The multi-layer board is formed by stacking multiple layers alternately, some of the layers are printed with circuits with concave and convex shapes on the surface, and some of the other layers are resin films with insulating properties. For example, in order to manufacture a multilayer board with a multi-layer structure, the following steps must be repeated: a step of forming a circuit pattern on a substrate, a step of superimposing a resin film on the substrate, and a step of curing the resin film.

The cumulative stacking of multiple layers can be done by means of a laminating machine. Generally speaking, the lamination machine can perform lamination process, press the laminate and the substrate, so that the laminate and the substrate are initially attached to a laminate semi-finished product. Next, the plane pressing process is carried out, and the lamination machine flattens the laminated semi-finished product to make the surface flat.

At present, laminators may face the problem of poor lamination quality. One of the problems is that there will be air bubbles or air gaps remaining between the laminate and the substrate during pressure lamination, and the other problem is that the pressure distribution between the laminate and the substrate is uneven during pressure lamination.

In view of the above problems, the present invention discloses a laminating machine, which is helpful to solve the problem of poor quality of lamination in the existing laminating machine.

The laminating machine disclosed in the present invention comprises a laminating device, a flat pressing device and at least one air-filled sealing member. The lamination device includes two lamination parts, and the lamination device is arranged to sandwich a substrate and a laminate between the two lamination parts and press them, so that the laminate adheres to the surface of the substrate. The flat pressing device includes two flattening parts, and the flat pressing device is arranged to sandwich and press the close laminated material and the base material between the two flattening parts. The gas-filled sealing member is arranged between the two film pressing parts or between the two flattening parts. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. The first inflatable ring and the second inflatable ring are arranged to press against each other when the two film pressing members or the two flattening members are close to each other, so as to keep the space between the two film pressing members or the two flattening members in an airtight state .

Another disclosed lamination machine of the present invention includes two lamination parts, a conveying device and an air-filled sealing member. The conveying device is arranged to convey the object through the space between the two lamination members. The inflatable sealing member includes a first inflatable ring and a second inflatable ring disposed between the two film-pressing members. At least a portion of the delivery device is located between the first inflatable ring and the second inflatable ring. The first inflatable ring and the second inflatable ring are arranged to press against each other when the two film-pressing members are close to each other, so as to keep the space between the two film-pressing members in an airtight state.

Another disclosed film laminator of the present invention includes a flat pressing device, a conveying device and an air-filled sealing member. The flat pressing device includes two flattening pieces. The conveying device is arranged to convey the object through the space between the two flattening members. The gas-filled sealing member is arranged between the two film pressing parts or between the two flattening parts. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. At least a portion of the delivery device is located between the first inflatable ring and the second inflatable ring. The first inflatable ring and the second inflatable ring are arranged to press against each other when the two flattening members approach each other, so as to keep the space between the two flattening members in an airtight state.

Another disclosed lamination machine of the present invention comprises a lamination device, a plane pressing device and a sealing ring. The lamination apparatus is provided to closely adhere the base material and the laminate.

The inflatable sealing member 40 is disposed on the plane pressing device 20 , which can be used to keep the space between the two flattening members 210 in an airtight state. Specifically, the inflatable sealing member 40 includes a first inflatable ring 410 and a second inflatable ring 420 . The first inflatable ring 410 is disposed on the main body 211 of one of the flattening members 210 , and the second inflatable ring 420 is disposed on the main body 211 of the other flattening member 210 . At least a part of the conveying device 30 is located between the first inflatable ring 410 and the second inflatable ring 420 ; in detail, a part of each conveying film 310 is located between the first inflatable ring 410 and the second inflatable ring 420 .

In some other embodiments, a plurality of inflatable strips may be disposed on the body of the flattening member, and the inflatable strips may be connected to form an inflatable ring.

The lamination machine disclosed in the present invention can perform the following procedures: convey the laminate and the substrate to the lamination device through the conveying device; press the laminate and the substrate into the laminate semi-finished product (lamination process) through the lamination device; The conveying device transports the laminated semi-finished product from the lamination device to the flat pressing device; and the flat pressing device performs the flattening operation (plane pressing procedure) on the above-mentioned laminated semi-finished product, so that the laminated material of the laminated semi-finished product is flattened.

