Abstract

The invention provides a probe needle sleeve punching tool, which comprises a main body for fixing a single positioning member, and a plurality of positioning members, wherein each of the plurality ofpositioning members has a first cavity for accommodating a probe needle sleeve to extend therein, and depths of the first cavities are different; and the main body forms detachable connection with each of the positioning member. Compared with the prior art, the probe needle sleeve punching tool can be used for punching out probe needle sleeves with different height requirements, and the punched probe needle sleeves are uniform in height and stable. Since threads on the main body are removed, the contact area between fastening screws and the main body is enlarged, so that the connection between the positioning members and the main body is more stable and not prone to loosen; and in the process of using the probe needle sleeve punching tool, force receiving portions are an annular top surface of a first column and an annular bottom surface of a positioning portion, and the fastening screws and the main body cannot be damaged due to knocking, so that the connection between the positioning members and the main body is stable and durable.

Description

technical field [0001] The invention belongs to the technical field of circuit board detection, and in particular relates to a probe needle sleeve punching tool. Background technique [0002] In the circuit board inspection industry, test probes (also called spring probes) and test probe needle sleeves are commonly used materials to connect circuit boards and test equipment. Standard test probes have two specifications according to their strokes, which we call them. High needle (long working stroke 9.3mm) and low needle (standard working stroke 4.3mm), the test probe needle sleeves are of uniform specifications, suitable for high needle and low needle; conventional circuit board testing methods are ICT (circuit) testing, FCT (function) test, the corresponding carrier is called ICT fixture and FCT fixture. At present, there are mature IFCT tests in the industry, which integrate the two parts of ICT and FCT, and realize two kinds of tests on one test fixture. In order to achi...
