Thunderline-Z's state-of-the-art laser center offers high-power, industrial-grade laser services using a precise, controlled glove-box atmosphere for the laser hermetic sealing of high-frequency devices, components, and subassembly packages. Thunderline-Z can attach components within packages as well as seal lids to packages.

Thunderline-Z's laser welders precisely control the optical power applied to a package and a lid to form a consistent, repeatable seal, even for designs that incorporate posts or pedestals for stability. Thunderline-Z uses a combination of continuously variable laser power and pulse shaping to achieve secure welds between lids and package housings while working around critical circuit paths. In addition, with a lower-power laser hermetic sealing system, Thunderline-Z can perform reliable component placement of the most challenging hermetic-package components, including feedthrus and connectors.

Typical Specifications
Compared to conventional solder sealing or seam sealing approaches, Thunderline-Z's laser hermetic sealing forms a more robust, consistent metal-to-metal seal around the perimeter of a package. This maintains a higher level of hermeticity for the most demanding environments, including Class S (space-based) applications.
