Abstract

The invention discloses an intelligent card module with a coil as well as the realization method thereof. The intelligent card module comprises the coil, wherein the coil is arranged in a carrier tape; a chip is a dual-interface chip, and is mounted on the carrier tape and matched with the coil; and the chip and the carrier tape are packaged into the module by a molding body. In the realization method, the intelligent card module is formed in a way of molding and packaging, flip chip bonding or surface mounting. The intelligent card can be directly used in a contact environment and a non-contact environment.

Description

technical field [0001] The invention relates to a microelectronic semiconductor packaging technology and an integrated circuit packaging technology, in particular to a dual-interface smart card module and a corresponding implementation. Background technique [0002] With the continuous progress of integrated circuit packaging technology, the integration level of integrated circuits is increasing day by day, and the functions are becoming more and more abundant. For the continuous emergence of new application requirements, integrated circuit packaging companies are required to design new types of carrier tapes to meet the new requirements. [0003] For example, in the field of smart card packaging, especially the use of dual-interface smart cards is very large. At present, the smart card industry is developing towards the route of technological innovation. New technologies are constantly emerging, new functions are increasing, and many old functions are constantly being impro...
