    “PANEL WITH AN ELECTRICAL CONNECTION ELEMENT, METHOD TO PRODUCE A PANEL WITH AN ELECTRICAL CONNECTION ELEMENT, AND, USE OF A PANEL WITH AN ELECTRICAL CONNECTION ELEMENT” [0001] The present invention relates to a panel with an electrical connection and an economical and environmentally friendly method for its manufacture. [0002] The present invention also relates to a panel with an electrical connection element for motor vehicles with electrically conductive structures, such as heating conductors or antenna conductors. Electrically conductive structures usually connect to the built-in electrical system by means of welded electrical connection elements. Due to the different coefficients of thermal expansion of the materials used, mechanical stresses occur that deform the panels and can cause the panel to break during its manufacture and operation.
    [0003] Solders containing lead have high ductility, capable of compensating for the mechanical stresses that occur between an electrical connection element and the panel due to plastic deformation. However, due to the End of Life Vehicles Directive 2000/53 / EC, solders containing lead need to be replaced with lead-free solders within the European Community. The directive is called, in short, by the acronym ELV (End of Life Vehicles). The objective is to ban extremely problematic components from products due to the massive increase in disposable electronic components. The affected substances are lead, mercury, cadmium and chromium. This refers, among other things, to the implementation of lead-free solder materials in electrical glass applications and the introduction of corresponding substitute products. [0004] EP 1 942 703 A2 discloses an electrical connection element in motor vehicle panels in which the difference in the thermal expansion coefficient of the panel and the electrical connection element is less than 5 x 10-6 / ° C. In order to provide adequate mechanical stability and processability, it is proposed to use a surplus of welding material. The surplus of solder material flows out of the intermediate space between the connecting element and the electrically conductive structure. Surplus welding material causes high mechanical stresses on the glass panel. These mechanical stresses ultimately result in the panel breaking.
    [0005] The objective of the present invention is to provide a panel with an electrical connection element and an economical and environmentally friendly method for its manufacture, by which critical mechanical stresses on the panel are avoided.
    [0006] The purpose of the present invention is accomplished by means of a panel with a connecting element with the following characteristics: - a substrate made of glass with a first coefficient of thermal expansion, - an electrically conductive structure with a layer thickness from 5 pm to 40 pm, preferably from 5 pm to 20 pm, over a region of the substrate, - a connecting element with a second thermal expansion coefficient, where the difference between the first and second thermal expansion coefficients is smaller than 5 x 10-6 / ° C, and - a layer of solder material, which electrically connects the connecting element to subregions of the electrically conductive structure, where the solder material flows out, with a width of outlet flow less than 1 mm in relation to the contact surface of the connection element, from the intermediate space between the connection element and the electrically conductive structure. [0007] The purpose of the present invention is also achieved by means of a panel with a connecting element with the following characteristics: - a substrate made of glass (1) with a first coefficient of thermal expansion, - an electrically conductive structure ( 2) with a layer thickness of 5 pm to 40 pm, preferably from 5 pm to 20 pm, over a region of the substrate (1), - a connecting element (3) with a second coefficient of thermal expansion, where the difference between the coefficients of thermal expansion first and second is greater than or equal to 5 x 10-6 / ° C, and - a layer of solder material (4), which electrically connects the connecting element (3) to sub - regions of the electrically conductive structure (2). [0008] An electrically conductive structure is applied over the panel. An electrical connection element electrically connects to the electrically conductive structure using a weld material in sub-regions. The weld material flows outward, with an output flow width of less than 1 mm, from the intermediate space between the connecting element and the electrically conductive structure. [0009] In a preferred embodiment, the maximum width of the outflow is preferably less than 0.5 and, in particular, close to 0 mm.
    [0010] The maximum width of the outflow is defined as the distance between the outer edges of the connection element and the point of intersection of the weld material, where the weld material falls below a layer thickness of 50 pm. The maximum width of the outflow is measured in the solidified weld material after the welding process.
    [0011] A maximum desired width for the outlet flow is obtained by the appropriate choice of the welding material and the vertical distance between the connection element and the electrically conductive structure, which can be determined by simple experiments. The vertical distance between the connecting element and the electrically conductive structure can be predefined by a suitable process tool, for example, a tool with an integrated spacer.
    [0012] The maximum width of the outlet flow can even be negative, that is, recessed in the intermediate space formed by an electrical connection element and an electrically conductive structure, preferably in the form of a concave meniscus. A concave meniscus is created, for example, by increasing the vertical distance between the spacer and the conductive structure during the welding process while the weld is still in the liquid state.
