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
Good and poor solder joints caused by amount of solder in dual-wave soldering.
4.1.2
Good and poor solder joints caused by amount of solder in reflow soldering.
