Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor packaging, and in particular to a product inspection auxiliary tool and method. Background Art

[0002] The development of the integrated circuit industry has gradually formed a pattern of coordinated development of integrated circuit design, integrated circuit manufacturing and integrated circuit packaging and testing. In the integrated circuit packaging and testing industry, integrated circuit packaging technology is a process of connecting and fixing the chip to the carrier substrate, leading out the pins and plastic-sealing it into an integral power device or module. It mainly plays the role of connecting the internal and external circuits of the chip, fixing, sealing, protecting the chip and dissipating the heat of the chip. The core-on process is the core process of integrated circuit packaging technology. The quality of the core-on process directly determines the performance and reliability of the entire chip after packaging. In the flip-chip core-on process, taking the commonly used packaging form SOT563 product as an example, one card is two boxes of products, each box contains 20 lead frames, and each lead frame has 960 products. Three products from each box need to be randomly selected on the three-light machine for appearance inspection. In order to ensure that abnormal products can be 100% inspected, product visual inspection is particularly important before the three-light machine inspection. The purpose of visual inspection is to quickly lock abnormal products so that they can be 100% inspected on the three-light machine. The operator visually inspects the products in the entire box to find products with obvious abnormalities (chip sticking, empty sticking, waste chips, frame deformation, etc.), and then 100% of the abnormal products found by visual inspection are inspected by three-light machines and the abnormal products are disposed of to prevent the abnormal products from escaping to the next process. During the visual inspection process, the operator holds the box in his hand and performs visual inspection in a standing position under the light. During this process, because the box has to be held by hand, the box often falls or the products are scattered, causing the entire box of products to be scrapped.

[0003] At present, in order to prevent the whole box of products from falling during the visual inspection, the operator is required to place the material box on the inspection table, and use a flashlight to half-squat and look at the material box with both eyes for visual inspection. Although this effectively prevents the risk of the whole box of products falling during the visual inspection, the frame defects cannot be clearly detected due to the inspection angle. In addition, since the operator half-squats for a long time, he may hold the inspection table when he stands up, which may cause the material box to fall over, and it is not ergonomic. Therefore, it is very important to design a product inspection tool that allows operators to inspect products while sitting, which can quickly detect abnormal products and eliminate the risk of products falling or scattering, and the inspection posture is ergonomic.

[0004] The present invention provides a product inspection auxiliary tool and method. The inspection tool consists of a mounting plate, a material box carrying platform, a rotating mechanism, etc., and can carry a whole box of products. The auxiliary tool can be equipped with a light source. The product can be rotated to a certain angle by manually rotating the material box carrying platform, so that an operator can quickly perform visual inspection of the whole box of products at different angles in a sitting manner.

[0041] See also Figure 1 The present invention provides a product inspection auxiliary tool, including a mounting plate 1, a material box supporting platform 2 and a connecting component 3.

[0042] One end of the material box supporting platform 2 is movably connected to the mounting plate 1 . The material box supporting platform 2 is used to place the material box 7 . The material box supporting platform 2 and the mounting plate 1 are connected via a connecting component 3 .

[0043] A handle 4 is provided at one end of the material box supporting platform 2 away from the connecting assembly 3 .

[0044] The product inspection auxiliary tool provided in this embodiment only needs to place the material box 7 containing the product 8 on the material box supporting platform 2 when in use. The material box supporting platform 2 is open in design, and the inspector can use the handle 4 to rotate the free end of the material box supporting platform 2 around the connecting component 3 to adapt to the heights of inspectors of different heights. The tool is easy to operate, and the inspector can inspect the product while sitting. It can not only quickly detect abnormal products and eliminate the risk of products falling or scattering, but also the inspection posture is ergonomic, saving time and effort.

[0045] Optionally, the product inspection auxiliary tool also includes a light source, which is used to provide sufficient lighting.

[0046] Optionally, the light source may be a lighting lamp 6 (such as Figure 1 , Figure 2 As shown), the irradiation lamp 6 is arranged on the mounting plate 1, and the light of the irradiation lamp 6 is directed to the free end of the material box supporting platform 2, so that it is easy to clearly observe whether the product 8 placed in the material box 7 has any flaws or defects during inspection.

