Description

Needle Implantation Machine

This invention is about a needle implantation machine, and in particular, refers to an automated needle implantation device that can more accurately and quickly implant a test probe, with the needle implantation machine being the primary application of the invention in order to improve the convenience and effectiveness of needle implantation.

In the semiconductor industry, electrical tests are required for integrated circuit (IC) chips on wafers that have completed the initial process to ensure that the chip circuits can operate normally and meet product requirements. At the same time, the product yield rate can be improved to achieve the effect of improving production capacity.

The current traditional testing method is to place the IC chip in the IC tester, and then use the IC test socket and the printed circuit board to test whether the electrical properties of the IC chip can operate normally. The current IC test socket is to set probe holes corresponding to the IC chip on a substrate, and then implant the probes into these probe holes so that the probes can be in electrical contact with the electrical connection terminals or die contact pads of the components on the IC chip to test and detect the electrical properties of the IC chip. However, the probes carried in the above IC test socket must be implanted manually, and the personnel can only pick up one probe at a time during the implantation operation, which is time-consuming and labor-intensive.

In order to improve the above-mentioned deficiencies, a needle loading device and a needle loading method were developed as disclosed in the invention patent No. I333399, wherein the needle loading device comprises: at least one needle loading fixture, a vacuum element, a needle loading platform, a pin needle transmission element and an air flow supply element, wherein the needle loading fixture comprises: a needle box having a first surface and an opposite second surface, wherein the needle box has a plurality of through holes passing through the first surface and the second surface of the needle box; and an air chamber, which is arranged on the second surface of the needle box and has a vacuum end, so that the needle loading is promoted by the suction force of the vacuum end. The patent mainly utilizes a shaking method to allow the carrier needle to slide into the carrier needle hole through the guidance of the guide angle, thereby eliminating the cost of visual inspection and replenishing missing needles, improving the degree of automation, shortening the production cycle, and avoiding missing needle defects caused by human error.

However, the circuit design of each IC chip is different, and not every probe hole needs to be implanted with a probe. Therefore, it is not possible to implant the probe by shaking. In addition, during the shaking process, the probe holes set on the substrate or the edge chamfers of the through-holes set on the board are likely to interfere with each other, and may even overlap with other probe holes (or through-holes), thereby affecting the accuracy and smoothness of the implantation. Therefore, the implantation is still inconvenient and slow in practice.

Today, the creators, in the spirit of continuous improvement and based on their rich design, development and actual manufacturing experience in the relevant industry for many years, have specially provided a needle implanting machine in the hope of achieving the purpose of better practical value.

The main purpose of this creation is to provide a needle implantation machine, especially an automated needle implantation device that can more accurately and quickly implant a test probe, so as to improve the convenience and efficiency of needle implantation.

At the same time, the implantation position is monitored and confirmed by the image positioning unit, so that in addition to achieving automated needle implantation, it also has the advantages and functions of convenience, speed and high implantation accuracy.

A preferred embodiment of the needle implanting machine of the present invention further includes a positioning unit, which is arranged corresponding to the discharge port of the vibration plate, and the positioning unit is used to limit the forward transportation of the probe to cooperate with the movement of the suction unit to clamp it.

In a preferred embodiment of the needle implanting machine of the present invention, a groove is provided on one side of the discharge channel of the vibration plate, and a blowing unit is installed, wherein the blowing unit is used to blow the probes with the wrong conveying direction into the vibration plate.

In order to make the technical content, purpose and effect of this creation more complete and clear, we explain it in detail below. Please also refer to the disclosed diagrams and figure numbers:

First, please refer to the first picture, which is a three-dimensional schematic diagram of the needle implantation machine of this invention, which mainly includes:

A vibrating plate (1) is provided with a discharge channel (11) for conveying a probe (A) so as to guide the probe to a discharge port (12) of the discharge channel (11) for positioning;

A first moving mechanism (2) is a transfer mechanism including first, second and third linear axial displacements and a rotational axial displacement, and a suction unit (3) is installed in the rotational axis, and the suction unit (3) is corresponding to the probe (A) at the discharge port (12) of the vibration plate (1);

An image positioning unit (6) is correspondingly arranged above the test seat carrier (5) to monitor and confirm the position of the probe (A) implanted by the suction unit (3) by taking an image of the test seat (B).

