Current IssueRules of Thumb
This month, we delve into rules of thumb—which ones work, which ones should be avoided. Rules of thumb are everywhere, but there may be hundreds of rules of thumb for PCB design. How do we separate the wheat from the chaff, so to speak?
Partial HDI
Our expert contributors provide a complete, detailed view of partial HDI this month. Most experienced PCB designers can start using this approach right away, but you need to know these tips, tricks and techniques first.
Silicon to Systems: From Soup to Nuts
This month, we asked our expert contributors to weigh in on silicon to systems—what it means to PCB designers and design engineers, EDA companies, and the rest of the PCB supply chain... from soup to nuts.

September Design007 Magazine: Silicon to Systems
September 9, 2024 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute
Silicon to Systems: From Soup to Nuts
Traditionally, most designers of PCBs and ICs have operated in separate silos, unaware of much of what is happening just upstream or downstream. IC designers did their thing and PCB designers did theirs, and everything worked—until recently, that is.
Now, the increase in complexity in electronics is driving technologists throughout the electronics supply chain to adopt a “silicon to systems” outlook. Advanced packaging systems are causing PCB designers problems with signal integrity, power delivery requirements, and thermal issues.
This month, in the September 2024 issue of Design007 Magazine, we asked our expert contributors to weigh in on silicon to systems—what it means to PCB designers and design engineers, EDA companies, and the rest of the PCB supply chain—from soup to nuts.

Rules of Thumb: A Primer
11/14/2024 | Andy Shaughnessy, Design007 MagazineMany industry-wide rules of thumb are based on DFM constraints or formulas, but others are based on tribal knowledge. In this interview, Andy Shaughnessy sits down with our contributors Kris Moyer and Kelly Dack to discuss the role of rules of thumb, when to employ them, and when it’s time to do the math.
Elementary, Mr. Watson A Designer's Dilemma—Metric or Imperial Units?
11/07/2024 | John Watson -- Column: Elementary, Mr. WatsonIn the early 1800s, as trains began to spread across the United States, different companies built their tracks in ways that made sense to them. They chose their track widths (gauges) with no set standard. Some tracks were about four feet wide, with others at five or even six feet. Each company thought their choice was best, but this led to a big problem: Trains from one track couldn't run on another if the gauges didn't match. Often, trains had to stop at the state line for all their goods and passengers to switch trains, which cost extra time and money.
One Partial HDI Technique: mSAP
11/05/2024 | Andy Shaughnessy, Design007 MagazineChris Hunrath, vice president of technology at Insulectro, believes that mSAP just might be the trick for designers considering partial HDI. As Chris explains, the materials and equipment required for the mSAP process are easily available, and the process is well established. This could be a great option for designers working with BGAs that have a pitch of 0.5 mm or less.
Global PCB Connections: Mission Critical—Communication Between PCB Designers and Fabricators
10/24/2024 | Jerome Larez -- Column: Global PCB ConnectionsIn my first column, I want to discuss the critical importance of communications between the PCB design and the PCB fabrication engineer. I’ll explore why clear communication is so important, highlight the differences between standard and CTQ items, and outline the key issues that must be agreed upon to achieve success in PCB manufacturing.
The Shaughnessy Report: Are You Partial to Partial HDI?
10/08/2024 | Andy Shaughnessy -- Column: The Shaughnessy ReportSometimes, a little technology is all you need. Star Trek’s Borg character only needs a funky eyepiece contraption to access all The Collective’s data, like an outer space Wi-Fi. Like the Borg’s eyepiece, we may only need a little bit of HDI in one corner of the board. We might only need partial HDI.
