    GLAZING PROVIDED WITH AN ELECTRICALLY CONDUCTIVE DEVICE WITH IMPROVED WELDING AREAS
    The present invention relates to a glazing unit comprising an electrical connection element, its manufacturing process and its use in the field of automotive glazing units.
    The invention relates more particularly to glazing for automobiles equipped with an electrical function, such as for example heated or deicing glazing or glazing fitted with antenna. In glazing comprising heating networks, antennas or other sensors, a series of narrow bands (also called “tracks”) of resistance are deposited on the surface of a sheet of glass, before the bending operations and / or quenching, so that the electroconductive composition can be baked during these shaping operations. The composition of the electrically conductive paste is made of a pasty suspension of metallic silver and a frit (i.e. a glass with a low melting point) in an organic binder. These resistance bands lead to wider collecting bands, located near the edges of the glazing. These busbars, also called bus bars, or "busbar" according to the commonly used English terminology, are generally made of a composition identical to that of the resistance bands and are deposited simultaneously and in the same way. These strips are connected to a power supply system via connectors soldered to the electrically conductive paste. The welding of the different elements together is a critical point in the manufacturing process for this type of glazing. Indeed, due to the differences between the coefficients of thermal expansion of the materials used at the welding points, tensions appear during the manufacture and handling of the glazing, inducing embrittlement and the appearance of cracks in the glazing, in particular at the level connectors. Current tests imposed by car manufacturers tend to be more stringent. Indeed, the aging tests carried out on the connectors, and in particular on the conditions of the temperature cycle tests impose variations over relatively wide temperature ranges (between -40 ° C + 105 ° C) and also under a voltage of 14V during the temperature rise phases. These conditions cause additional local heating and correspond to local temperatures which can range up to approximately 120 ° C. The higher temperatures reached can lead to greater thermal expansion of the connector and the solder alloy, which leads to greater stresses on the electrical connection element as a whole. So that the glazing provided with connector and alloy can pass the criteria imposed by the new increasingly rigorous tests, it is necessary to use for the electrically conductive tracks silver pastes which have certain specificities, in particular in terms of composition, deposited thickness and resistivity. Conventionally, in a glazing provided with electrical networks, the entire network is made from a single type of silver paste: thus, in the case of heated glazing, the wires of the heating network and the zones solder are made with a silver paste with special characteristics that limit the risk of the appearance of cracks or mechanical stresses at the weld area where the solder alloy is located. Thus, at the weld zones, so that the glazing provided with connectors and alloy can pass the criteria imposed by these severe tests, it may be necessary for the systems to use two successive layers of silver paste: the first layer of dough is that connected to the entire electrical network and the second layer is that which provides better mechanical performance after welding. The two layers are thus superimposed, generally on a layer of black enamel allowing to mask the whole. The constraints imposed by the choice of silver pasta with certain properties can lead to additional costs linked to the specific characteristics of the paste. However, there is no particular technical advantage in using a particular silver paste for the entire electrical network, since only the soldering zone is the sensitive zone. In particular in order to limit costs, we are currently seeking to develop new glazing schemes fitted with electrical connection elements, adapted in particular to the increasingly stringent requirements of manufacturers or equipment manufacturers and to the latest regulations. This is the context for the present invention.
    The invention relates to a glazing unit consisting of a glass substrate, at least part of which comprises an electrically conductive element consisting of electrically conductive tracks of metallic conductive paste forming the electrical network and welded to a connector by a solder alloy at a weld zone, the glazing comprising a single layer of silver paste at the weld zone, this single layer ensuring the electrical contact of the conductive element.
    Unlike the electrical connection systems described in the prior art which comprise two superimposed layers of metallic conductive paste at the weld zone, the glazing according to the present invention comprises only a single layer of conductive electrical paste.
    Thus, it is possible to dissociate the metallic conductive pastes used, on the one hand, for the electrical network as a whole and, on the other hand, for the soldering zone enabling electrical contact to be made with the conductive element. It therefore becomes possible to limit, for example, the use of a particular metallic conductive paste to the soldering zone exclusively.
    Advantageously, the metallic conductive paste at the weld zone is different from the metallic conductive paste used for the rest of the electrical network. The composition of the layer of metallic conductive paste at the soldering zone can therefore be different from the layer of metallic conductive paste used for the entire electrical network. The choice of metallic conductive paste which forms the single layer at the solder area is therefore made so as to be compatible with the connectors used and the solder alloys. Preferably, the silver paste at the soldering zone comprises before sintering between 60 and 88% by weight of silver, and after sintering, therefore baking at a temperature between 550 ° C and 700 ° C between 90 and 97 % by weight of silver, the rest being glass frit.
