Altium VP, Lawrence Romine on Altium Designer 20 In this episode Altium VP shares the features you can expect from Altium Designer® 20? The star of AD20 is undoubtedly interactive routing–and is already being received exceedingly well. Watch it here Read Article Assuring Design Coherence in a PCB Introduction There is a saying “that it’s not how you start that is important, but rather how you finish.” Which is perfectly ok when you are talking about sports and you get off to a bad start need to recover in the second half. However, when it comes to PCB design, it’s not a very good practice. If things start badly, they usually don’t recover, and it continues down the same path—which ends up costing more money and lost design time. At one Read Article Concord Pro and Component Creation Altium Concord Pro™ as a standalone product and brand name has been discontinued and the capabilities are now available as part of our Altium enterprise solutions. Learn more here. Introduction First off, before I say anything, the more that I have been using Altium Concord Pro™, the more I like it. In fact, I love it. Altium has surprised me many times with the quality of the tools they put out. A few examples: Draftsman®, ACTIVEBOM® or Read Article Never Underestimate the Power of a Mock-Up The ability to do a 3D mock-up within your design software, is an invaluable tool that no doubt has prevented countless re-designs and revision changes. This is particularly powerful in the world of flex and rigid flex. When the circuit is intended to be bent, folded, or formed it is very easy to make a mistake with pinouts and orientation. Before the power to model this within the design tool, paper-dolls and mylar cut outs were often used to Read Article The Newest Advances in EDA: Modular Electronics Design EDA has come a long way since the 1960’s. Image source: Autodesk Before the birth of EDA, circuit boards and integrated circuits were all designed by hand or some other manual process. The need for more advancement in electronics design made clear the need for automation, a transition which took roughly 10 years and began with drafting in the mid-1970s. The publication of “Introduction to VLSI Systems” by Carver Mead and Lynn Conway in 1980 paved Read Article What is the Electrical Return Path in a PCB? One of the fundamental aspects of any circuit diagram is the return current path or electrical return path. In a circuit diagram and a schematic diagram, the path the current follows to return to the low potential side of a power source should be obvious, but it may not be so obvious in a PCB. To quote the great Eric Bogatin at his PCB West 2019 presentation, the distinction between a schematic diagram and a PCB layout lives in the white space of Read Article Common SMT Defects to Avoid During Soldering As more designs are using smaller components with surface-mount pads, Surface-mount Technology (SMT) soldering defects can mount and impact yields due to various design and manufacturing problems. These problems may have been minor and had a negligible effect on yields in the past, but they can cause rework costs to mount quickly and should be avoided. Here is a basic SMT defect list you can avoid during design and assembly. Bridging Between Pads Read Article PCB Design For Test Structures And Tests Performed, Part 2 In Part 1 of my article I outlined the various test structures that can and should be incorporated into any given PCB design. Included in this was a description of how they are built, where they are located and how they are used to ensure PCB structural and performance integrity. As speeds have increased and designs have become much more complex, test structures have become a necessity rather than features that can be added indiscriminately. And Read Article PCB Design For Test—Test Structures And Types Of Tests, Part 1 An important part of any high-speed design is making sure it can be tested successfully during manufacture and operation. Since these tests are performed significantly downstream from the PCB design process, they are not often properly and thoroughly accounted for as part of this process. This article will address two important aspects of the design for test process: creating test structures (aka test point connections) within the board, and Read Article Communication from Design to Assembly In a perfect world, a box and enclosure are designed, and then printed circuit boards or flexible circuits are designed to fit within that box perfectly, meeting all the electrical and mechanical requirements of the project. Sadly, most of us don’t get to work in that perfect world and at times must deal with challenges to that original plan. Things don’t always work as expected. Sometimes that is because something obvious was missed., Often it’s Read Article Data-Over-Sound Open Source: Chirp Unlocks the Power of Sound Chirp sends data seamlessly over soundwaves (Image source: chirp.io) According to the Wikipedia, a chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. It’s also the name of a rather interesting company, whose website can be found at Chirp.io I don’t know about you, but – until recently -- if someone were to ask me how to transmit data from one device to another, my knee-jerk reaction would have been Read Article Advancements in Electronic Component Management In this volatile business of ours, we can ill afford to rest on our laurels, even to pause in retrospect. Times and conditions change so rapidly that we must keep our aim constantly focused on the future. - Walt Disney I stood at the large hospital window looking out at the early evening sky. I could see several stories below just a small section of the nearby freeway. As typical for the late hour, the traffic was at a standstill, with its Read Article How to Use Altium Designer Most Efficiently One of the things I really love about Altium Designer® is how many shortcuts there are, and how customisable they are. A while ago in my database library’s chat channel, there was a really good discussion about shortcuts and how each of us customises his or her menus to be able to draw schematics and layout boards as quickly and efficiently as possible. Many of us use and love similar shortcuts, but there were enough interesting use cases that I Read Article Fabulous Folding Phones Microsoft doubles up with its dual screen Surface Duo (Image source: Microsoft) I like to think that I'm riding the crest of the technology wave, but every now and then something slips past my eagle eye and then leaps out to surprise me when I least expect it. Such was the case when I ran across the fact that Microsoft is planning on rolling out a fabulous folding smartphone called the Surface Duo in 2020.

The progression of industry and manufacturing throughout the past 250 years A report from the M cKinsey Global Institute estimates that IoT devices could have an annual economic impact of $3.9 trillion to $11.1 trillion across many different settings by 2025, including factories, cities, retail environments, and the human body. IoT devices can be used to gather and process information remotely, either for automation or analysis purposes.

In the not-so-distant future, the goal is to use devices like these to provide organ-to-cloud data connections that will allow clinicians and physicians to monitor our health and determine the effectiveness of Read Article Great Spock!

We’ll call her Rachel (because that's her name). Rachel is extremely allergic to almost any form of shellfish. The slightest hint of a sniff of a mollusk, crustacean, or echinoderm will leave her gasping frantically for air and grasping feverishly for her EpiPen.
