Andy Shaughnessy speaks with Jeremie Waller, senior electrical engineer at Quantel USA, about the panel he’ll be participating in during AltiumLive 2020 on design with manufacturing. He and panelists Gerry Partida of Summit Interconnect and Greg Zhiraldo of Advanced Assembly will discuss why designers need to see their fabrication and assembly providers as true partners, not just customers, and why communication is such a vital part of the design process.

‘The Trouble with Tribbles’

The original Star Trek series came into my life in 1966 as I was entering sixth grade. I was fascinated by the technology being used, such as communicators and phasers, and the crazy assortment of humans and aliens in each episode. My favorite episode is “The Trouble with Tribbles,” an episode combining cute Tribbles, science, and good/bad guys—sprinkled with sarcastic humor.
IPC-2581 Revision C: Complete Build Intent for Rigid-Flex

Ed Acheson, Cadence Design Systems
With the current design transfer formats, rigid-flex designers face a hand-off conundrum. You know the situation: My rigid-flex design is done so now it is time to get this built and into the product. Reviewing the documentation reveals that there are tables to define the different stackup definitions used in the design. The cross-references for the different zones to areas of the design are all there, I think. The last time a zone definition was missed, we caused a costly mistake.
Why We Simulate

Bill Hargin, Z-zero
When Bill Hargin was cutting his teeth in high-speed PCB design some 25 years ago, speeds were slow, layer counts were low, dielectric constants and loss tangents were high, design margins were wide, copper roughness didn’t matter, and glass-weave styles didn’t matter. Dielectrics were called “FR-4” and their properties didn’t matter much. A fast PCI bus operated at just 66 MHz. Times have certainly changed.
