A new platform for streamlining procurement takes shape. 

Supply chain has been the story of the past year, and a new face to the industry proposes to help resolve that by connecting electronics engineers with printed circuit board assemblers.

Vincent Bedát is a mechanical engineer and recent MBA graduate of the MIT Sloan School of Management. He is also founder of a San Francisco-based startup called Volthub. I came across Volthub as part of an announcement of the finalists for the MIT $100K Entrepreneurship Competition. That program has various aspects to it, but in short it’s a way to match early-stage teams with industry experts and entrepreneurs, and perhaps gain some seed money along the way. Some of the companies that have been part of the competition over the years include HubSpot and Akamai Technologies.

Bedát hails from Zurich, Switzerland, where he also studied, graduating with a master’s in mechanical engineering from ETH Zurich. He then went on to work at the robotics startup Synapticon in Stuttgart, Germany, as a mechanical engineer and eventually project manager.

A new study reveals emerging applications for attaching very-fine-pitch parts using low-temp methods.

Electrically conductive adhesives (ECAs) have been touted for decades as a potential replacement for solder. Technology roadmaps by organizations ranging from IPC to the Surface Mount Council often listed ECAs as a “coming” technology, and scores of papers have been presented highlighting possible uses and likely end-products.

In early October, the international research firm IDTechEx released a new study called “Electrically Conductive Adhesives 2022-2032: Technologies, Markets, and Forecasts.” Matthew Dyson, Ph.D., a senior technology analyst at IDTechEx specializing in printed, organic and flexible electronics, spoke with Mike Buetow about the study’s findings.

IBM announces 2nm GAA-FET technology. IBM announced its 2-nanometer CMOS technology, developed at its Albany research center. The development has technical firsts: the use of bulk Si wafers with bottom dielectric isolation under the nanosheet stack; reducing leakage and enabling 12-nnm gate lengths; a second-generation inner spacer dry process for precise gate control; FEOL EUV patterning to allow nanosheet widths from 15 to 70nm; and a novel multi-Vt scheme. This technology is expected to give a 45% performance boost or 75% power reduction, compared with the 7nm. (IEEC file #12324, Semiconductor Digest, 6/11/21)

Light-based method creates 2-D polymer. Linköping University researchers developed a method that uses light to manufacture 2-D polymers that have the thickness of a single molecule and could create a path for the development of ultra-thin, functional 2-D materials with highly defined crystalline structures. Using an on-surface photo-polymerization process, they tested a way to manufacture a 0.5nm-thick, 2-D polymer consisting of several hundred thousand molecules identically linked. The two-step method takes advantage of the self-organizing properties of fluorinated anthracene triptycene molecules. Because the polymerization takes place in a vacuum, the material is protected from contamination. The 2-D polymer film is stable under atmospheric conditions. (IEEC file #12370, Photonics Spectra, 7/14/21)

A decade in, IPC-2581 Consortium members say the pursuit toward widespread adoption of the vendor-neutral standard was well worth the rigorous effort.

Few engineers working in electronics manufacturing today predate the first efforts to develop and implement an industry-wide standard for intelligent electronics data transfer.

As early CAD tools were introduced in the late 1960s and early 1970s, IPC launched a vendor-neutral effort to describe electronics design data from schematic through test.
