As the world of technology has evolved, so has the need to pack more capabilities into smaller packages. PCBs designed using high-density interconnect techniques tend to be smaller as more components are packed in a smaller space. An HDI PCB uses blind, buried, and micro vias, vias in pads, and very thin traces to pack more components into a smaller area. We’ll show you the design basics for HDI and how Altium Designer® can help you create a powerful HDI PCB.

Test points in your electronic assembly will give you a location to access components and take important measurements to verify functionality. If you’ve never used a test point or you’re not sure if you need test points, keep reading to see what options you have for test point usage in your PCB layout.

The concept and implementation of differential impedance are both sometimes misunderstood. In addition, the design of a channel to reach a specific differential impedance is often done in a haphazard way. The very concept of differential impedance is something of a mathematical construct that doesn’t fully capture the behavior of each signal in a differential trace. Keep reading to see a bit more depth on how to design to a differential impedance spec and exactly what it means for your design.

Quite often, a standard assembly drawing is not enough to ensure the quality of a PCB assembly, especially when designing high-density boards. It would also be helpful to include additional detailing for simpler devices. The use of a Draftsman document brings an elegant, yet powerful solution to make these tasks easier.

An effective product lifecycle management (PLM) solution will integrate the tools and processes employed to design, develop and manufacture a new device. This solution goes beyond engineering activities to include the project management, process control, and financial management of the end-to-end business processes. PLM solutions create this collaborative environment where product development can flourish, bringing additional benefits in efficiencies and transparent communications, breaking silos, and speeding up the development process.

With ever increasing speeds in high-speed data systems comes a couple of PCB layout challenges. High-speed busses like DDR, VME, PCIe just to mention a few can all reach data transfer speeds that require strict timing with very tight tolerances, thereby leaving very little slack in the PCB layout. Watch this on-demand webinar to learn why it's imperative to match track lengths in high-speed data systems and differential signals. You’ll see how to properly define PCB length matching and time delay constraints, and how to effectively route high-speed signals in Altium Designer®.

In this article, we want to get closer to a realistic description of tight coupling vs. loose coupling in terms of differential pair spacing, as well as how the differential pair spacing affects things like impedance, differential-mode noise, reception of common-mode noise, and termination. As we’ll see, the focus on tight coupling has its merits, but it’s often cited as necessary for the wrong reasons.

You’ve possibly gone through plenty of engineering design reviews, both on the front-end of a project and the back-end before manufacturing. Engineering design reviews are performed to accomplish multiple objectives, and with many engineering teams taking a systems-based approach to design and production, electronics design teams will need to review much more than just a PCB layout and BOM. Today’s challenges with sourcing, manufacturability, reliability, and mechanical constraints are all areas that must be confronted in real designs

One of the most common points of failure of a device occurs even before you start to layout your circuit board. Mistakes in your schematic design can easily make their way all the way into prototypes or production without a second thought once layout starts. In this article, I’m not going to extol the virtues of a good schematic design. Instead, this article is a simple no frills checklist.

One common question from designers is current-carrying capacity of conductors in a PCB. 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. Let’s dig into the current state of thermal demands on vias in PCBs and how they compare to internal and external PCB traces.

An optoisolator is a cool electronic device that can be used to pass information between a diode without passing an electrical current. There are many great applications for these, but do you know which one is right for you?

The Properties panel provides access to the properties of documents and objects. The contents of the panel change depending on the active document or the selected object. This blog will quickly go over some of need to know options around the properties panel in the schematic document.

Even with all the good guidelines out there for high speed design, there are particular aspects of stackup construction and their relation to building boards that get overlooked. This blog is goes beyond just the typical SI/PI guidelines and looks at these problems from more of an engineering perspective.

Stitching vias are something you often see spread around the surface layer of a PCB, but what are they? and should you be using them? In this guide, we'll go over some of the standard uses of stitching vias and when they should be used in a PCB.

In comparison to the build-up of a PCB, the stackup is more concerned with the electrical type of each layer, that is are we working with signals, power, or ground. Continue reading to learn how you can optimize your layer stack.

Altium’s VP of marketing Lawrence Romine discusses the multi-board and harness design capabilities coming in Altium Designer 23.

Controlled ESR capacitors are important for power integrity in your design as they can help smooth out the PDN impedance spectrum in your high speed PCB.

Whenever we say something to the effect of “components can’t work without a correctly designed PCB,” we only have to look at component packaging for evidence. It is true that component packages come with parasitics that affect signal integrity, but there is one area that we don’t often look at in terms of component packaging: power integrity.

In this article, we’ll look at all that is required to start creating your own custom microcontroller-based hardware designs. You’ll see that there actually isn’t too much to this, as microcontroller manufacturers over the years have tried to make the learning curve less steep and their devices more, and more accessible. This is both from an electrical point of view but also – equally importantly – from a programming point of view.

If you’ve taken time to learn about PCB material options and layer constructions, you have probably seen the wide range of materials that are available on the market. Materials companies produce laminates with varying Dk values, Tg values, weave styles, CTI values, and mechanical properties to target various applications in the electronics industry.

If you’re waiting for truly connected cars on a grand scale, there is still a massive amount of work to be done, both on the hardware and software sides. Connected cars can only become a widespread reality once the automotive industry and telecom carriers can decide which protocol will work best for vehicle-to-everything (V2X) communication. PCB designers will then need to step in to create these systems and fit them into a vehicular environment.

This one area of PCB design can be contentious among some designers as it is related to copper pour, which it is often stated is not needed in most designs. Regardless of your feelings about copper pour, stitching vias have important uses in PCBs at low frequencies and at high frequencies.

The IPC-2221 standard includes many requirements for printed circuit board design and manufacturability, and there are several online calculators that have been developed based on this standard.

When you’re ready to manufacture a new device at production volume, there are many aspects of the product that must come together. The enclosure, cabling and connectors, embedded software/firmware, and of course the PCBA all have to be considered in totality. There is a quick way to get your product into a usable enclosure, complete with input power and cabling, and with a form factor that fits your PCBA. This overused route to a new product is a box build assembly.

Printed circuit board fabricators have become skilled at manufacturing these technologies and also at understanding the reliability and producibility challenges associated with high-density-interconnect technology. Let’s look at where the PCB industry is at today.

What can the industry do to support PCB designers as they continue taking a more active role in product development? Here at Altium, there has been a progressive shift towards looking at the system level and creating tools that get designers more involved throughout the product development process. As the saying goes, over the wall engineering is over… today’s most successful products are built in a collaborative process.
