Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines elektrischen Bauelements, insbesondere zur Herstellung eines elektrischen Bauelements mit einer temperaturabhängigen Widerstandscharakteristik. Die Erfindung betrifft des Weiteren ein elektrisches Bauelement, insbesondere ein elektrisches Bauelement mit einer temperaturabhängigen Widerstandscharakteristik.The invention relates to a method for producing an electrical component, in particular for producing an electrical component with a temperature-dependent resistance characteristic. The invention further relates to an electrical component, in particular an electrical component with a temperature-dependent resistance characteristic.
Zur Messung von Temperaturen können elektrische Bauelemente mit einem temperaturabhängigen Widerstandsverhalten eingesetzt werden. Bei NTC-Bauelementen nimmt der elektrische Widerstand beispielsweise mit steigender Temperatur ab. Derartige elektrische Bauelemente weisen ein Material auf, dessen Widerstandswert von der Umgebungstemperatur abhängig ist. Das temperaturempfindliche Widerstandsmaterial ist üblicherweise in einem Gehäuse des Bauteils, beispielsweise einem SMD-Gehäuse, angeordnet. Zum Messen einer Temperatur eines Körpers werden die Bauelemente üblicherweise mit ihrem Gehäuse auf der Oberfläche des Körpers angeordnet.Electrical components with temperature-dependent resistance behavior can be used to measure temperatures. For example, with NTC components, the electrical resistance decreases as the temperature rises. Such electrical components have a material whose resistance value depends on the ambient temperature. The temperature-sensitive resistance material is usually arranged in a housing of the component, for example an SMD housing. To measure the temperature of a body, the components are usually arranged with their housing on the surface of the body.
Der Nachteil einer derartigen Anordnung besteht darin, dass die thermische Ankopplung des Materials mit der temperaturabhängigen Widerstandscharakteristik an den Körper, dessen Temperatur ermittelt werden soll, aufgrund des umgebenden Gehäuses des Bauelements nicht optimal ist. Beispielsweise ist zwischen dem temperaturempfindlichen Material und dem Gehäuse des Bauelements ein Luftspalt vorhanden, durch den die Wärmeübertragung von der Oberfläche des Körpers auf das temperaturempfindliche Material beeinflusst und die Temperaturmessung letztendlich verfälscht wird.The disadvantage of such an arrangement is that the thermal coupling of the material with the temperature-dependent resistance characteristic to the body whose temperature is to be determined is not optimal due to the surrounding housing of the component. For example, there is an air gap between the temperature-sensitive material and the housing of the component, through which the heat transfer from the surface of the body to the temperature-sensitive material and the temperature measurement is ultimately distorted.

Ein Anliegen der vorliegenden Erfindung ist es, ein Verfahren zur Herstellung eines elektrischen Bauelements anzugeben, bei dem die Ankopplung eines in Bezug auf seinen Widerstand temperaturempfindlichen Materials an eine Oberfläche eines Körpers, dessen Temperatur ermittelt werden soll, verbessert ist. Es soll des Weiteren ein elektrisches Bauelement angegeben werden, bei dem die Ankopplung des in Bezug auf seinen Widerstand temperaturempfindlichen Materials an die Oberfläche eines Körpers, dessen Temperatur bestimmt werden soll, verbessert ist.An aim of the present invention is to provide a method for producing an electrical component in which the coupling of a material that is temperature-sensitive in terms of its resistance to a surface of a body whose temperature is to be determined is improved. Furthermore, an electrical component is to be provided in which the coupling of the material that is temperature-sensitive in terms of its resistance to the surface of a body whose temperature is to be determined is improved.
Eine Ausführungsform eines Verfahrens zur Herstellung eines derartigen elektrischen Bauelements ist im Patentanspruch 1 angegeben. Das Verfahren sieht das Bereitstellen eines Trägerelements und das Bereitstellen eines Materials, das einen temperaturabhängigen Widerstand aufweist, als ein nichtgesintertes, kalziniertes Metalloxid vor. Das Material umfasst eines von Nickeloxid, Manganoxid, Kupferoxid und Zinkoxid oder Kombinationen davon. Das Material wird auf einer Oberfläche des Trägerelements zum Erzeugen einer Widerstandschicht aufgebracht. Zur Anbindung der Widerstandsschicht an das Trägerelement wird die Widerstandsschicht nachfolgend gesintert.An embodiment of a method for producing such an electrical component is specified in
Wenn die Oberflächentemperatur eines Körpers, beispielsweise die Oberflächentemperatur eines Behälters, gemessen werden soll, ist es erforderlich, dass zwischen dem Körper und der temperaturabhängigen Widerstandsschicht des Bauelements eine elektrische Isolation vorliegt. Des Weiteren soll zwischen der Oberfläche des Körpers, dessen Temperatur gemessen werden soll, und dem temperaturempfindlichen Material der Widerstandsschicht eine gute thermische Wärmleitfähigkeit vorhanden sein. Vorzugsweise wird daher für das Trägerelement ein nichtelektrisch leitfähiges Material verwendet. Für die Widerstandsschicht kann eine elektrisch leitfähige Keramik, beispielsweise im Falle eines NTC-Bauelements ein NTC-Thermistormaterial, verwendet werden.If the surface temperature of a body, for example the surface temperature of a container, is to be measured, it is necessary that there is electrical insulation between the body and the temperature-dependent resistance layer of the component. Furthermore, there should be good thermal conductivity between the surface of the body whose temperature is to be measured and the temperature-sensitive material of the resistance layer. Preferably, a non-electrically conductive material is therefore used for the carrier element. For the resistance layer An electrically conductive ceramic, for example an NTC thermistor material in the case of an NTC component, can be used.
