The so-called "packaging technology" is a technology of packaging integrated circuits with insulating plastic or ceramic materials. Take CPU as an example, the actual size and appearance are not the real size and appearance of CPU core, but the packaged products of CPU core and other components. Packaging technology is necessary and crucial for the chip. Because the chip must be isolated from the outside world, in order to prevent the impurities in the air from corroding the chip circuit and causing the electrical performance to drop. On the other hand, the packaged chip is more convenient to install and transport.
Because the quality of packaging technology also directly affects the performance of the chip itself and the design and manufacture of the PCB (printed circuit board) connected with it, it is very important.
