Understanding Signal Integrity in PCB Rules and Techniques

Electronic devices and systems rely on the clear and uninterrupted high-speed transmission of data within their circuitry. However, the signal transmission integrity can be degraded by both internal and external sources of electronic interference. It is vital to lay out the PCB to mitigate such degrading effects and ensuring the signal’s clear delivery. Here are some rules and techniques for signal integrity in PCB design that can help.


Crystal Oscillator PCB Layout Guidelines

The resonance of a vibrating quartz crystal is often used in electronics to determine the oscillation frequency for timing signals in a circuit board. While there are different ways to create this timing, quartz crystals are well known for their effectiveness and stability. Like many other high-speed circuit board design aspects, the oscillator circuitry needs to be laid out with care to avoid signal integrity issues. Here are some crystal oscillator PCB layout guidelines that can help.

PCB Design Rules for High-Frequency Printed Circuit Boards

Personal computing devices, IoT, and many other embedded systems now require a diverse amount of electronics built onto one circuit board. These systems usually combine digital and analog circuitry running at high frequencies, creating many problems for circuit board designers if they aren’t prepared. Controlling signal and power integrity in a design is essential to avoid EMI problems that can ruin the device’s performance and cause it to fail its validation tests. Here are some PCB design rules for high-frequency layouts that can help.

Updates on Electronic Component Supply Shortage: What To Expect

Many initially hoped that this shortage would pass quickly, but several issues have converged, making the situation worse. The global pandemic introduced new problems into the supply chain and exacerbated the pre-existing. The important thing now is to focus on repairing the damage to move forward. Here are some updates on the electronic component supply shortage and what to expect next.
