Differential Pair Routing for SI and EMI Control

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]

PC Board Grounding to Control Noise, EMI and Signal Integrity

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]

How to Fight Magnetic Noise Gremlins

Have you ever had a noise-sensitive circuit and tried to find the noise source? Even after you completely encased sensitive portions in all sorts of shielding, you still had noise? It’s very... [more]

Best DFM Practices for Board Engineers

There is more to board design than placing parts and connecting the signals electrically. Those who design the board can make a huge impact on the ease of fabrication and assembly just by adhering... [more]
