Application of YAG Pulsed Laser Micro-Welding in MEMS Packaging
This paper reports a new packaging method for a wide range of MEMS for application on both the wafer and device scale. Titanium is used as the packaging material in this work and both silicon and titanium MEMS devices are integrated on to a titanium substrate. A Nd:YAG pulsed laser is used to micro-weld the titanium cap to the substrate. A three-dimensional time dependent model of heat flow dur...
متن کاملA flexible seam detection technique for robotic laser welding
This thesis deals with the problem of seam detection for robotic laser welding applications. Within the Mechanical Automation laboratory of the Engineering Technology faculty, a compact, lightweight and multi-purpose welding head is developed. The integrated welding head is attached to a robot and should be able to detect seams, learn trajectories, do the laser welding and inspect the welds. A ...
متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
متن کاملneodymium/YAG laser trabeculotomy
Laser trabeculotomies produced by directing a pulsed neodymium/YAG laser beam at specimens of human anterior chamber angle obtained post mortem or after enucleation were studied by light microscopy and by scanning and transmission electron microscopy to assess the dimensions of the openings created in the trabecular meshwork, their penetrance to the canal of Schlemm, and the extent or absence o...
متن کاملSubdermal Nd-YAG laser for axillary hyperhidrosis.
BACKGROUND Axillary hyperhidrosis is a common but difficult-to-treat condition with major social, labor, and emotional consequences. OBJECTIVE The aim of this study is to present the Nd-YAG laser as a safe and effective option for the treatment of axillary hyperhidrosis. MATERIALS AND METHODS From January 2002 to April 2007, 17 patients (15 women and 2 men) with axillary hyperhidrosis were ...
