Problems solved by technology

[0003] The main part of the touch screen is a resistive film layer that is very compatible with the surface of the display screen. It uses a layer of glass or hard plastic plate as the base layer, and the surface is coated with a transparent conductive coating. The material of the conductive coating is generally ITO (Indium Oxide) ), but ITO is easily damaged before use. After being applied on the base layer, it is easy to cause the capacitive screen to fail to work normally, and it needs to be reworked or even scrapped directly.
It is necessary to test the conductivity of the circuit board using the ITO film. Currently, the hand-held probe is used to identify it. Due to the uneven force applied by the operator due to the manual test, sometimes there will be excessive force, which will damage the circuit board and increase cost of production

Embodiment Construction

[0018] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0019] Such as figure 1 , figure 2 , image 3 As shown, a probe fixture includes a base 1 and a support platform 2 disposed on the base 1. A clamping plate 3 is installed on the support platform 2, and at least one clamping hole 4 is opened on the clamping plate 3.

[0020] In the present invention, the clamping plate 3 is preferably arranged vertically. The clamping plate 3 is provided with two clamping holes 4 along the longitudinal direction. The two clamping holes 4 are located on the same straight line, and two probes can be clamped at one time, which improves the efficiency of the test. .

[0021] In order to avoid the movement of t...

Abstract

The invention relates to a probe jig. The probe jig comprises a base and a supporting table arranged on the base. A clamping plate is arranged on the supporting table, and at least one clamping hole is formed in the clamping plate. According to the probe jig, a probe can be clamped stably through the clamping hole in the clamping plate, and meanwhile the probe can be fixed on a working table through an installation hole and a fixing hole and can not shake in the process of testing. The probe jig is high in testing accuracy and improves work efficiency.

Description

technical field [0001] The invention relates to a probe fixture, in particular to a probe fixture for utilizing the conductivity of a circuit board of an ITO thin film. Background technique [0002] Touch screen (TP, Touch Panel) is an inductive liquid crystal display device that can receive input signals such as contacts. When the image button on the screen is touched, the tactile feedback system on the screen can drive various The connection device can produce vivid audio-visual effects through the liquid crystal display screen, and is widely used in tablet computers, PDAs, smart phones, air conditioners, refrigerators and other fields. [0003] The main part of the touch screen is a resistive film layer that is very compatible with the surface of the display screen. It uses a layer of glass or hard plastic plate as the base layer, and the surface is coated with a transparent conductive coating. The material of the conductive coating is generally ITO (Indium Oxide) ), but...