Please refer to the first to seventh figures. In actual use and implementation, the main action flow of the invention is controlled by an automatic control unit [not shown in the figure]. That is, the vibration plate (1), the suction unit (3), the first moving mechanism (2), the second moving mechanism (4) and the image positioning unit (6) are all connected to and controlled by the automatic control unit; a plurality of probes (A) are placed in the vibration plate (1), and the probes (A) are continuously transported toward the discharge channel (11) through vibration transport, and the discharge channel (11) of the vibration plate (1) is connected to the image positioning unit (6). 11), an image recognition unit (7) is further installed above the vibrating plate (1), and the image recognition unit (7) is mainly used to photograph the probe (A) transported on the discharge channel (11) and determine the transport direction of the head and tail of the probe (A) [as shown in the first and second figures]. In addition, as shown in the second and eighth figures, a groove (111) is provided on one side of the discharge channel (11) of the vibrating plate (1), and a blowing unit (8) is installed, and the blowing unit (8) is used to blow the probe (A) with the wrong transport direction into the vibrating plate (1), so that it is vibrated and transported forward again.

When the probe (A) is transported to the discharge port (12) of the discharge channel (11), a positioning unit (9) is provided at the discharge port (12) to limit the forward transport of the probe (A). Furthermore, the positioning unit (9) adopts a sucking piece, through which the probe (A) is sucked and positioned at the discharge port (12) to wait for being sucked. At this time, a test seat (B) is placed on the test seat carrier (5) on the second moving mechanism (4). The test seat (B) has a plurality of sockets for the probe (A) to be implanted, and the implantation position of the probe (A) is set according to the chip to be tested.

Next, the suction unit (3) is displaced to the discharge port (12) through the first, second, and third linear axes of the first moving mechanism (2) [such as the X axis (left-right displacement), the Y axis (front-back displacement), and the Z axis (up-down displacement)], and the probe (A) corresponding to the suction discharge port (12) is rotated and displaced through the rotation axis [such as the A axis] [the sucking piece releases the probe (A), as shown in the third figure], and then the first moving mechanism (2) brings the probe (A) to the test seat carrier (5) so that the probe (A) adsorbed by the suction unit (3) is implanted in the The test seat (B) on the test seat carrier (5); however, the automatic control unit can calculate according to the relative positions of the test seat (B) and the probe (A) absorbed by the absorption unit (3) to obtain the shortest displacement, and at the same time, the first moving mechanism (2) drives the absorption unit (3), and the second moving mechanism (4) drives the first and second linear axes [such as X-axis (left-right displacement), Y-axis (forward-backward displacement)] to move the test seat carrier (5) to the corresponding implantation point [as shown in Figures 6 to 7], so as to save the movement time and effectively shorten the operation time.

Finally, the image positioning unit (6) is used to capture an image of the test seat (B) of the implanted probe (A) to monitor and confirm the position of the implanted probe (A) by the suction unit (3) to ensure that the implantation is correct.

In addition to the above-mentioned implementations of the first and second moving mechanisms (2) and (4), another best implementation example is listed below and described as follows:

The first moving mechanism (2) is provided with at least one linear axial displacement and one rotational axial displacement mechanism, and the at least one linear axial displacement is preferably a vertical displacement of the Z-axis linear axial. In this implementation state, the first moving mechanism (2) is arranged adjacent to the discharge port (12) of the discharge channel (11) of the vibrating plate (1), so that the suction unit (3) in the rotational axis direction is subjected to rotational displacement. The probe (A) at the suction outlet (12) can correspond to the probe (A). In this way, the linear X-axis displacement of the left and right and the linear Y-axis displacement of the front and back can be omitted. The first moving mechanism (2) with up and down displacement and rotational displacement is used in conjunction with the linear X-axis displacement of the left and right and the linear Y-axis displacement of the front and back of the second moving mechanism (4) to perform needle implantation, which can save movement time and effectively shorten the operation time.
