Description

[0001] The present application is a divisional application of the application No.202510608112.3, filed on May 13, 2025, and entitled "Exposure device for integrated circuit carrier PCB". TECHNICAL FIELD

[0002] The application belongs to the technical field of exposure devices, in particular to an exposure device for an integrated circuit carrier PCB. BACKGROUND

[0003] The integrated circuit carrier PCB is a high-precision printed circuit board specially designed for carrying and connecting integrated circuit chips, mainly used in semiconductor packaging, chip testing, system integration and other scenes. It is a key carrier for connecting chips and external circuits in the integrated circuit industry chain, and its design and process directly affect the electrical performance, reliability and heat dissipation capacity of the chip. The essence of PCB exposure is to transfer the mask pattern to the photosensitive material layer on the surface of the copper-clad plate through ultraviolet light irradiation, and to form a resist pattern through photochemical reaction. The core step is to expose the photosensitive material layer that has been pasted or coated on the surface of the copper-clad plate to achieve the purpose of pattern transfer.

[0004] The photosensitive material is generally divided into dry film and wet film. The pasting of dry film and copper-clad plate is a key process of PCB pattern transfer, which directly affects the accuracy and circuit quality of subsequent exposure and development.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0038] As Figures 1 to 7 shown, the integrated circuit carrier PCB board exposure device of the embodiment of the present application comprises a shell 1, the inside of the shell 1 is provided with a placement plate 2, the upper part of the placement plate 2 is provided with a matching plate 8, the inside of the shell 1 is configured with a main roller assembly 4 and a pre-roller assembly 5 for roller pressing of the PCB board and the dry film, and the adjusting assembly 6 for improving the lamination quality of the copper-clad plate and the dry film is configured between the main roller assembly 4 and the pre-roller assembly 5.

[0039] The adjusting assembly 6 comprises a two-way air cylinder 601, the left and right sides of the two-way air cylinder 601 are fixedly connected with adjusting rods 602, one end of the adjusting rod 602 is rotatably clamped with a cutting piece 603, one side of the cutting piece 603 is spline-connected with a driving motor 604, the side close to the driving motor 604 of the cutting piece 603 is rotatably clamped with a matching sleeve 607, the surface of the matching sleeve 607 is fixedly connected with an arc rod 608, one end of the arc rod 608 is fixedly connected with a limiting strip 609, the front of the limiting strip 609 is provided with a guide plate 613, the guide plate 613 is rotatably connected with the matching plate 8 through a pin shaft, and a compression spring is arranged between the guide plate 613 and the limiting strip 609.

[0040] The present application considers that before the integrated circuit carrier PCB is exposed, the surface of the copper-clad plate needs to be attached with a dry film, and when the copper-clad plate and the dry film are rolled, a large number of bubbles may be generated between the copper-clad plate and the dry film, although most of the bubbles can be discharged through the pre-rolling of the pre-rolling assembly 5 and the formal rolling of the main rolling assembly 4, but the bubbles may be left at the edge position, which may affect the subsequent exposure and development steps, cause circuit defects, reduce the quality of the integrated circuit carrier PCB exposure, and because the size of the dry film attached to the surface of the copper-clad plate is larger than the size of the plate itself, and has a certain viscosity, when the dry film is placed on the surface of the copper-clad plate, the remaining dry film will extend out from the edge position on both sides of the copper-clad plate, when the dry film and the copper-clad plate are rolled and attached, in order to ensure the accuracy of the attachment position, the side of the plate is generally limited, but after limiting the plate and the film, the remaining dry film will stick to the side of the copper-clad plate, when the dry film and the copper-clad plate are rolled to discharge bubbles, at this time the two sides of the plate are equivalent to being "sealed" by the dry film, at this time the bubbles cannot be discharged quickly from the two sides of the plate, causing a large number of bubbles to remain between the copper-clad plate and the dry film in a small state after formal rolling, affecting the quality of subsequent exposure and development, therefore, first start the bidirectional air cylinder 601 to drive the adjusting rod 602 to extend and retract through the output end, the movement of the adjusting rod 602 can drive the cutting piece 603 to move inside the cooperation plate 8, so as to adjust the position of the cutting piece 603, and then place the copper-clad plate and the dry film above the placing plate 2, insert the two sides into the sliding groove inside the cooperation plate 8, which can limit the two sides of the plate and the film, and facilitate the rolling and attachment of the two;

