iNEMI Roadmap: Co-Chairs Seeking Contributors

We are pleased to announce that co-chairs have been appointed for three priority-wave topics in the refreshed iNEMI Roadmap:

PCB: Tarja Rapala (Technology Director, EIPC) and Joe Beers (Vice President of Sales, Gold Circuit Electronics) 

Board Assembly: Jasbir Bath (Owner, Bath Technical Consultancy) and Dr. Paul Wang (Vice President, Mitac International)

Sustainable Electronics: Pia Tanskanen (Head of Environment, Nokia) and Prof. Carol Handwerker (Professor of Materials Engineering, University of Purdue)

 Upcoming Events

iNEMI Presentation at IWCS Cable & Connectivity Industry Forum (October 12; Providence, Rhode Island) — Tatiana Berdinskikh (Senko Advanced Components) will present “Development of Best Practices and Guidelines for the Use of Expanded Beam Connectors in Data Center Applications,” in Session 3: Advances in Optical Connectivity (8:00-11:55 a.m., Room 554). The presentation is based on results from iNEMI’s Best Practices for Expanded Beam Connectors in Data Centers project. See the article below about the end-of-project webinar scheduled for this project on November 10 and 11.

iNEMI Roadmap Workshop at InterPACK (October 25; Garden Grove, California) — An iNEMI Roadmap workshop session is scheduled on Tuesday, October 25, 10:15-11:45 a.m, at ASME’s International Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Microsystems (InterPACK). The focus of the workshop will be on market and technology drivers for advanced packaging. iNEMI’s Director of Roadmapping Francis Mullany, along with CEO Shekhar Chandrashekhar, are session facilitators. Francis will also be participating in Panel 8: Heterogeneous Integration Roadmapping later that day (4:00-5:30 p.m.). Panel participants will discuss various roadmapping efforts for heterogeneous integration and how they can complement each other to strengthen and unify direction in the industry. 

iNEMI Presentation at IMPACT 2022 (October 27; Taipei, Taiwan) — “The Effects of Voids on Solder Joint Reliability in First Level Interconnect,” will be presented by Sze Pei Lim (Indium), representing iNEMI’s 1st Level Interconnect Void Characterization project at the International Microsystems, Packaging, Assembly and Circuits Technology (IMPACT) conference. The presentation is part of session S12: Advanced Bonding and Interconnect Technology on October 27. iNEMI is a co-organizer of this event which will be held at the Taipei Nangang Exhibition Center, Taipei, Taiwan.

End-of-Project Webinar: Extended Reliability Assessment for Electronic Components (October 27 & 28) — Phase 1 of the Extended Reliability Assessment for Electronic Components project identified component-level parts that would be the most valuable to a range of users in the electronics industry. In addition, the team identified several possible testing scenarios based on potential use conditions and began identifying ways to conduct testing for extended reliability. This project report-out will review the findings and recommendations of the team as well as identify next steps for Phase 2. For additional information, contact Mark Schaffer (marks@inemi.org)

iNEMI Survey Report: Use of AOI to Inspect Fine Pitch Circuit Patterns (October 27/28)  — Phase 4 of the iNEMI Panel Level Package Fine Pitch Circuit Inspection/Metrology project conducted a survey to evaluate and assess the limits of automated optical inspection (AOI) equipment for inspection of fine pitch circuit patterns on advanced substrates in wafer or panel form. This survey specifically focused on inspection capabilities for substrate circuit patterns with line spaces 10um and finer. Join us for this webinar that will report results from the survey and introduce next steps for the project. The project team plans to design test vehicles (TVs) based on survey feedback about critical defect types and mode detection and use the TVs to study AOI equipment/system capabilities, including circuit pattern quality checks by defect levels and impedance.
