WebNov 1, 2005 · The ultrasonic flip chip bonding process is in principle a fairly straightforward one. First, the Au bumps on the bare die and the Au-plated FPC pads are brought into correct alignment. Then, the bumps contact the pads with a low force. The Au-Au metallic bond is generated through a combination of force and ultrasonic vibration. WebThe flip chip (bottom) faces down and is typically attached via solder bumps similar to the larger ones that attach BGA packages to the printed circuit board (also shown here).
