Vladimir Kudriavtsev*, Rajeev Bajaj, Chris Lane, D¹
¹Yield Engineering Systems

Experts in the industry are seeing glass substrates as a promising alternative material for interposers, particularly for heterogeneous packaging such as 2.5D or 3D packages [1]. Recently, Intel revealed that they have developed one of the industry's first substrates specifically ... En savoir plus

Combustion Resistance of Fine Metal Parts

S. TOUZOUIRT¹, M. Dal², J. Daligault²
¹Air Liquide Campus Innovation Paris, Air Liquide, 1 Chem. de la Prte des Loges, 78350 Les Loges-en-Josas, France and PIMM Laboratory, Arts et Métiers Institute of Technology (Paris), CNRS, CNAM, HESAM University, 151 Boulevard de l’Hôpital, 75013 Paris, F
²PIMM Laboratory, Arts et Métiers Institute of Technology (Paris), CNRS, CNAM, HESAM University, 151 Boulevard de l’Hôpital, 75013 Paris, France

The presence of oxygen in metal installations can influence their flammability, which leads to frequent combustion ignitions. Various studies have been done to characterize this ignition, in order to classify metals according to their degree of flammability, and to minimize the risk of ... En savoir plus

A Study of Distributed Feed-Back Fiber Laser Sensor for Aeronautical Applications Using COMSOL Multiphysics

I. Lancranjan[1], C. Gavrila[2], S. Miclos[3], and D. Savastru[3]
[1]Advanced Study Centre - National Institute for Aerospace Research Elie Carafoli, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Romania
[3]National Institute R&D of Optoelectronics, INOE 2000, Bucharest, Romania

Distributed Feedback Fiber Laser (DFB-FL) sensors are increasingly used in aeronautical applications. One of the newest such applications consists in detecting the “transition” zone between laminar and turbulent air flow upon the extrados surface of an aircraft wing. In this specific ...

Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum

M. Bachmann[1], V. Avilov[1], A. Gumenyuk[1], M. Rethmeier[1]
[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the ... En savoir plus

A COMSOL Model of Damage Evolution Due to High Energy Laser Irradiation of Partially Absorptive Materials

P. Joyce[1], J. Radice[1], A. Tresansky[1], J. Watkins[1]
[1]United States Naval Academy, Annapolis, MD, USA

In this paper we present a transient numerical model of the heat transfer and thermochemical damage evolution in an IR translucent material using COMSOL Multiphysics. The model is evaluated using literature supplied and experimentally determined material properties for carbon black laden ... En savoir plus

Comparison Between Phase Field and ALE Methods to Model the Keyhole Digging During Spot Laser Welding

V. Bruyere[1], C. Touvrey[1], P. Namy[2]
[1]CEA-DAM, Is-sur-Tille, France
[2]SIMTEC, Grenoble, France

Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... En savoir plus

Heat Transfer and Phase Transformation on Matrix Assisted Pulsed Laser Evaporation (MAPLE) of Biocompatible Thin Layers

E. Lacatus[1], G.C. Alecu[1], M.A. Sopronyi[2], A. Tudor[1]
[1]POLITEHNICA University of Bucharest, Bucharest, Romania
[2]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and ... En savoir plus

[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany

The application of an oscillating magnetic field on the high-power full-penetration laser beam welding process of a 20 mm thick stainless steel plate was numerically and experimentally investigated. In the simulations, three-dimensional heat transfer and fluid dynamics as well as ... En savoir plus

Calculation in Coupling Coefficient of 1.3μm Quantum Dots Distributed Feed Back Laser with Half Etched Mesa Structure

Keishiro GOSHIMA et al.[1]

[1]Aichi Institute of Technology, Toyota, Aichi, Japan

Quantum Dots (QDs) laser is expected to have a low threshold current density and high thermal stability. We propose the QDs laser with the half-etched mesa distributed feedback (HEM DFB) structure. We accurately calculated the coupling coefficient in a HEM waveguide using the finite ... En savoir plus
