Abstract
A sealing-object () is fixed to a base-object (). The sealing-object comprises a through-hole (). The objects are fixed to each other in the following manner. In a preparation step, a fixing layer () is provided between the base-object and the sealing-object. In addition an evacuation device () equipped with an evacuation channel () is placed onto the sealing-object. The through-hole of the sealing object has a first extremity opening out on the evacuation channel and a second extremity opening out on the fixing layer. In a fixing step, the fixing layer is heated which causes the fixing layer to release gas. The gas is at least partially evacuated via the through-hole of the sealing-object and the evacuation channel of the evacuation device.
