DuPont, Taconic and PFC Team Up For High-Speed Flex

Kelly: The flex circuit side is pretty strong. We are a North American fabricator, and we’ve almost doubled in the last five years.
Matties: That's great. How many employees do you have?
Kelly: We have 110. We’ve just seen more and more business. Eventually, the high-volume stuff will go offshore, it always does, but the specialty stuff, the high-volume, low-mix, it's always going to be here. The new stuff is going to be here and then it migrates. Packaging is everything. They need everything smaller and smaller, lighter and lighter. If you look inside the Apple watch, there are 10 flex circuits. There are no rigid boards.
Matties: There's not even room for 10 circuits in there!
Oliver: We want them big!
Matties: So much easier to deal with our aging eyesight!
Kelly: It costs me more to count them than it does to build one. The iPhone6 has, I think, six or seven, for example. And 10 GHz is becoming very over the hill and now everybody is moving into 18, 28, 100 GHz. We've even had phone calls asking, "How do I build a 100 GHz flex?" I say, “Well, I might be able to build it but how are you going to test it?”
Oliver: There's a lot of flex in test equipment. That's a very important market for Steve. It's a testament that you can use high-frequency in flex because a lot of test equipment uses flex in the probes and then in various other aspects of testing.
Kelly: This stuff starts up there at the test guys and eventually migrates down, just like anything else in this world. Then it becomes mainstream and this is on the cusp of that, and it will start developing.
Matties: This is great. It's nice to see that the edge is being pushed out further and further. Good for you guys. Congratulations on your paper, too.
Oliver: Thank you for the interview. We appreciate it.

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.
