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.

Elementary, Mr. Watson: Rein in Your Design Constraints
July 10, 2025 | John Watson, Elementary, Mr. Watson

I remember the long hours spent at the light table, carefully laying down black tape to shape each trace, cutting and aligning pads with surgical precision on sheets of Mylar. I often went home with nicks on my fingers from the X-Acto knives and bits of tape all over me. It was as much an art form as it was an engineering task—tactile and methodical, requiring the patience of a sculptor. A lot has changed in PCB design over the years.
Study on Resonance Mitigation in Metallic Shielding for Integrated Circuits
July 8, 2025 | Maria Cuesta-Martin, Victor Martinez, Vidal Gonzalez Aguado, Würth Elektronik

Inherent cavity resonant modes often lead to significant degradation of shielding effectiveness, responsible for unwanted electromagnetic coupling. Cavity resonant modes of the metal shielding enclosure can produce two adverse problems: the mutual coupling among different RF modules and shielding effectiveness reduction of the metal enclosure. The cabinets serve to shield certain components from electromagnetic interference (EMI). However, these cavities present some resonance peaks at 5 GHz, making it impossible to use them at higher frequencies.

Target Condition: Are Autorouters Friend or Foe?
July 1, 2025 | Kelly Dack, Target Condition
For PCB designers, just hearing the word “autorouters” can trigger everything from eye rolls to heated debate. We all have stories—some painful, some comical—of boards gone sideways at the hands of an overzealous routing...
Fresh PCB Concepts: Assembly Challenges with Micro Components and Standard Solder Mask Practices
June 26, 2025 | Team NCAB, Fresh PCB Concepts
Micro components have redefined what is possible in PCB design. With package sizes like 01005 and 0201 becoming more common in high-density layouts, designers are now expected to pack more performance into smaller spaces than ever...
