Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor integrated circuit manufacturing and relates to a fixing frame of a packaging substrate. Background Art

[0002] IC package substrates are gradually evolving towards thinner thicknesses, finer circuits, and higher integration densities. Package substrate production can be categorized into dry and wet lines based on process characteristics. Wet lines are further divided into horizontal and vertical wet lines. Horizontal wet lines primarily utilize rollers for transmission, and the package substrates inevitably come into contact with the rollers during production. Vertical wet lines, on the other hand, utilize a frame and grippers to secure the package substrates, which are then moved by a transmission mechanism. This minimizes contact with the substrate surface during production, significantly improving yield. However, as package substrates become thinner, the requirements for the grippers in vertical lines are becoming increasingly stringent. If the gripper pressure is too low, there is a risk of the board falling out of place. If the gripper pressure is too high, the board edge will inevitably be damaged, especially in thin board production, where this damage is particularly severe. Small robotic arms currently exist on the market, but these are not practical because the frames and grippers are frequently exposed to various chemicals during production and require frequent disassembly and maintenance. Furthermore, robotic arms are often costly.

[0056] The utility model provides a fixing frame for packaging substrate. Figure 1 , which is a structural diagram of a fixing frame of a package substrate of the present invention. The fixing frame of the package substrate includes a frame 1 and a substrate clamp 2 fixed on the frame 1. Figure 2 , which is a structural schematic diagram of the substrate clamping jaw 2 of the present invention, wherein the substrate clamping jaw 2 includes a lower jaw, an upper jaw, a first adjusting screw 204, a first nut 205, a second adjusting screw 211, a second nut 212, a compression spring 215, a fixed bottom block 203, a round rod fixing block 207 and a round rod 214, wherein the lower jaw is arranged opposite to the upper jaw, and the lower jaw includes a lower jaw baffle 201 and a lower jaw clamping tooth 202 connected in sequence.

[0057] As an example, see Figure 3 , which is a structural diagram of the upper claw, the upper claw includes an upper claw baffle 208, an arched connecting block 210 and an upper claw clamping tooth 209 connected in sequence.

[0058] Specifically, such as Figure 2 and Figure 3 As shown, a first screw hole is provided in the lower claw baffle 201, a second screw hole is provided in the upper claw baffle 208, and first through holes 213 are provided at both ends of the arched connecting block 210; the first adjusting screw 204 passes through the first screw hole from the side of the lower claw baffle 201 facing away from the upper claw and is threadedly connected to the first nut 205; the second adjusting screw 211 passes through the second screw hole from the side of the upper claw baffle 208 facing away from the lower claw and is threadedly connected to the second nut 212; the compression spring 215 is located between the lower claw baffle 201 and the upper claw baffle 208, and the compression spring One end of the spring 215 is fixed on the first nut 205, and the other end of the compression spring 2215 is fixed on the second nut 212; the fixed bottom block 203 is fixedly connected to the opposite sides of the lower claw and is fixedly connected to the frame 1 through bolts 206; the round rod fixing block 207 is arranged on the opposite sides of the arch connecting block 210 and is fixedly connected to the fixed bottom block 203, and a second through hole matching the first through hole 213 is provided in the round rod fixing block 207; the round rod 214 passes through the first through hole 213 and the second through hole and is connected to the round rod fixing block 207.

[0059] Specifically, when an external force acts on the upper claw baffle 208 and the lower claw baffle 201, the compression spring 215 is further compressed, and the external force drives the upper claw to rotate around the round rod 214, so that the upper claw teeth 209 are separated from the lower claw teeth 202, and the packaging substrate is placed between the upper claw teeth 209 and the lower claw teeth 202. The external force is removed, and the compression spring 215 is in a compressed state, squeezing the upper claw baffle 208 of the upper claw to drive the upper claw to rotate around the round rod 214, so that the upper claw teeth 209 and the lower claw teeth 202 are in contact with the packaging substrate, thereby fixing the packaging substrate.

[0060] Specifically, during use, the pressure exerted by the upper jaw teeth 209 and the lower jaw teeth 202 on the packaging substrate can be adjusted by rotating the first adjusting screw 204. When the thickness and weight of the packaging substrate increase, the first adjusting screw 204 is rotated to increase the length of the first adjusting screw 204 passing through the lower jaw baffle 201, driving the first nut 205 to move in a direction that reduces the length of the compression spring 215, increasing the elastic force of the compression spring 215, and thereby increasing the pressure exerted by the upper jaw teeth 209 and the lower jaw teeth 202 on the packaging substrate. When the thickness of the packaging substrate decreases and the pressure it can withstand is lower, the first adjusting screw 204 is rotated to decrease the length of the first adjusting screw 204 passing through the lower jaw baffle 201, driving the first nut 205 to move in a direction that increases the length of the compression spring 215, reducing the elastic force of the compression spring 215, and thereby reducing the pressure exerted by the upper jaw teeth 209 and the lower jaw teeth 202 on the packaging substrate. Similarly, rotating the second adjusting screw 211 can also adjust the pressure of the upper jaw clamping teeth 209 and the lower jaw clamping teeth 202 on the packaging substrate (ie, adjust the pressure of the substrate clamping teeth 2).

