Tungsten Copper Sealing Weld Picture
The sealing process is generally used for soldering packaged devices, optical devices, sensor devices, and MEMS devices that require high sealing. It is generally carried out under a nitrogen or vacuum atmosphere, and the tungsten copper sealing weld can ensure airtightness better.