    [0013] The advantage lies in the reduction of mechanical stresses on the panel, especially in the critical region present with a wide crossing of the weld material. [0014] Preferably, the first coefficient of thermal expansion is 8 x 10-6 / ° C to 9 x 10-6 / ° C. Preferably, the substrate is made of glass with a thermal expansion coefficient, preferably from 8.3 x 10-6 / ° C to 9 x 10-6 / ° C at a temperature range of 0 ° C to 300 ° C.
    [0015] Preferably, the second coefficient of thermal expansion is 8 x 10 '6 / ° C to 9 x 10-6 / ° C, more preferably 8.3 x 10-6 / ° C at 9 x 10- 6 / ° C, at a temperature range of 0 ° C to 300 ° C.
    [0016] The thermal expansion coefficient of the connection element can be less than or equal to 4 x 10-6 / ° C.
    [0017] The electrically conductive structure according to the invention has a layer thickness, preferably from 8 pm to 15 pm and, more preferably, from 10 pm to 12 pm. The electrically conductive structure according to the invention preferably contains silver and, more preferably, silver particles and glass chips.
    [0018] The layer thickness of the weld according to the invention is less than 3.0 x 10'4 m. According to the invention, the solder material preferably contains tin and bismuth, indium, zinc, copper, silver or compositions thereof. According to the invention, the proportion of tin in the solder composition is from 3% to 99.5% by weight, preferably from 10% to 9.5% by weight, more preferably from 15% to 60% by weight. The proportion of bismuth, indium, zinc, copper, silver or compositions thereof in the solder composition according to the invention is from 0.5% to 97% by weight, preferably from 10% to 67% by weight, the proportion of bismuth, indium, zinc, copper or silver can be 0% by weight. The solder composition according to the invention can contain nickel, germanium, aluminum or phosphorus in a proportion of 0% to 5% by weight. The solder composition according to the invention most preferably contains Bi40Sn57Ag3, Sn40Bi57Ag3, Bi59Sn40Ag1, Bi57Sn42Ag1, In97Ag3, Sn95,5Ag3,8Cu0.7, Bi67In33, Bi33In50Sn17, Sn77,2In20Ag2,8, Sn95Ag4Cu1, Sn95Ag4Cu1, Sn99 5 or mixtures of these.
    [0019] The connection element according to the invention preferably contains at least 50% to 75% by weight of iron, from 25% to 50% by weight of nickel, from 0% to 20% by weight of cobalt, from 0% to 1.5% by weight of magnesium, from 0% to 1% by weight of silicon, from 0% to 1% by weight of carbon or from 0% to 1% by weight of manganese.
    [0020] The connection element according to the invention preferably contains at least 55% to 70% by weight of iron, from 30% to 45% by weight of nickel, from 0% to 5% by weight of cobalt, from 0% to 1% by weight of magnesium, from 0% to 1% by weight of silicon or from 0% to 1% by weight of carbon.
    [0021] The connection element according to the invention preferably contains at least 50% to 60% by weight of iron, 25% to 35% by weight of nickel, 15% to 20% by weight of cobalt, from 0% to 0.5% by weight of silicon, from 0% to 0.1% by weight of carbon or from 0% to 0.5% by weight of manganese.
    [0022] The connecting element according to the invention is coated, more preferably, with nickel, tin, copper and / or silver. The connection element according to the invention is coated, more preferably, with 0.1 pm to 0.3 pm nickel and / or 3 pm to 10 pm silver. The connecting element can be plated with nickel, tin, copper and / or silver. Ni and Ag improve the current carrying capacity and corrosion stability of the connection element, as well as wetting with the weld material.
    [0023] The connection element according to the invention preferably contains Kovar (FeCoNi) and / or Invar (FeNi) with an Invar thermal expansion coefficient of 0.1 x 10-6 / ° C at 4 x 10-6 / ° C or a maximum Kovar differential of 5 x 10-6 / ° C in relation to the expansion coefficient of the panel.
    [0024] Kovar is an alloy of iron, nickel and cobalt that has a coefficient of thermal expansion generally around 5 x 10'6 / ° C, which is therefore less than the coefficient of typical metals. The composition contains, for example, 54% by weight of iron, 29% by weight of nickel and 17% by weight of cobalt. In the area of microelectronic technology and microsystems, Kovar is therefore used as housing material or as a subassembly. Subassemblies are, according to the sandwich principle, between the actual substrate material and the material, for the most part, with a significantly higher expansion coefficient. Kovar, therefore, serves as a compensating element that absorbs and reduces thermomechanical stresses caused by the different thermal expansion coefficients of other materials. Similarly, Kovar is used in metal-glass implementations of electronic components and material transitions in vacuum chambers.
