4.1
Solder joint profiles / solder quantity
Nickel barrier termination
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.
If the solder meniscus is too high, i.e. the solder quantity is too large, the vise effect may occur.
As the solder cools down, the solder contracts in the direction of the component. If there is too
much solder on the component, it has no leeway to evade the stress and may break, as in a vise.
The figures below show good and poor solder joints for dual-wave and infrared soldering.
4.1.1
Solder joint profiles for nickel barrier termination - dual-wave soldering
Good and poor solder joints caused by amount of solder in dual-wave soldering.
4.1.2
Solder joint profiles for nickel barrier termination / silver-palladium / silver-platinum
termination - reflow soldering
