Three Methods for Building MCAD Ready Components

One of the most difficult and frustrating things to arise when traveling to a foreign country is the language barrier. Communicating a simple greeting can sometimes seem like a big hassle. The same thing is true for different CAD tools. When your tools aren’t speaking the same language, you’re going to run into problems. Bridge this gap by building out your component libraries with everything it takes to truly define a component, including 3D models that seamlessly propagate into the PCB editor and beyond.

Reflectionless Matching vs. Conjugate Matching: An Apparent Contradiction

There is one confusion related to impedance matching that comes up again and again, and it appears to be a fundamental confusion between reflection and power delivery. This leads to an apparent contradiction that arises when we try to generalize power delivery to wave reflection, despite the fact that the two were not meant to be related.

Impedance Calculations: Differential Pairs

Altium designer makes it easy to calculate geometry when you need to calculate impedance for differential pairs. We’ll go over how differential pairs can help with a two layer and multi layer board, as well as what types you can create such as differential co-planar, and how to configure them for your specific design.

Quarter-Wave Transformer Design For Real and Reactive Loads

RF systems operate with specific impedance values across entire interconnects, including on PCBs. Not all RF components are packaged in integrated circuits with defined impedances, so impedance matching circuits and line sections are needed to ensure signal transmission between different sections of an interconnect. One of these impedance matching techniques is the quarter-wave impedance transformer, which can be implemented as a printed trace with specific impedance.

Component Warpage Causes in a PCB

A staff member at a PCB manufacturer once explained to me that they thought we were having an issue with a package warping. Unfortunately, component warping can occur both in a PCB and in components. In this article, we'll give an overview of warpage in a PCB, specifically in the circuit board and in the components.

8 Reasons to Store Your Components in Altium 365

Working with local libraries seems like a simple solution, but we often don’t take into account the added time spent maintaining libraries and sharing them between team members. There is no good way to avoid duplicate efforts with component creation and no standardization to ensure consistent naming. Worst of all, there is no way to identify the latest component revision, and library files can be easily corrupted or misplaced. This webinar showcases the advantages of component storage in Аltium 365 to resolve the issues of local libraries and component management.

Link Budget Calculator

RF Signal Chain and Link Budget Basics

If you're designing a wireless IoT device, and you know how to calculate the link budget, you can reasonably estimate whether your signal will reach its destination and be read by the receiver. To calculate the link budget, the designer needs to know something about all other sources of gain and loss in the system. Once link budget is determined, the designer can judge whether some modification is needed in their RF signal chain.

How to Calculate SMD Pad Sizes?

Best Methods for Calculating SMD Pad Size in PCB Design

SMD components require precisely sized pads for soldering during assembly. The designer is responsible for ensuring pad sizes are correct, either by calculating them and comparing with footprint data, looking through datasheets, or by memorizing SMD pad size standards. If you have a component and you don't have access to the footprint, and you decide to biuld the footprint yourself, what resources are available to ensure you have the correct pad size?

Can You Fix a Warped PCB?

Can You Fix a Warped PCB?

Before we get too deep into this article, I’ll give you the simple answer. You probably can’t fix warping in your PCB after it’s already been fabricated. You can prevent an unwarped board from becoming warped during assembly, but only as long as materials were selected properly and the board is put into reflow correctly. We’ll run over some of these points in this article, and I’ll examine some points that might help you recover a warped board.

Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy

We continue to explore the magic of energy conversion in a PWM transducer. Why is it magic? Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with scissors, cuts the “fabric of energy” into pieces, and then, like a sewing machine, stitches the pieces of energy into a dress - DC Magnitude. What is a constant component and how can we get it? Let's explore!

Anatomy of Latitude Part One: Pulse Width Modulation (PWM) as a Result of the Evolution of Linear Systems

There are different techniques in the world of technology to achieve various goals, both final and intermediate. Some techniques are so successful that they are commonly used with high efficiency. Electronics is no exception. The greatest example is the use of Pulse Width Modulation (PWM) signals (energy), which is applied in any modern electronic device. To apply PWM effectively, it is necessary to understand the engineering difficulties that engineers faced in the past, and the thoughts and ideas that subsequently were combined into effective, complete PWM power solutions.

What Influences Electrolytic Capacitor Lifespan?

If you speak with a bunch of design engineers, you might quickly form the opinion that the electrolytic capacitor has a particularly dubious reputation. A faulty electrolyte mix used in these types of capacitors led to premature device failures, and quite often, a “bit of a mess” was made to the PCBs on which they were soldered. However, despite the problem of the capacitor plague, this article is focusing on helping the designer understand how to get many more years of useful life from an electrolytic capacitor.

Best Practices for Sharing PCB Files vs. Sharing PCB Projects

Even though today’s cloud platforms are immaculately secure and they allow a range of files to be easily shared, there are times where you should limit the data you’re sharing to only the critical files required. For PCB designers, this means either sharing entire design projects or sharing individual files with your manufacturer, customers, contractors, or collaborators. If you want to eliminate liabilities and keep your team’s design data secure, consider these best practices for sharing PCB design data with Altium 365.

Best Practices for Using Reference Designs

Best component companies will release reference designs for their new and legacy products to show designers an example application for a component. If the reference design is good enough and it very nicely illustrates how to quickly engineer around a few main components, I’m likely to use them in the design and the component maker has just earned my business. If you’re a newer designer and you’re wondering whether reference designs are right for your next project, follow these best practices so that you don’t make any mistakes with your reference design.

Your Complete Guide to Via Stub Analysis

Via stubs are sometimes viewed as an annoyance, especially when you only need to make a transition between adjacent layers. For low speed, less-dense boards with low layer count, via stubs are an afterthought, or they may not receive consideration at all. For faster edge rates/higher frequencies, the conventional wisdom is to remove all via stubs. The question is: what exactly counts as “high frequency,” and how do you figure out the relevant length?

Keeping Your Circuits Dry

For the home hobbyist, protecting their electrical devices usually means keeping the coffee cup or soda can away from anything that carries a large voltage.

However, what do you do if the fantastic new device you’ve designed needs to work in a humid, damp, or dripping wet environment?
