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.
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.
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.
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these products, the designers must fluidly pass design changes back and forth between the ECAD and MCAD domains beyond outdated file exchanges.
High-speed digital PCBs are challenging enough to design, but what about mixed-signal boards? Many modern systems contain elements that operate with both digital and analog signaling, and these systems must be designed to ensure signal integrity in both domains. Altium Designer has the layout and signal integrity tools you need to ensure your mixed-signal PCB design does not experience interference and obeys important design standards.
Just as WiFi 6 and 6E are starting to hit the market and new chipsets become available, WiFi 7 is in the works under the 802.11be standard. While this technology still has not hit the market, I would expect more inquiries for experimental systems, evaluation modules, and surface-mountable modules to come up once the first chipsets become available. Now is the time to start thinking about these systems, especially if you’re developing evaluation products to support WiFi 7.
Rugged electronics need to take a punch mechanically, but there is more that goes into a rugged system than being able to survive a drop on the pavement. This is as much about enclosure design as it is about component selection and manufacturing choices. Mil-aero designers often use the term “harsh environment” to describe a number of scenarios where an electronic device’s reliability and lifetime will be put to the test. If you want to make your next product truly rugged, it helps to adopt some of their strategies in your PCB layout.
There are many quality checks used to ensure a design will be manufacturable at scale and with high quality, but a lot of this can happen in the background without the designer realizing. No matter what level of testing and inspection you need to perform, it’s important to determine the basic test requirements your design must satisfy and communicate these to your manufacturer. If it’s your first time transitioning from prototyping to high-volume production, read our list of PCB testing requirements so that you’ll know what to expect.
Getting started with design rules can sometimes be a difficult task, but it doesn’t have to be. Altium Designer has added a new design rules user interface along with a new way to define rules, while not compromising past methods. Now, rules and constraints have a design-centric view rather than a rules-centric view which allows for easier visualization and is less prone to error. Watch this video to learn how you can best utilize the improved Rules 2.0 design rule interface.
Embedded computers, vision devices, DAQ modules, and much more will all need some memory, whether it’s a Flash chip or a RAM module. Normally, something like a Flash memory chip or a small eMMC module would not be used for temporary storage as the device requires constant rewrites. Instead, if you happen to need a volatile memory solution, you would go for static (SRAM) or dynamic RAM (DRAM). If you need to decide which type of memory to use in your board, keep reading to see some of the basic design guidelines for SDRAM vs. DDR memory modules.
Using a PCB ground plane in a stackup is the first step towards ensuring power and signal integrity, as well as keeping EMI low. However, there are some bad myths about ground planes that seem to persist, and I’ve seen highly experienced designers make some simple mistakes when defining grounds in their PCB layouts. If you’re interested in preventing excess emissions and ensuring signal integrity in your layout, follow these simple guidelines for implementing a PCB ground plane in your next board.
As much as we’d like, the power we supply to electronics isn’t always stable. Real power sources contain noise, they might exhibit power instability, or they dropout unexpectedly. Thankfully, we have power regulators to help prevent some of these problems. For low power devices, we generally see two types of power regulators: a low dropout regulator (LDO) or a switching regulator. You can mix and match these at different points along your power bus, but there’s still the matter of choosing whether to use an LDO vs. a switching regulator in your designs.
