Method for assembly and airtight sealing of an encapsulation box

摘要

The method involves depositing a metal junction element on an upper face of a side wall (31), depositing an upper cap deposited above and in contact with a braze preform (40), and reducing temperature for inducing solidification of a material of the preform. A housing is placed in the side wall to receive a getter element (15). The preform and the cap are deposited for allowing co-operation of the getter element with the preform after placing the getter element, and the preform is positioned according to an operating mode. The upper cap is formed of French window (41), another braze preform (42) and a transparent window (43). An independent claim is also included for an infrared imaging device.
