Freedom CAD’s Expert PCB Design Tips, Part 2


Reading time ( words)

When you’re designing complex PCBs, knowledge truly is power. The more PCB design tips, tricks, and techniques you know, the better your cutting-edge designs will be. With that in mind, we’re bringing you a series of PCB design tips, courtesy of Freedom CAD Services.

Design Tip #2
Don’t make your high-current traces too long.

Today’s PCB designs require more diligence in order to meet the requirements of today’s high-speed microprocessors. At higher data rates, insertion loss becomes more critical. This results in signal length limitations due to insertion loss, very tight impedance matching, short stub lengths, and the use of higher performance PCB laminates.

Why We Simulate

04/29/2021 | Bill Hargin, Z-zero
When Bill Hargin was cutting his teeth in high-speed PCB design some 25 years ago, speeds were slow, layer counts were low, dielectric constants and loss tangents were high, design margins were wide, copper roughness didn’t matter, and glass-weave styles didn’t matter. Dielectrics were called “FR-4” and their properties didn’t matter much. A fast PCI bus operated at just 66 MHz. Times have certainly changed.

DFM 101: PCB Materials

04/30/2021 | Anaya Vardya, American Standard Circuits
One of the biggest challenges facing PCB designers is understanding the cost drivers in the PCB manufacturing process. This article is the first in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability.

Isola Releases IS550H Material

04/26/2021 | Nolan Johnson, I-Connect007
Nolan Johnson speaks with Michael Gay of Isola and Chris Hunrath of Insulectro about the release of their new halogen-free, high-thermal reliability material, which they hope fills the gap in the market between epoxies and polyimides.
