    The Role Of ISU Petasys, A Multilayer Manufacturing Company in Realizing a Successful PCB Implementation John Stephens, Senior Vice President of Sales for ISU Petasys (pronounced “E-soo”), built his first circuit board in 1974. Like many others of us in the industry, he got a first-hand education in PCB design, and manufacturing and assembly by working in the aerospace industry. He explains, “I started in aerospace at Litton Guidance and Control Systems, where I worked in a process development lab that was basically a prototyping shop where we Read Article
    37:20 Efficient PCB Routing Using Gloss and Retrace Tools The primary goal of your traces is to carry signals throughout your board without losses. To do this properly, you Watch Video
    Reflecting on Your Design, Part 2, What Do Reflections Do to a Signal? In part 1 of this article, I described what transmission line reflections are, how they are created and what the resulting waveforms look like. This part of the article will discuss what reflections do to a signal. Figure 1 is a typical 5V CMOS driver driving a 50-ohm transmission line that is 12 inches or approximately 2 nanoseconds long. There is a CMOS receiver at the end of the line that is a tiny parasitic capacitor. For these purposes, it Read Article
    Transmission Line Properties That Affect Impedance—Hidden Features Here and in several other articles published on the Altium Resource section of the company’s website, the topic of transmission line impedance has been addressed from a number of different perspectives. I have addressed transmission line impedance previously in my article, The Evolution Of Simulation Technology and Impedance and, it might seem that we may have exhausted the field of potential information that can be provided on impedance, however Read Article
    The Right Termination, Of The Right Size, At The Right Place In recent articles, I have addressed reflections, what they do to signals on transmission lines and how to control them through the use of terminations, serial and parallel. One area of confusion that continues to come up in our on-site classes regards the actual placement of terminators. This article will address this topic and hopefully provide some useful guidelines. Note: I am only addressing series and parallel terminations. Most of the Read Article
