Uncovering fixing clamp for TO-46 sensing chip

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...
