Head-in-Pillow (Hip): Head-in-pillow (HiP), also known as ball-and-socket, is a solder joint defect where the solder paste deposit wets the pad, but does not fully coalesce with the BGA sphere. The resulting solder joint forms enough of a connection to have electrical continuity, but lacks mechanical strength. ...

kicthermal.comcomponent, separate from the solder mass/joint. Solder balling occurs if the solder paste spatters (small “explosions”) during reflow, or if the paste slumps and the flux spreads, carrying away solder particles which cannot reflow back into the solder mass. A maximum ramp rate from ambient to peak of 1-1.5°C/second is recommended.