[0047] Optionally, the light source may also be an LED panel light 9 (such as Figure 3 As shown), the LED panel light 9 is arranged at the fixed end of the material box supporting platform 2, and the light of the LED panel light 9 is emitted from the fixed end of the material box supporting platform 2 to the free end of the material box supporting platform 2.

[0048] Specifically, when the LED panel light 9 is selected, in order to obtain sufficient light, the LED panel light 9 can be directly attached to the end of the material box supporting platform 2, such as Figure 3 The size of the LED panel light 9 is adapted to the end of the material box support platform 2, so that it is both beautiful and has the best lighting effect.

[0049] Optionally, a gas spring 5 is connected to the outer wall of the material box support platform 2, one end of the gas spring 5 is fixed to the mounting plate 1 close to the connecting component 3, and the other end of the gas spring 5 is fixed to the material box support platform 2 away from the connecting component 3.

[0050] like Figure 1-Figure 3 As shown, a gas spring 5 is connected to the outer wall of the material box support platform 2, the purpose of which is to reduce the force of the arm rotating the tool and relieve arm fatigue. Without the gas spring 5, the user will feel tired after rotating the material box support platform 2 with the material box 7 placed thereon by the handle 4 for a long time, thereby affecting work efficiency. By providing the gas spring 5, the user can significantly reduce fatigue, and work efficiency can be higher and easier.

[0051] Optionally, if the light source is an LED panel light 9, the product inspection auxiliary tool should also include a controller 11 and a cylinder 10. The controller 11 is electrically connected to the cylinder 10 and the LED panel light 9 respectively.

[0052] like Figure 3 As shown, the cylinder 10 is fixed to the outside of the right side wall of the material box carrier 2, and the material box carrier 2 is provided with a window corresponding to the position of the cylinder 10, and the output end of the cylinder 10 extends into the material box carrier 2 through the window. In order to place and remove the material box 7 more quickly, there should be a gap between the material box 7 and the two side walls of the material box carrier 2, so when the material box carrier 2 is rotated for detection, the material box 7 will be displaced along with the rotation of the material box carrier 2, and the material box 7 can be clamped by setting the cylinder 10.

[0053] The controller 11 is provided with a first switch 12 and a second switch 13, and the first switch 12 and the second switch 13 are used to control the operation of the cylinder 10 and the LED panel light 9, respectively. In this embodiment, a three-way solenoid valve is installed in the controller 11, the air inlet end of the three-way solenoid valve is connected to the external compressed air, and the two air outlet ends of the three-way solenoid valve are connected to the cylinder 10 through a hose.

The back plate 203 is arranged at the left end of the side plate 202. The top end of the back plate 203 is flush with the top of the left end of the side plate 202. A top plate 204 is arranged between the top of the back plate 203 and the top of the left end of the side plate 202.

[0055] There is a gap between the material box and the side plate 202 , the height of the side plate 202 exceeds the height of the material box, and the length of the bottom plate 201 exceeds the length of the material box.

[0056] If the light source can be selected from the illumination lamp 6, a hollow 205 can also be provided on the back plate 203, such as Figure 1 As shown, the light from the illumination lamp 6 can be emitted through the hollow 205 . In order to improve the utilization rate of the light source, a reflector (not shown in the figure) can be arranged outside the hollow 205 .

[0057] Optionally, the connecting component 3 includes a fixed seat, a bearing and a connecting shaft. The two fixed seats are fixed on the mounting plate 1 at intervals, each fixed seat is provided with a bearing, and connecting shafts are respectively installed on both sides of the material box support platform 2, and the connecting shafts are respectively connected to the bearings.

[0060] In step 1, the target position is related to the height of the inspector. Normally, the inspector sits for inspection, and the target position is generally a position where the height of the movable end of the material box support platform 2 is flush with the line of sight.

[0061] Step 2: Provide sufficient lighting conditions for inspection of the product 8 in the material box through a light source.

[0062] Step 3: Inspect the products 8 placed in the material box 7 one by one, mark the defective products or remember the positions of the defective products until all products 8 are inspected.

[0063] Step 4: After the inspection is completed, hold the handle 4 to reset the material box support platform 2 and take out the material box 7.
