A popular rule is that no impedance matching between the trace and load is necessary if the critical length of a PCB trace (l crit) is 1/10th of the wavelength (λ). Yet is this rule of thumb correct?
You can see here that an inch of an average PCB trace can have between 0.1Ω and 15Ω of impedance depending on frequency or risetime of the signal. If we plug the impedance into Ohms law ...
For signal integrity in high-speed PCBs, use a PCB material with a low-loss tangent and a low dissipation factor. Materials ...
The work is published in the journal Lab on a Chip. They developed a printed circuit board (PCB) sensor integrating ...
For all practical purpose generally the PCB traces are routed as controlled impedances. For a typical single ended configuration the control impedance is 50 Ω, for differential 100 Ω and for USB ...
Although ABF has proven itself as a reliable material for substrate design, alternatives are on the horizon, both from established companies and startups. Whether one of these alternatives will win ...
In this section, we will see how the load impedance of the secondary can be reflected into the primary. Let us consider the transformer phasor circuit of Figure 9.28. We assume that the resistance of ...
Littelfuse, Inc. has introduced the 871 Series Ultra-High Amperage SMD Fuse, complementing the existing 881 Series. The new ...
Introduction ASUS is launching new AM5 socket motherboards, across the line, from bottom to top, based on the new AMD X870 ...
As the PCB design owner, you will oversee all electronic boards for BMS, MCU, chargers, and other key EV PCBA applications.