    [0025] Invar is an alloy of iron and nickel with a content of 36% by weight of nickel (FeNi36). There is a group of alloys and compounds with the property of having exceptionally low thermal expansion coefficients or, sometimes, negative to certain temperature ranges. Invar Fe65Ni35 contains 65% by weight of iron and 35% by weight of nickel. Up to 1% by weight of magnesium, silicon and carbon are generally melted in order to change the mechanical properties. By melting 5% by weight of cobalt, it is possible to further reduce the coefficient of thermal expansion α. A name for the alloy is Inovco, FeNi33Co4.5 with an expansion coefficient α (20 ° C to 100 ° C) of 0.55 x 10-6 / ° C.
    [0026] If an alloy, such as Invar, with a very low absolute thermal expansion coefficient of less than 4 x 106 / ° C is used, there is an excessive compensation of mechanical stresses by non-critical pressure stresses on the glass or by non-critical traction in the league. Due to the overcompensation of the alloy, the width of the outflow from the intermediate space between the connecting element and the electrically conductive structure becomes negligible.
    [0027] Kovar and / or Invar can also be welded, crimped or glued as a compensation plate over a connection element made, for example, of steel, aluminum, titanium or copper. As a bimetal, it is possible to obtain the favorable expansion behavior of the connecting element in relation to the expansion of the glass. The compensation plate is preferably shaped like a hat.
    [0028] The electrical connection element includes, on the surface facing the welding material, a coating containing copper, zinc, tin, silver, gold or a combination thereof, preferably silver. Thus, the spread of the weld material beyond the coating is prevented and the width of the outflow is limited.
    [0029] The electrical connection element can be designed in the form of a bridge with at least two contact surfaces, as well as in the form of a connection element with a single contact surface.
    [0030] Seen from above, the connecting elements are preferably from 1 mm to 50 mm in length and width, more preferably from 3 mm to 30 mm in length and width and, even more preferably, from 2 mm to 4 mm wide and 12 mm to 24 mm long.
    [0031] The shape of the electrical connection element can establish weld deposits in the intermediate space between the connection element and the electrically conductive structure. The weld deposits and wetting properties of the weld on the connection element prevent the outflow of the weld material from the intermediate space. The weld deposits can be of rectangular, rounded or polygonal design.
    [0032] The distribution of the welding heat and, therefore, the distribution of the welding material during the welding process can be defined by the shape of the connection element. The weld material flows to the hottest point. For example, the bridge may be in the form of a single or double hat in order to advantageously distribute the heat in the connection element during the welding process.
    [0033] The introduction of energy during the electrical connection of an electrical connection element with an electrically conductive structure occurs, preferably, by means of punches, thermodes, piston welding, preferably laser welding, hot air welding, welding by induction, resistance welding and / or ultrasound.
    [0034] The purpose of the invention is accomplished by means of a method to manufacture a panel with a connection element in which: a. welding material is arranged and applied over the connection element in the form of a plate with fixed layer thickness, volume, shape and arrangement, b. an electrically conductive structure is applied to a substrate, c. the connection element with the welding material is placed on the electrically conductive structure, and d. the connection element is welded to the electrically conductive structure. [0035] Preferably, the welding material is applied beforehand to the connection elements, preferably in the form of a nameplate with a layer thickness, volume, shape and arrangement fixed on the connection element.
    [0036] The connection element is welded or crimped to a sheet, braided wire or canvas (not shown) made, for example, of copper and connected to the built-in electrical system (also not shown).
    [0037] Preferably, the connection element is used in heated panels or in panels with antennas in buildings, in particular in cars, railways, aircraft or boats. The connecting element serves to connect the conductive structures of the panel to electrical systems arranged outside the panel. Electrical systems are amplifiers, control units or sources of electrical voltage.
    [0038] We will explain the present invention in more detail with reference to the drawings and exemplary embodiments. In the drawings: figure 1 shows a perspective view of a first embodiment of the panel according to the invention, figure 2 shows a cross section AA through the panel of figure 1, figure 3 shows a cross section through an alternative panel according to the invention, figure 4 shows a cross section through another alternative panel according to the invention, figure 5 shows a cross section through another alternative panel according to the invention, figure 6 shows a perspective view of an alternative embodiment of the panel according to the invention, figure 7 shows a cross section BB through the panel of figure 6, and figure 8 shows a detailed flow chart of the method according to the invention.
