Torsten,

The last time I did this type of thing I did the following:

Pre-tin S/S soldering areas with the same solder metallurgy as your solder paste using a very active acid flux (I used a hydrobromic acid type flux), wash thoroughly, then place on PCB like regular component and/or RF shield...

Some adjustment need to be made depending (that word again...) on the joint configuration and part...