[0041] When the plate and the film are inserted into the sliding groove inside the matching plate 8, the pre-rolling assembly 5 is started to transport the film and the plate, and the driving motor 604 drives the cutting piece 603 to rotate. When the film passes the position of the cutting piece 603, the cutting piece 603 can cut the excess part of the dry film edge to avoid the bubbles not being discharged in time when the film and the plate are rolled. It should be noted that when the cutting piece 603 is adjusted in position, the cutting piece 603 will move the matching sleeve 607 and the arc rod 608, and the movement of the arc rod 608 will drive the limiting strip 609 to move inside the matching plate 8. When one side of the film is being cut, if the film accumulates more and more inside the matching plate 8, when the cut film accumulates to a certain extent, it will be wound on the surface of the cutting piece 603, which not only affects the normal cutting of the cutting piece 603, but also affects the position accuracy of the film on the surface of the plate. At this time, the end of the limiting strip 609 close to the cutting piece 603 is tapered, and after the edge of the film is cut, the cut film edge will continue to move backward along the inner side of the taper tip of the limiting strip 609. At the same time, the limiting strip 609 can "distribute" the cut film and the film that needs to be rolled, preventing the cut film from affecting the position accuracy of the uncut film on the surface of the copper-clad plate. Moreover, since the edge of the film has been cut, when the film continues to move backward, the edge of the film will always be in contact with the inner side of the limiting strip 609, thereby improving the stability of the film on the surface of the plate and avoiding the position deviation of the film and the copper-clad plate during rolling.

[0042] It should be noted again that by opening the discharge groove inside the matching plate 8, since the dry film has a certain hardness before being rolled, after the film is cut, the cut film will first contact one side of the guide plate 613, thereby being guided by the surface of the guide plate 613 into the discharge groove and discharged from the discharge groove. This can avoid the cut film accumulating inside the matching plate 8, affecting the normal cutting of the film by the cutting piece 603. Moreover, since the guide plate 613 and the limiting strip 609 are provided with a top spring in the middle, when the limiting strip 609 is adjusted in position inside the matching plate 8, it will move one end of the top spring, and after the one end of the top spring is moved under stress, the other end will exert pressure or release pressure on the guide plate 613. When the excess cut of the dry film is wide, the limiting strip 609 will be closer to the position of the film inside the matching plate 8, and the angle between the guide plate 613 and the matching plate 8 will be larger under the action of the tension spring, facilitating the guidance of the cut film and making the film discharged from the discharge groove. This can effectively improve the bubble discharge effect of the dry film and the copper-clad plate when they are rolled, thereby improving the effect of subsequent exposure and development of the copper-clad plate.

[0043] As Figures 8 to 10As shown, the surface of the adjusting rod 602 is fixedly connected with a fixed cylinder 605, the front of the fixed cylinder 605 is slidingly matched with a matched rod 606, the surface of the matched rod 606 is slidingly connected with a top plate 9, the upper end of the matched rod 606 is fixedly connected with a transmission plate 611, the front end of the transmission plate 611 is fixedly connected with a connecting rod 10, the lower side of the connecting rod 10 is rotatably connected with a rotating sleeve 11, the inside of the rotating sleeve 11 is fixedly connected with a second extrusion roller 502, and the surface of the connecting rod 10 is slidingly connected with a connecting plate 12.

[0044] The present application also considers that when the dry film of different sizes is left cutting, although the size of the edge of the dry film can be adjusted by adjusting the position of the cutting piece 603, when the size of the cutting is increased, the contact area between the film and the plate is increased due to the increase of the size of the film, at this time, the bubbles are more likely to be generated, and if the force of the second extrusion roller 502 on the film is not changed, the effect of the pre-rolling will be reduced, not only the number of edge bubbles will be increased, but also the bubbles in the middle position will be left over before the formal extrusion, therefore, by arranging the pre-rolling assembly 5 in the inside of the shell 1, when the film and the plate are inserted into the two sides of the matched plate 8 and are transmitted to the rear by the pre-rolling assembly 5, at this time, the plate and the film will move from the lower side of the second extrusion roller 502, at this time, the rotation of the second extrusion roller 502 can pre-roll the film and the plate, most of the bubbles can be extruded and discharged before the formal rolling of the film and the plate, and the quality of the formal rolling is improved;

