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.

EMA Webinar: How to Design with Supply Chain in Mind
March 7, 2019 | EMA Design AutomationEstimated reading time: Less than a minute
BOM denied: Redesign required. These are four words any engineering team dreads. You spent countless hours designing, crafting, and testing your product to perfection only to have everything put in jeopardy due to component sourcing issues.
Obsolete parts, RoHS / REACH compliance issues, inadequate stock—almost every engineer has been bitten by one of these issues at some point. What's worse is these issues often result in some sort of late-stage redesign. Fortunately, it doesn’t have to be this way.
On March 14 at 2 pm Eastern Time, join EMA Design Automation and SiliconExpert for a free webinar that focuses on the common causes of BOM rejection and how to prevent these issues in the future.
What attendees will learn:
- Common reasons for your design and BOM to be rejected
- The impact of these issues (on engineering and the overall chance of your products success)
- How to avoid spec’ing in unorderable / obsolete / non-compliant parts at the design stage
- How to generate supply chain ready ‘Zero-Touch’ BOMs as an inherent part of your design process

Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.

The Shaughnessy Report: Showing Some Constraint
07/14/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportWhen we first decided to cover strategies for setting PCB design constraints, one designer we spoke with said, “They’re not really constraints; they’re more like guardrails that prevent your design from going off a cliff.”
