The 8-layer gold finger PCB is actually coated with a layer of gold on the copper clad laminate by a special process, because the gold has strong oxidation resistance and strong conductivity.
Ro4003c high frequency PCB--High frequency of electronic equipment is the development trend, especially in the development of wireless network and satellite communication, information products tend to be high-speed and high-frequency, and communication products are moving towards the standardization of voice, video and data of wireless transmission with large capacity and high speed. Therefore, high-frequency substrate is required for the new generation of products.
When the 40-layer M6G high speed PCB is close to the parallel high-speed differential signal line pair, in the case of impedance matching, the coupling of the two lines will bring many advantages. However, it is believed that this will increase the attenuation of the signal and affect the transmission distance.
Megtron6 high speed PCB needs not only high-speed components, but also genius and careful design. The importance of device simulation is the same as that of digital. In high speed system, noise is a basic consideration. High frequency will produce radiation and then interference.
The process of Meg6 high speed PCB design is usually: Layout - pre wiring simulation - change layout - post wiring simulation, and the wiring is not started until the simulation results meet the requirements.
Definition of Meg7 High speed PCB: it is generally believed that if the frequency of the digital logic circuit reaches 45,50MHz and the circuit working at this frequency accounts for a certain proportion of the whole system (such as 1amp 3), it will become a high speed circuit.
