Housing for mounting semiconductor integrated circuit chips
The so-called package refers to the shell used to install the semiconductor integrated circuit chip, which not only plays the role of placing, fixing, sealing, protecting the chip and enhancing the thermal conductivity, but also the bridge between the internal world of the chip and the external circuit - the contact on the chip is connected to the pin of the package shell with a wire. These pins, in turn, are connected to other devices through wires on the printed circuit board.
Package is the process of assembling the integrated circuit into the final product of the chip, simply put, is to put the bare chip (Die) of the integrated circuit produced by the foundry on a substrate that plays a bearing role, the pin is drawn out, and then the fixed packaging becomes a whole.