    By way of example, when the solder alloy is a lead-free alloy, it is preferable to use a metallic conductive paste at the solder zone which has certain specificities making it possible to ensure good compatibility between the solder alloy and the connector and thus limit the risk of cracking. This paste is a silver-based paste having a resistivity, measured at a temperature of 25 ° C, less than or equal to 3.5 μΩ.ατι.
    The thickness of the layer of metallic conductive paste at the soldering zone can therefore be different from the layer of metallic conductive paste used for the entire electrical network.
    Preferably, the layer of metallic conductive paste at the weld zone has a thickness of between 5 and 20 μm, said thickness being measured after sintering. Even more preferably, this thickness is between 7 and 15 μm.
    The alloy used to solder the electrical connector to the electrically conductive track in silver is for example an alloy based on tin, silver and copper. It is an alloy considered "lead-free", meeting the standards imposed by the European directive. By way of example, the alloy can comprise from 90 to 99.5% by weight of tin, preferably from 93 to 99% by weight and even more preferably from 95 to 98% by weight of tin. It also comprises, in addition to tin, 0.5 to 5% by weight of silver and 0 to 5% by weight of copper. The alloy may also include bismuth, indium, zinc and / or manganese. The solder alloy is placed on the lower parts of the electrical connector. The thickness of the solder alloy layer is preferably less than or equal to 600 μm and is even more preferably between 150 and 600 μm.
    The electrical connector is made of a metallic material and the choice of metal used can be adapted according to the welding alloy in particular. The connector can be copper. For lead-free solder alloys, it is for example steel or titanium, these materials having lower thermal expansion coefficients than copper. Preferably, in the case of a lead-free solder alloy, the electrical connector is made of stainless steel, that is to say of steel comprising at least 10.5% by weight of chromium. This type of connector has the advantage of being compatible with solder alloys based on tin, copper and silver. It is indeed necessary that the different materials have thermal expansion coefficients which make it possible to use them jointly, without risking generating too great mechanical stresses which would cause zones of weakness and the propagation of cracks.
    The electrical connector preferably has a thickness of between 0.1 and 2 mm, more preferably between 0.2 and 1 mm and even more preferably between 0.3 and 0.8 mm. It is positioned on the soldering area, specifically where there is only one layer of metallic conductive paste.
    The connector may have a coating or wetting layer based on nickel, copper, zinc, tin, silver, gold or their alloys, on the surface which is in contact with the solder alloy. Preferably, this coating is based on nickel and / or silver. The thickness of this coating is preferably between 0.1 μm and 0.3 μm for nickel and from 3 to 20 μm for silver.
    The electrical connector may have on its underside intended to be placed on the substrate at least two studs or at least one spacer which make it possible to ensure that the connection between the connector and the conductive silver layer is correctly made by means of the welding alloy and thus improve the quality of the welding.
    The substrate on which the electrical connection system is placed is preferably made of glass, and more particularly of flat glass, for example manufactured by a float process (or “float” process) in which the molten glass is poured onto a metal bath in fusion. It can for example be a quartz glass, a borosilicate glass, an aluminosilicate glass and / or a soda-lime glass. The substrate can also be of the polymeric type, and can comprise polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polybutadiene, polynitriles, polyester, polyurethane, polyvinyl chloride, polyacrylates, polyamide, polyethylene terephthalate and / or their copolymers or their mixtures. The substrate is preferably transparent. It has a thickness between 0.5 mm and 25 mm, and preferably between 0.5 and 10 mm.
    The substrate can be tempered glass or non-tempered glass. By using tempered glass, the surface layer is reinforced, which therefore becomes more resistant, which makes it easier to highlight the embrittlement phenomena caused by the presence of the electrical connection system.
    The invention also relates to a method for manufacturing a glazing unit as described above. The method comprises at least the following steps:
    - depositing metallic electroconductive tracks to form the electrical network on at least part of the glass substrate,
    - deposit of a single layer of metallic conductive paste at the solder zone between the electrically conductive tracks and the connector, the electrical contacts being effected at the level of this single layer,
    - possibly drying of the layers of metallic conductive pastes, - sintering of the layers of metallic conductive pastes, then - welding of the connector at the soldering zone.
    The deposition of the metal electroconductive tracks and the layer of metallic conductive paste at the soldering zone are carried out by methods known to those skilled in the art. The deposition steps are preferably carried out by screen printing, by digital printing. Wheat can also be done by any other known technique. When the deposition is carried out by screen printing, different screen screens can be used for the deposition of the electrically conductive tracks constituting the electrical network and for the deposition of the layer of conductive metallic paste at the soldering zone. The choice of screens is made in particular according to the thickness of the layer which one wishes to deposit on the glazing, and also according to the composition of the metallic conductive paste.
