Connect the Dots: Evolution of PCB Manufacturing—Lamination

10/02/2025 | Matt Stevenson -- Column: Connect the Dots
When I wrote The Printed Circuit Designer's Guide to...™ Designing for Reality, it was not a one-and-done effort. Technology is advancing rapidly. Designing for the reality of PCB manufacturing will continue to evolve. That’s why I encourage designers to stay on top of the tools and processes used during production, to ensure their designs capitalize on the capabilities of their manufacturing partner.

Driving Innovation: Mastering Panel Warpage

09/23/2025 | Simon Khesin -- Column: Driving Innovation
During the complex and multi-step process of PCB fabrication, a panel's flatness is constantly at risk. A host of factors can introduce warpage, bending, and unevenness, presenting a fundamental challenge to achieving high-precision results. This deformation (sometimes referred to as “bow and twist”), even on a microscopic scale, can lead to critical defects during subsequent stages, such as component surface mounting (e.g., tombstoning, solder opens) and the PCB's long-term functional reliability.

Beyond Design: Slaying Signal Integrity Villains

09/17/2025 | Barry Olney -- Column: Beyond Design
High-speed PCB design is a balancing act, where subtle oversights can develop into major signal integrity nightmares. Some culprits lie dormant during early validation, only to reveal themselves later through workflow disruptions and elusive performance bottlenecks. Take crosstalk, for example. What begins as a stray signal coupling between traces can ripple through the design, ultimately destabilizing the power distribution network. Each of these troublemakers operates with signature tactics, but they also have well-known vulnerabilities.

Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs

09/08/2025 | Kurt Palmer -- Column: Driving Innovation
In PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.

Global PCB Connections: Understanding the General Fabrication Process—A Designer’s Hidden Advantage

08/14/2025 | Markus Voeltz -- Column: Global PCB Connections
Designers don’t need to become fabricators, but understanding the basics of PCB fabrication can save you time, money, and frustration. The more you understand what’s happening on the shop floor, the better you’ll be able to prevent downstream issues. As you move into more advanced designs like HDI, flex circuits, stacked vias, and embedded components, this foundational knowledge becomes even more critical. Remember: the fabricator is your partner.
