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.

Nine Dot Connects Nov. 29 Webinar: Spelunking in the Altium Schematic Preferences
November 21, 2017 | Nine Dot ConnectsEstimated reading time: Less than a minute
Join Nine Dot Connects on November 29 for a free webinar, "Spelunking in the Altium Schematic Preferences."
What’s interesting about the preferences in Altium Designer is that they provide options and flexibility, making the tool more customizable for the user. However, many of us do not go spelunking into the preferences because we do not feel we have full command of the tool, or we simply choose to accept the default settings. This defeats the purpose of the preferences.
It dawned on Nine Dot Connects that the preferences are a powerful feature of Altium Designer, but they are generally overlooked. They also realized that trying to show all the preferences in one hour would not allow the topic to be covered adequately. In this webinar, Nine Dot Connects' focus will be specific to the schematic preferences, and will demonstrate and explain all of these schematic preferences.
This free webinar will be held on November 29 at 2:00 pm Eastern.

Elementary, Mr. Watson: Ensuring Design Integrity
03/28/2024 | John Watson -- Column: Elementary, Mr. WatsonBack in February, many of us watched the "Big Game." It reminded me of the saying, “It's not how you start that is important, but rather how you finish." It is perfectly okay when you are talking about sports, you get off to a bad first half and need to recover in the second half. However, when it comes to PCB design, this is not a good practice. If things start badly, they usually don't recover. They continue down that same path, costing more money and losing design time.
The Pulse: New Designer’s (Partial) Guide to Fabrication
01/31/2024 | Martyn Gaudion -- Column: The PulsePCB designers fresh to the industry may think that once the schematic is loaded into CAD and routed out into XY data, the finished PCB is an “exact” copy of their XY data. That’s not an unreasonable assumption for basic designs. Here, I’ll outline some of a designer’s considerations related to signal integrity as designs become more complex.
Three Things to Improve High-Speed PCB Signoff, Part 2
09/27/2023 | Brad Griffin, Cadence Design SystemsAnother challenge for SerDes is losses within the channel design. At high speeds, dielectric material can be very lossy, making the appropriate selection of the right material, length, etc., critical for the channel. Many questions about stackup, trace widths, and height from the ground plane need to be defined up front. Simulating a signal with a topology explorer tool extracted from the design can be used to set up and run sweep parameters and push min/max length/spacing values into the Allegro schematic constraint manager (system capture).
An Overview of Rigid-flex Design
09/13/2023 | I-Connect007 Editorial TeamFor this month’s issue on rigid-flex design, we spoke with instructor Kris Moyer, who teaches the IPC class “PCB Design for Flex and Rigid-Flex Boards.” In this wide-ranging interview, Kris breaks down the hurdles facing rigid-flex designers and offers a variety of solutions for rigid board designers taking on their first rigid-flex circuits. He also provides a few horror stories to illustrate what happens if you don’t follow sound design practices, rules, and standards. And, as Kris points out, “Your fabricator is your friend.”
Elementary, Mr. Watson: Circuit Simulation, SPICE, and AI
08/21/2023 | John Watson -- Column: Elementary, Mr. WatsonAccording to the Federal Aviation Administration’s flight time limitations and rest requirements, a commercial pilot is restricted to 36 flight hours in a week, 100 hours in 28 days, and 1,000 hours in any calendar year. But before these pilots even start flying the friendly skies, they spend considerable time in a flight simulator. In the same way, PCB design and circuit simulations provide the same advantages: a controlled, safe environment for testing a circuit without the considerable overhead of fabricating and assembling the PCB.
