Embodiment Construction

[0060] For purposes of illustrating the invention, figure 1 A cross-section of a base body 1 is shown with a conductive coating 3 suitable for soldering applied to its outer insulating surface. For example, the base body 1 consists entirely of an insulating material, in particular a ceramic material (in particular aluminum oxide) or an insulating plastic or the like. Alternatively, the base body 1 can also consist of an electrically conductive material provided with an insulating layer on the outside, for example metal coated with an insulating layer.

[0061] A spatially restricted connection point 5 is arranged on the coating 3 of the base body 1 , via which connection point 5 a connecting element (not shown here) is connected to the coating 3 by means of an electrically conductive solder joint.

[0062] According to the invention, a recess 7 is provided in the base body 1 which at least partially surrounds the connection point 5 on the outside. The groove 7 is formed as a...

Abstract

The invention relates to a method for soldering a connection element (55) at a connection location (5, 41, 41', 45, 45', 49, 49a, 49b) on an electrically conductive, soft-solderable coating (3, 39, 39', 43, 43', 47) of an insulating surface of a main body (1, 5, 13) with a soft soldering method and to sensors produced using this method, with which method and sensors the wetting of the coating (3, 39, 39', 43, 43', 47) with soft solder (9) that takes place during the soft soldering process is spatially delimited, in that a groove (7, 57, 59) is provided in the main body (1, 13), said groove at least partially surrounding the connection location (5, 41, 41', 45, 45', 49, 49a, 49b) on the outside, at least one part-face, which encloses the connection location (5, 41, 41', 45, 45', 49, 49a, 49b), of the outer insulating surface of the main body (1, 13) is coated with the coating (3, 39, 39', 43, 43', 47), soft solder (9) is applied locally to the connection location (5, 41, 41', 45, 45', 49, 49a, 49b), and the connection element (55) is soldered at the connection location (5, 41, 41', 45, 45', 49, 49a, 49b) in a soft soldering process by means of the applied soft solder (9).

Description

technical field [0001] The invention relates to a method for soldering connecting elements at the connection points using a soldering method to an electrically conductive coating suitable for soldering applied to an insulating outer surface of a base body, and to manufacturing sensor. Background technique [0002] Such a method can be used in particular in the manufacture of sensors, such as capacitive ceramic pressure sensors, in order to obtain an electrically conductive connection between a connection part or an electrically conductive sensor shield, wherein the connection part is between the sensor and a measuring electrode or a reference potential . [0003] An example of a capacitive ceramic pressure sensor is described in DE 10 2008 054 879 A1. It consists of a ceramic substrate, a pressure-sensitive measuring membrane connected to the substrate to form a measuring chamber, and an electromechanical transducer. The electromechanical transducer transforms the pressur...
