Transmission Line Reflection Coefficient View a numerical example of the transmission line reflection coefficient and how simulations can help you understand the results. Read Article IC Thermal Analysis: Thermal Management for Integrated Circuits As anyone who designs and builds electronic devices knows, the device will generate heat when it’s switched on. Wherever current flows through an impedance, energy losses will manifest themselves as heat, thanks to thermodynamics laws, whether in components, connections, wiring, or the PCB. The greater the loss, the greater the excess heat generated. While components with thermally enhanced packages are available to help manage any heat generated Read Article Moisture Sensitivity Levels in Electrical Components A range of materials used to construct electrical components can absorb moisture from the air over time. This initially became a problem with introducing reflow soldering, where the components are subjected to sudden high temperatures over a short period. This was then exacerbated with the switch to lead-free solder, which resulted in higher peak temperatures during the reflow process. Other factors that have increased the prevalence of moisture Read Article How to Automate Electronic Component Data Tracking Today’s design tools can help automate collection and tracking of electronic component data. Here’s how Altium Designer keeps your components healthy. Read Article Real-World Monitoring with Encoders Electrical devices don't tend to be useful unless they can interact with the real world, taking measures, producing outputs, or responding to events, for example. One functional ability that devices may require is the capability to measure physical movement. This may be a wheeled vehicle traveling across a surface or a fixed machine's shaft rotation. An encoder is a sensor that turns a position into an electrical signal. This position may be Read Article Best Practices for Using PCB Reference Designs Reference designs can help you get started building a new system, but watch out for these pitfalls if you plan to use reference designs for your PCB.

Altium 365 gives you both options in your web browser or within Altium Designer. Read Article 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, as we saw in the previous section, the line stabilizer initially converts some of the useful power into heat, which makes the efficiency of the line stabilizer less than 100%, and it is expected for technical systems. Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with Read Article Anatomy of Latitude Part One: Pulse Width Modulation (PWM) as a Result of the Evolution of Linear Systems Great Ideas and Smart Solutions 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. Great ideas and ingenious solutions are found and applied in this area probably more than in other engineering fields. The greatest example is the use of Pulse Width Modulation (PWM) signals Read Article Power Supply Schematic Design in Altium Designer Whether you’re designing a bench power supply for an electronics lab, or you need to design an embedded power supply for an IoT product, you’ll need some world-class PCB design tools.

Read Article A Review of PCB Thermal Resistance Management with Thermal Vias Design of PCBs and thermal management are intimately linked as thermal problems are known to significantly reduce the useful lifetime of a circuit board and components. Heat that is generated in a circuit board by active and passive components tends to be confined near the components, leading to a high-temperature increase due to the low thermal conductivity of most circuit board substrates. Frequent cycling of a circuit board and components Read Article PCB Thermal Resistance: Theory and Management The thermal conductivity of your PCB material stackup and arrangement of copper conductors are important factors that determine the thermal performance of your circuit board. You will likely need to include strategically placed thermal vias, a heat sink on each active component and power electronics, and active cooling measures near any other heat source on your circuit board. Copper in printed circuits has high thermal conductivity, while FR4 Read Article Thermal Conductivity and Thermal Management for Printed Circuit Boards The physical properties of your PCB substrates and copper conductors are the primary factors that determine how it will perform under pressure.