Referring to FIG. 4 , it is a schematic diagram of the lamination device of FIG. 2 adhering the laminate to the substrate. The conveying film 310 of the conveying apparatus 30 conveys the laminate P1 (eg, insulating resin film) and the base material P2 (eg, a substrate having a circuit or semiconductor element on the surface) between the two lamination members 110 of the laminating apparatus 10 . The lower lamination member 110 rises close to the upper lamination member 110 , so that the pressing unit 112 of the second lamination member 110 clamps the conveying film 310 , the laminate P1 and the substrate P2 . In this embodiment, the pressurizing unit 112 may be an air bag, which can be inflated and expanded to further press, so that the laminated material P1 is in close contact with the surface of the substrate P2. Here, the role of the transport film 310 is not only to transport and transport the laminate P1 and the base material P2, but also to prevent the laminate P1 from being heated and melted when the pressing unit 112 of the lamination tool 110 is provided with a heater. It is then attached to the lamination device 10.

When the lower lamination member 110 rises close to the upper lamination member 110 , the main bodies 111 of the two lamination members 110 can be closed to form a closed space S1 for accommodating the laminate P1 , the substrate P2 and the transport film 310 . Further, at this time, the closed space S1 can be decompressed by means of negative pressure suction, so as to eliminate the air bubbles in the laminate P1 and/or the air gap between the laminate P1 and the substrate P2, thereby improving the lamination process. Yield and adhesion quality.

The laminated material P1 and the base material P2 in close contact with each other become the laminated semi-finished product P12. Since the surface of the substrate P2 may be formed with concavities and convexities such as circuit patterns, through holes, or semiconductor elements, the laminate P1 will not be flat enough due to the influence of these concavities and convexities, and thus needs to be further flattened subsequently. Referring to FIGS. 5 and 6 , it is a schematic diagram of the flat press apparatus of FIG. 3 flattening the laminated material adhered to the base material. The conveying film 310 of the conveying device 30 conveys the laminated semi-finished product P12 between the two flattening members 210 of the flat pressing device 20 . The servo motor 221 of the driving mechanism 220 rotates, so that the main body 211 of the lower flattening piece 210 rises close to the main body 211 of the upper flattening piece 210, so that the flattening units 212 of the two flattening pieces 210 clamp the conveying film 310 and the laminated semi-finished product P12 . In this embodiment, the flattening unit 212 may include a flexible metal plate, which can push the laminate semi-finished product P12 to flatten the laminate P1 attached to the substrate P2. Therefore, by pressing the semi-finished product P12 by the two flattening units 212, the thickness of the finished product can be uniform, and the finished product has a flat mirror surface (surface of the laminate P1). Here, the role of the transport film 310 is not only to transport the laminated semi-finished product P12, but also to prevent the laminated material P1 from adhering to the flat surface after being heated and melted when the flattening unit 212 of the flattening member 210 is equipped with a heater. Pressurizing device 20 .

In addition, as shown in FIG. 6 , when the lower flattening member 210 rises close to the upper flattening member 210 , a closed space S2 can be formed between the two flattening members 210 to accommodate the laminated semi-finished product P12 and the conveying film 310 . In detail, the first inflatable ring 410 and the second inflatable ring 420 of the inflatable sealing member 40 may be in an uninflated initial state under normal conditions. When the main bodies 211 of the two flattening members 210 are close to each other, the first inflatable ring 410 and the second inflatable ring 420 are attached to the upper and lower transport membranes 310 respectively, and the first inflatable ring 410 and the second inflatable ring 420 are inflated to each other Pressing, so that the closed space S2 between the two flattening members 210 is kept in an airtight state. At this time, the closed space S2 can be decompressed by means of negative pressure suction, so as to eliminate the air bubbles and/or the flattening unit in the laminated semi-finished product P12 The air gap between 212 and the laminate semi-finished product P12, thereby improving the yield and flattening quality of the plane pressing process. The first inflatable ring 410 and the second inflatable ring 420 may be inflated and expanded simultaneously during the process of the two flattening members 210 approaching, or the two flattening members 210 may be inflated and inflated after the two flattening members 210 are approached.

