Polar Instruments – a specialist in tools for pcb design, fabrication and test - has announced a free webinar on pcb layer stackup design using differential pairs. Presented by signal integrity guru, ...

Part 1 of this series described how digital signals propagate through PC boards [Refs. 1, 2, 5, 6]. In part 2, we look at specific board designs to achieve low EMI. The biggest issue I see in my ...

In recent months, the ability to hide components inside a circuit board has become an item of interest. We could trace this to the burgeoning badgelife movement, where engineers create beautiful works ...

Eventually, almost every EE must design a PCB, which isn’t something that’s taught in school. Yet engineers, technicians, and even novice PCB designers can create high-quality PCBs for any and every ...

Once a printed circuit board (PCB) has been assembled it’s rather hard to look inside of it, which can be problematic when you have e.g. a multilayer PCB of an (old) system that you really would like ...

A frequently asked question during Printed Circuit Board (PCB) layout review meetings is, “Are 50-ohm traces being used for the digital signals in this PCB layout?” Often the answer to this question ...

What is software defined radio (SDR) and how does it benefit modern communications and RF applications? RF/microwave PCB design for Radar and SDRs. Challenges of SDR PCB design and ways to overcome ...
