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.

Freedom CAD offers Power Integrity Analysis
July 13, 2015 | Freedom CADEstimated reading time: 1 minute
As supply voltages continue to decrease and power consumption increases, impedance of power delivery networks at DC and over frequency has become a critical consideration for any electronic package or PCB design.
Using simulation to identify potential power integrity problems such as DC voltage drop and frequency response is essential for today’s high-speed digital designs. By using Ansys’ SIwave software, Freedom CAD Services has the ability to perform pre-layout power integrity analysis and reduce post–layout power delivery problems. This includes optimization of copper weights, bulk storage and bypass capacitor selection.
“We are pleased to be able to offer PCB engineering and layout solutions to our customers that can include Power Integrity and Voltage Drop analysis.” says Don Duncan, Chief Technology Officer at Freedom CAD Services. “It’s becoming increasingly important to understand and predict the potential impact of power integrity and voltage drop in the sensitive electronic products that we frequently design. I only see this importance growing as the design complexities grow across our projects from wearable devices to terabyte computers.”

Fresh PCB Concepts: PCB Design Essentials for Electric Vehicle Charging
11/27/2024 | Team NCAB -- Column: Fresh PCB ConceptsElectric vehicles (EVs), powered by electricity rather than fossil fuels, are transforming transportation and reducing environmental impacts. But what good is an EV if it can't be easily charged? In this month's column, Ramon Roche dives into the role of printed circuit boards (PCBs) in electric vehicle charging (EVC)—and the design considerations.
Unlocking Advanced Circuitry Through Liquid Metal Ink
10/31/2024 | I-Connect007 Editorial TeamPCB UHDI technologist John Johnson of American Standard Circuits discusses the evolving landscape of electronics manufacturing and the critical role of innovation, specifically liquid metal ink technology, as an alternate process to traditional metallization in PCB fabrication to achieve ever finer features and tighter tolerances. The discussion highlights the benefits of reliability, efficiency, and yields as a tradeoff to any increased cost to run the process. As this technology becomes better understood and accepted, even sought out by customers and designers, John says there is a move toward mainstream incorporation.
Fresh PCB Concepts: The Critical Nature of Copper Thickness on PCBs
10/31/2024 | Team NCAB -- Column: Fresh PCB ConceptsPCBs are the backbone of modern electronics and the copper layers within these boards serve as the primary pathways for electrical signals. When designing and manufacturing PCBs, copper thickness is one of the most critical factors and significantly affects the board’s performance and durability. The IPC-6012F specification, the industry standard for the performance and qualification of rigid PCBs, sets clear guidelines on copper thickness to ensure reliability in different environments and applications.
Book Excerpt: The Printed Circuit Designer’s Guide to... DFM Essentials, Ch. 1
10/25/2024 | I-Connect007The guidelines offered in this book are based on both ASC recommendations and IPC standards with the understanding that some may require adjustment based on the material set, fabricator processes, and other design constraints. This chapter details high-frequency materials, copper foil types, metal core PCBs, and the benefits of embedded capacitance and resistor materials in multilayer PCBs.
The Cost-Benefit Analysis of Direct Metallization
10/21/2024 | Carmichael Gugliotti, MacDermid AlphaCarmichael Gugliotti of MacDermid Alpha discusses the innovative realm of direct metallization technology, its numerous applications, and significant advantages over traditional processes. Carmichael offers an in-depth look at how direct metallization, through developments such as Blackhole and Shadow, is revolutionizing PCB manufacturing by enhancing efficiency, sustainability, and cost-effectiveness. From its origins in the 1980s to its application in cutting-edge, high-density interconnects and its pivotal role in sustainability, this discussion sheds light on how direct metallization shapes the future of PCB manufacturing across various industries, including automotive, consumer electronics, and beyond.
