The Foundation of Chip Support and Signal Transmission
An IC substrate is a key element in semiconductor packaging, delivering both mechanical support and electrical interconnection for integrated circuits. It shields the bare die and links it to the PCB’s trace network through a multilayer grid of vias and conductors, enabling one or more chips to communicate with the rest of the system. As an intermediate assembly, the substrate secures the IC and carries the internal wiring that bridges the chip to the board.
