Important Considerations in Your Embedded System's Master-Slave Communication Model
It can take a few weeks or months to finish a working prototype of an embedded system. Sometimes I would spend days working on a single part of the project. However, when your boss is looking for updates every day, it can be particularly distracting and hinder your productivity. When I started my design company, I learned not to repeat these mistakes on my team. Like a human, embedded systems come in various shapes and sizes, and more importantly

Bill of Materials in Supply Chain Management: Part Inventory Control
Sending information to other departments and personnel is a regular part of the PCB design process. For purchasing, their part of this process starts when engineering sends them a bill of materials () for a new design. At this point in the design cycle, the is a preliminary document and it is constantly changing as are added, updated, or eliminated during the design cycle. The problem for purchasing is that this constantly changing data impacts

PCB BOM Management: Spend Less Time on Your BOM and Reduce Delays in Manufacturing
Real-time solutions with management tools Cafeterias in colleges, summer camps, and schools are often known for serving up food that has a consistent quality and similar ingredients. For the kids who are tired of eating spaghetti with meatballs, this approach to food production is a downer. However, from a manufacturing point of view, using standard ingredients with minimal variety makes for efficient production. This is also true in circuit

PCB Circuit Design Tips: Standard vs. Specialized Component Selection in PCB Design
As a kid, I was fascinated by hovercrafts. These nearly frictionless vehicles go from land to water without pause and spin 360s on demand like a carnival ride. I knew that the cost of a full-scale build would require mowing every yard in the county, so instead, I started by constructing a homemade radio-controlled model. It worked beautifully on ponds and flat parking lots, but in our hilly corner of the woods, the sleek craft required all of the

PCB BOM Management Tools and Real Time Part Access: How It Will Help Your Design for Manufacturability
Have you ever been so ready to take off on a new project that you can’t wait to jump into it? Of course you have. As engineers that’s part of what makes us tick. We’ve got so many ideas running around in our head that we would rather forego sleep or food in order to create a design. Then it happens, some kind of delay forces us to lock up the brakes on our creative process. There are many scenarios that can do this, but one of the worst is when

Circuit Board Design and BOM Management in Low Volume PCB Assembly
What’s the difference between Angry Birds and SpongeBob? I’m probably at an age where I shouldn’t be caring about these things, but choosing the wrong character for my son’s 5th birthday cake could spell disaster. As a designer, you probably can’t relate to my need to carefully consider the repercussions of choosing SpongeBob. However, you might understand it better knowing that I apply the same level of caution when designing for low volume

BOM Automation: The Benefits of Having an Automated Bill of Materials in Project Management
I have some friends who founded a startup company to create and market a brilliant new product. Their product quickly became a success, but all their hard work was constantly undermined by communication issues between departments. It wasn’t long until the engineers found their creative hands tied, purchasing was buried under an avalanche of unreliable documentation, and the product build-in manufacturing was slowed to a crawl from incorrect and

Using Flyback Diodes in Relays Prevents Electrical Noise in Your Circuits
What is a flyback diode, and how does a flyback diode protect a circuit? When used properly, flyback diodes can reduce electrical noise and prevent flyback voltages from building up.

The Benefits of a Bill of Materials In Supply Chain Management
Some of the most complicated engineering projects I’ve worked on were made up of multiple layers of sub-assemblies. Before we could order parts for a new assembly, we needed to go through every component in each tier of the final product to ensure that they would meet the rigorous current, voltage, and temperature derating requirements for different customer applications. The first few times I had to do this, it was by merging dozens of excel

BOM Part Number Management: Why It Should Be Automated
If you’ve ever worked with high voltages or have designed a high voltage circuit, you know that they always require careful planning. In my last job, we had been using a particular high voltage power supply circuit for years. When it was initially designed, the board took longer than usual to complete. While its design required some extra finicking, it was worth the effort. Everything was going well until the larger assembly's design was modified

Important Features to Consider When You're Comparing and Recomparing PCB Design Software
Anyone who knows me knows that I hate shopping. This is as true for lab equipment and software as it is for clothes and cars. At my lowest of lows I’ve had meltdowns in the mall, and had to call a cab while my friends were still going strong. Now when I shop, I like to get something as close to perfect for me as possible, so that I don’t have to repeat the experience for a long time. So, if I’m looking for ECAD software, what features and support

Altium Vault Design And Library Migration Guide
LIBRARIES AND DATA This guide provides insight into design project migration into Altium Vault. Library Management in Altium Vault is inspired by modern data management systems. Rather than simply lists of components, their designs are enriched by revisions, lifecycle management and traceability of relationships between models, components, library files, and projects. Altium Vault Design and Library Migration Guide Centralization is also improved

Complete Component Library Management for PCB Design Data
Complete Management Components are the basic building blocks of designs and even the slightest discrepancy can derail your whole design process. If one bad footprint makes its way through manufacturing, the rest of your design can be invalidated with necessary layout changes. Worst of all, you’ll have to identify everywhere a bad component has been utilized across several designs. The work required to change your layout grows exponentially the

The Best Static Analysis Tool For Developing Autonomous Vehicle Software
If only it were this easy. Designers often focus on benchmarking their compiler, only to have their programs slowed down by safety considerations later. Using a compiler that has integrated safety features, especially static analysis tools, can get your program into ISO 26262 compliance quickly. Using a safety tool with great static analysis can save you time in debugging, keep you from cutting features, and allow you to get the most out of your

Choosing the Best Communication Configuration for Your IoT Device Network
Not planning your IoT system communication adds cost and adventure to installing your products. It’s all set, you have perfected the design of the latest state-of-the-art IoT fork and you’re feeling unstoppable. Nothing could throw a wrench in your plans now...except maybe your fork's network connection. What’s the difference between a smart fork that can't connect and an ordinary fork? You paid a lot more for the smart one! That’s why it’s

Don't Write Your Own Libraries for Advanced Driver Assistance Systems Applications
Have you ever tried renovating your house on your own? Replacing floors and windows, painting walls and cabinets. You know, all the things the experts should be doing. In my opinion, the only thing worse than doing your own renovations is writing your own libraries for advanced driver assistance systems (ADAS) applications. Our team once had to write our own libraries. It took up an enormous amount of time on the front end. Later, when we had

Data Management - Pain Point Assessment
It’s that phase of the project when you’re about to hand over a development released product to production. From the development perspective, everything, from designs, parts, models, BOMs, and documentation, are all in their release state. It’s a time that calls for a true celebration after weeks of sleepless nights to finish the design on time and within budget. Then you get the flash back with few what-if questions; did sourcing get the new
