Metal packageDo you know what exactly is the encapsulation? The editor of Keweite will give you a detailed explanation below.

Packaging, Package, is the process of assembling the integrated circuit into the final product of the chip. Simply put, it is to put the integrated circuit die (Die) produced by Foundry on a substrate that plays a supporting role and lead out the pins. Then the fixed packaging becomes a whole.

As a verb, "package" emphasizes the process and actions of placing, fixing, sealing, and lead; as a noun, "package" mainly focuses on the form and type of packaging, the material of the substrate and shell, and the lead, emphasizing that it protects the chip and enhances electric heating It plays an important role in performance and convenient assembly of the whole machine.

Purpose of encapsulation:

Encapsulation refers to connecting the circuit pins on the silicon chip to the external joints with wires to facilitate the connection of other devices. The package form refers to the case for mounting semiconductor integrated circuit chips. It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connecting to the pins of the package shell with wires through the contacts on the chip, and these pins pass the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit. Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport. Since the quality of packaging technology also directly affects the performance of the chip itself and the design and manufacturing of the PCB (printed circuit board) connected to it, it is very important.

An important indicator of whether a chip packaging technology is advanced or not is the ratio of chip area to packaging area. The closer this ratio is to 1, the better.

Through the above explanation, I believe that everyone has a deeper understanding of the term metal package package. If you are interested in it, customers are welcome to consult and purchase!