    The drying step for the layers of metallic conductive pastes is optional, depending on the technique used for depositing the layers. 9 the deposition is carried out by screen printing, it is desirable for a layer drying step to take place, at approximately 150 ° C., before the sintering step. An intermediate drying step can also be carried out after the step of depositing the metallic electroconductive tracks forming the electrical network and before the deposition of the layer of metallic conductive paste at the soldering zone. When the conductive layers are deposited by digital printing, it is not always necessary to dry the conductive layers before the sintering step.
    Prior to the deposition steps described above, a layer of black enamel can advantageously be deposited on the glazing, in particular at the locations of the weld zones in order to mask them and make them invisible. Again, the presence of this layer of enamel is optional.
    The sintering step is a step of cooking in air at a temperature between 550 ° C. and 700 ° C. for a period varying from 2 to 10 minutes. The silver sintered enamel is in solid form. Once the sintering step has been carried out, the contact lugs or connectors can then be soldered to allow electrical supply of the conductive wires.
    Welding of the connector on the silver electrically conductive track can be carried out by punching, by piston welding, by microflamme welding, by laser welding, by hot air welding, by induction welding, by resistive welding and / or with ultrasound. . The term "welding" is used in the present invention to speak indifferently of soldering, welding or welding.
    The present invention also relates to the use of a glazing unit comprising at least one electrical connection system as described above, in buildings or vehicles, in particular motor vehicles, railway vehicles or airplanes. Glazing is used in particular as windshields, side windows, heated rear windows or roof or fitted with an antenna or any other electrical function placed on or in the glazing.
    The figures below illustrate the invention. Figure 1 is a conventional electrical connection diagram, used in particular in the case of lead solders. Figures 2 to 4 are electrical connection diagrams for glazing according to the present invention.
    The glazing shown in Figure 1 is a glazing (1) used for example as a rear window equipped with conductive son (2) heating, used in particular for defrosting. A black enamel outline (3) is deposited on the periphery of the glazing to hide the electrical connection areas. During the manufacture of such glazing, the first layer deposited is that corresponding to the contour (3), the heating wires (2) then being deposited on this contour. Two welding zones (4a, 4b) and electrical connection are shown in this figure and are enlarged. Zone 4a corresponds to a weld zone on which a connector of “button” shape will be placed, while in zone (4b), the connector will be of oblong shape. At the soldering zone (4a), a layer of metallic conductive paste (5a) of the same composition as that of the heating wires iso (2) is deposited, in the form of a disc of the same shape as the connector. This layer is then covered with a second silver paste (6a) which has the characteristics necessary to allow welding with the solder alloy and the connector itself. At the weld area. At the soldering zone (4a), two layers of metallic conductive paste (5a) and (6a) are therefore superimposed, the zone (5a) being the busbar zone and the zone (6a) being the soldering zone of the connector. For the soldering zone (4b), two successive layers (5b) and (6b) of metallic conductive pastes are superimposed by adapting the shape of the soldering zone to that of the connector, the zone (5b) being the busbar zone and the zone (6b) being the soldering zone of the connector.
    FIG. 2 represents a glazing according to the invention in which the weld zones (7a) and (7b) comprise only a single layer of metallic conductive paste. The single layer (8a, 8b) which is at the level of the soldering zone is that which makes it possible to make the electrical link with the heating wires (2) by means of the busbar zone (2b) corresponding to a paste. metallic conductor of the same composition as that used for the heating wires (2).
    FIG. 3 shows another connection diagram of a glazing unit according to the present invention. In this configuration, the weld zone (9) comprises a part consisting of a single layer (9a) of conductive metallic paste, this part being in direct contact to ensure the electrical connection with a strip of conductive paste used for the wires. heated (2). The connector is positioned on the part (9a) which comprises only one layer. The transition zone (9b) located around the part (9a) is the only zone in which two layers of metallic conductive pastes are superimposed. This transition zone does not correspond to the welding zone on which the connector will be positioned.
    FIG. 4 shows yet another electrical connection diagram 5 of a glazing unit according to the invention in which the welding zone (10) comprises only a single layer of metallic conductive paste (10a) deposited directly on the layer of black enamel of the outline (3). In the same way as in FIG. 3, the transition zone (10b) is the zone at the level of which two layers of metallic conductive pastes are superimposed, this transition zone is not the weld zone. The connector is positioned on the zone (10a) which comprises only a single layer of metallic conductive paste.
