Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects in the existing method for detecting probe wear and provide a new method for detecting probe wear. The technical problem to be solved is to solve the needs of the current method for detecting probe wear It takes a lot of time and is easy to cause misjudgment, and the current probe is too small or stained with dirt or tin to cause the difficulty of judgment to increase, and the increase in test costs and Test can reduce problems such as, very suitable for practical

Abstract

The invention relates to a method for detecting probe wear and a probe, in particular to a method for online real-time detecting probe wear, the probe and the manufacturing method of the probe. The probe comprises: a probe main body, which comprises at least one needle head; a detecting layer, which coats the needle head or the whole probe main body; and an impact-resistant layer, which is formed on the detecting layer and coats the detecting layer, in order to increase the degree of impact resistance of the probe. The detecting layer with eye-catching color is manufactured inside the probe, which leads the detecting layer of the probe to be exposed after the probe wears, while, the eye-catching color of the probe at the detecting layer serves as a mark, therefore, the online personnel can easily and instantly judge whether the probe wears.

Description

technical field [0001] The invention relates to a method and a probe for detecting wear of a probe, in particular to a method and a probe which are simple, not easy to misjudgment, and can detect the wear of the probe in real time online. Background technique [0002] After the electronic components are manufactured, they usually need to go through circuit probetest, which is used to distinguish the good and bad of the chips before packaging, confirm the quality of the chips for packaging, and avoid the bad quality of the chips caused by packaging. Necessary waste. After packaging, a final test is required to ensure that the chip is not damaged during the packaging process and that the chip still meets the specification after packaging. However, regardless of the above-mentioned tests, the probes are required to be used as electrical connections between the electronic components and the test machine to transmit test signals during the test. [0003] Generally speaking, in ...
