Packaging technology

The so-called "Packaging Technology" integrated circuit with an insulating plastic or ceramic material packaging technology. The CPU, for example, actually see the size and appearance of the CPU core is not really the size and appearance, but the CPU core and other components of the product after packaging. Packaging technology package is a must for the chip, is also essential. Because the chip must be isolated from the outside world, in order to prevent corrosion of impurities in the air caused by the electrical circuit chip performance degradation. On the other hand, after the chip package and easier to install and transport. Since the quality of packaging technology also play a direct impact on the performance of the chip itself and connected thereto PCB design and manufacture (printed circuit board), so it is crucial.

Packaging can also be said that with the installation of a semiconductor integrated circuit chip shell, it not only plays placed, fixed, sealing, protecting the chip and the enhanced role of thermal performance, but also to communicate with the outside world circuit chip bridge - chip contact with the package leads are connected to the housing pins, which also connect to the other device via a wire to a printed circuit board. Thus, for many IC products, packaging technology are very crucial part.

CPU is used in multi-packaging packaged in plastic or ceramic insulating materials, to improve the chip acts as a sealing and electric properties. Now that the frequency of the processor chip increasing, more powerful, more and more pin count, package shape is also constantly changing.
