The invention discloses a PCB (printed circuit board) carried tape for a phone card with a non-contact function, comprising a carried tape body, wherein the middle part of the carried tape body is formed by a plurality of connected single carried tapes. The single carried tapes are respectively provided with chip bearing areas and bonding wire areas, and the carried tape body is in a multi-layer printed circuit board structure. Each layer of printed circuit board of each single carried tape is provided with printed circuits capable of realizing different contact or non-contact or contact and non-contact functions, and different layers are connected through breakover holes. In the precondition of continuing to use most production equipment and processes, the PCB carried tape can be used for packaging and integrating novel phone cards with contact or non-contact functions.
Description
Technical field: [0001] The invention relates to a microelectronic semiconductor packaging technology, an integrated circuit packaging technology and a radio frequency technology, in particular to a carrier tape used for packaging smart cards. 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 usage of mobile phone cards is very large. At present, the mobile phone communication industry is developing towards the route of technological innovation. New technologies are constantly emerging, new functions are increasing, and many old functions are cons...