    [0039] Figures 1 and 2 illustrate, in each case, a detail of a heating panel 1 according to the invention in the region of the electrical connection element 3. Panel 1 was a simple, thermally prestressed safety glass, 3 mm thick and made of welded lime glass. Panel 1 had a width of 150 cm and a height of 80 cm. An electrically conductive structure 2 in the form of a heat conductive structure 2 was printed on the panel 1. The electrically conductive structure 2 contained silver particles and glass chips. The electrically conductive structure 2 was extended by a width of 10 mm in the terminal region of the panel 1, thus forming a contact surface for the electrical connection element 3. In the terminal region of the panel 1, there was also a cover screen printing (non- illustrated). In the region of the contact surface between the electrical connection element 3 and the electrically conductive structure 2, welding material 4 was applied, which resulted in a durable electrical and mechanical connection between the electrical connection element 3 and the electrically conductive structure 2. Solder material 4 contained 57% by weight of bismuth, 40% by weight of tin and 3% by weight of silver. The welding material 4 was arranged, according to a predefined volume and shape, completely between the electrical connection element 3 and the electrically conductive structure 2. The welding material 4 had a thickness of 250 pm. An outflow of the weld material 4 from the intermediate space between the electrical connection element 3 and the electrically conductive structure 2, which exceeds a layer thickness t of 50 pm, was observed with a maximum outlet flow width b = 0.5 mm. The electrical connection element 3 was an alloy with 54% by weight of iron, 29% by weight of nickel and 17% by weight of cobalt. The electrical connection element 3 is designed in the form of a bridge with a width of 4 mm and a length of 24 mm. The material thickness of the connecting element 3 was 0.8 mm. The contact surface of the connecting element 3 was 4 mm wide and 4 mm long. No critical mechanical stress was observed in panel 1 due to the arrangement of the welding material 4, predefined by the connection element 3 and the electrically conductive structure 2. The connection of the panel 1 with the electrical connection element 3 by means of the electrically conductive structure 2 was lastingly stable.
    [0040] Figure 3 illustrates, in continuation with the exemplary embodiment of figures 1 and 2, an alternative embodiment of the connecting element 3 according to the invention. The electrical connection element 3 was provided, on the surface facing the welding material 4, with a coating containing silver 5. This prevented the propagation of the welding material beyond the coating 5 and limited the flow width output b. The width of the outflow b of the weld material 4 was less than 1 mm. No critical mechanical stress was observed on panel 1 due to the disposition of the welding material 4. The connection of panel 1 to the electrical connection element 3 via electrically conductive structure 2 was durable. [0041] Figure 4 illustrates, in continuation with the exemplary embodiment of figures 1 and 2, another alternative embodiment of the connecting element 3 according to the invention. The electrical connection element 3 contained, on the surface facing the weld material 4, a recess with a depth of 250 pm forming a weld deposit for the weld material 4. It was possible to completely prevent the outflow of the weld material 4 from the intermediate space. The thermal stresses in panel 1 were not critical and a durable mechanical and electrical connection was provided between connection element 3 and panel 1 by means of electrically conductive structure 2. [0042] Figure 5 illustrates, in continuation to the exemplary realization of the figures 1 and 2, another alternative embodiment of the connecting element 3 according to the invention. The electrical connection element 3 has been curved upwards in the terminal regions. The height of the upward curvature of the terminal regions of the glass panel 1 was a maximum of 400 pm. As a result, a space was formed for the welding material 4. The predefined welding material 4 formed a concave meniscus between the electrical connection element 3 and the electrically conductive structure 2. It was possible to completely prevent the flow of material out weld 4 from the intermediate space. The width of the outflow b, approximately equal to 0, was less than zero, largely thanks to the formed meniscus. The thermal stresses in panel 1 were not critical and a durable mechanical and electrical connection was provided between the connecting element 3 and panel 1 by means of the electrically conductive structure 2.
