What PCB Copper Thickness Should You Use?
If you’re an electronics designer or you’re just beginning your career as an engineer, the PCB stackup is probably one of the last things you’ll think about. Simple items like PCB copper thickness and board thickness can get pushed to the back burner, but you’ll need to think about these two points for many applications as not every board will be fabricated on a standard 1.57 mm two-layer PCB

Should You Route Signals in Your PCB Power Plane?
I often get questions from designers asking about things like signal integrity and power integrity, and this most recent question forced me to think about some basic routing practices near planes and copper pour. "Is it okay to route signal traces on the same layer as power planes? I’ve seen some stackup guidelines that suggest this is fine, but no one provides solid advice." Once again, we have a great example of a long-standing design guideline without enough context.

The Anatomy of Your Schematic Netlist, Ports, and Net Names
Electronics schematics form the foundation of your design data, and the rest of your design documents will build off of your schematic. If you’ve ever worked through a design and made changes to the schematic, then you’re probably aware of the synchronization you need to maintain with the PCB layout. At the center of it all is an important set of data about your components: your schematic netlist. What’s important for designers is to know how the netlist defines connections between different components and schematics in a large project.

How to Compare PCB Manufacturing Services for Your Board
There are plenty of PCB manufacturing services you can find online, and they can all start to blend together. If you’re searching for a new service provider, it can be hard to compare all of them and find the best manufacturer that meets your needs. While experienced designers can spot bogus manufacturers from afar, there is always a temptation to go with the lowest priced, supposedly fastest overseas company you can find. However, there is a lot more that should go into choosing a PCB manufacturing service than just price.

Pi Filter Designs for Power Supplies
Pi Filters are a type of passive filter that gets its name from the arrangement of the three constituent components in the shape of the Greek letter Pi (π). Pi filters can be designed as either low pass or high pass filters, depending on the components used. The low-pass filter used for power supply filtering is formed from an inductor in series between the input and output with two capacitors, one across the input and the other across the output. Keep reading to learn more about their application in the PCB Design.

How to Design a Hybrid PCB Stackup
The first question that should come up when selecting materials and planning a stackup is: what materials are needed and how many layers should be used? Assuming you’ve determined you need a low-loss laminate and you’ve determined your required layer count, it’s time to consider whether you should use a hybrid stackup. There are a few broad situations where you could consider using a hybrid stackup with low-loss laminates in your PCB

Efficient Battery Power Supplies
Batteries offer a great power source for electrical devices that need to be mobile or located somewhere where connection to a mains electricity supply or other power source is impossible. The biggest problem with battery power is the expectation of users that the device will operate for significant periods with the need for recharging or replacing the batteries. This demand is placing the onus on the designer to improve efficiency and reduce power demand to meet this need.

What Target Impedance Should You Use in Your PDN?
A number of us on this blog and in other publications often bring up the concept of target impedance when discussing power integrity in high-speed designs. Some designs will be simple enough that you can take a “set it and forget it” approach to design a functional prototype. For more advanced designs, or if you’re fine-tuning a new board that has existing power integrity problems, target impedance is a real consideration that should be considered in your design.

An Overview of Dual Power Supply Design
Dual power supplies are circuits that generate two different output voltages from a single input source. The simplest method of generating dual output voltages is to use a transformer with two taps on the output winding. Bespoke transformers can have any voltage ratio depending on the number of windings in each part of the output side of the transformer.

Overlapping Planes in Your Mixed-Signal PCB Layout
With digital boards that are nominally running at DC, splitting up a power plane or using multiple power planes is a necessity for routing large currents at standard core/logic levels to digital components. Once you start mixing analog and digital sections into your power layers with multiple nets, it can be difficult to implement clean power in a design if you’re not careful with your layout.

ECAD MCAD Capabilities For Today’s Most Demanding Designs
Working between the Electronic and Mechanical design domains brings unique challenges. ECAD and MCAD tools have different design objectives and have evolved down different paths, and so have the way they store and manage their design and project data. To successfully design these products, the designers must fluidly pass design changes back and forth between the ECAD and MCAD domains beyond outdated file exchanges.

Modeling Copper Foil Roughness in Altium Designer's Impedance Profiler
With the new layer stack manager in Altium Designer®, you can now include copper foil roughness factors directly in your impedance calculator. This is quite easy to do in the layer stack manager, but it begs the question: what exactly is the copper roughness factor? Which value should be used for your interconnects?

High-Speed Signal Routing: The 5 Important Constraints
After you capture your schematic as an initial layout and create an initial component arrangement, it’s time to define your routing constraints. Doing this early will allow your DRC engine to spot rules violations before you finish your layout. Likewise, you’ll be able to modify the default rule set to meet your layout requirements. Here are the important routing constraints you’ll need to check before you start routing your board.

How to Create a PCB Manufacturing Cost Estimation
Some manufacturers have very convenient PCB manufacturing cost estimation calculators you can use, but the real costs depend on a number of factors. If you’re an entrepreneur and you’re producing your own boards, or you are managing manufacturing, testing, and delivery for a new project, it’s your job to help clients understand the primary cost drivers for new boards. Here’s how you can get an estimate of your fabrication costs, both for local and overseas manufacturers.

PCB Mountable Connectors: SMD vs. Through-hole
Selecting a connector is as much an art as it is a science. The artistic side is all about aesthetics and satisfying clearances, while the scientific side is all about signal integrity. For PCB mountable connectors, you’ll need to choose between surface-mounted or through-hole connectors, and you’ll need to consider how each type affects signal integrity in your application. Here’s what you need to think about beyond the standard connector specifications.

PCB Via Current-Carrying Capacity: How Hot is Too Hot?
Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool.

How to Maximize Copper in Your PCB Design: The Pros and Cons of Copper Pouring Versus Placing
There is a saying in copper pour PCB design, “Copper is free.” It means a PCB editor designer must think in reverse. A board starts off as solid copper, and the copper you don’t want is removed. It is faster to build, less consumptive, and less expensive to make a board that is mostly copper as compared to the same size board that is mostly bare. Picking the correct technique will make the difference between an effortless or frustrating experience.
