Cup wire bond

WebWire bonding always requires a preceding die attachment process to mount the die onto the substrate, such as a leadframe or multilayer substrate. One distinguishes polymer die bonding, solder die bonding, and glass die bonding ( Tummala and Rymaszewski 1989, 1997 ), with polymer die bonding being the most common method.

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.
