A Beginners Guide to Impedance Control in PCBs

When a digital signal is transmitted from one point to another, it causes a change in the state of the signal line. This change can be understood as an electromagnetic wave moving through the circuit. Reflection occurs when this wave encounters a boundary between different mediums. At this boundary, some of the wave's energy continues as a signal, while the rest is reflected. This process repeats until the energy is either absorbed by the circuit or dissipated into the environment. For electrical engi......

Understanding the Importance of DFM Analysis in PCB Design
