Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

Digi-Key's Free Online Resources Meet Student Design Challenges
October 13, 2017 | Digi-KeyEstimated reading time: 2 minutes
Creating and maintaining a complete online portfolio of free, easy-to-use engineering tools, including a full suite of low-cost EDA and design tools, is one way Digi-Key Electronics, a global electronic components distributor, continues to support future engineers throughout their education.
Digi-Key Tools and Resources
The design tool solutions are formulated to help designers at all levels through the entire design cycle to shorten the time from design to production. The portfolio includes free diagramming tools all the way to the most robust professional full PCB schematic capture and layout functionality.
Digi-Key offers four unique and complementary tools:
- Scheme-It: The company's circuit drawing "back-of-the-napkin" tool provides the ability to diagram at the Block, Icon, System, or Schematic level. With easy access to parts and data this is a great tool to start designing with in college.
- Mentor PADS Maker/MakerPro: Professional, industry-proven PCB design tools from Mentor, now a Siemens® business, that offer FREE and low-cost perpetual licenses. Mentor PADS Maker tools can grow with you from your basement all the way into the billion-dollar business after graduation.
- Quadcept: This tool offers a free student/maker version, yearly or monthly licensing for convenience, advanced processing tools for ERC/DRC, and an intuitive and easy-to-use UI for an easier and low-cost switch.
- Ultra Librarian: Contains automated and manual footprint, symbol and 3D model creation for about 90% of Digi-Key-covered parts, and access to a database of pre-built library parts that export to most CAD formats.
Other helpful tools students will find on the Digi-Key website include:
- Reference Design Library: Search and compare from manufacturer-provided reference designs
- Conversion Calculators: Include tools for converting temperature, pressure, capacitance, resistance codes, and more
- Video Library: Learn from a variety of tutorial videos, how-to demos, just-for-fun electrical project ideas, and/or humorous tech videos
- BOM Manager: Import your Bill of Materials, name and save your BOMs, and share your designs
- Article Library: From in-depth design to how-to articles, Digi-Key's Article Library will keep you updated on the latest technologies
"Tools are the place where all designers must spend some time to get the project brought into reality. Digi-Key would like to make that process as easy as possible with the greatest efficiency while working in those tools," said Jeremy Purcell, Program Manager - Digital Design Tools, Design Support at Digi-Key. "We provide students with tools that will help them in all aspects of the design process. We aim to grow our content as you grow your ideas. Together we can build lots of great things."

Designing Without a Rulebook: When Engineering Becomes Innovation
05/05/2026 | Stephen V. Chavez, Siemens EDAWhat if the very rules that made you successful as a PCB designer are the ones now holding you back? This reminds me of walking the floor and attending sessions at both PCB West 2025 and APEX EXPO 2026, where one common theme stood out: More designs with traditional PCB “best practices” simply don’t apply. It’s not because they’re wrong, but because the problems we’re solving have fundamentally changed. In some cases, those best practices can actually limit performance. This is where PCB design moves beyond optimization and into something far more challenging: designing without a rulebook.
