BOC (Board on Chip)
BOC is the substrate that connects bonding pad on substrate to the bonding pad of chip by using wire-bonding through the central slot.
It has the bonding and solder side of the substrate in one plane. It replaced the previous lead frame into laminated substrate, which enables I/O pins to diversify and chip to stack vertically, thus it is widely used in memory chip as it is easy to achieve high speed & high density.