[0061] As an example, the number of the lower claw teeth 202 is one or more, and the number of the upper claw teeth 209 is one or more. The upper claw teeth 209 correspond one to one with the lower claw teeth 202. The more the upper claw teeth 209 and the lower claw teeth 202, the more stable the fixing effect on the packaging substrate. The number of the upper claw teeth 209 and the lower claw teeth 202 can be set according to the specific situation. In this embodiment, two upper claw teeth 209 and two lower claw teeth 202 are used.

[0062] As an example, there are multiple upper claw teeth 209 , and a fixing plate 216 arranged in the transverse direction is installed between two adjacent upper claw teeth 209 . The fixing plate 216 can further reinforce the upper claw teeth 209 .

[0063] As an example, a buffer pad is provided on the lower claw clamping teeth 202, and a buffer pad is provided on the upper claw clamping teeth 209. The upper claw clamping teeth 209 and the lower claw clamping teeth 202 directly contact the surface of the packaging substrate during operation. The provision of a buffer pad can better protect the packaging substrate and prevent the upper claw clamping teeth 209 and the lower claw clamping teeth 202 from causing damage to the packaging substrate when fixing the packaging substrate, such as causing damage to the packaging substrate and leaving clamping marks on the surface of the packaging substrate.

[0064] As an example, the lower jaw baffle 201 is in a rectangular, trapezoidal or semi-elliptical shape, and the upper jaw baffle 208 is in a rectangular, trapezoidal or semi-elliptical shape. The specific shape can be determined according to the specific situation to facilitate the use of the substrate clamp 2.

[0065] As an example, the length of the first adjusting screw 204 is greater than the thickness of the lower claw baffle 202, and the length of the second adjusting screw 211 is greater than the thickness of the upper claw baffle 208, so that the first adjusting screw 204 and the second adjusting screw 211 have adjustable space.

[0066] As an example, the screw rod of the first adjusting screw 204 is marked with a first scale, and the screw rod of the second adjusting screw 211 is marked with a second scale. The pressure range of the substrate clamp 2 is tested by a pressure sensor, and the relationship between the length of the first adjusting screw 204 passing through the lower jaw baffle 201 and the pressure of the substrate clamp 2 is obtained. A corresponding first scale (not marked in the figure) is set on the screw rod of the first adjusting screw 204. Similarly, the pressure range of the substrate clamp 2 is tested by a pressure sensor, and the relationship between the length of the second adjusting screw 211 passing through the upper jaw baffle 208 and the pressure of the substrate clamp 2 is obtained. A corresponding second scale (not marked in the figure) is set on the threaded rod of the second adjusting screw 211. The values of the first scale and the second scale can reflect the corresponding pressure values, so that the substrate clamp 2 can effectively adjust the pressure according to the thickness of the packaging substrate.

[0067] As an example, see Figure 4 , which shows a schematic structural diagram of the compression spring 215 of the present invention, shows that the first nut 205 has a first protrusion 217 that penetrates into the compression spring 215 on its contact surface with the compression spring 215, and the second nut 212 has a second protrusion 218 that penetrates into the compression spring 215 on its contact surface with the compression spring 215. The first protrusion 217 and the second protrusion 218 better secure the compression spring 215, preventing it from popping out of the substrate clamp 2 due to prolonged pressure.

[0068] As an example, the number of the substrate clamps 2 is at least four, ensuring that the four corners of the package substrate are fixed by the substrate clamps 2 to prevent the package substrate from falling off due to external force during transportation.

[0069] As an example, the plurality of substrate clamps 2 are symmetrically distributed at the upper and lower ends of the frame 1 to ensure that the force points of the package substrate are uniform and to better prevent the package substrate from being affected by other external forces during movement.

[0070] Specifically, in this embodiment, in order to be applicable to a corrosive environment, such as an acidic environment, the substrate clamping jaws 2 are made of a corrosion-resistant alloy, such as an iron-based alloy and a nickel-based alloy.

[0071] In summary, the utility model provides a fixing frame for a packaging substrate, comprising a frame and a substrate clamp fixed on the frame, wherein the substrate clamp comprises a lower jaw and an upper jaw arranged relatively to each other, a compression spring, a fixed bottom block, a round rod fixing block and a round rod, the lower jaw comprises a lower jaw baffle and a lower jaw clamping tooth connected in sequence, a first adjusting screw passes through the lower jaw baffle and is connected to the first nut, the upper jaw comprises an upper jaw baffle, an arched connecting block and an upper jaw clamping tooth connected in sequence, a second adjusting screw passes through the upper jaw baffle and is connected to the second nut, the first nut and the second nut are located between the lower jaw baffle and the upper jaw baffle, the two ends of the compression spring are fixed on the first nut and the second nut respectively, the fixed bottom block is located on both sides of the lower jaw and is fixedly connected to the frame, the round rod fixing blocks are located at both ends of the arched connecting block and are fixedly connected to the fixed bottom block, and the round rod passes through both ends of the arched connecting block and is connected to the round rod fixing block.
