Peter,

You have to have solderable surfaces. Ni, most often, is not one. Often,
these shields, fences, mode blocks, or R/F barriers by other names are
formed of other materials as well. German silver, or so it's called, often
is used and it is a total bitch to solder without very active OA flux
application. We sure don't want that.

Pre-tinned surfaces often do well. Using bolted aluminum mode blocks work
better but for size. I know you're at your customer's mercy here so you
should try fluxing the tabs and tinning them before attempting installation.
Only problem there might be the limited slot sizes.

Earl Moon
