The idea of a purely capacitive load is something of a fallacy. Yes, capacitors exist, but all capacitors are non-ideal, and it is this deviation from a theoretical capacitance that determines how to impedance match a load that exhibits capacitive behavior. Let’s take a look at this important aspect of interconnect design and see what it really means to terminate a capacitive load.
There are all sorts of version control systems out there that people have been using with their PCB design software. As discussed in Why Use a Version Control System, we looked at different options ranging for local hard drive storage to sophisticated online revisioning systems. In this article we will be reviewing the differences between a standard VCS and Altium 365.
Version Control Systems (VCS) have been around for many decades within the software world but can be surprisingly new to some folks in the electronics design industry. This article will cover what a VCS is, what it does, and why you should be using one for your PCB design projects.
Designers often conflate leftover annular ring and pad sizes - they need to place a sufficiently large pad size on the surface layer to ensure that the annular ring that is leftover during fabrication will be large enough. As long as the annular ring is sufficiently large, the drill hit will not be considered defective and the board will have passed inspection. In this article, I'll discuss the limits on IPC-6012 Class 3 annular rings as these are a standard fabrication requirement for high-reliability rigid PCBs.
Sending a board out for fabrication is an exciting and nerve-wracking moment. Why not just give your fabricator your design files and let them figure it out? There are a few reasons for this, but it means the responsibility comes back to you as the designer to produce manufacturing files and documentation for your PCB. It’s actually quite simple if you have the right design tools. We’ll look at how you can do this inside your PCB layout and how this will help you quickly generate data for your manufacturer.
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.
