مقدمة
IC carrier board packaging frame refers to a key special basic material used for IC card module packaging. It mainly protects the chip and serves as the interface between the integrated circuit chip and the outside world. Its form is ribbon, usually golden yellow.
Usage Process
The specific usage process is as follows: أولاً, the IC card chip is attached to the IC card packaging frame by a fully automatic placement machine, and then the contacts on the IC chip are connected to the nodes on the IC card packaging frame with a wire bonding machine. The connection of the circuit, and finally the use of packaging materials to protect the integrated circuit chip to form an integrated circuit card module, which is convenient for subsequent applications.
BGA Architecture and Manufacturing Process
The IC carrier board is also a product based on the BGA (Ball Grid Array) architecture. The manufacturing process is similar to that of PCB products, but the precision is greatly improved. The manufacturing process is different from PCB. IC substrate has become a key component in IC packaging, gradually replacing part of the lead frame (Lead Frame) application.
Integrated Circuit
An integrated circuit integrates a general-purpose circuit on a chip. It is a whole. Once it is damaged internally, the chip is also damaged.

The PCB can solder the components by itself, and replace the components if it is broken.
IC Carrier Board
عمومًا, the carrier board on the chip, the board is very small, usually the size of a 1/4 fingernail, the board is very thin (0.2~0.4mm), the material used is FR-5, BT resin, and the circuit is 2mil/About 2mil. It is a high-precision board that used to be generally produced in Taiwan, but now it is trending towards the mainland. The industry’s yield rate is 75%. The unit price of this kind of board is very high, generally bought according to PCS.
