Description

Fixable probes and probe fixing components

technical field

The present invention relates to a probe fixing assembly for fixing a probe when inspecting a display device and a probe conforming to the probe fixing assembly.

Background technique

In general, a probing device includes a plurality of probes that contact contact pads formed on a display device. Recently, the intervals between contact pads of a display device, that is, pitches (pitch) are formed very narrowly, and efforts are being made to make Various researches and developments for accurately positioning probes on contact pads.

If a plurality of probes are closely spaced and cannot maintain a fixed position, even if they are slightly moved or tilted, adjacent probes will contact each other and short-circuit, or exceed the contact position of the display device, resulting in a problem that accurate inspection cannot be performed.

Therefore, when inspecting a display device, it is very important to accurately inspect the display device by fixing the probe so that the probe does not move up and down or left and right but maintains its position.

As an example, a boss 210 may be formed on one side thereof so that the probe 100 can be inserted. The shape of the probe holder 200 can be variously designed as long as the probe 100 can be placed and fixed.

The movement prevention part 300 functions to prevent the movement of the probe 100 from the probe holder 200 in the up-down direction and in the left-right direction. Therefore, even if a force is applied when inspecting the display device, the probe 100 can be accurately inspected because it is fixed at its position.

The wandering prevention part 300 includes a first wandering prevention part 310 and a second wandering prevention part 320 .

The first wandering preventing portion 310 functions to prevent the probe 100 from wandering in the left-right direction. That is, by preventing the adjacent probes 100 from wandering in the left and right directions, it is possible to prevent a short circuit between the probes when inspecting the display device, and to enable accurate inspection.

The second movement prevention part 320 functions to prevent movement of the probe 100 in the vertical direction. That is, if one end of the probe 100 touches the circuit pattern of the display device, a force is applied to the probe 100 to swim up and down. If this process is repeated, the probe 100 is deformed, so the second movement prevention part 320 makes the probe 100 is fixed in the vertical and horizontal directions, preventing the probe 100 from moving up and down, and further preventing the probe 100 from being deformed.

The probe fixing assembly of the present invention further includes a probe main body 400 , and the second anti-swimming part 320 is fixedly combined with the probe main body 400 . The second anti-swimming part 320 placed on the probe body 400 can be fixedly combined with various connecting means such as screws and bolts.

On the other hand, as shown in FIG. 3, FIG. 5 and FIG. 6, an insertion protrusion 140 is formed on one side of the probe 100, and the first wandering prevention part 310 includes a thin film 330 formed with an insertion hole 330a for inserting the protrusion. Up to 140 can be inserted.

If a plurality of probes 100 are formed at predetermined intervals, the number of insertion holes 330 a formed on the film 330 is also formed corresponding to the number of probes 100 , and the shape of the insertion holes 330 a is preferably a shape corresponding to the shape of the insertion protrusion 140 form.

As shown in FIGS. 3 and 4 , the probe 100 may include a first horizontal portion 110 , a vertical portion 120 , and a second horizontal portion 130 .

The first horizontal portion 110 is formed long in the horizontal direction so that one end thereof can contact the circuit pattern of the display device, the vertical portion 120 is formed vertically at the other end of the first horizontal portion 110 , and the second horizontal portion 130 is formed at the vertical portion 120. The other end of the first horizontal portion 110 is extended and formed in a direction opposite to the first horizontal portion 110 .

The bottom of the first horizontal part 110 is placed on the probe base 200 , one side of the vertical part 120 is placed on a side of the probe base 200 , and the bottom of the second horizontal part 130 is placed on the bottom of the probe base 200 . Schematically, the probe holder 200 has an "L"-shaped cross section, and the probe 100 is formed in a structure that can be placed according to the shape of the probe holder 200 .

At this time, a slit may be formed in the probe holder 200 , and when the slit is formed, the first horizontal portion 110 and the second horizontal portion 130 are inserted into the slit.

The insertion protrusion 140 includes a first insertion protrusion 142 protrudingly formed at the vertical portion 120, a second insertion protrusion 144 protrudingly formed at the second horizontal portion 130, and the film 330 includes an insertion hole 330a formed therein so that the first insertion protrusion The first film 332 into which the protrusion 142 can be inserted, and the second film 334 formed with an insertion hole 330a so that the second insertion protrusion 144 can be inserted.

In order to prevent the first film 332 from being separated from the first insertion protrusion 142 , preferably, a locking protrusion 142 a protrudes from the upper end of the first insertion protrusion 142 . In addition, it is preferable to form both ends of the first insertion protrusion 142 and the second insertion protrusion 144 obliquely, so that the first film 332 and the first insertion protrusion 142, and the second film 334 and the second insertion protrusion 144 are easily formed. combination between.

In addition, the upper ends of the first insertion protrusion 142 and the second insertion protrusion 144 are preferably formed flat so that the second movement prevention part 320 can be in surface contact, and it is preferable to utilize the second movement by ensuring a wide contact area as much as possible. The prevention part 320 prevents the probe 100 from moving up and down. More preferably, an elastic portion 144 a is formed on the second insertion protrusion 144 so that the second insertion protrusion 144 can be prevented from being damaged due to excessive pressure by the second movement preventing portion 320 .

The second anti-swimming part 320 is fixedly combined with the probe body 400 in the vertical and horizontal directions, so that the first insertion protrusion 142 and the second insertion protrusion 144 can firmly contact the second anti-swimming part 320 .

When the display device is inspected using the probe 100, one end of the probe 100 contacts a circuit pattern of the display device, and the other end thereof contacts a circuit pattern connected to the inspection control device. The plurality of probes 100 should contact the circuit pattern without omission, and the first horizontal portion 110 and the second horizontal portion 130 of the probe 100 are preferably elastically deformable in order to abut the contact terminals of the probes 100 . In particular, it is preferable to form an open-loop hole 132 in the second horizontal portion 130 to maximize the elastic force.

In order to compare the effect of the present invention, the present inventors measured the contact position error between the prior art to which the anti-swimming part 300 is not applied and the present invention. The contact positions of probes No. 1 to No. 100 were measured, and the error values thereof are summarized in Table 1 below.

【Table 1】

As shown in Table 1, the test results show that when the anti-swimming part 300 is not applied, the average error value is 9.46 μm, and the average error value of the present invention is 4.87 μm. That is, it can be seen that according to the present invention, the average error value is reduced to 1/2 level compared with the prior art.
