When time-varying (AC) signals travel in the transmission lines of a board, state-changing electric and magnetic fields are present. These fields, when not controlled, are the source of noise and... [more]
With the advent of ICs with multiple power rails at very high currents, the design of the power delivery system in a modern product is often more difficult than routing the PCB to ensure good signal... [more]
Today’s SMT and PTH assembly processes are driven by component packaging technology and functional design requirements. These requirements are driving manufacturing/test toward “build right” and... [more]
Differential pairs have been used in PC boards for years to carry high-speed serial and high-speed parallel data, in a variety of bus formats. Many board designers and engineers believe the rules... [more]
