Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that the prior art lacks a needle seat insertion reverse test device for detecting whether the needle seat is inserted backwards, and can only rely on manual checking of the needle seat insertion, resulting in low detection accuracy, poor detection efficiency and detection cost high problem

Embodiment 1

[0038] This embodiment provides a kind of ICT tester, and the top plate of ICT tester is provided with such as figure 1 and figure 2 The needle socket insertion test device shown is used to measure whether the needle socket on the circuit board placed on the carrier board is reversed. Most of the needle sockets 1 applied on the circuit board have The upper step 2 with a higher height and the lower step 3 with a lower height are located on the lower step 3 for the pins used to connect with the socket.

[0039] Such as Figure 1 to Figure 3 As shown, the needle socket reverse test device includes:

[0040]The switch-type pressure piece 4 is set on the top plate of the ICT tester and is driven by the top plate to move toward the carrier board. The conductive member 6, the first conductive member 5 and the second conductive member 6 of the cylindrical structure apply their separate biasing force to the two through the spring so that the gap between the first conductive member ...

Embodiment 2

[0047] The difference between this embodiment and embodiment 1 is that, as image 3 As shown, the protective sleeve 9 sleeved on the second conductive member 6, the side of the protective sleeve 9 facing the needle holder 1 is a pointed structure that avoids the pins located on the upper step 2 of the needle holder 1 . Setting the protective cover 9 on the second conductive member 6 as a sharp point can effectively prevent the problem that the protective cover 9 contacts the contact pins and damages the contact pins during the use of the needle socket reverse test device.

Embodiment 3

[0049] The difference between this embodiment and Embodiment 1 is that the first conductive member 5 and the second conductive member 6 are sleeved with protective sleeves 9 on the sides away from each other, and are respectively arranged on the first conductive An outer protective sheath 15 for covering the connecting part of the first conductive element 5 and the second conductive element 6 is also arranged between the two protective sheaths 9 on the element 5 and the second conductive element 6 . The outer protective cover 15 is used to prevent other components from touching the connection position of the first conductive member and the second conductive member to affect the accuracy of the resistance measured by the test circuit, thereby affecting the measurement results of the reverse pin socket insertion test device.

Abstract

The invention discloses a reverse insertion testing device of a pin socket, an ICT tester and using method thereof. A height difference is formed between an upper step and a lower step of a to-be-tested pin base. The reverse insertion testing device comprises a switching type pressing element and a testing circuit. A first conductive element and a second conductive element that are arranged at anadjustable interval are arranged inside the switching type pressing element; the switching type pressing element has a disconnection state and a connection state; and the lower step abutted against the pin base, the first conductive element and the second conductive element are separated in the disconnection state and the upper step abutted against the pin base, the first conductive element and the second conductive element are connected in the connection state. The testing circuit is used for testing resistance values between a first end and a second end when the switching type pressing element is in a connection state and a disconnection state. The reverse insertion testing device is used for monitoring the pin base automatically; and problems that detection efficiency is low, the troubleshooting accuracy is low, and the troubleshooting cost is high because the operator needs to check the circuit boards one by one due to lack of a testing device for testing whether the pin base is inserted reversely on the circuit board can be solved.

Description

technical field [0001] The invention relates to the technical field of test fixtures, in particular to a needle socket reverse test device, an ICT tester and a method for using the same. Background technique [0002] With the continuous development of electronic technology, electronic products are constantly enriching our lives, and the circuit board is the most important part of it. Whether the electronic components on the circuit board can be installed correctly directly affects the quality of electronic equipment. As a common electrical component on the circuit board, the needle holder is easy to reverse the step direction of the needle holder when plugged into the surface of the circuit board, causing the position of the pin to shift. If there is a problem of reverse insertion, it will affect the performance of similar printed boards. Consistency prevents sockets and needle sockets from being inserted through automated equipment, and even changes the arrangement of elect...
