Definitions
- the invention relates to an electrical component with electrical connections that contain aluminum on the surface.
- the invention further relates to an arrangement with the component.
- electrical connections made of aluminum are provided.
- Such components can in particular be capacitors.
- Aluminum electrolytic capacitors or else electrochemical double-layer capacitors are particularly suitable.
- electrical connections made of aluminum are preferably used, since the material aluminum is resistant to the aggressive chemical liquids usually found in this type of capacitor.
- aluminum electrolytic capacitors contain chemical substances that chemically attack many metals commonly used as electrical connections.
- the material aluminum has the advantage that it forms a passivation layer made of aluminum oxide on its surface, this passivation layer protecting the aluminum from further damage by an aggressive liquid.
- the known components have the disadvantage that the electrical contacting of the components is difficult due to the passivation layer on the surface of the aluminum connections.
- the passivation layer made of aluminum oxide is an electrical insulator, so that high contact resistances occur when contacting electrical conductors or other electrical components, which are generally undesirable. It is therefore an object of the present invention to provide an electrical component whose electrical contactability is improved.
- An electrical component which has electrical connections which contain aluminum on the surface.
- the aluminum-containing surface has been made solderable in a contact area.
- Making the aluminum-containing surface solderable has the advantage that the formation of an aluminum oxide passivation layer can no longer take place, since solderable metals do not form such a passivation layer.
- the invention is associated with the fact that the aluminum-containing surface of the electrical connections is coated in a contact area with a solderable material.
- a solderable material Materials that do not form a passivation layer are particularly suitable as solderable materials.
- nickel or copper can be used as the solderable material.
- the aluminum-containing surface of the connections is chemically nickel-plated in a contact area.
- the chemical nickel-plating has the advantage that it is an easy-to-carry-out method to apply a solderable metal to the surface of the aluminum.
- the nickel plating of the electrical connections can be carried out, for example, by means of a method which is described in the publication US Pat. No. 4,196,061, the disclosure content of which is expressly referred to here. However, it is also conceivable to copper the electrical connections. Copper plating can also be done chemically.
- a galvanic coating of the electrical connections is less of an option due to the electrically insulating passivation layer on the aluminum.
- the passivation layer on the surface of the aluminum already forms under normal ambient conditions without additional special measures.
- the component In order to further improve the solderability of the electrical connections, it is provided in one embodiment of the component to at least partially tin-plate the surface of the electrical connections coated with the solderable metal.
- a further advantage can be achieved by making the surface of the electrical connections solderable in a contact area.
- the aluminum covered by the passivation layer, which forms the material of the electrical connections in the components according to the prior art, is in general not solderable, so that the components according to the prior art are contacted by clamps, rivets or screws is instructed.
- the electrical connections in the * contact area it is necessary for the electrical connections in the * contact area to have as flat a surface as possible, since otherwise the mechanical contact between different contact elements or between the electrical connection of the component and, for example, one a screw contact mediating screw is only given at some points.
- a flat surface of the electrical connections according to the prior art can achieve that a flat mechanical and electrical contact occurs, which in many cases, however, cannot reduce the ohmic resistance to a satisfactory level.
- solderable electrical connections are now provided in the component specified here, the most flat possible surface of the electrical connections in the contact area is no longer important, as a result of which the technological outlay for producing the electrical contacts can be reduced. It is namely possible with the component specified here forms of electrical connections that deviate from a flat surface without having to do without a sufficiently low ohmic resistance of the contact. In particular, it is possible to use electrical connections that are bent or that have a rough surface.
- the electrical component specified here can in particular be an aluminum electrolytic capacitor.
- all metals used are preferably made of aluminum.
- an aluminum electrolytic capacitor is particularly advantageous in which both the cup-shaped housing, the cover closing the housing, the electrical contacts and the anode and cathode foils forming the actual capacitor are formed from the material aluminum.
- the aluminum has the property that a thin insulating passivation layer is formed on the surface, which enables the setting of very high capacitances in the capacitor.
