WebOct 1, 2024 · A type of wire bonding, Stand-Off-Stitch Bond (SSB), is widely used in Multi-chip, die-to-die, SiP and light-emitting diodes (LEDs). The SSB process starts with a flat-topped bump bonding on the substrate or die, followed by the formation of a new ball bond (1st bond). The stitch bond (2 nd bond) of that wire is bonded on top of the initial bump.
