Current IssueLevel Up Your Design Skills
This month, our contributors discuss the PCB design classes available at IPC APEX EXPO 2024. As they explain, these courses cover everything from the basics of design through avoiding over-constraining high-speed boards, and so much more!
Opportunities and Challenges
In this issue, our expert contributors discuss the many opportunities and challenges in the PCB design community, and what can be done to grow the numbers of PCB designers—and design instructors.
Embedded Design Techniques
Our expert contributors provide the knowledge this month that designers need to be aware of to make intelligent, educated decisions about embedded design. Many design and manufacturing hurdles can trip up designers who are new to this technology.

Cadence Continues ‘Left Shift’ of SI Functions
02/29/2024 | I-Connect007 Editorial TeamAt DesignCon, the I-Connect007 Editorial Team met with Brad Griffin, product marketing group director for the System Analysis Group at Cadence Design Systems. Brad explains how this analysis tool enables designers to address SI and PI issues early in the design process, before they become costly errors, and why he believes his late co-worker Dennis Nagel would be proud to see his efforts come to fruition.
Beyond Design: Embedded Capacitance Material
02/22/2024 | Barry Olney -- Column: Beyond DesignEmbedding components into the multilayer PCB substrate can have many benefits, including reduced board size and improved signal integrity. However, embedded capacitance material (which is not really a component but rather part of the substrate) can improve power integrity dramatically by reducing AC impedance and generally enhancing the performance of the product. It takes up no additional space, is easy to implement (because it is compatible with standard FR-4 processes), and can be cost-effective.
BOOK EXCERPT: 'The Printed Circuit Designer’s Guide to... Stackups—The Design within the Design', Chapter 5
01/30/2024 | I-Connect007 Editorial TeamWe are sharing this sample of 'The Printed Circuit Designer’s Guide to... Stackups—The Design within the Design,' by Bill Hargin, to give our readers a glimpse into the important topics that are covered in this book. He writes, "In my work, I deal with impedance and the entire ecosystem surrounding it daily. Whenever I talk to hardware teams, they often ask me the question of how two fabricators can come back with two totally different designs for the same target impedance.
Connect the Dots: Controlled Impedance and Calculations for Microstrip Structures
12/28/2023 | Matt Stevenson -- Column: Connect the DotsModern high-speed and RF PCB design is an exciting field but comes with its own set of challenges. Signal integrity, performance, and crosstalk become major concerns. Designers for these types of projects need to learn how to control electromagnetic interference (EMI) and compatibility (EMC), which means utilizing some interesting math and calculations.
Elementary, Mr. Watson: Consider Physics When Designing Non-traditional Geometries
12/28/2023 | John Watson -- Column: Elementary, Mr. WatsonElectronics have profoundly impacted society, shaping how we live, communicate, work, and entertain ourselves. Nearly every aspect of our lives is affected by electronics in some way. If you want proof, sit and watch people in public; everyone is on a screen. The communication revolution alone has transformed our lives, enabling instant global connectivity. Some would argue these advances come with their distinct disadvantages.
