What is encapsulation? Why is encapsulation useful?

Packaging is the process of assembling an integrated circuit into the final product of a chip. Simply put, the integrated circuit die produced by OEM is placed on a bearing substrate, the pins are led out, and then fixed and packaged into a whole.

Because the chip must be isolated from the outside world, to prevent impurities in the air from corroding the chip circuit, resulting in the decline of electrical performance. On the other hand, the packaged chip is also 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 to it, it is very important.
