Current IssueAdvanced Packaging and Stackup Design
This month, our expert contributors discuss the impact of advanced packaging on stackup design—from SI and DFM challenges through the variety of material tradeoffs that designers must contend with in HDI and UHDI.
Rules 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.

Words of Advice: Fabricator Feedback?
January 17, 2019 | Andy Shaughnessy, Design007 MagazineEstimated reading time: Less than a minute
In a recent Design007 Survey, we asked the following question: What is the most important feedback that you receive after your board is manufactured? Here are just a few of the answers, edited slightly for clarity.
Karl Bates, ConnectPCB: Clearance is less than I expect, copper balance, and thieving.
Chand Basha M, Anora Semiconductor: We could not plate the board to required plating thickness. We had to reduce few pad sizes to adjust the fabrication process. A few mechanicals in the design are altered slightly due to capability issues.
Jim Pierce, Axiom Electronics: Impedance specifications, testing results, and documentation.

Growth Unfolds: The First of STARTEAM’s Trio of Factories Set to Expand
12/05/2024 | STARTEAM GLOBALSTARTEAM is thrilled to share news of our upcoming 3-step expansion at JST, with each step adding 50,000m² per month which began on May 27, 2024. This carefully planned extension is designed to significantly increase our production capacity and expand our talented team. Currently, our production space covers 30,000m². Through this expansion, we are setting our sights on incrementally increasing our capacity from 70,000m²/month to a remarkable 130,000m²/month.
Connect the Dots: Designing for Reality: Strip-Etch-Strip
12/05/2024 | Matt Stevenson -- Column: Connect the DotsIn the previous episode of I-Connect007’s On the Line with… podcast, we focused on pattern plating. At this point, we are close to completing our boards and ready for the strip-etch-strip (SES) process. By this stage of the manufacturing process, we have laminated all the internal layers together, drilled the through-holes, applied the image to the external layers through photoresist, plated the copper in those channels to beef up the copper thickness for traces, pads, and through-holes, added a layer of electrolytic tin over the top of that copper to protect it during subsequent stages of production.
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.
