Abstract

The invention discloses a vacuum packaging cover plate. The vacuum packaging cover plate comprises a main cover plate, wherein the main cover plate and a cavity form a sealed structure through welding; and a coating plate coated with a getter is arranged on the main cover plate, wherein multiple concave pits and / or bumps are arranged on the surface of the coating plate. The dimension of the vacuumpackaging cover plate can be reduced in a condition of the same coating area requirement, while the coating area can be enlarged in a condition of the same dimension of the vacuum packaging cover plate, so that the vacuum degree and service life of a device can be improved and prolonged, and the area utilization rate of a getter coating layer can be improved. The invention also provides a vacuumpackaging device with the abovementioned beneficial effects.

Description

technical field [0001] The present application relates to the field of vacuum packaging, in particular to a vacuum packaging cover plate and a vacuum packaging device. Background technique [0002] In small-volume vacuum packaging, in order to achieve and maintain the internal vacuum of the device, a Getter (getter) coating is usually coated on the inner surface of the cover plate or the inner surface of the cavity to absorb the outgas (escaped gas) generated inside the vacuum cavity. ), so that the device is maintained in a certain vacuum state, thereby ensuring the performance of the device and prolonging the life of the device. [0003] In the current design of vacuum packaged devices, the package size is generally compressed as much as possible to ensure the miniaturization of the volume under the same conditions. Capacity, must reserve enough coating area. In the prior art, increasing the thickness of the getter coating layer or increasing the size of the coating laye...
