Crosstalk or Coupling
The words crosstalk and coupling are used to describe the injection of electromagnetic energy from one transmission line to another running nearby. In printed circuit boards crosstalk is usually two traces running side by side in the same layer or one over the top of the other in adjacent layers. This coupled energy appears as noise on the victim trace and can cause malfunctions if the amplitude is too large. Learn how this noise is transferred

Transmission Line Termination Techniques in High-Speed Design
A transmission line is a pair of conductors used to deliver energy in the form of an electromagnetic field. Most of us are familiar with the wires that lead to our houses delivering the power needed to operate our lights and appliances. In the context of PCB design, it is a signal in a signal layer on top of a plane or between two planes. TRANSMISSION LINE TERMINATION TECHNIQUES FOR PCB DESIGN The purpose of this section is to explain what

Clone and Modify an Arduino Mega PCB Schematic in Altium Designer
There are many different Arduino boards available for development and prototyping, and you might consider designing your own Arduino PCB schematic. If you want to modify an Arduino Mega schematic, you need design software that lets you easily build around an Arduino board and quickly add functionality. Your design software should make it easy to use any Arduino mega pinout board, like the Arduino Uno PCB schematic, Mega, Zero, or another model

The Best PCB Design Software Downloads
There are many PCB design software packages available for download or purchase. Newer designers and startups who are just starting out will likely build up their skills from a free software program just to get to a proof of concept and initial design of a prototype. Once a design has been proven and it is time to design for a real product, a new designer or startup startup company will need to make the switch over to a paid software package. To

The Best PCB Layout & Design Software for Your Needs
When designing circuit boards, there are some functions that your PCB (printed circuit board) design tools must excel at without exception. These include the basic functions of schematic design, schematic capture, placing parts, and routing traces. There are other important functions you won’t find in free PCB design software. These include bill of materials compilation, generation of Gerbers and other deliverables, and data management functions

Design Your PCB Stackup with Altium Designer
Your PCB stackup is the foundation for your circuit board and will influence signal behavior. Your signals use internal plane layers as a potential reference, and your signal routing can be made easier with the right layer stack. In addition to determining the right arrangement of board layers, different board materials are placed in your PCB layer stack to satisfy calculations for power, impedance, and signal integrity. Modern designs will use

The Altium PCB Auto Router: The Best PCB Automated Routing Tool
Routing traces on your printed circuit board is that critical step during layout that creates the connectivity and functionality your board needs. It can also be time-consuming if your design autoroute software doesn’t contain the right routing tools. Your PCB design software should include high-precision routing tools that are designed to automate many portions of the routing process. Advanced PCBs require the best PCB auto-router, and your

The PCB Design Process Methodology and Application
Your next great idea probably started on a piece of notebook paper. How do you go about taking your great idea and turning it into a real design, and eventually into a finished product? There are a number of ways to approach your new design. Any new circuit board can be very complicated, but the right PCB design process methodology helps you get through the design process quickly. PCB designers follow a general PCB design process methodology, and

Easily Create Your PCB Solder Mask Layer in Altium Designer
You’ve just finished the electrical layout of your board and now you are working through the final steps to prepare for PCB manufacturing and assembly. What steps do you need to take to get your board ready for production? Aside from generating deliverables like Gerber files, a bill of materials, drill files, silkscreen, and PCB assembly instructions, you’ll need to define the solder mask (sometimes called solder stop mask or solder resist) on

Use PCB Routing Tools With an Integrated Trace Length Matching Calculator
If you’re a mechanical or electrical designer, you need CAD tools that provide accurate trace length and geometry calculations. Once you start working with high-speed or high-frequency circuits, propagation delay and skew become critical points to consider as you need to make sure your signals are properly timed throughout your nets. Altium Designer is the only PCB design package that includes an ultra-accurate trace length calculator for PCB

Free Schematic Drawing Software and PCB Layout Tools in Altium Designer
Every circuit board starts with circuit diagrams and schematic sheets. Your schematic capture software takes your component and footprint data and creates an initial layout, which you then route to create a complete circuit board. If you’re just getting started with PCB design, you need a schematic diagram maker that helps you quickly move component data into a new layout. You shouldn’t need to use multiple programs to move from schematic drawing

Flex and Rigid-Flex PCB Design Guidelines and Assembly in Altium Designer
Many electronic devices don’t live on a single printed circuit board. Flex and rigid-flex PCBs are used to link multiple rigid PCBs together into a single unit. This allows printed circuit designers to customize their board to odd enclosures, design motion into new devices, and provides unique form factors that are not possible with rigid boards. Many other common devices are shrinking, and the PCBs that power them are following suit. If you’re

How Are Circuit Boards Made With Altium Designer
Your printed circuit board (PCB) design might be designed to work correctly, but you also need to make sure it can actually be manufactured. Although a PCB manufacturer will fabricate and assemble your circuit boards for you, making sure your designs are manufacturable is about encoding DFM specifications in your design rules. With the rule-driven design features of Altium Designer, you can encode DFM specs into your PCB’s design rules; this
