A light radiation emitting device including at least one LED-type device capable of generating a light radiation in a predefined wavelength range and having two electrical contact pads, and a support delimited by first and second opposite sides defining together a thickness of the support, the support supporting at least one LED luminous device and at least one conductive electric track. The electric track is formed of conductive wires. All or part of the conductive wires are bonded to the support along all or part of their length. All or part of the conductive wires have at least one contact portion exposed towards at least one of the first and second sides of the support. Each of the contact pads of the LED-type device is positioned opposite a contact portion of one of the conductive wires and is electrically connected to the contact portion.

Light-emitting device and method for manufacturing same

The invention relates to a chip card manufacturing method. According to this method, there are produced on the one hand, a module including a substrate supporting contacts on one face, and bonding pads on the other, on the other hand, an antenna on a support. The ends of the antenna are linked to lands of connection lands receiving a drop of soldering material on a connection portion. In order to make the soldered electrical connection between the module and the antenna reliable, the bonding pads extend over a zone covering a surface area less than that of the connection portions. The invention relates also to a chip card whose module includes bonding pads extending over a zone covering a surface area less than that of the connection portions.

Method for manufacturing chip cards and chip card obtained by said method

The invention relates to a method for producing a chip card module. According to this method, the following are produced: a module with a substrate having contacts and an electronic chip connected to at least some contacts; an antenna on a carrier, this antenna including two ends, each equipped with a connection land; a cavity in at least one layer of the card at least partially covering the carrier, in order to house the module and to expose the connection lands of the antenna; a first end of a wire is connected directly to a connection pad of the chip, and another portion is connected directly to a connection land of the antenna, after having inserted the module into the cavity.

Method for manufacturing a smart card module and a smart card

A chip card manufacturing method. A module includes a substrate supporting contacts on one surface and conductive paths and a chip on another; and an antenna on a holder, the antenna including a contact pad for respectively connecting to each of the ends thereof. A solder drop is placed on each of the contact pads of the antenna. The holder of the antenna is inserted between plastic layers. A cavity is provided, in which the module can be accommodated and the solder drops remain accessible. The height of the solder drops before heating is suitable for projecting into the cavity. A module is placed in each cavity. The areas of the module that are located on the solder drops are heated to melt the solder and to solder the contact pads of the antenna to conductive paths of the module.

Chip card manufacturing method, and chip card obtained by said method

Method for producing at least one electronic chip support, from a plate that includes a first face intended to be in contact with a chip reader, a second face, covered with a first layer of electrically conductive material and intended to be linked to a radio antenna, and a core made from an electrically insulating material separating the first face from the second face. This method includes steps of drilling at least one through hole through the plate, depositing a layer of electrically conductive material on the first face and chemically etching a first electric circuit and a second electric circuit on the first face and the second face respectively. Prior to the chemical etching step, a step of depositing a third layer of electrically conductive material in the hole or holes, which covers the electrically insulating material in the corresponding hole or holes.
