IoT Medical Product and Application Design: Challenges and Considerations
Ideally, any technology is going to drastically affect people and the ability of people to accomplish whatever tasks they need. Yet, when new technology is entering the medical domain, the stakes are always a bit higher: one has to be cognizant that any faults, errors, or malfunctions are going to immediately affect someone’s health. Granted, not every medical device is going to be life-or-death, but they should still be considered carefully

Constraint Driven Design versus Rules Driven Design in a Unified Environment
Wouldn’t it be great if more rules in life were checked automatically? I love to cook Italian food, but it gets tiring going back and forth between a cookbook and a pot of tomato sauce. The only automatic rules checking mechanism in the kitchen is your oven timer. Fortunately for PCB designers, high-quality software packages include constraint and rules checking features that can check your layout and schematic automatically. The ability to set

How to Create a PCB Layout from a Schematic in Altium Designer
You’ve done your usual excellent job of putting together the PCB schematic. The circuitry is defined and you are ready to go to PCB layout. But this time it’s a little different. Maybe your regular layout resources aren’t available, or perhaps you want to try to do your first layout yourself. Whatever the reason, you are ready to start working on the board side of PCB design, but you’re not sure how to create it from a PCB schematic in Altium

PCB Design Software: Creating a Bill of Material using Altium Designer
You’ve done it, your printed circuit board is finished and ready for PCB assembly. The schematic is finalized, the layout is checked and approved and you are ready to get this thing built. To do that though, you need to create a bill of materials. Fortunately, we are long past the days where these documents were created by hand. Every CAD system out there will automatically create a bill of materials through some library or other process. But

Role of the Embedded PCB Capacitor in Circuit Board Design
Mention capacitance, conductors, and dielectric capacitors in PCB to a 7th-grade science class, and you may see glazed-over expressions and hear bored sighs. I mean, hey, sometimes I get this with adults and coworkers I’m talking to so I can’t say I’m unsympathetic to the kids, but I have to promise them that circuits and circuit boards are, truly, fascinating. Let's help them answer the question: why are capacitors used in circuit boards? To

Five First Pass Perils in PCB Prototyping Runs
The first pass prototyping run for a new design is where its functionality really gets put to the test. The functionality of your PCB depends on the quality of the design you create in your CAD tools, but sometimes the prototype just doesn't function as intended. There are many possible reasons for this, which could be related to your design choices, the capabilities of your manufacturer, or both. Founders without hardware experience might

Via Aspect Ratio: Design, Signal Integrity, and Manufacturability
There is a certain beauty that exists in nature and can only be mimicked in PCB design. The golden ratio found in nature is a good example of a universal relationship that defines the aspect ratio of plants and animals. As with anything, PCBs can have layers to them: conductive layering, dielectric layers, barrier layers and with layers come drilling. And while via aspect ratios are no golden ratio, they have a beauty all their own and are

Design Planning with Differential Pair Routing Software and Directive Symbols
If the components on your PCB are like the organs in your body, then your trace routing between components are like blood vessels. What looks like a complex tangle of copper connections is actually a meticulously designed system that uses well-understood design rules. Your PCB design software can help you maximize your productivity while routing and prevent errors using directive designations. Great PCB design software doesn’t just let you set

CAD Layout Software for Modern PCB Design and Modern PCB Designers
Back in the day, PCB designers drew schematics by hand. Instead of guiding a mouse, technicians used red and blue pencils to carefully draw pads and traces on vellum parchment paper. Their tools included a triangle, a T-square, and templates. Forget a thorough design process involving CAD tools, full team collaboration, differentiated schematic diagrams and circuit board designs - one was lucky enough to have a steady hand. After completing a

Auto-Interactive Routing to Overcome Obstacles and Other Polygons
There’s no doubt about it, routing traces on a printed circuit board by hand can be a lot of fun. It’s an engaging challenge to make the routing as neat, tight, and correct as possible to give you the shortest routes with the best signal integrity. Once you are done you can take a lot of pride in knowing that your measured lines are perfect, you differential pairs are spot on, and everything looks great. The only problem is that level of manual

Dispel Confusion with Global Editing: Poor DxDesigner Usability Causes Confusion
The world has turned the corner from linear to organic. The need for global editing within versatile environments continues to grow. It used to be I could keep one file in my office drawer to collect bills for the month. When I got paid, it was a simple matter to list the bills, add them up, and write the checks. These days, bill paying goes much quicker on the computer. But I’ve had to adapt to different steps on each utility website and
