Problems solved by technology

[0003] Aiming at the problem that it takes a long time to remove the sealing cap of the existing TO-46 sensor chip, and its internal structure is easily damaged, which is not conducive to the effective analysis of the cause of the failure. The present invention provides a TO-46 sensor chip. Open the cover and fix the fixture, which can effectively fix the TO-46 sensor chip, and then cooperate with the existing cutting tool to cut the TO-46 sensor chip layer by layer, so as to ensure that its internal structure is not damaged and reduce It is more conducive to analyze the original cause of adverse effects

Embodiment Construction

[0010] Such as figure 1 As shown, a TO-46 sensor chip opening and fixing fixture includes a fixing base 1 and a base 2, and the lower end of the fixing base 1 is movably installed inside the base 2. Specifically, the lower end of the fixing base 1 is provided with an external thread, and the upper end of the base 2 is provided with an internal thread matching the external thread. The fixed seat 1 is connected to the base 2 through threads. A flange 11 is provided along the outer periphery of the upper end of the fixing seat 1, and a radial socket 12 is provided on the surface of the flange 11, and the socket 12 is matched with the pins of the TO-46 sensor chip, and a gap is also provided on the flange 11 13. The notch 13 corresponds to the protruding part of the sealing cap of the TO-46 sensor chip.

[0011] Preferably, external threads are provided on the outside of the lower end of the base 2 .

[0012] The working principle of the present invention is: the pin of TO-46 s...

Abstract

The invention provides an uncovering fixing clamp for a TO-46 sensing chip, the fixing clamp can effectively fix the TO-46 sensing chip and then perform layer-by-layer scribing and cutting on the TO-46 sensing chip in cooperation with an existing cutting tool, so that the internal structure of the TO-46 sensing chip can be prevented from being damaged, the influence of external causes is reduced,and the analysis of original adverse causes of the TO-46 sensing chip is facilitated. The uncovering fixing clamp comprises a fixed seat and a base and is characterized in that the lower end of the fixed seat is movably arranged in the base, a flange is arranged along the periphery of the upper end of the fixed seat, a radial jack is arranged on the surface of the flange, the jack is matched witha pin of a TO-46 sensor chip, and a notch is also arranged on the flange. And the notch corresponds to a convex part of a sealing cap of the TO-46 sensing chip.

Description

technical field [0001] The invention relates to the technical field of fixtures for sensor chips, in particular to a cover-opening and fixing fixture for TO-46 sensor chips. Background technique [0002] The TO-46 sensor chip will produce some defective parts during the manufacturing process. In order to analyze the cause of the defect, it is usually necessary to remove the TO-46 sealing cap, and then use auxiliary testing equipment to test the inside of the disassembled chip. analyze. When the existing TO-46 sensor chip removes the cap, the operator uses one hand to hold the cap of the TO-46 sensor chip, and the other hand uses a special cutting tool to place the cap on the chip. Carry out cutting and separation, but with this removal method, because the TO-46 sensor chip is small and difficult to fix, it takes a long time to cut, and it is easy to damage the internal structure of the TO-46 sensor chip, which is not conducive to the detection of bad reasons. effective ana...
