Bumping technology
Wafer Bumping can be considered as a step in wafer processing where solder spheres are attached to the chip I/O pads before the wafer is diced into individual chips. The bumped dies can then be placed into packages or soldered directly to the PCB, i.e. the COB mentioned earlier. See more Ball Grid Array (BGA) flip chip packages are still the most common type of package used with bumped dies; the bumped die is attached (flipped) onto a substrate in the package that routes … See more Wafer Level Chip Scale Package (WLCSP) is truly a chip scale package because it’s essentially a die sized package with bumps that are essentially balls that can be … See more eWLB, or Embedded Wafer Level BGA, is a packaging technology that was introduced in 2009 by ST and STATS ChipPac.
