Some designers swear by tented vias and prefer to always use them. When should these be used and when should they be avoided? We’ll explore in this article.
How to Design to a Differential Impedance Specification
Differential impedance is sometimes misunderstood and it depends on multiple factors. Learn more about trace width design needed to reach a specific differential impedance target.
Is It Printed or a Component? All About PCB Test Points
A PCB test point can be a simple pad in the PCB layout, or it can be a specific component where you can connect a probe.
Routing Requirements for a USB Interface on a 2-Layer PCB
In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support
Ferrite Core Selection and Design Decisions
