time produces a clearer image on the copper surface, resulting in higher accuracy in line etching.

Etching Equipment Configuration
Once the impedance control PCB has been exposed to development it must be put into an etching machine for etching. The etcher must accurately set the parameters such as speed, temperature, pressure, nozzle direction and Angle to minimize side erosion. With many years of experience in the printed circuit board industry, Hui He Circuit has developed a mature etching process to ensure that customers require strict impedance tolerances.

Factors Affecting Impedance

Dielectric thickness: is the most important factor affecting PCB printed boards impedance value

Line width / line spacing: increase the line width to reduce the impedance, and reduce the line width to increase the impedance.

Copper thickness: decrease the line thickness, increase the impedance, increase the line thickness, and reduce the impedance

Dielectric constant:Increasing the dielectric constant can reduce the impedance, and decreasing the dielectric constant can increase the impedance. The dielectric constant is mainly controlled by the material

Our Advantage

1.More than 10 years of impedance manufacturing experience, strictly control wire width and medium thickness

2. Standardize the production process to ensure strict impedance tolerances

3. Complete product certification and factory system certification
