Any trace on the Temperature Sensor PCB reverse engineering will cause a time delay to the signal when passing through a high-frequency signal. The main function of the serpentine trace is to compensate for the lesser delays in the “same group of related” signal lines. Usually there is no or less logic than other signals; the most typical is the clock line, usually it does not need to go through any other logic processing, so its delay will be less than other related signals.
The equal length of the Temperature Sensor PCB board is to keep the delay difference of each signal within a range, and to ensure the validity of the data read by the system in the same period (when the delay difference exceeds one clock cycle, the next cycle will be misread. Data), generally requires that the delay difference does not exceed 1/4 clock cycle, the line delay difference per unit length is also fixed, the delay is related to the line width, the line length, the copper thickness, and the plate layer structure, but the line too long will increase the distributed capacitance which can be testified by PCB CLONING CIRCUITRY DESIGN SKILL.
And distributed inductance, so the signal quality and the clock IC pin is generally connected to the RC termination, but the serpentine trace does not act as an inductor. Conversely, the inductor will cause the higher harmonic phase shift in the rising element of the signal. The signal quality is deteriorating, so the minimum spacing of the serpentine line is required to be twice the line width. The smaller the rise time of the signal, the more susceptible it is to the distributed capacitance and distributed inductance whih can be discovered in the process of Temperature Sensor PCB Reverse Engineering.
Because the application has different functions, if the serpentine trace appears in the computer board, it mainly acts as a filter inductor to improve the anti-interference ability of the circuit. The serpentine trace in the computer motherboard is mainly used in Some clock signals, such as PCIClk, AGPClk, have two functions:
1. Impedance matching
2. Filtering inductance.
For some important signals, such as HUBLink in the INTEL HUB architecture, a total of 13 runs 233MHz, the requirements must be strictly equal length to eliminate the hidden danger caused by time lag, winding is the only solution.
In general, the line spacing of serpentine traces is >= 2 times the line width. The snake line on the Temperature Sensor PCB board is designed to accommodate the line length requirements of the PCI 33MHz Clock which are also commonly seen when execute with HIGH SPEED PRINTED CIRCUIT BOARD GERBER FILE CLONING. In the general ordinary PCB board, it is a LC filter with distributed parameters, and can also be used as the inductance coil of the radio antenna. The short and narrow serpentine trace can be used as a fuse.
