For traces with a certain width, three main factors will affect the impedance of PCB traces. First of all, the EMI (electromagnetic interference) of the near field of the PCB trace is proportional to the height of the trace from the reference plane. The lower the height, the smaller the radiation. Secondly, the crosstalk will change significantly with the height of the trace. If the height is reduced by half, the crosstalk will be reduced to nearly a quarter.
PCB (Printed Circuit Board) is an industry with a relatively low technical threshold. However, 5G communication has the characteristics of high frequency and high speed. Therefore, 5G PCB requires higher technology and the industry threshold is raised; at the same time, the output value is also pulled up.
We all know that there are many procedures for making HDI PCB from the planned feeding to the final step. One of the processes is called browning. Some people may ask what is the role of browning?
The advantages of heavy copper PCB make it the top priority for the development of high-power circuits. The heavy copper concentration can handle high power and high heat, which is why high-power circuits have been developed using this technology. Such circuits cannot be developed with low-copper concentration PCBs because they cannot withstand the huge thermal stresses caused by high currents and flowing currents.
When designing a circuit, factors such as thermal stress are very important, and engineers should eliminate thermal stress as much as possible. Over time, PCB manufacturing processes have continued to evolve, and various PCB technologies have been invented, such as aluminum PCBs, which can handle thermal stress. It is in the interests of heavy copper PCB designers to minimize the power budget while maintaining the circuit. Performance and environmentally friendly design with heat dissipation performance.