- the electrical component described here is an electrochemical double-layer capacitor, the same generally applying to this as has already been said for the aluminum electrolytic capacitor.
- An important difference, however, is that the electrodes in an electrochemical double-layer capacitor, for example by carbon containing cloths or carbon-coated aluminum foil is formed.
- the component described here can contain a chemically active liquid, in particular a chemically aggressive liquid, as is usually contained in electrochemical double-layer capacitors or also in aluminum electrolytic capacitors.
- An arrangement with an electrical component is also specified in which at least one connection is soldered to an electrical conductor.
- This arrangement has the advantage that the component can be contacted with a low ohmic resistance by soldering the connection to an electrical conductor.
- connection can also be soldered to another electrical component, which can be, for example, an electrical component described here or another electrical component.
- connection of two electrical components are each soldered to a connecting piece which connects the components to one another in an electrically conductive manner.
- An electrically conductive connection between two components, as described here, can thus be implemented in a simple manner.
- connections of one or more components are soldered to a circuit board.
- solder the connections of the components it is particularly possible to solder the connections of the components to conductor tracks on the circuit board.
- Figure 1 shows an example of an electrical component in a schematic side view.
- FIG. 1A shows an example of a further electrical component in a side view.
- Figure 2 shows an example of an arrangement of two components on a circuit board.
- Figure 3 shows an example of the electrical connection between two components.
- FIG. 1 shows an electrical component 3, which comprises an electrical connection 1.
- the electrical connection 1 contains aluminum on its surface. But it can also be made entirely of aluminum.
- the electrical connection 1 can also run partially inside the electrical component 3.
- the electrical connection 1 is provided with a nickel layer 6.
- This nickel layer 6 can be applied, for example, by chemical nickel plating of the contact area 2.
- the electrical connection 1 When the electrical connection 1 is nickel-plated or generally when the electrical connection 1 is made solderable, it is in principle possible to proceed in two different orders.
- the electrical component 3 In a first order, the electrical component 3 can first be completed with the electrical connection 1 and then the soldering of the electrical connection 1. In another procedure, the electrical connection 1 can first be made solderable and then the electrical connection 1 and the electrical component 3 can be assembled.
- FIG. 1A shows an electrical component corresponding to FIG. 1, but in contrast to FIG. 1 the electrical connection 1 has a clear upward curvature. This is intended to show that the surface of the electrical connection 1 can deviate from a flat surface without the ohmic contact of the electrical connection between the electrical component 3 and a conductor or other components suffering.
- Figure 2 shows two different electrical components 3a, 3b, which are electrically conductively connected to a circuit board 5.
- the electrical connections 1 a, 1 b, which each of the electrical components 3 a, 3 b has, are soldered to electrically conductive conductor tracks of the printed circuit board 5.
- Solder connections 7 are formed, which can be produced, for example, by wave soldering.
- a copper-clad printed circuit board is particularly suitable as the printed circuit board
- FIG. 3 shows a further embodiment of an arrangement described here.
- Two electrical components 3a, 3b are provided.
- the electrical component 3a has an electrical connection la.
- the electrical component 3b also has an electrical connection 1 a.
- a connecting piece 4 is also provided, which can be, for example, a copper plate or a nickel-plated aluminum plate.
- the connector 4 is soldered to the electrical connection ⁇ ' la ' of the ' electrical component 3a.
- the connector 4 is soldered at its other end to the electrical connection la of the electrical component 3b. This creates an electrically conductive connection between the two electrical components 3a . 3b, which has a very low ohmic resistance and thus a high quality.
- the invention described here is not limited to electrolytic capacitors or chemical double-layer capacitors. Rather, the invention can be used for all possible components which have electrical connections whose surface contains aluminum.
- the electrical connections 1, la, lb do not consist of pure aluminum, but that the aluminum is in the form of an alloy.
- the electrical connections 1, la, lb are made of a different material on the inside than on the surface.
