How to Avoid Crosstalk in HDI Substrate?

Miniaturization of the copper features in electronic circuits results from placing interconnections closely with a high packing density. As a result, crosstalk in HDI PCB substrate comes at play because of the increased coupling between the adjacent signal lines. HDI...

7 Tips and PCB Design Guidelines for EMI and EMC

Electromagnetic interference (EMI) is associated with every electronic device we use nowadays. If you turn on your radio set and TV simultaneously, you will experience the noisy disturbance from TV interfering with the radio signal and vice-versa. We can also...

Understanding Signal Integrity in PCBs

When a signal is transmitted, the received signal will always be distorted as a consequence of impedance and other effects. This is why designers work towards minimizing effects on the signal quality. Designers try to achieve signal integrity by limiting the extent to...

How To Limit Impedance Discontinuity and Signal Reflection in PCB Transmission Lines

What is a PCB Transmission Line?

A PCB transmission line is a type of interconnection used for moving signals from their transmitters to their receivers on a printed circuit board. A PCB transmission line is composed of two conductors: a signal trace and a return path which is usually a ground plane....
