Current IssueShowing Some Constraint
A strong design constraint strategy carefully balances a wide range of electrical and manufacturing trade-offs. This month, we explore the key requirements, common challenges, and best practices behind building an effective constraint strategy.
All About That Route
Most designers favor manual routing, but today's interactive autorouters may be changing designers' minds by allowing users more direct control. In this issue, our expert contributors discuss a variety of manual and autorouting strategies.
Creating the Ideal Data Package
Why is it so difficult to create the ideal data package? Many of these simple errors can be alleviated by paying attention to detail—and knowing what issues to look out for. So, this month, our experts weigh in on the best practices for creating the ideal design data package for your design.

Nine Dot Connects Webinar: What Qualifies a Circuit as High Speed?
August 22, 2017 | Nine Dot ConnectsEstimated reading time: Less than a minute

Technologists at Nine Dot Connects have been asked the following question many times: "What's the frequency in which a design is considered to be high speed?" Would it surprise you to know that a 10 MHz design which could be wire wrapped or placed on a protoboard could constitute high speed? The fact is, frequency is only a part of the story.
The bigger question is, "What factors qualify the circuit as high speed?" Issues such as EMI, crosstalk, receiver noise floor, and signal propagation all come into play. It is not just a matter of avoiding or mitigating these issues; it's about optimizing the communication path.
This August 30 webinar will focus on exactly what qualifies a circuit as high speed. Sean Kelly, who has provided several introductory webinars on the topic of high speed in the recent past, will be presenting.

Target Condition: The 5 Ws of PCB Design Constraints
07/29/2025 | Kelly Dack -- Column: Target ConditionHave you ever sat down to define PCB design constraints and found yourself staring at a settings window with more checkboxes than a tax form? You’re not alone. For many designers—especially those newer to the layout world—the task of setting up design constraints can feel like trying to write a novel in a language you just started learning.

Creating a Design Constraint Strategy
07/24/2025 | I-Connect007 Editorial TeamMost designers learn how to set their design constraints through trial and error. EDA vendors’ guidelines explain how to use their particular tools’ constraints, and IPC standards offer a roadmap, but PCB designers usually develop their own unique styles for setting constraints. Is there a set of best practices for setting constraints? That’s what I asked Global Electronics Association design instructor Kris Moyer, who covers design constraints in his classes.
Elementary Mr. Watson: Closing the Gap Between Design and Manufacturing
07/23/2025 | John Watson -- Column: Elementary, Mr. WatsonModern PCB designers are not merely engineers or technicians. I believe that PCB design, at its core, is an art form, and modern PCB designers should be considered artists. Beyond the technical calculations and engineering rules lies a creative process that involves vision, balance, and a passion for what we do. Like any artist who works with brush and canvas or chisel and stone, a PCB designer shapes invisible pathways that bring ideas to life. Each trace, layer, and component placement reflects thoughtful decisions that blend form, fit, and function.
