Laser Seam Sealing of Optoelectronic Packages
Keywords: Laser Welding, Seam Sealing, Design for manufacturing
The use of laser welding as a joining process for seam sealing of optoelectronic and electronic packages offers some unique advantages over existing resistance or epoxy based techniques. To implement or migrate to laser welding as a highly reliable seam sealing process certain key selections and design features are needed that encompass the laser, materials, platings, part geometry and part tolerances. An overview of the key features of laser welding and details of package design rules is provided.
