How to Select Copper Foil for High-Frequency PCB Design

The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss for products with RF applications. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen in TDR measurements. In this article, we'll look at the balance between copper foil losses and other types of losses in a PCB, as well as some strategies that are commonly used to overcome roughness.

Is your via impedance calculator accurate?
Blog
Why Most Via Impedance Calculators Are Inaccurate

The problem with every via impedance calculator that I have seen is simple: they are incomplete or totally wrong. The “incomplete” part refers to a lack of context; these calculators can roughly reproduce a well-known estimate from a legend like Howard Johnson in his Digital Design textbooks. However, these calculators never provide insight into what they are actually calculating, or where the calculated via impedance is accurate. Keep reading to see why these calculators get it so wrong, as well as the context surrounding via impedance.

Buck Converter Simulation in Altium Designer

When designing high power circuits (usually very high voltage and/or current), you’ll need to create a regulator from scratch and place it in your PCB layout. It's also the case that you may want to model a real component using discretes in a simulation in order to qualify the system's expected operating regime. As part of buck converter design, you can easily run a buck converter simulation directly in Altium Designer’s schematic editor. Here’s how you can access these features in the newest version of Altium Designer.

Overview of the PCIe 6.0 Standard

Just as you get used to PCIe 5.0, they decide to release another standard! The newest iteration of PCIe is Gen6, or PCIe 6.0. PCIe 6.0 brings a doubling of channel bandwidth through introduction of PAM-4 as the signaling method in high-speed differential channels. This signaling method is a first for PCIe, and it’s an important enabler of the doubled data rate we see in the current standard. In this article, I’ll run over the important points in the standard and what PCB designers can expect when designing these channels.

SPI vs. I2C: How to Choose the Best Protocol for Your Memory Chips

One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).

Design Rule Checking in the PCB Design Workflow

Any time you design a PCB, and you want to turn it into a real product, you will have to make sure the design obeys the constraints within the standard PCB manufacturing process. This imposes multiple rules on any design, and ECAD software will enforce design rules as you create the board to ensure you obey these important constraints. Make sure you enforce the right design rules at the beginning of the PCB design workflow

Best Practices for High-Frequency PCB Material Selection

High frequency PCB design can seem esoteric, and I've heard many an engineer describe it as "black magic"! The subject is also a bit confusing, especially once someone asks which frequencies could be reasonably considered "high". Before you do anything inside the layout for a high-speed or RF PCB, you will need to pay attention to the materials being used in the board. If you're unsure which high frequency PCB materials you should use, then keep reading to learn more.

PCB Noise Reduction: Do You Need Isolation, Shielding, or Filters?

Of all the noise and operational challenges designers face in their PCBs, there is one overarching problem that is arguably most popular: electronic noise. It could originate as an SI/PI problem, it could possibly arise from some external source, or it could be good old-fashioned crosstalk! These tend to fall into three categories: adding shielding, doing something to create isolation, or placing filters. Let's look at all of these as they tend to be the default solution set when confronted with many noise problems.

Communicating PCB Layer Stackup Needs to Manufacturers

In the business of PCB design, communicating needs to manufacturers and vendors is a top priority. The context of our requests is sometimes lost either by not providing the correct information, not listing enough information, or not giving any information. Although the experienced PCB designer can take steps to specify everything they want to see in their PCB stackup, eventaully the manufacturer will handle that decision in an effort to balance available materials with processing capabilities and yield.

Risk Vs. Reward

Risk Vs. Reward

During the recent IPC APEX expo, there was a lot of discussion about SAP, or semi-additive PCB processes.  As with any new technology adoption there were people that are excited to jump right in and start designing with much finer feature sizes and work through the inevitable changes to the traditional thought process. Others are in a "let’s wait and see" mode and of course there are a few skeptics there as well, so keep reading to learn more.

Ebook: PDN Simulation and Analysis Guide

Most designers don’t realize they need to worry about power integrity until they have a power integrity problem. Other designers might build boards that can’t handle the demands of modern digital and high frequency components, and they may not realize the problems that lurk in their power delivery network (PDN). Although the basic concepts involved in designing for power integrity are well-known, myths about power integrity abound, and designers need tools to help them evaluate and qualify power integrity in a PDN.

Ferrite Beads and Transfer Impedance in a PDN Simulation

The use of ferrites in a PDN is one design recommendation that is fraught with unclear guidance and over-generalized recommendations. If you see an application note or a reference design that recommends placing a ferrite in a PDN, should you follow this in your specific design, or should you ignore this and focus on adding capacitance? 

PCB Design Outputs

Overview of PCB Design Output Files

Before your board can be put into production and prepared for assembly, you have to generate a set of files that assist your manufacturer. These are your PCB design output files, also known as manufacturing files, fabrication data, assembly files, and a host of other names. Before you send your design file off to a manufacturer in an email, make sure to get a list of their required fabrication and assembly files first. If you’re a new designer, take some time to read over the basic PCB manufacturing file extensions below.
