The chip type ceramic sensor is formed by overlapping a plurality of layers of ceramic substrates which are distributed with different electrode shapes and have cavity structures, internal electrodes need to be led out through holes among the layers and are distributed at the tail end pin part of the chip type ceramic sensor, and in the testing process of various chip type sensor ceramic chip cores, the electrodes at the tail end pin part of the chip core need to be led out through leads and are connected with testing equipment.
However, because the ceramic core needs a certain working temperature (100-. The traditional packaging method is to fix the size of a sensor core and the position of a pin electrode, and a test fixture used in a laboratory needs different packaging fixtures due to the fact that the size of the pin position of the electrode is uncertain and the research on the design and the function of the sensor core is different because a ceramic substrate shrinks in the preparation process of a chip. Experimenters need to design and fabricate different packaging fixtures to meet the requirements of testing, which prolongs the development time of the sensor.
Therefore, it is very necessary to provide a universal package fixture for testing a sheet sensor used in a laboratory.
