FC-CSP(Flip Chip-CSP) means that the chip mounted in the PCB is turned over. Compared to the general CSP, the difference is that the connection between the semiconductor chip and the substrate is not wire bonding, but bumps. Since it does not require Wire-Bonding, it is much smaller than those products that go through the general wire bonding process. In addition, many chips and the PCB are connected at the same time, in contrast to wire bonding, which requires you to connect one at a time. Moreover, the connection length is much shorter than in wire bonding, so the performance can be improved.
