Abstract

A test probe cleaning device, its clamping member and test base relate to the technical field of semiconductors. The present invention aims to solve the existing problems of how to effectively replace manual cleaning and how to thoroughly clean the probe. A test probe cleaning device, comprising a cleaning member, a clamping member, a test socket, a test base and a test probe; a clamping member is arranged above the cleaning member, and a test socket is arranged below the cleaning member, the The test socket is installed on the test base, and the clamping member can control the cleaning member above the test socket through the movement of the transmission mechanical arm, so that the cleaning member can move into the test socket and stick to the probe of the test probe in the test socket. close against. The invention solves the existing problems of how to effectively replace manual cleaning and how to thoroughly clean the probe, thereby effectively replacing manual cleaning, while ensuring cleaning quality and testing efficiency.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a test probe cleaning device, a clamping member and a test base thereof. Background technique [0002] The last process of semiconductor manufacturing is testing. The testing process can be divided into preliminary testing and final testing. Its main purpose is not only to find defects in semiconductor components, but also to classify semiconductor components according to specifications. In the process of testing a semiconductor component such as a chip, the probe will make electrical contact with the pins on the semiconductor component, such as solder balls, to test the relevant electrical properties of the semiconductor component and evaluate whether its function is normal. The solder balls on the bottom surface of the chip are made of metal materials. During the repeated testing process, after the tip of the probe repeatedly touches the solder balls, metal oxides and ot...