[0045] It should be noted that when the size of the film is increased, in order to avoid that the two sides of the film can be fully attached to the two sides of the plate during the formal rolling, at this time, the amount of the film reserved on the two sides will also be increased, at this time, the two-way air cylinder 601 is started to drive the cutting piece 603 at one end of the adjusting rod 602 to move outward, at this time, the movement of the adjusting rod 602 can drive the fixed cylinder 605 to move, the movement of the fixed cylinder 605 can drive the matched rod 606 to move downward in the inside of the top plate 9 through the cooperation of the inclined block in the inside of the fixed cylinder 605 and the inclined groove in the matched rod 606, the downward movement of the matched rod 606 can drive the transmission plate 611 above to move, the movement of the transmission plate 611 can drive the rotating sleeve 11 below the connecting rod 10 to move, at this time, the movement of the rotating sleeve 11 can drive the second extrusion roller 502 to press downward above the film, thereby improving the pre-rolling force of the second extrusion roller 502 on the film, thereby improving the effect of the pre-rolling of the film, avoiding that a large number of bubbles are finally affected after the quality of the completed attachment during the formal rolling;

[0046] It needs to be emphasized again that since the position of the cutting piece 603 inside the matching plate 8 is only slightly adjusted, the fixed cylinder 605 moves the matching rod 606 up and down by a "short distance" through the inclined block, and does not make the matching rod 606 move the transmission plate 611 by a long distance, which can effectively avoid the second extrusion roller 502 from exerting a large pressure on the film, thereby affecting the pre-rolling effect between the film and the plate and causing damage to the film itself. When cutting a film with a small size, the pressure of the second extrusion roller 502 on the film will decrease, and since the contact area between the film and the plate becomes smaller, the bubble generation rate will decrease, and a larger force is not needed to easily extrude the bubbles, which can effectively improve the pre-rolling effect, make the adjustment assembly 6 and the pre-rolling assembly 5 linked, and accurately control the force used for pre-rolling the film when cutting the film with a remaining size, thereby fully improving the effect of the film and the plate.

[0047] As shown in Figures 2 to 3 The main roller assembly 4 includes a first conveying roller 401, and a first extrusion roller 402 is arranged below the first conveying roller 401. The rear of the main roller assembly 4 is configured with a cooling machine 3 for cooling the film and the copper-clad plate after roller pressing and bonding.

[0048] When the film and the plate are inserted into the inside of the matching plate 8, the second conveying roller 501 is driven to rotate by the motor to convey the plate below, thereby moving the film below the second extrusion roller 502 to realize pre-rolling of the film and the plate. After pre-rolling is completed, the second conveying roller 501 continues to convey the plate to the upper side of the first conveying roller 401. The first conveying roller 401 is driven to rotate by the motor to continue conveying the plate and the film, and the first extrusion roller 402 is also driven to rotate by the motor. The film and the plate can complete the roller pressing and bonding work under the cooperation of the first conveying roller 401 and the first extrusion roller 402, which can effectively improve the bonding efficiency between the two. After roller pressing and bonding, the first conveying roller 401 continues to drive the film and the plate after roller pressing to move backward, and the cooling machine 3 is started to generate cold air to cool them, which can improve the work efficiency of subsequent exposure and development.

[0049] As shown in Figures 11 to 14As shown, the middle position of the transmission plate 611 is configured with a scraping assembly 7 for scraping the edge residual bubbles after pre-rolling, the scraping assembly 7 comprises a moving rod 701, the surface of the moving rod 701 is fixedly connected with a cylindrical cam 702, the surface of the cylindrical cam 702 is provided with an arc groove, the inside of the arc groove is slidably provided with a sliding column 704, one end of the sliding column 704 is fixedly connected with a fixed sleeve 703, the fixed sleeve 703 is fixedly connected with the transmission plate 611, and the lower end of the moving rod 701 is detachably connected with a scraper 707.