Durch Kombination eines nichtelektrisch leitfähigen Trägermaterials mit einer elektrisch leitfähigen Keramik wird mit dem angegebenen Verfahren ein neues Herstellungsverfahren für temperaturempfindliche elektrische Bauelemente bereitgestellt, mit dem sich Bauelemente fertigen lassen, dessen Widerstandsschicht über das Trägerelement gut an einen Untergrund angekoppelt werden kann.By combining a non-electrically conductive carrier material with an electrically conductive ceramic, the specified method provides a new manufacturing process for temperature-sensitive electrical components, with which components can be manufactured whose resistance layer can be well coupled to a substrate via the carrier element.
Für die Widerstandsschicht wird wie oben beschrieben ein nichtgesintertes Material verwendet. Es kann beispielsweise ein kalziniertes Metalloxidpulver verwendet werden. Aus diesem Ausgangsmaterial wird eine siebdruckfähige Keramikpaste hergestellt. Die Paste kann auf das Trägerelement in Form von beliebigen Strukturen aufgebracht werden. Die Strukturen können beispielsweise auf das Material des Trägerelements gedruckt werden. Zum Zeitpunkt der Bedruckung besitzt das temperaturempfindliche Material der Widerstandsschicht noch nicht seine Endeigenschaften. Die Endeigenschaften nimmt das Material erst nach dem Sinterprozess an.As described above, a non-sintered material is used for the resistance layer. For example, a calcined metal oxide powder can be used. A screen-printable ceramic paste is made from this starting material. The paste can be applied to the carrier element in the form of any structure. The structures can, for example, be printed onto the material of the carrier element. At the time of printing, the temperature-sensitive material of the resistance layer does not yet have its final properties. The material only takes on its final properties after the sintering process.
Die Stabilität einer derartigen Anordnung aus einem nichtgesinterten Material, das einen temperaturabhängigen Widerstand aufweist, und einem Trägerelement, an das das Material erst nach dem Aufdrucken der Paste durch einen Sinterprozess fest angebunden ist, weist eine deutlich höhere Stabilität auf, als wenn Pasten, insbesondere gesinterte Pasten, verwendet würden, die bereits beim Aufbringen auf das Trägerelement ihre Endeigenschaften besitzen. Durch das Aufdrucken des Materials mit dem temperaturabhängigen Widerstand auf das Trägerelement können komplexe Widerstandsstrukturen realisiert werden. Des Weiteren bietet das Verfahren den Vorteil der Miniaturisierung.The stability of such an arrangement made of a non-sintered material that has a temperature-dependent resistance and a carrier element to which the material is only firmly bonded by a sintering process after the paste has been printed on is significantly higher than if pastes, in particular sintered pastes, were used that already have their final properties when applied to the carrier element. By printing the material Complex resistance structures can be realized with the temperature-dependent resistance on the carrier element. The process also offers the advantage of miniaturization.
Mittels des angegebenen Herstellungsverfahrens lässt sich somit ein Temperatursensorelement realisieren, dessen sensitive Keramikschicht über einen Sinterprozess an das elektrisch nicht leitfähige, jedoch thermisch hochleitfähige Material des Trägerelements fest angebunden wird. Damit können Temperaturmessapplikationen bedient werden, bei denen die Ankopplung eines Temperatursensorelements über flächige Oberflächen erfolgt, wobei eine maximale thermische Ankopplung erfolgt und die thermische Masse minimiert werden kann.Using the specified manufacturing process, a temperature sensor element can be produced whose sensitive ceramic layer is firmly bonded to the electrically non-conductive but thermally highly conductive material of the carrier element via a sintering process. This can be used for temperature measurement applications in which a temperature sensor element is coupled via flat surfaces, whereby maximum thermal coupling is achieved and the thermal mass can be minimized.
Eine Ausführungsform eines derartigen elektrischen Bauelements ist im Patentanspruch 9 angegeben. Das elektrische Bauelement umfasst ein Trägerelement und eine Widerstandsschicht aus einem Material, das einen temperaturabhängigen Widerstand aufweist. Das Material enthält ein kalziniertes Metalloxid umfassend eines von Nickeloxid, Manganoxid, Kupferoxid und Zinkoxid oder Kombinationen davon. Die Widerstandsschicht ist auf einer Oberfläche des Trägerelements angeordnet und durch einen Sinterprozess an das Trägerelement angebunden.An embodiment of such an electrical component is specified in claim 9. The electrical component comprises a carrier element and a resistance layer made of a material that has a temperature-dependent resistance. The material contains a calcined metal oxide comprising one of nickel oxide, manganese oxide, copper oxide and zinc oxide or combinations thereof. The resistance layer is arranged on a surface of the carrier element and bonded to the carrier element by a sintering process.

