SPS(Semiconductor Package Substrate)
It is a core part in semiconductor packaging process, which is a high density board of fine circuit that connects semiconductor's electrical signal to the mainboard.
It is used for automotive and various mobile devices that require high reliability.

Overview
- 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.
