High Density Through Glass Vias for Advanced Chip Packaging
By Ralph Delmdahl, Rainer Pätzel, Rolf Senczuk and Jan Brune Glass is a promising material from which advanced interposers for high density electrical interconnects for 2.5D and 3D chip packaging can be produced. The supply of ultra-thin glass wafers with thicknesses of 100 µm and below shows attractive cost and superior high frequency performance relative […]
LIA’s Medical LSO Courses To Feature Laser Demonstrations
ORLANDO, FL, Aug. 14, 2014 — In an effort to give students a first-hand experience with lasers in the operating room, the Laser Institute of America (LIA) is partnering with medical solutions provider Universal Hospital Services (UHS), through its UHS Surgical Services business unit, to offer laser demonstrations at LIA’s Medical Laser Safety Officer (MLSO) training […]
Laser Micro Welding of Aluminum with the Superposition of a Pulsed Diode Laser and a Pulsed Nd:Yag Laser
By Philipp von Witzendorff, Lorenz Gehrmann, Martin Bielenin, Jean-Pierre Bergmann, Stefan Kaierle and Ludger Overmeyer Pulsed laser welding is applied for welding of thin aluminum sheets when the heat affected zone has to be minimized. The pulsed laser process enables a low and precise heat input because the heat dissipates away in between the laser pulses. […]
Embedding Fiber Optic Sensors Using Laser Additive Manufacturing
By Dirk Havermann, William N. Macpherson, Robert R. J. Maier and Duncan P. Hand Laser Additive Manufacturing provides novel and exciting possibilities when constructing 3-dimensional free form components in polymers and metals. The process of building 3D components from the inside-out opens up the possibility of embedding sensors into the heart of a component. Fiber […]