[0050] The present application fully considers that when the film and the plate are pre-rolled, in order to avoid that the middle of the film is left with some bubbles when the second extrusion roller 502 completely covers the film and rolls it, the second extrusion roller 502 is arranged to be slightly shorter than the width of the film, which can fully extrude the middle position of the film and avoid the bubbles remaining in the middle position of the film. However, after extruding the middle of the film, some bubbles will remain on the edges of the film on both sides of the second extrusion roller 502 and cannot be discharged. Even if the remaining position of the film is cut, when the film and the plate are formally rolled, the bubbles may not be completely extruded and discharged, and thus remain on the edge position of the plate and the film. Therefore, by arranging two groups of inclined scrapers 707 behind the second extrusion roller 502, after the second extrusion roller 502 fully extrudes and discharges the middle position of the film, the two groups of scrapers 707 can continue to scrape the bubbles on the edge position, which can improve the effect of discharging the bubbles between the film and the plate.

[0051] It should be noted that when a larger size film is rolled, the width of the film is larger, so after the second extrusion roller 502 rolls, more bubbles may remain on the edges. Therefore, when the transmission plate 611 adjusts the pressure value of the second extrusion roller 502 through the connecting rod 10 and the rotating sleeve 11, the downward movement of the transmission plate 611 drives the fixed sleeve 703 to move downward, the movement of the fixed sleeve 703 drives the sliding column 704 to move downward, and one end of the sliding column 704 slides in the arc groove on the surface of the cylindrical cam 702, so that the cylindrical cam 702 and the moving rod 701 rotate, the rotation of the moving rod 701 drives the scraper 707 to rotate, adjusts the position of the scraper 707 to tend to be "horizontal", and can scrape the bubbles on the edges of the larger size film, avoid a large number of bubbles remaining on the edge position of the film and the plate, and improve the scraping effect of the film.

[0052] Need to reiterate, by changing the second extrusion roller 502 roller pressure at the same time the angle of the scraper 707 adjustment, so that it can be on different width film pre-roller after the edge of the bubble processing, so as to improve the overall bubble processing effect between the film and the plate, and when the scraper 707 angle adjustment, the scraper 707 bottom surface and the surface of the film will tend to "parallel" state, so that the bubble scraping at the same time, can be positioned on the film, not only can facilitate the cutting piece 603 on the film remaining position cutting when the stability, but also will bubble to the edge of the film and the plate position after, at this time the residual bubble will be to a certain extent will be attached to the film on both sides of the plate, facilitate cutting piece 603 on the film cutting, at this time the cutting piece 603 cutting will not only assist the bubble discharge, but also effectively improve the film after the formal roller, bubble from the edge of the film cutting fast discharge, can effectively improve the film and the plate of the quality of the paste.

[0053] As shown in Figures 13 to 14 The surface of the moving rod 701 is fixedly connected with a rotating ring 705, the surface of the rotating ring 705 is rotatably connected with a limiting ring 706, the surface of the limiting ring 706 is rotatably connected with a first incomplete rack 708 through a pin shaft, the surface of the first incomplete rack 708 is meshingly connected with an incomplete gear 709, the incomplete gear 709 is meshingly connected with a second incomplete rack 711, the surface of the matching rod 606 below the transmission plate 611 is fixedly connected with a fixed ring 612, the surface of the fixed ring 612 is fixedly connected with a wedge block 610, the surface of the second incomplete rack 711 and the first incomplete rack 708 is slidingly connected with a working bin 710.

[0054] When the scraper 707 is adjusted in angle to remove bubbles from the edges of films of different widths, if the scraper 707 is directly rotated for adjustment, the film contacted by the lower end of the scraper 707 will be rubbed, causing wrinkles on the surface of the film, affecting the quality of the overall bonding of the film and the plate. Therefore, the rotating ring 705 and the limiting ring 706 are arranged on the surface of the moving rod 701, and when the matching rod 606 moves downward to adjust the second extrusion roller 502 and the scraper 707, the movement of the matching rod 606 drives the fixed ring 612 to move, and the movement of the fixed ring 612 drives the wedge block 610 to move. The movement of the wedge block 610 pushes the second incomplete gear rack 711 to slide in the working bin 710 through the inclined surface thereof. The sliding of the second incomplete gear rack 711 drives the incomplete gear 709 to rotate through meshing transmission. The rotation of the incomplete gear 709 drives the first incomplete gear rack 708 to rotate through meshing transmission. The rotation of the first incomplete gear rack 708 drives the limiting ring 706 to move upward through the hinged plate, and the movement of the limiting ring 706 drives the rotating ring 705 in the interior thereof to move. The rotating ring 705 drives the scraper 707 below to move upward a small distance through the moving rod 701, so that the scraper 707 loses contact with the film when rotating, avoiding damage to the film and affecting the overall bonding quality between the film and the plate.

