Temperature tester based on film type temperature sensor and its manufacture method

Abstract

The invention relates to a temperature tester based on a film type temperature sensor and a manufacturing method, comprising: a cylinder outer protection tube, wherein a first space and a second space are formed by concaving inwards on the upper part and the lower part along the length direction and connected together through a via hole; a film type temperature sensor, arranged in the inner of the outer protection tube through the first space, the second space and the via hole; and fillings, filled in the first space and the second space of the outer protection tube, to fix the film type temperature sensor in the inner of a first protection tube and a second protection tube to become an integer. According to the invention, the film type temperature sensor in the space of the outer protection tube is processed by the filled fillings or ceramic paste based on the temperature tester of the film type temperature sensor, and the pins of the sensor and the wire connecting parts can be fixed stably. Outer connecting metal wires at the lower space are fixed stably through the fillings, therefore, outer mechanical impact is effectively prevented to the film type temperature sensor through the outer connecting metal wires at the lower part.

Description

technical field [0001] The invention relates to a temperature tester based on a thin-film temperature sensor and a manufacturing method thereof, especially by treating the thin-film temperature sensor in the space of an external protection tube with a filling material or ceramic ointment, which can stabilize The sensor pin and the wire connection part are firmly fixed; the metal wire for external connection in the lower space is stably fixed by the filler, and the temperature tester based on the thin film temperature sensor and its manufacturing method are made to have good mechanical shock resistance . Background technique [0002] A prior art film type temperature sensor will be described below. [0003] FIG. 1 is a diagram of a general thin-film temperature sensor in the prior art. As shown in FIG. 1 , a metal substance is used to form a thin film on a thin ceramic substrate with a length of about 10 mm and a thickness of less than 1 mm, and pattern it to form a thin fi...