In einem Verfahrensschritt A wird zunächst ein Trägerelement 10 bereitgestellt. In einem Verfahrensschritt B wird des weiteren ein Material, das einen temperaturabhängigen Widerstand aufweist, bereitgestellt. In einem Verfahrensschritt C wird das Material auf einer Oberfläche O10 des Trägerelements 10 zum Erzeugen einer Widerstandsschicht 20 auf dem Trägerelement aufgebracht. Nachfolgend erfolgt in einem Verfahrensschritt D das Sintern der Widerstandsschicht 20 zur Anbindung der Widerstandsschicht 20 an das Trägerelement 10. In einem Verfahrensschritt E erfolgt das Aufbringen von Elektroden 30a, 30b an das bis dahin gefertigte elektrische Bauelement zum Anlegen einer Spannung an die Widerstandsschicht 20 des Bauelements. Mindestens eine der Elektroden 30a und 30b kann auf einer Oberfläche O20 der Widerstandsschicht 20 oder auf einer weiteren Oberfläche U10 des Trägerelements 10 angeordnet werden.In a process step A, a

Im Verfahrensschritt B wird das Material der Widerstandsschicht 20 vor dem Aufbringen der Widerstandsschicht auf dem Trägerelement 10 beispielsweise als ein Material, das nicht gesintert ist, bereitgestellt. Das Material der Widerstandsschicht 20 kann als ein kalziniertes Metalloxid, das nicht gesintert ist, bereitgestellt werden. Insbesondere kann die Widerstandsschicht 20 im Verfahrensschritt B aus einem Material aus Nickeloxid, Manganoxid, Kupferoxid, Zinkoxid oder aus Kombinationen davon bereitgestellt werden.In method step B, the material of the

Gemäß einer möglichen Ausführungsform des Verfahrens kann zunächst im Verfahrensschritt B vor dem Aufbringen der Widerstandsschicht 20 auf das Trägerelement 10 das Material der Widerstandschicht 20 als eine siebdruckfähige Keramikpaste bereitgestellt werden, die noch nicht gesintert ist und daher noch nicht ihre Endeigenschaften aufweist. Im nachfolgenden Verfahrensschritt C kann vor dem eigentlichen Sintern der Widerstandsschicht 20 eine Struktur der Widerstandsschicht 20 auf das Trägerelement 10 gedruckt werden. Die Struktur der Widerstandsschicht 20 kann insbesondere mittels eines Siebdruckverfahrens auf das Trägerelement 10 gedruckt werden, bevor die Widerstandsschicht gesintert wird und dadurch fest an das Trägerelement angebunden wird.According to a possible embodiment of the method, in method step B, before applying the
Die druckfähige Paste kann als eine Metalloxid-Keramik-Pulvermischung mit einer NTC-Charakteristik ausgebildet sein. Da die Paste beim Aufbringen auf das Trägerelement noch nicht gesintert ist, besitzt das Material der Widerstandsschicht 20 zum Zeitpunkt der Bedruckung noch nicht seine Endeigenschaften, die es erst nach dem Sinterprozess annimmt. Die Stabilität des temperaturempfindlichen elektrischen Bauelements ist daher höher als wenn Pasten verwendet würden, die bereits beim Aufbringen auf das Trägerelement 10 ihre Endeigenschaften besitzen, beispielsweise Pasten, die ein gesintertes Material enthalten. Die Herstellung der siebdruckfähigen Keramikpaste ermöglicht es, beliebige Strukturen auf das Material des Trägerelements 10 zu drucken und diese thermisch und mechanisch an das Material des Trägerelements 10 anzubinden.The printable paste can be designed as a metal oxide-ceramic powder mixture with an NTC characteristic. Since the paste is not yet sintered when applied to the carrier element, the material of the
Durch die Verwendung des Trägerelements als Substrat, auf das die temperaturabhängige Widerstandsschicht aufgebracht wird, weist das temperaturempfindliche elektrische Bauelement eine hohe mechanische Stabilität auf. Des Weiteren besitzt das elektrische Bauelement eine hohe thermische Wärmeleitfähigkeit und gewährleistet zugleich eine elektrische Isolation zwischen dem Material der Widerstandsschicht 20 und einem Untergrund, auf den das Trägerelement 10 aufgebracht wird.By using the carrier element as a substrate onto which the temperature-dependent resistance layer is applied, the temperature-sensitive electrical component has a high level of mechanical stability. Furthermore, the electrical component has a high level of thermal conductivity and at the same time ensures electrical insulation between the material of the