[0055] It should be noted that after the scraper 707 is adjusted in angle by rotating and moving upward, the upward movement of the moving rod 701 drives the cylindrical cam 702 to move in opposition to the downward slide column 704, shortening the sliding time of the slide column 704 in the arc groove of the cylindrical cam 702 and improving the efficiency of the angle adjustment of the scraper 707 below. After the adjustment is completed, the continuous downward movement of the wedge block 610 gradually loses the extrusion force on the second incomplete gear rack 711, so that the first incomplete gear rack 708 no longer drives the scraper 707 to move upward through the hinged plate, and the scraper 707 is reset. When the matching rod 606 moves upward to reset, the scraper 707 also reversely rotates to lose contact with the film, thereby effectively improving the stability of the film during bonding and improving the overall bonding quality of the film and the plate.

[0056] It should be further noted that when the first incomplete gear rack 708 drives the scraper 707 to move upward and downward through the hinged plate, the scraper 707 rotates rapidly while moving upward under the cooperation of the transmission plate 611 and the cutting piece 603, improving the conversion speed when removing bubbles from films of different widths, effectively protecting the film and improving the bubble removal efficiency.

[0057] As Figures 4 to 6As shown, the bidirectional air cylinder 601 and the top plate 9 are fixedly connected, a spring is arranged between the matching rod 606 and the top plate 9, both ends of the top plate 9 are fixedly connected with cutting bins, and the cutting bins are fixedly arranged above the matching plate 8. The bidirectional air cylinder 601 drives the cutting piece 603 to adjust the position in the cutting bin through the adjusting rod 602.

[0058] When the adjusting rod 602 drives the matching rod 606 to move up and down through the inclined plate in the fixed cylinder 605, at this time, the spring arranged at the sliding position of the matching rod 606 and the top plate 9 is continuously pressed when the matching rod 606 moves downward, and at this time, the stability of the matching rod 606 after being pressed downward can be effectively improved through the rebounding force of the spring and the friction force between the inclined plate in the fixed cylinder 605 and the inclined groove in the matching rod 606, so that the stability after the pressure of the second extrusion roller 502 is adjusted is improved.

[0059] It should be noted that when the position of the cutting piece 603 is adjusted, the two groups of fixed cylinders 605 will move relatively, and because the inclination directions of the inclined plates inside are different, the fixed cylinders 605 can drive the matching rod 606 to move up and down through the inclined plate when moving relatively, so that the force transmitted by the transmission plate 611 to the connecting rod 10 and the rotating sleeve 11 is in a uniform state, and the force of the second extrusion roller 502 pre-rolling the film is fully changed in a gentle state, so that the position between the film and the plate is rolled, and the bubbles are fully discharged from the middle.

[0060] As shown in the figure, Figure 13 The upper end of the moving rod 701 is rotationally connected with the shell 1, the fixed sleeve 703 is sleeved outside the cylindrical cam 702, the fixed sleeve 703 drives the cylindrical cam 702 and the moving rod 701 to rotate through the slide column 704, and the scraper 707 is made of silica gel or rubber material.

[0061] When working, because the surface of the wedge block 610 in contact with the second incomplete rack 711 is arranged in a certain arc, when the wedge block 610 moves downward, the second incomplete rack 711 in the working bin 710 is first pushed to slide by the inclined surface, so that the moving rod 701 can be quickly driven to move upward, because one end of the slide column 704 slides in the arc groove on the surface of the cylindrical cam 702, at this time, before the cylindrical cam 702 rotates, the wedge block 610 has driven the moving rod 701 to move upward through the inclined surface, and when the slide column 704 slides in the sliding groove in the cylindrical cam 702 for a distance, the scraper 707 that has been “lifted” will rotate, so that the damage to the film caused by the rotation of the scraper 707 first can be effectively avoided, and the quality of the film and the plate being attached as a whole is affected;

