Latest Patents

Juha Tolppa holds a patent for a "Method and apparatus for producing a hermetic vacuum joint at low temperature." This invention involves welding a first piece to a second piece using a laser beam. The first piece features an open cavity and a first sealing surface, while the second piece has a second sealing surface. The two pieces are placed inside a chamber with controllable internal pressure, which is adjusted to facilitate gas flow from the open cavity. The open cavity is then sealed by moving at least one of the pieces, forming a partially gas-tight preliminary joint. After the preliminary joint is established, the chamber is opened, and a welded seam is created by focusing a laser beam on the interface. The sealing surfaces of both pieces are designed to be substantially planar, ensuring a reliable joint.