    [0043] Figures 6 and 7 illustrate another embodiment of panel 1 according to the invention, with the connecting element 3 in the form of a bridge. The connecting element 3 contained an alloy containing iron with a coefficient of thermal expansion of 8 x 10-6 / ° C. The thickness of the material was 2 mm. In the region of the contact surfaces of the connection element 3 with the panel 1, compensation members in the form of a hat 6 containing an alloy of iron, nickel and cobalt were applied. The maximum layer thickness of the hat-shaped compensation members 6 was 4 mm. Thanks to the compensation members, it was possible to adapt the thermal expansion coefficient of the connection element 3 to the requirements of the panel 1 and the welding material 4. The hat-shaped compensation members 6 resulted in the best heat flow during the production of the solder connection 4. The heat occurred mainly in the center of the contact surfaces. It was possible to further reduce the width of the outflow b of the weld material 4. Thanks to the low width of the outflow b, less than 1 mm, and the adapted expansion coefficient, it was possible to further reduce the thermal stresses in the panel 1. The thermal stresses on panel 1 were not critical and a durable mechanical and electrical connection was provided between the connecting element 3 and panel 1 by means of the electrically conductive structure 2.
    [0044] Figure 8 represents in detail a method according to the invention for manufacturing a panel 1 with an electrical connection element 3. An example of the method according to the invention for manufacturing a panel with an electrical connection element 3 is presented in this document. In the first step, it is necessary to break the weld material 4 according to the shape and volume. The weld material 4 is broken over the electrical connection element 3. The electric connection element 3 is arranged with the welding material 4 over the electrically conductive structure 2. The electrical connection element is permanently connected 3 to the electrically conductive structure 2 and, therefore, to the panel 1 through the introduction of energy. Example [0045] We produce test samples with panel 1 (3 mm thick, 150 cm wide and 80 cm high), the electrically conductive structure 2 in the form of a heat conductive structure, the electrical connection element 3, the silver layer on the contact surfaces of the connecting material 3 and the welding material 4. We apply the welding material 4 in advance in the form of a plate with fixed layer thickness, volume and shape on the contact surface of the connection element 3. We have connection element 3 with the welding material applied to the electrically conductive structure 2. We weld the connection element to the electrically conductive structure 2 at a temperature of 200 ° C and a processing time of 2 seconds. The outlet flow of the weld material 4 from the intermediate space between the electrical connection element 3 and the electrically conductive structure 2, which exceeded a layer thickness of 50 pm, was observed with a maximum outlet flow width of only b = 0.5 mm. The dimensions and compositions of the electrically conductive structure 2, the electrical connection element 3, the silver layer on the contact surfaces of the connection element 3 and the welding material 4 are given in table 1, figures 1 and 2 and in the description of the figures.
    [0046] In all samples, it was observed that, with a temperature differential of + 80 ° C to -30 ° C, no glass substrate 1 broke or was damaged. It was possible to demonstrate that, shortly after welding, these panels 1 with the welded connection element 3 proved to be stable against a sudden drop in temperature.
    Table 1 Comparative Example 1 [0047] We performed comparative example 1 as well as the first example, with the following differences. The dimensions and components of the electrically conductive structure 2, the electrical connection element 3 and the metal layer on the contact surfaces of the connection element 3 and the welding material 4 are given in table 2. According to the prior art, there we apply the welding material 4 in the form of a plate on the contact surface of the connection element 3 beforehand. We weld the connection element 3 to the electrically conductive structure 2 according to the conventional method. With the outflow of the welding material 4 from the intermediate space between the electrical connection element 3 and the electrically conductive structure 2, which exceeded a layer thickness of 50 pm, an average outlet flow width was obtained b = 2 mm to 3 mm.
    [0048] With a sudden temperature differential of + 80 ° C to -30 ° C, it was observed that the glass substrates 1 showed great damage shortly after welding.
    Table 2 Comparative Example 2 [0049] We carried out comparative example 2 as well as the first example, with the following differences. The dimensions and components of the electrically conductive structure 2, the electrical connection element 3 and the metal layer on the contact surfaces of the connection element 3 and the welding material 4 are given in table 3. According to the prior art, there we apply the welding material 4 in the form of a plate on the contact surface of the connection element 3 beforehand. We weld the connection element 3 to the electrically conductive structure 2 according to the conventional method. With the outflow of the welding material 4 from the intermediate space between the electrical connection element 3 and the electrically conductive structure 2, which exceeded a layer thickness of 50 pm, an average outlet flow width was obtained b = 1 mm to 1.5 mm.
    [0050] With a sudden temperature differential of + 80 ° C to -30 ° C, it was observed that the glass substrates 1 showed great damage shortly after welding.
    Table 3 [0051] The panels according to the invention with glass substrates 1 and electrical connection elements 3 according to the invention have been shown to have better stability against sudden temperature differentials. This result was unexpected and surprised those skilled in the art.