[0062] It should be noted that since the second incomplete rack 711 and the first incomplete rack 708 are both sliding inside the working bin 710, when the wedge 610 loses the extrusion force on the second incomplete rack 711, the scraper 707 and the moving rod 701 will push the first incomplete rack 708 to slide reversely inside the working bin 710 under the action of gravity, and since the rotating ring 705 and the limiting ring 706 are rotationally connected, when the limiting ring 706 moves downward, it will first drive the hinged plate to move, and then the first incomplete rack 708 will slide reversely, which can avoid the scraper 707 from falling on the surface of the film instantaneously after losing the pushing force of the wedge 610 on the second incomplete rack 711, thereby preventing damage to the film and further improving the protection of the film.

[0063] As shown in Figures 6 to 9 The adjusting rod 602 and the cooperating sleeve 607 are rotationally connected with the output end of the driving motor 604, the adjusting rod 602 drives the cutting piece 603 to move inside the cutting bin, the cutting piece 603 drives the limiting strip 609 at one end of the arc rod 608 to slide inside the cooperating plate 8, and the cooperating plate 8 is provided with a cutting groove inside the position of the cutting piece 603.

[0064] During operation, since the adjusting rod 602 is slidingly connected with the cooperating plate 8 and one end is fixedly connected with one output end of the double-way air cylinder 601, when the double-way air cylinder 601 adjusts the position of the cutting piece 603, the inner side of the limiting strip 609 will be tightly attached to the side of the cut dry film after moving inside the cooperating plate 8, and since one end of the guide plate 613 and one end of the limiting strip 609 are both conically arranged, the cut film can be fully guided to be discharged through the discharge groove, and the cut film can be accurately guided by the limiting strip 609.

[0065] It should be noted that when the cutting piece 603 moves inside the cutting bin, since the cutting piece 603 is spline-connected with the output end of the driving motor 604, the driving motor 604 can stably cut the edge of the film even if the cutting piece 603 moves, and after cutting, the scraper 707 can be "driven" to release the bubbles at the edge, which can effectively avoid the bubbles remaining at the edge of the film and the plate, thereby improving the quality of the subsequent exposure of the PCB.

[0066] As shown in Figures 4 to 5 The adjusting rod 602 and the cooperating sleeve 607 are both sleeved on the surface of the output end of the driving motor 604, the driving motor 604 is fixedly connected with the cooperating plate 8, the adjusting rod 602 is slidingly connected with the cutting bin, and the cooperating plate 8 is provided with a stepped groove inside for placing the copper-clad plate and the dry film.

[0067] When working, the film and the plate are placed inside the matching plate 8, because the inside of the matching plate 8 is provided with the stepped groove for placing the copper-clad plate and the dry film, at this time, the plate is first inserted into the inside of the lower stepped groove, and then the film is inserted into the upper side of the matching plate 8, so that the film and the plate are tightly attached together, and the position accuracy of the two can be ensured during the pre-rolling and the formal rolling, the position deviation of the film during the rolling process can be avoided, and the effect of the film attached to the surface of the plate can be effectively improved.

[0068] As shown in Figure 9 and Figure 11 The matching rod 606 drives the wedge block 610 to move up and down through the fixing ring 612, the surface of the wedge block 610 is provided with a certain arc, the wedge block 610 is made of wear-resistant material, the inclined angle of the inclined plate inside the fixing cylinder 605 is consistent with the inclined angle of the inclined groove inside the matching rod 606, and the connecting plate 12 and the matching plate 8 are fixedly connected.

[0069] When working, the wedge block 610 and the second incomplete rack 711 are in contact, so that the second incomplete rack 711 can slide in the inside of the working bin 710, the up and down movement of the scraper 707 can be effectively adjusted, the effect of protecting the film can be improved, the surface of the film can be prevented from being damaged, and because the inclined angle of the inclined plate inside the fixing cylinder 605 is consistent with the inclined angle of the inclined groove inside the matching rod 606, when the fixing cylinder 605 drives the matching rod 606 to move up and down and needs to be stabilized, the inclined surface can be matched to prevent the matching rod 606 from being "lifted" and falling off, the stability of the second extrusion roller 502 after the pressure is applied can be effectively improved, so that the middle part of the film and the plate can be extruded, and the quality of the PCB plate exposure in the integrated circuit can be improved.
