Packaging means that the circuit pins on the silicon chip are wired to the external connectors for connection with other devices, or it refers to the housing used to install semiconductor integrated circuit chips. It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also is connected to the pins of the shell of package by wires through the contacts on the chip, and these pins are connected to other devices by wires on the printed circuit board to combine the internal chip with the external circuits. This is all because the chip must be isolated from the outside to prevent the chip circuits from corrosion and performance-decline due to the contact with air impurities.
On the other hand, the packaged chip is also easier to install and transport. It is crucial because the quality of the packaging directly affects the performance of the chip itself and the design & manufacture of the PCB (printed circuit board) to which it is connected.
An important indicator to measure the advancement of a chip packaging technology is the ratio of chip area to package area, and the closer this ratio is to 1 the better.
