Abstract

The invention relates to a test auxiliary tool, in particular to an NTC thermistor chip screening test auxiliary tool with a surface electrode. The technical problem to be solved is to provide an auxiliary tool for screening and testing NTC thermistor chips with surface electrodes, wherein the auxiliary tool is high in working efficiency and does not need excessive operation of workers. The invention provides an auxiliary tool for screening and testing the NTC thermistor chip with the surface electrode. The tool comprises a base, a first mounting plate, mounted at the right upper part of the base, and a through hole being formed in the left side of the first mounting plate; a multimeter, mounted at the left upper part of the base; a bearing seat, mounted at the top of the first mounting plate; reels, mounted on the front side and the rear side of the bearing seat; and torsional springs, arranged between the reels and the bearing seats. When the NTC thermistor chip is detected, the clamping block can fix the NTC thermistor chip in the placing frame, so that the NTC thermistor chip is prevented from moving during detection.

Description

technical field [0001] The invention relates to a testing auxiliary tooling, in particular to an NTC thermistor chip screening testing auxiliary tooling with surface electrodes. Background technique [0002] A more obvious characteristic of NTC thermistor is that its resistance will decrease exponentially with the increase of temperature. Due to this characteristic, NTC thermistor chips will be used in many temperature-related environments to achieve its purpose of usage. [0003] After the production of the NTC thermistor chip with surface electrodes is completed, it needs to be tested to see if there is any quality problem. The common detection method is normal temperature detection. Usually, after the NTC thermistor chip is placed by the staff, Use the detection pen on the multimeter to press the two corners of the NTC thermistor chip, and then check the reading on the multimeter. If the reading is within the normal range, the quality of the NTC thermistor chip is good. ...
