Problems solved by technology

[0003] The existing test method is mainly for the operator to use the four-wire test pen to measure. The strength of the operator, the contact point of the test pen, the contact angle and the personal operating habits all have certain randomness, which leads to the inaccuracy of the test.

Abstract

The invention discloses a fixture for ensuring accuracy of tests on chip-type ultra-low resistance product. The fixture comprises a base, the base is provided with a limit station and a bearing platform arranged side by side with the limit station, and the limit station is provided with the bearing platform of the same size with the limit station. The bearing platform is hollow, one side of the bearing platform is provided with upper and lower stop bolts, and the interior is provided with a spring. The top end of the bearing platform is provided with a connecting arm. One end of the connecting arm extends into the bearing platform and is connected with the bearing platform, and the other end of the connecting arm is provided with a probe carrying sheet. One side of the probe carrying sheet is provided with a four-wire probe. The fixture for ensuring accuracy of tests on chip-type ultra-low resistance product avoids the test inaccuracy caused by human factors such as test habits, intensity, and test point locations.

Description

technical field [0001] The invention belongs to a fixture for testing the accuracy of chip-type ultra-low resistance products. Background technique [0002] In recent years, due to the development of small-volume, high-precision and low-resistance products, as well as the substantial improvement of data acquisition and processor performance, this situation has led to technological innovations in the traditional current detection method based on the shunt principle, and has made the new Apps are constantly evolving. In the production and use of chip ultra-low resistance products, inspection, screening and testing of ultra-low resistance are often involved. However, because the resistance value of ultra-low resistance products is too small, operators often have inaccurate tests during the test process, large differences in repeated tests, and large differences in test data from different inspectors. How to solve these problems must start from the characteristics of the produ...
