January 12, 2021

Eric Fossum is best known for the invention of the CMOS image sensor better known as the “camera-on-a-chip” used in billions of cameras, from smart phones to web cameras to ingestible pill cameras to DSLRs.

In 2017, Eric was a co-recipient of the Queen Elizabeth Prize for Engineering, the world's top engineering prize (and considered by many as equivalent to the Nobel Prize) for the invention of digital imaging sensors.

Eric was inducted into the National Inventors Hall of Fame and is member of the National Academy of Engineering. He is a solid-state image sensor device physicist and engineer, and his career has included academic and government research, and entrepreneurial leadership of several startups. He is the John H. Krehbiel Sr. Professor of Emerging Technologies at the Thayer School of Engineering at Dartmouth college. Eric also serves as Associate Provost of Dartmouth College for Entrepreneurship and Technology Transfer, and directs Dartmouth's PhD Innovation Programs.

Eric recently co-founded another startup with his former students, Gigajot Technology, Inc.

PCB Chat 71: Is the US Ready for Smart Manufacturing?

December 31, 2020

Smart manufacturing, generally defined as the use of fully integrated, collaborative manufacturing systems that respond in real time to meet changing demands and conditions in the smart factory, in the supply network, and in customer needs, is quickly becoming reality. Is the US ready, or has it already been beaten by offshore companies? Mike Buetow considers the possibilities.

PCB Chat 70: Kent Balius on Front-End Engineering

PCB Chat 70: Kent Balius on Front-End Engineering

December 27, 2020

Kent Balius has been at the forefront of front-end engineering for 30 years at some of the world's largest PCB fabricators.

He spent the past 20 years at TTM / Viasystems, where he managed software applications and automation solutions for North America and Asia-Pacific operations.

He just launched EPIC Front-End Engineering, which provides consultation, project management, software applications and development support to the PCB manufacturers, with the objectives of driving advanced automation to achieve productivity, improved quality, reduced labor costs.

He speaks about how the automation of design-to-fabrication the affects Industry 4.0 implementation with PCB Chat's Mike Buetow.

RM 57: A Conversation with CAF Expert Graham Naisbitt

RM 57: A Conversation with CAF Expert Graham Naisbitt

December 11, 2020

Conductive anodic filament (CAF) is a form of electrochemical migration (ECM). Unlike surface-level ECM, CAF exists beneath the surface of the circuit assembly. Graham and Mike Konrad discuss the causes of CAF and methods to test for and mitigate CAF.

Graham has an extensive history working in the electrical and electronic manufacturing industry. Graham was the IEC 1906 Lord Kelvin Award Winner. IEC TC91 WG2, 3 and 10 Maintenance Leader of 4 Standards. He is vice chair of the IPC 5-30 Cleaning and Coating Sub-Committee overseeing 15 IPC Standards Development Committees. He has received 14 IPC Standards Awards and is a BSI British Standards Institution (EPL501) Member.

Graham is a Specialist in Insulation Resistance Testing, Ionic Contamination Control, Solderability, Conformal Coating materials and application systems, including Cleaning, Inspection and Test.

PCB Chat Episode 68: The IPC-2581 Consortium on Electronics Data Transfer

PCB Chat Episode 68: The IPC-2581 Consortium on Electronics Data Transfer

November 6, 2020

IPC-2581 is a standard format for describing and transferring printed circuit board design and assembly manufacturing data from the OEM to fab and assembly. It is an open format developed by industry consensus through the auspices of IPC, and it is vendor-neutral.

IPC-2581 is being rebranded as IPC-DPMX, which stands for Digital Product Model Exchange.

On this episode of PCB Chat, host Mike Buetow is joined by IPC-2581 Consortium chair Hemant Shah, DfM expert Dana Korf, Cisco technical leader of electrical engineering Terry Hoffman, and IPC manager of design standards Patrick Crawford. They discuss the latest revision to IPC-2581, which is set to be released in November.
