Seam Sealing of Electronic Packages Using Pulsed Laser Sources
ensure safe and reliable operation, the components’ housing must be sealed hermetically. Using a laser source as a tool provides high welding speeds and produces fine welding seams with narrow welding radiuses [...] thermally or mechanically. For example, to create the welding seam, the package to be welded is moved under a pulsed laser source causing the laser spots to overlap each other. This is ideal when the welding process [...] process is relatively simple, and the laser spot size is proportionate to the welding width. For a consistently high welding quality, the size and spacing of the laser pulse overlap must remain constant;
