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.
Cost Drivers
In this month’s issue of Design007 Magazine, our expert contributors explain the impact of cost drivers on PCB designs and the need to consider a design budget. They discuss the myriad design cycle cost adders—hidden and not so hidden—and ways to add value.

October Issue of Design007 Magazine: Partial HDI
October 8, 2024 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute
Partial HDI refers to the targeted use of HDI, usually on one section of one layer of the board. It offers designers an avenue for escape routing from BGAs with a pitch of .5 mm or less, when a mechanically drilled plated through-hole is impossible. With HDI relegated to one layer of the board, fabricators can avoid the expense of sequential lamination cycles.
In the October issue of Design007 Magazine, our expert contributors provide a complete, detailed view of partial HDI. Most experienced PCB designers can start using this approach right away. But you need to know these tips, tricks and techniques first.

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.

There are many types of printed circuit boards and multiple choices between the development of schematic and BOM to PCB technology selection, electronic PCB design, mechanical and physical properties, and PCB specification.
UHDI Fundamentals: UHDI Applications for Aerospace
08/13/2024 | Anaya Vardya, American Standard CircuitsUltra high density interconnect (UHDI) technology refers to advanced manufacturing processes used to create extremely compact and highly efficient electronic circuits at the sub-1-mil line and space level. In aerospace applications, UHDI is crucial due to the stringent requirements for weight, reliability, and performance in a challenging environment.
Happy’s Tech Talk #31: Novel Ultra HDI Architectures
08/12/2024 | Happy Holden -- Column: Happy’s Tech TalkUltra HDI has become the focus for many fabricators, especially as the follow-on for the 40-year-old conventional HDI. But there is more to UHDI than just finer traces and spaces. Novel architectures have been developed that complement the new dense lithography. One of the major advantages of HDI, and especially ultra HDI, is the miniature features of the process. Since the microvias and lands are so small, they can be swung around at various angles between the BGA lands. The angles and distances will depend on the BGA pitch and where the microvia is placed relative to the BGA SMT land.
