What are Multi-Chip FC-BGA Substrates?

Multi-chip FC-BGA substrate is a highly advanced packaging technology that represents the latest progress in integration and performance in the electronics industry. It uses flip chip technology and ball grid array technology to integrate multiple chips on a substrate in a high-density manner. In this package, the soldering method of the chip is reversed, and the connection pins of the chip are directly connected to the solder balls on the substrate rather than through cables or other media. This design not only enables higher integration, but also significantly reduces the size of the circuit board and improves the performance and reliability of electronic equipment.

The core of the multi-chip FC-BGA substrate is its unique flip-chip technology. In traditional packaging technology, the chip is soldered to the substrate upright, but in the multi-chip FC-BGA substrate, the chip is turned upside down and soldered directly to the substrate, making the chip’s pins more compactly distributed on the surface of the substrate. This design not only increases the connection density between chips, but also significantly reduces the electrical path length between chips, thereby improving signal transmission speed and performance.

In addition, the multi-chip FC-BGA substrate also uses ball grid array technology, which means a large number of tiny solder balls are placed on the substrate to connect the chip and the substrate. This technology can not only achieve high-density chip connections, but also provide a good heat conduction path, effectively dissipate heat, and ensure the stability and reliability of the chip during high-performance operation.
