[0002] If the chip fault is not discovered during chip testing, the cost of discovering the fault at the circuit board (PCB) level is ten times that of the chip level. Therefore, the higher the level and the smaller the process, the higher the requirement for the yield rate during the detection process, so the test probe plays a very important role.

[0003] However, the lower probes of the conventional chip test probe socket are exposed, and the probes are prone to twisting and deformation during operation, and even damage to the probe card, which can lead to errors or failures in chip detection. In addition, the lever arm used to control the lifting of the upper end cover in the conventional probe test socket is a fragile device and cannot be replaced. The above problems can easily lead to problems such as low yield and high detection costs during probe detection. Therefore, the development of a new probe test socket is imminent.

[0050] The guide mechanism 6 includes a fixed plate 28, an intermediate plate 29 and an upper follower plate 30, which are fixed on the device body 1 in sequence from the lower follower plate 4 to the upper end cover 2. The fixed plate 28, the intermediate plate 29 and the upper follower plate 30 are all provided with holes 31 matching the probe 7, and the holes 31 form a mesh structure. A fork on one side of the detection upper end is arranged in each mesh. The detection end of the probe 7 passes through the holes 31 on the fixed plate 28, the intermediate plate 29 and the upper follower plate 30 respectively. The holes 31 on the fixed plate 28, the intermediate plate 29 and the upper follower plate 30 are arranged at an angle to facilitate the detection end of the probe 7 to move closer or apart. After the chip is detected, the position of the protection plate 3 can be adjusted manually and the protrusion 9 is adjusted to the top of the protection plate 3, that is, the protrusion 9 is misaligned with the through groove 10.

[0051] Example 2: Example 2 is the test method of Example 1, specifically: Fig.14 As shown, a method for using the chip test probe socket with a probe protection function as described above,

[0052] S1. Hold the chip on both sides and place it in the groove of the upper end cover 2, and fix it on the device body 1 through the fixing clip of the fixing mechanism 5, so that each pin of the chip to be tested is accurately inserted into the fork of the upper half of the probe 7;

[0053] S2. Apply downward pressure to the upper end cover 2. The X-shaped lifting structure composed of the left force arm 22 and the right force arm 23 is under pressure. The upper end cover 2 moves downward and drives the lower follower plate 4 to move synchronously. The probe 7 on the lower follower plate 4 moves downward on the guide mechanism 6. Therefore, the part of the probe 7 located above the guide mechanism 6 moves downward so that the upper half of the probe 7 is tightened and clamps the pin of the detection chip when it is displaced in the hole 31, thereby preparing for chip detection. At the same time, during the downward pressing process of the upper end cover 2, the protrusion 9 in the track column 14 is driven by the slider column in the upper end cover 2 to move downward. When the protrusion 9 moves in the limiting section 11 of the slide groove 8, the protection plate 3 moves downward synchronously with the probe 7.

[0054] S3. When the upper end cover 2 is pressed downward to the limit, the protrusion 9 enters the reset section 13 from the limit section 11 through the guide section 12, and the protrusion 9 corresponds to the through groove 10. At this time, the protection plate 3 loses the downward pressure of the protrusion 9, and the protection plate 3 moves upward to the initial position under the action of the first reset mechanism, that is, the spring between the moving groove 19 and the moving block 20 drives the protection plate 3 to move upward to the initial position, so that the connection end of the probe 7 passes through the through hole 301 on the protection plate 3 and is inserted into the external device to realize the detection of the chip;

[0055] S4, cancel the downward pressure applied to the upper end cover 2, and the upper end cover 2 moves up to the initial position under the action of the second reset mechanism, that is, the X-shaped lifting structure composed of the left force arm 22 and the right force arm 23 restores the initial state so that the upper end cover 2 moves up to the initial position. During the upward movement of the upper end cover 2, the probe 7 fixed on the lower slave plate 4 moves upward accordingly, so that the upper half of the bifurcation of the probe 7 is opened because it is higher than the guide mechanism 6, thereby releasing the chip pins, and at the same time canceling the fixing of the fixed clip to the detection chip;

[0056] S5, taking out the detected chip on the device body 1.

[0057] The above-mentioned ideal embodiments of the present invention are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the technical idea of ​​the present invention.
