Abstract
The utility model relates to a smart card carrier tape, which is provided, on the envelope surface thereof, with a plurality of pads and golden fingers having a plurality of units, in addition to 8 contacts supported by ISO7816 specification and arranged outside the contact surface of the carrier tape, wherein the golden finger units are used for connection with circuits other than the carrier tape, and the pads are used for binding with a chip. The pads are connected with the golden finger units through copper coated wires. These golden finger units can lead the pins of the chip out of the envelope surface so as to expand the interface capability of traditional ISO7816 carrier tape, in addition, subsequent large-scale and efficient production of the carrier tape is facilitated owing to adoption of a golden finger connection mode. Described in the drawings is a perspective view of the carrier tape as seen from the envelope surface, the contact surface of the carrier tape is as shown in an ISO7816 contact schematic diagram, and the contact surface observed is a horizontal mirror view because of perspective. The contact surface comprises a contact and a connection wire for electroplating. The view of the envelope surface of the carrier tape includes the golden fingers, the pads and the copper-coated connection wires between the both, through holes between the contact surface and the envelope surface, and the connection wire for electroplating.
Description
Technical field
The utility model relates to belt for smart card and application of IC cards field.
Background technology
For traditional contact intelligent card, according to the ISO7816 agreement, the contact-making surface of carrier band comprises 8 contacts, power supply,, reset, clock, data, remaining three contact is also decided by applicable cases, also can only have 6 contacts, does not namely contain C4 and the C8 of protocol definition.For double-interface smart card, also need to draw two radio frequency interface contacts in envelope surfaces.No matter be contact intelligent card; or contact type intelligent card; or double-interface smart card; with the communication in the external world all be that nationality carries out communication in these contacts; along with the application of smart card is widened gradually; smart card no longer has been " making mute " equipment of a kind of function singleness; as the carrier with security mechanism; need and more external equipment interaction data, thereby more interface need to be arranged, therefore; just need to be on the basis of original carrier band interface; expand, simultaneously, also must satisfy follow-up efficiently large-scale production.According to the agreement regulation, 8 contacts or 6 contacts can only be arranged on the contact-making surface, all the other more interfaces can only expand on envelope surfaces.
The utility model content
The utility model is included on the envelope surfaces of carrier band more interface is provided, and adopts the form of golden finger so that the processing of product more efficient, be produced on a large scale.
A kind of multiconductor belt for smart card with golden finger, comprise contact-making surface and envelope surfaces, the electric contact of contact-making surface meets the ISO7816 agreement, it is characterized in that envelope surfaces includes electric contact, and the electric contact of envelope surfaces is arranged with the form of golden finger, the electric contact of contact-making surface is linked the electric contact of envelope surfaces by the mode of electroplating blind hole, realize the electrical connection of contact-making surface and envelope surfaces.Corresponding to the electric contact on the envelope surfaces, some pads of having arranged, the electric contact that pad is connected with envelope surfaces connects by covering copper cash.
Belt for smart card as shown in Figure 1, contact-making surface are respectively 8 contacts that meet the ISO7816 agreement: power supply, reset, clock,, data and other three contacts.Envelope surfaces is used for binding smart card tube core.And for the ease of the binding of the pin of smart card tube core, also placed pad, via hole, and golden finger, and be used for connecting golden finger and and pad or via hole cover the copper connecting line.The contact that via hole is set is for the ease of smart card tube core and contact-making surface links to each other, and adopts the metallization via hole, envelope surfaces can be guided in the contact of contact-making surface, and via hole can link to each other with golden finger by covering the copper connecting line.Simultaneously, cover on the copper connecting line at every, also be provided with pad, be used for the binding of smart card tube core, more reasonable in order to guarantee cabling, and cabling do not intersect, and several pads can be set on different positions.Golden finger can make the pin of tube core draw in envelope surfaces, has expanded the interface capability of conventional I SO7816 carrier band, and because what adopt is the golden finger connected mode, is convenient to the follow-up extensive High-efficient Production of carrier band.
Description of drawings
Fig. 1 is the multiconductor belt for smart card envelope surfaces perspective view with golden finger.
Fig. 2 is the multiconductor belt for smart card contact-making surface view with golden finger.
Fig. 3 is the multiconductor belt for smart card envelope surfaces view with golden finger.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 2 is the contact-making surface view of carrier band, and Fig. 3 is the envelope surfaces view of carrier band, and Fig. 1 is the schematic diagram that Fig. 2 and Fig. 3 are combined, and the contact-making surface of seeing forms the horizon glass picture with the figure that directly sees from contact-making surface.Comprise two module carrier band unit in the schematic diagram, perforation is located on both sides in addition.
As shown in Figure 2, be contact-making surface 100 views of carrier band, be used for linking to each other with external equipment, 8 contacts 101 that meet the ISO7816 agreement are provided, respectively power supply, reset, clock,, data and other three contacts, and the connecting line 205 electroplated of location perforation 206 and being used for.
As shown in Figure 3, be envelope surfaces 200 views of carrier band, be used for binding smart card tube core.Be by golden finger (comprising some unit) 201, pad 202, cover the formations such as copper connecting line 203, via hole 204.The purpose that via hole 204 is set is that the contact for the ease of smart card tube core and contact-making surface links to each other, via hole 204 adopts the metallization via hole, envelope surfaces is guided in the contact of contact-making surface, if via hole needs to link to each other with the unit of golden finger 201, can the unit of via hole 204 with golden finger 201 be linked to each other by covering copper connecting line 203, among Fig. 3 the via hole of two pins of VDD-to-VSS of ISO7816 is linked on the golden finger 201 by covering copper connecting line 203, other pin is not linked on the golden finger 201.Cover on the copper connecting line 203 at every, also be provided with pad 202, be used for the binding of smart card tube core, more reasonable in order to guarantee cabling, and cabling do not intersect, pad 202 can arrange several, in different positions.At first, the smart card tube core is placed on the envelope surfaces 200, the pin of smart card tube core, according to correct logical relation, be connected pad 202 or via hole 204 with envelope surfaces by gold thread or aluminum steel and connect, for linking to each other with pad 202, article one, cover copper connecting line 203 and at the diverse location of envelope surfaces pad 202 some, same logic is arranged, more reasonable, non-cross for line is distributed, can seek a suitable pad 202 and connect.Then, cover copper connecting line 203 pad 202 or via hole 204 are connected on the golden finger 201, and be connected circuit with the belt for smart card outside by golden finger and connect.Adopt the form of golden finger, can utilize welding or adhesive technology to be connected with external circuit all interface signals are disposable.For the follow-up fabrication of carrier band provides great convenience, production efficiency and product yield have greatly been improved.
