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.

Automated Trace Routing in Printed Circuit Board Design

When autorouters were first introduced, they were often difficult to use and delivered questionable results. Because of this, auto-routing was quickly labeled as “black-box magic,” and many designers hesitated to use it. Instead, they would choose to work long hours manually routing their designs. Today’s autorouters, however, are vastly improved from their predecessors and deserve a second chance. As you will see, they can exponentially increase your productivity as a PCB designer.

When Electronics Material Shortage in PCB Assembly Affects Your Production

PCB manufacturing requires raw materials for circuit board fabrication and electronic components for final assembly. Currently, the industry is experiencing shortages in both materials and components, and these shortages have a significant effect on the production of printed circuit boards. Here is a closer examination of the ongoing electronics material shortage in PCB assembly and what you can do to protect yourself.
