From IPC Standards to Practical DFM

10/21/2026 | Marcy LaRont, I-Connect007
DFM seems like common sense: If we know the rules a PCB must meet, why not check the design against them before it ever reaches the factory? In practice, of course, it’s not quite that simple. I caught up with Susan Kayesar, product manager at Siemens and longtime contributor to Global Electronics Association standards activities, to talk about an ongoing effort between Siemens and the Association to translate IPC requirements into practical, software-based DFM checks.

Flexible Thinking: Beyond DFM—PCB Design and Manufacturing as a Cooperative Effort

09/01/2026 | Joe Fjelstad -- Column: Flexible Thinking
The concept of co-designing PCBs by incorporating input from all areas of manufacturing has grown significantly over the past several years, bringing a sharper focus on the early contributors to a collaborative electronic system. From those pioneers, we have learned that the PCB is no longer simply the platform on which a design is manifested; it is now an active part of the electrical, thermal, mechanical, and economic architecture of the product. As operating frequencies rise, component pitches shrink, power densities increase, and product schedules tighten, decisions made by one discipline can no longer be isolated from the consequences they create for others.

Happy’s Tech Talk #48: Digital Twins—Integrating Design and Manufacturing

06/02/2026 | Happy Holden -- Column: Happy’s Tech Talk
New product realization and design for manufacturing and assembly (DFM/A) are becoming increasingly visible as programs that can improve time-to-market and reduce product costs. These simulations of real-time manufacturing are now referred to as digital twins. While many companies are developing such programs, a unifying framework is needed to coordinate their application.

Elementary, Mr. Watson DFX—Basically a Basket of Crabs With Spreadsheets

04/22/2026 | John Watson -- Column: Elementary, Mr. Watson
One of the joys of living in San Diego is that I'm never far from the ocean. Aside from burying my toes in the sand at the beach, I particularly enjoy going down where the fishing boats come in. I once watched a fisherman standing beside several baskets of crabs. Most had lids tied on, but one was completely open. Curious, I asked why he wasn't worried about them escaping. It reminded me of a well-known story.

Target Condition: When Design Outpaces Manufacturing

04/23/2026 | Kelly Dack -- Column: Target Condition
Most PCB designers already understand why design for manufacturing (DFM) matters. If a product can’t be built reliably, repeatedly, and at a price anyone will actually pay, it’s dead on arrival. You may have the most elegant schematic and layout ever drawn in a CAD tool, but if the PCB suppliers can’t make it, or the EMS sources refuse to quote it, you may well be considered more of a Nutty Professor or well-meaning inventor than a PCB designer.
