Nothing’s Perfect: Tolerance and the IPC PCB Dimensions: Tolerance and the IPC Here's where we boldly confront a grim reality - nothing is perfect in the real world. We do our best to maintain accuracy in our circuit board designs, but the manufacturing process produces imperfections. Our CAD systems assume a drill is perfectly centered in a round pad. It never is. We declare specific trace widths, and when we measure them on an actual board they are always slightly thinner or thicker than expected. Multiple layers are Read Article
IPv6 and the Internet of Things IPv6 and the Internet of Things For a while now we’ve been told that IPv4 addresses (you know, the network addresses that look like 192.168.1.1) are running out. and, approximately three decades from now, there aren’t going to be enough of them left to go around. While we have reached the point of IPv4 being fully allocated at a high level, it's still easy to buy or lease IP addresses in any region, and ISPs are not turning down new customers because they cannot allocate them Read Article
Autonomous Device for the Preventive Measurement of Soil Condition Autonomous Device for the Preventive Measurement of Soil Condition My name is Piotr Lazarek. I’m a second-grade student of the secondary school “Filomata” in Gliwice. For over 5 years, I have been interested in physics, informatics, and technology. One year ago, when I was thinking about the focus of my project, I considered the idea of building a Mars rover. After further thought, I realized that there are dozens of competitions around the world in which hundreds of such vehicles have already been presented. I Read Article
Culture Shock: Agile and Individual Engineering Accountability Culture Shock: Agile and Individual Accountability for Mechanical Engineering An engineer's prime responsibility has traditionally been to design products for form, fit, and function. It's worked just fine, or well enough, up to this point, right? Well, that depends on how you look at it. A substantial percentage of organizations today report missed deadlines, delayed projects, or canceled projects altogether. Products are changing, and this brings new challenges to the industry. They're becoming less mechanized and more Read Article

Passive Intermodulation in PCBs for 5G Systems Passive Intermodulation in PCBs for 5G Systems 5G networks are coming. Are your PCBs ready? Anyone pays attention to the top bar on their phone has noticed the 4G indicator. If you use a major wireless carrier in the U.S., you’ll likely see 5G in the top bar once you buy your next smartphone. 5G systems designers, especially PCB designers, will need to work with higher frequencies, faster data rates, lower power budgets, and plenty of other performance requirements. Nonlinearity will also Read Article
