Soldering directions
1
1.1
The nickel barrier layer of the silver/nickel/tin termination prevents leaching of the silver base met-
allization layer. This allows great flexibility in the selection of soldering parameters. The tin pre-
vents the nickel layer from oxidizing and thus ensures better wetting by the solder. The nickel bar-
rier termination is suitable for all commonly-used soldering methods.

1.2
Silver-palladium terminations are used for the large case sizes 1812 and 2220 and for chips in-
tended for conductive adhesion. This metallization improves the resistance of large chips to ther-
mal shock.
In case of conductive adhesion, the silver-palladium metallization reduces susceptibility to corro-
sion. Silver-palladium termination can be used for smaller case sizes (only chip) for hybrid appli-
cations as well. The silver-palladium termination is not approved for lead-free soldering.
