All EPCOS MLVs with nickel barrier termination are suitable and fully qualiyfied for lead-free sol-
dering. The nickel barrier layer is 100% matte tin-plated.
3.3
AgPd-terminated MLVs are mainly designed for conductive adhesion technology on hybrid materi-
al. Additionally MLVs with AgPd termination are suitable for reflow and wave soldering with SnPb
solder.
Note:
Lead-free soldering is not approved for MLVs with AgPd termination.
3.4
All EPCOS CU types with tinned termination are approved for lead-free and SnPb soldering.
3.5
All EPCOS SHCV types with tinned termination are approved for lead-free and SnPb soldering.

If the meniscus height is too low, that means the solder quantity is too low, the solder joint may
break, i.e. the component becomes detached from the joint. This problem is sometimes interpret-
ed as leaching of the external terminations.
