Flexible Circuit Technology Workshop #6: Designs, Principles, and Practices
October 13, 2020 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute

In less than 30 minutes, learn from flex expert Joe Fjelstad about considerations when designing flexible circuits.
Fjelstad suggests starting holistically, considering all elements of the product:
- Use “paper doll” mock-ups to expose issues early on
- Be prepared to make decisions when mechanical and electrical requirements conflict
- Learn about tolerancing, nesting, etch factors, and more
Other segments include topics such as flexible circuit designs, principles, and practices; design guidelines for bending, folding, and dynamic movement of flexible circuits; flexible circuit singulation methods; assembly aids, and more.
These 10 workshop segments, created and presented by renowned flex expert Joe Fjelstad, produced and edited by I-Connect007, and sponsored by American Standard Circuits, are a comprehensive look at flexible circuit board design, manufacturing, and assembly.
Register here to view this segment and the entire free workshop. Don’t miss what technical editor Pete Starkey calls, “An encyclopaedic series!”

Facing the Future: Time for Real Talk, Early and Often, Between Design and Fabrication
07/08/2025 | Prashant Patel -- Column: Facing the FutureThere has always been a subtle but significant divide between those who design and those who build printed circuit boards. It’s not a hostile gap, but it is a real one, and in today’s high-speed, high-complexity, high-stakes environment, that gap is costing us more than time and yield. It’s costing us innovation.
DownStream Acquisition Fits Siemens’ ‘Left-Shift’ Model
06/26/2025 | Andy Shaughnessy, I-Connect007I recently spoke to DownStream Technologies founder Joe Clark about the company’s acquisition by Siemens. We were later joined by A.J. Incorvaia, Siemens’ senior VP of electronic board systems. Joe discussed how he, Rick Almeida, and Ken Tepper launched the company in the months after 9/11 and how the acquisition came about. A.J. provides some background on the acquisition and explains why the companies’ tools are complementary.
Elementary Mr. Watson: Retro Routers vs. Modern Boards—The Silent Struggle on Your Screen
06/26/2025 | John Watson -- Column: Elementary, Mr. WatsonThere's a story about a young woman preparing a holiday ham. Before putting it in the pan, she cuts off the ends. When asked why, she shrugs and says, "That's how my mom always did it." She asks her mother, who gives the same answer. Eventually, the question reaches Grandma, who laughs and says, "Oh, I only cut the ends off because my pan was too small." This story is a powerful analogy for how many PCB designers approach routing today.
Connect the Dots: The Future of PCB Design and Manufacturing
07/02/2025 | Matt Stevenson -- Column: Connect the DotsFor some time, I have been discussing the increasing complexity of PCBs and how designers can address the constantly evolving design requirements associated with them. My book, "The Printed Circuit Designer’s Guide to… Designing for Reality," details best practices for creating manufacturable boards in a modern production environment.
