Description
TECHNICAL FIELD
[0001] The utility model relates to chip detection technical field especially relates to a wafer chip batch turnover device. BACKGROUND
[0002] In the field of semiconductor manufacturing and packaging testing, wafer chips (Die) are usually produced in the form of wafers (Wafer). In order to facilitate transportation, storage and subsequent automated processing, the cut wafer chips will be placed in a special bearing tray, such as a waffle pack, a gel-pak chip packaging gel box, etc. Among them, waffle box is widely used because of its simple structure and low cost. The waffle box includes a tray and a cover plate, and the tray is provided with a plurality of fixed grids, each fixed grid corresponding to a chip.
[0003] For flip-chip, the bumps (Bump) are usually located at the bottom of the chip. When the chip is inspected, the Bump needs to be turned up to observe the topography, size and other parameters of the Bump; while in SMT (Surface Mount Technology) patching, the Bump needs to be turned down to connect with the pads on the PCB (Printed Circuit Board). Therefore, between chip inspection and patching, the chips in the waffle box often need to be turned over in batches.
[0004] In the traditional way, the chips are turned over manually one by one by the operator, or turned over with the help of simple tools (such as tweezers, suction pen, etc.). This way is inefficient and easy to cause damage to the chip.
[0005] The existing simple device turns over, such as the turnover device disclosed in Chinese patent publication No. CN217306464U, which includes a turnover plate and two trays. The two trays are pressed together through the limiting hole on the turnover plate to realize the turnover of the chip. But after the chip is turned over by this device, it is taken out for detection and then put in again. Since the tray has no positioning means, it cannot guarantee that the chip and the groove on the tray correspond one by one, there is a defect, and it cannot realize the free conversion between the bump up and down.
[0006] Therefore, it is necessary to improve the existing wafer chip turnover technology to overcome the defects of the prior art. UTILITY MODEL CONTENT
[0007] In order to overcome the problems in the related art, the purpose of the utility model is to provide a wafer chip batch turnover device to solve the technical problems of low efficiency and easy damage of manual turnover of chips in the prior art, and the chip positioning after turnover is not accurate in the existing simple turnover device, and the free conversion cannot be realized.

[0069] The first bearing part 100 has a first accommodating surface 110, and one or more first accommodating parts 111 are arranged on the first accommodating surface 110. The first accommodating part 111 is a groove structure, and the shape and size of the groove are matched with the outer shape of a wafer chip bearing tray (such as a wafer box tray), so that the bearing tray can be stably accommodated therein. On both sides of the first accommodating part 111, an open slot 300 is arranged for facilitating the operator to take and place the wafer box tray.400
[0070] The second bearing part 200 has a second accommodating surface 210, on which one or more second accommodating parts 211 are arranged.

The first bearing member 100 and the second bearing member 200 are both frame structures and are made of anti-static materials, such as anti-static polycarbonate (PC) or anti-static polyether ether ketone (PEEK).
[0082] The first bearing member 100 has a first accommodating surface 110, and a first accommodating part 111 is arranged on the first accommodating surface 110. The first accommodating part 111 is a hollow area in the frame, which is slightly larger than the shape and size of a wafer chip bearing tray (such as a waffle box tray) and can allow the waffle box tray to pass through the hollow area. On the inner side edge of the first bearing member 100, a protrusion or elastic buckle is arranged to fix the waffle box tray in the first accommodating part 111 when the turnover device is closed.
[0083] The second bearing member 200 has a second accommodating surface 210, and a second accommodating part 211 is arranged on the second accommodating surface 210. The second accommodating part 211 is also a hollow area in the frame, which corresponds to the shape and size of the first accommodating part 111. When the first bearing member 100 and the second bearing member 200 are closed, the first accommodating part 111 and the second accommodating part 211 jointly form a space for fixing the waffle box tray. On the inner side edge of the second bearing member 200, a protrusion or elastic buckle is arranged to cooperate with the positioning structure on the first bearing member 100 when the turnover device is closed.
[0084] The first bearing member 100 and the second bearing member 200 are connected by a hinge. The hinge is arranged on one side edge of the first bearing member 100 and the second bearing member 200, so that the two bearing members can be opened and closed like a book.
[0085] On the other side edge (opposite to the hinge) of the first bearing member 100 and the second bearing member 200, a locking mechanism is arranged. The locking mechanism is a magnetic buckle, which comprises a magnet and an iron sheet (or two magnets) arranged on the first bearing member 100 and the second bearing member 200, respectively. When the turnover device is closed, the magnetic buckle can attract the two bearing members together and keep the closed state.
[0086] The following describes the operation process of the wafer chip batch turnover device of the embodiment:
[0087] 1. Open the turnover device, and open the first bearing part 100 and the second bearing part 200 along the hinge.
[0088] 2. Place the chip bearing tray, and place the wafer box tray loaded with the chips to be turned over in the first accommodating part 111 (the hollowed-out area) of the first bearing part 100, so that the edge of the wafer box tray is in contact with the protrusion or elastic buckle on the inner side of the first bearing part 100.
[0089] 3. Fold the turnover device: rotate the second bearing part 200 along the hinge to fold with the first bearing part 100. At this time, the second accommodating part 211 on the second bearing part 200 and the first accommodating part 111 together form a space, and the wafer box tray is clamped in the middle. At the same time, the positioning structure on the second bearing part 200 cooperates with the positioning structure of the first bearing part 100 to ensure that the tray is fixed, and the magnetic buckle attracts the two bearing parts together.
[0090] 4. Turn over: manually turn over the entire device by 180 degrees. The chips fall from one wafer box tray to another wafer box tray under the action of gravity.
[0091] 5. Open the turnover device, and slightly force the magnetic buckle to open, and open the first bearing part 100 and the second bearing part 200 along the hinge.
[0092] 6. Take out the chip bearing tray, and take out the wafer box tray that has completed the turnover.
[0093] The wafer chip batch turnover device of the embodiment adopts two frame structure bearing parts connected by a hinge, which is convenient to open and close and easy to operate. The hollowed-out area in the frame serves as an accommodating part. The positioning structure of the protrusion or elastic buckle can fix the wafer box tray in the accommodating part to prevent the tray from moving or falling off during the turnover process. The locking mechanism of the magnetic buckle makes the device more stable in the folded state, ensuring the reliability of the turnover process.
