Understanding the characteristics of thick copper PCB

Thick copper PCBs are printed circuit boards with copper foil thickness greater than 1oz (i.e. 35μm), characterized by low resistance, high thermal conductivity, and high reliability.multilayer pcb fabrication Thick copper PCBs are commonly used for high power and high frequency applications. However, the issue of line compensation needs to be taken care of during circuit design.

Meaning of Line Compensation

Line compensation refers to a scientific and technological means of teaching in order to maintain the accurate information transmission of a signal when wiring on thick copper 1 oz vs 2 oz Copper PCBs. Line compensation can improve the stability and accuracy of the working signal by offsetting the transmission delay caused by the length of the traveling line alignment. The value of line compensation will directly affect the compensation effect of the analyzed signal and the performance of the circuit.

Reasonable range of values for line compensation

For circuit compensation on thick copper PCBs, it is necessary to determine the appropriate range of values according to the specific circumstances. In general, the following two methods are often used:.

1. Line compensation based on transmission delay

Transmission delay is the time required for a signal to propagate from the source to the target. By calculating the transmission delay of the signal under different line lengths, the range of line compensation is determined according to the design requirements.

2. Line compensation based on wave characteristics of data signals

Determine the line compensation value based on the frequency characteristics of the signal. High-frequency signals are affected by impedance pair matching during transmission, resulting in reflection and attenuation. Through appropriate linear compensation, the transmission characteristics of the signal can be improved and the overall performance of the system can be improved.

Optimize circuit design to improve performance

In addition to proper line compensation values, there are other ways to optimize the circuit design to further improve performance.

1. Use proper line width and spacing: Reasonable line width and spacing design can reduce the need for line compensation and improve signal transmission quality.

2. Optimize the ground wire for design: The layout and alignment of the ground wire has an important factor in signal interference and transmission technology effects. Reasonable ground design we can reduce electromagnetic interference and reflection problems.

3. Consider the electromagnetic compatibility: Consider electromagnetic compatibility in the design to reduce signal crosstalk and interference and improve overall performance.

Line compensation on thick copper PCBs is a key technical tool to improve signal transmission performance and circuit reliability. Through appropriate line compensation values and optimized design, the performance and reliability of the circuit can be further improved to meet the needs of different applications.
