Embodiment Construction

[0032] now according to figure 1 , a preferred embodiment of the manufacturing method according to the present invention will be explained in more detail. As shown in step S100 , assuming the temperature sensor as described in FIG. 3 , the wire 108 of the temperature sensor is partially subjected to a reduction process to at least partially remove the oxide layer 112 . In step S102, the sensor is first immersed in the degreasing bath, and then in step S104, the sensor is immersed in the rinse bath I. After rinsing or cleaning, the sensor is immersed in the activator bath in step S106, and then in the rinse bath II in step S108. Then, the sensor is immersed in a currentless gold plating bath in step S110, followed by immersing the sensor in rinse bath III in step S112.

[0033]After step S112 , as shown in FIG. 2 , the sensor has at least partially gold-plated wires. In FIG. 2 , elements already described with reference to FIG. 3 have the same reference numerals. As mention...

Abstract

The invention provides a method for producing a temperature measuring sensor, which comprises at least one connection wire (108) made of a non-precious metal or of an alloy containing a non-precious metal, a connection wire (108) is first fixed to the temperature measuring sensor. An oxide layer (112) is removed from at least one section of the connection wire (108) and, immediately after the removal of the oxide layer, the at least one section (114) of the connection wire (108) is chemically gold plated.

Description

technical field [0001] The invention relates to a method for manufacturing a temperature sensor, in particular to a method of using a wire made of a non-noble metal and / or an alloy comprising a non-noble metal which has been at least partially electroless or gold-plated (for example by currentless gold plating method). Background technique [0002] Temperature sensors using thin-film technology (eg platinum temperature sensors) have been manufactured in different designs and have been used for many years for precise temperature measurement tasks. [0003] Fig. 3 shows a known temperature sensor, while Fig. 3(a) shows a cross-sectional view of the temperature sensor, and Fig. 3(b) shows a top view of the temperature sensor. A platinum film 102 with a thickness of about 1 μm is coated on the AL 2 o 3 on a ceramic carrier 100. The platinum film 102 is structured to include, for example, 100Ω resistive traces. In order to protect the platinum film 102, a suitable protective...
