Presentation
The chair « Printed Circuit Boards » aims to analyze the mechanical behavior of PBC under severe environment. It is located at LEM3 laboratory ( Laboratory of Microstructure Studies and Mechanics of Materials, Université de Lorraine, CNRS, Arts et Métiers). Funded by three french SMEs operating in the manufacturing of PCB : CIMULEC, CSI-SUD OUEST, SYSTRONIC, the chair is also supported by the local authorities: Eurométropole de Metz, Département de la Moselle and Région Grand-Est.
The PCB, core of any modern device
Any industrial product is now equipped with electronic devices, making it smart, interactive and connected to its environment. A key element of the electronic system is the printed circuit board, carrier of chips, which also ensures the interconnection between all passive and active components.
The first aim of the PCB industrial chair is to propose a better understanding of damage mechanisms at the origin of the loss of reliability of printed circuit boards under severe environments. The scientific challenges which currently hamper the deployment of the latest technologies in standard equipment are at the heart of the research carried out within the chair.
A second goal of the chair is to support microelectronic industrial sector for aeronautics, space and military applications by providing fondamental researches. This need is crucial because the European printed circuit industry suffers from competitiveness from emerging countries. However, European independence must be maintained. The ever-faster development of breakthrough technologies in design no longer allows SMEs to accumulate enough experience. It is therefore necessary to intensify research on printed circuit boards.
The team
The chair benefits from skills of many LEM3 researchers. LEM3, UMR CNRS 7239 (Laboratory of Microstructure Studies and Mechanics of Materials, www.lem3.univ-lorraine.fr. It is made up of more than 300 people, including around 100 permanent staff, divided into 8 research teams. Its research activities focus on the mechanics of materials, with both experimental, numerical and theoretical researches. Its area of expertise has long been focused on metallic materials. For the past ten years, the fields of application of research conducted at LEM3 have been extended to composite materials and the effect of operating conditions on the behavior of materials. In addition, the laboratory is a partner of the Grand Est region to support industrial companies and wishes to boost the sectors of excellence and of the future The chair is a continuation of many projects initiated since 2007 on this theme. It is stepping up an R&D strategy already present within the “LEMCI” LabCom, funded by the ANR from 2015 to 2018, https://labcom-lemci.univ-lorraine.fr/ The members who are more particularly active within the chair are:Gautier Girard, researcher funded by the chair Marion Martiny, Professor at the Université de Lorraine (LEM3, UFR MIM) Sébastien Mercier, Professor at the Université de Lorraine (LEM3, UFR MIM)
