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.

Cadence DesignTrue DFM Ecosystem Connects Manufacturers with Customers
September 4, 2018 | Cadence Design Systems, Inc.Estimated reading time: 2 minutes
Cadence Design Systems, Inc. has launched a broad ecosystem with nine initial printed circuit board (PCB) manufacturing partners to enable customers to easily get the partners’ technology files they need to ensure PCB design manufacturability early in the design process. This reduces rework, shortens design cycles, and accelerates new product introduction. Customers have received savings from half to two-thirds fewer technical queries (TQs) from manufacturers when they’ve used the Cadence DesignTrue DFM (design for manufacturability) technology due to using tailor-made spacing, annular ring, copper features and mask rules to assure they are designing the board correctly the first time.
Cadence DesignTrue DFM functionality flags manufacturing rule violations in real time during the PCB layout process with both the Allegro and OrCAD design tools. All other PCB design tools demand designers wait until the design is complete to do DFM signoff on manufacturing outputs, which often requires significant rework and schedule delays.
Nine PCB manufacturers have already become Cadence DesignTrue partners, allowing them to distribute their manufacturing rules to Cadence customers. These include Bay Area Circuits, CircuitHub, Mass Design, Multek, OSH Park, Rocket EMS, Sierra Circuits, Tempo Automation and Würth Elektronik.
“Our goal is to improve PCB designer productivity, and this large ecosystem and new web portals allow our customers to significantly shorten their design cycles with the industry’s first real-time in-design DFM checking,” said Steve Durrill, senior product engineering group director at Cadence. “Instead of manually adding the rules to their PCB design environment, now they can quickly download the appropriate file and update as required.”
By creating new web portals, Cadence is ensuring that customers can access the latest DFM rules from the PCB manufacturers at the start of their design process. Customers can view participating manufacturers and request DesignTrue DFM technology files directly, eliminating the lengthy and error-prone manual entry of hundreds of rules. DFM rules are checked in real time as part of the PCB layout process, reducing the amount of DFM errors found in the manufacturing output. These checks prevent crucial manufacturing errors and limit iterations required to fix such errors. Partners can use the vendor portal to easily distribute rules that match their post-process DFM checks. Cadence users can take advantage of the customer portal to request and receive the rules they need from the manufacturers.
“The Cadence DesignTrue DFM partner program allows us to easily share our PCB manufacturing rules to Cadence customers,” said Dana Korf, senior director Central Manufacturing Engineering and NPI, Multek. “This ensures our customers are designing to our most up-to-date manufacturing constraints, greatly reducing the number of iterations to address DFM errors that we normally see in the PCB signoff process. This will help our customers get their designs done faster, accelerating new product introduction.”

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.
