How to Assign Names to Polygons

For some polygons, it is not always reasonable to use an automatically generated name so a custom name is needed. With a proper polygon name, you can quickly find the desired polygon in a list and correctly set the pour priority in relation to other polygons. By using unique names, you can create design rules that apply only to specified polygons.

Time Based Matched Lengths

High-speed digital circuits depend on signals and data arriving on time. If traces are improperly tuned, flight times vary and data errors can be abundant. Altium Designer 20 introduces the calculation of the propagation time on traces and provides synchronized flight time for high-speed digital signals.

Embedded thumbnail for Return Path Design Rule
New in Altium Designer 20 Feb 24, 2020
Return Path Design Rule

High-speed signals create electromagnetic fields that can cause cross-talk or data errors unless proper return paths are provided. Proper return paths allow noise currents to return to ground through a very low impedance, eliminating any problems. The new Return Path design rule monitors return paths and checks for a continuous signal return path on the designated reference layer above or below the signals targeted by the rule.

Driving Haptic Vibration and Feedback in Wearables

Augmented reality, virtual surgery, limb replacements, medical devices, and other new technologies need to incorporate haptic vibration motors and feedback to give the wearer a full sense of how they are interacting with their environment. Unless these cutting-edge applications include haptic vibration and feedback, users are forced to rely on their other four senses to understand the real or virtual environment.

Back Drilling Example in Altium Designer: One of the Easiest Ways to Improve Signal Integrity

Over the last 20 years, electronic devices have become increasingly sophisticated. Less than two decades ago, just having a mobile phone to make calls was rare; today, our phones power our lives. To meet the growing demand for smartphone technology, technology has become faster, more functional, and intuitive. Improvements to the component base have streamlined processes while reducing manufacturing costs.

Is it Simultaneous Switching Noise or Crosstalk?

Going deeper into crosstalk, there is always the issue of verifying EMI/EMC compliance through test and measurement. With the multitude of signal integrity problems that can arise in real PCBs, how can the astute designer distinguish them all? Some problems are clearer than others, with specific signal integrity measurements being developed for testing and measuring particular aspects of signal behavior. The fact is, multiple signal integrity problems could be present on a single interconnect simultaneously.

Sharing PCB Data with Manufacturers in the Cloud

Once you’ve finished your new project and you’re ready to push it to your manufacturer, you’ll normally be stuck in an endless email chain with an engineer, or you’ll have to share cloud links with each other. The cloud sharing and design release tools in Altium Designer and Altium Concord Pro are a huge help in this area. In this post, I’m going to take an existing project I’ve worked with in a number of recent blogs, create some fabrication and assembly documentation, and finally push this data to a manufacturer using Altium Concord Pro.

The Great PCB Layout "Rules of Thumb" Debate Rages On

To this day, I still see many PCB layout “rules of thumb” that first became common nearly 20 years ago. Do these rules still universally apply? The answer is a firm “maybe.” The discussion around PCB layout rules of thumb is not that these rules are correct or incorrect. The problem is that the discussion around these rules often lacks context, leading to the always/never type of discussion seen in some popular forums. My goal in this article is to communicate the context behind the common PCB design rules.

How to Design Your PCB Test Coupon and What You Can Test

As the operating speed of components has increased, controlled impedance is becoming more common in digital, analog, and mixed-signal systems. If the controlled impedance value for an interconnect is incorrect, it can be very difficult to identify this problem during an in-circuit test. However, testing is normally performed on a PCB test coupon, which is manufactured on the same panel as the PCB. If you want to get through board spins quickly and aid future designs, you might consider designing a test coupon and keeping it handy for future designs.

What is a Schematic Netlist for Your PCB?

If you’ve created your next great schematic, there is a lot going on behind the scenes in your design software. A schematic netlist is one of the central pieces of information that will be used in multiple features in your design software to create a real PCB. Your schematic netlist provides both electrical connectivity information, and reflects the functional structure of your design data in a single set of data.

How to Select an Inductor for a Buck Converter

An SMPS is one of those quiet (yet electrically noisy) devices that makes your favorite electronics run smoothly. Among the numerous DC-DC converter topologies, a buck converter finds plenty of uses for stepping down the input voltage to a lower level while providing high efficiency power conversion. A common question around component selection for these power converters is how to select an inductor for a buck converter. The goal in working with an inductor and other components in a buck converter is to limit power loss to heat and while minimizing current ripple.

Bluetooth 5.1 SoC vs. Module: Which is Best for Your Design?

The list of features available in Bluetooth just got a little longer since the release of Bluetooth 5.1. If you want to incorporate a Bluetooth 5.1 SoC into your new product, you have two primary options for bringing this component into your board. The first is as an SoC that mounts to your board just like any other component. The other option is to bring a module into your new board—directly onto the surface layer. Here’s what you need to know about a Bluetooth 5.1 SoC or module in your next IoT product.

USB Power Delivery for Your Next Project

Since its introduction in the late 90s, the USB standard has never ceased to grow in popularity. There has been a growing trend toward USB being a power delivery interface with data, rather than a data interface that can supply power, as the 1.0 specification originally intended. To supply the increasing thirst for power over USB, the USB 3.0 Spec with Type-C began implementing the Power Delivery standard, which you should consider using for your next electronics project.