Compared with some existing laminators that use a rigid follower including a spring or an elastic sheet as the sealing member, in this embodiment, the first inflatable ring 410 and the second inflatable ring 420 can be in an uninflated state before the closed space S2 is formed, Therefore, when the two flattening parts 210 are close to each other, they can have a larger stroke without being disturbed by the air-filled sealing member 40 , which helps the flattening parts 210 to push the thin laminated semi-finished product P12 . In addition, the feeding end and the discharging end of the flat pressing device 20 can have large openings to allow the conveying film 310 and the laminated semi-finished product P12 to pass through without interfering with the inflatable sealing member 40 , thereby contributing to the miniaturization of the flat pressing device 20 . change.

In addition, for some existing laminators that use a single inflatable ring (or sealing ring) as the sealing member, in the case of a transport film, although the side of the transport film close to the inflatable ring can be closely attached to the inflatable ring, but On the other side, it is difficult to fit closely with the rigid body of the flattening piece, which results in poor air tightness of the confined space. In this embodiment, since both the first inflatable ring 410 and the second inflatable ring 420 are flexible, they can closely fit the transport film 310 , which helps to increase the airtightness of the closed space S2 .

In this embodiment, the driving mechanism 220 may drive the flattening member 210 to push the pressing method. The servo motor 221 may move one of the flattening members 210 by a predetermined distance and then stop, so as to align the laminated material P1 and the substrate P2 ( The laminated semi-finished product P12) is pressed, wherein the predetermined distance may be included in the command input by the controller to the servo motor 221. Alternatively, the servo motor 221 may drive the lower flattening member 210 to push or stop pushing according to the pressure signal sensed by the load cell 230 . Further, when the load cell 230 senses that the pressure value is greater than or smaller than the preset threshold, the load cell 230 outputs a pressure signal to the servo motor 221 , thereby controlling the operation of the driving mechanism 220 .

In the first embodiment, the inflatable sealing member 40 is only disposed on the plane pressurizing device 20, but the present invention is not limited thereto. In some embodiments, another inflatable sealing member may be additionally provided in the lamination device, or only the lamination device has an inflatable sealing member. FIG. 7 is a schematic diagram of a laminating machine according to another embodiment of the present invention. In this embodiment, the laminating machine 1 a includes a laminating device 10 , a flat pressing device 20 , a conveying device 30 , an air-filled sealing member 40 and an air-filled sealing member 50 .

The inflatable sealing member 50 is provided in the lamination device 10 , which can be used to keep the space between the two lamination members 110 in an airtight state. Specifically, the inflatable sealing member 50 includes a first inflatable ring 510 and a second inflatable ring 520 . The first inflatable ring 510 is disposed on one of the lamination members 110 , and the second inflatable ring 520 is disposed in the other lamination member 110 . At least a portion of the delivery device 30 is located between the first inflatable ring 510 and the second inflatable ring 520 . When the lower lamination member 110 rises close to the upper lamination member 110 , the main bodies 111 of the two lamination members 110 can be closed to form a closed space S1 for accommodating the laminate P1 , the substrate P2 and the transport film 310 . In detail, before the second film-pressing member 110 approaches, the first inflatable ring 510 and the second inflatable ring 520 may be in an uninflated initial state. When the two film-pressing members 110 are close to each other, the first inflatable ring 510 and the second inflatable ring 520 are inflated and inflated to press against each other, so that the closed space S1 between the two film-pressing members 110 is kept airtight.

8 is a schematic diagram of a laminating machine according to yet another embodiment of the present invention. FIG. 9 is a partially enlarged schematic view of the laminating machine of FIG. 8 . The laminator includes a flat pressing device 20, a conveying device 30 and a sealing ring 40b. For convenience of description and easy understanding of the differences between this embodiment and other embodiments, FIG. 8 omits to show some objects of the lamination machine (eg, lamination device, driving mechanism, etc.).

The flat pressing device 20 includes two flattening members 210 arranged in opposite directions, and each flattening member 210 includes a main body 211 and a flattening unit 212 which are connected to each other. The main body 211 can be vertically lifted and lowered by the driving device, so that the flattening units 212 of the two flattening members 210 are close to each other, so as to flatten the laminate on the surface of the substrate.

The conveying device 30 is provided to convey the objects (substrates and/or laminates) through the flat pressing device 20 . The conveying device 30 includes two conveying films 310, which are, for example, but not limited to, polyethylene terephthalate (PET) films, and the conveying films 310 form a continuous tape-like film. A plurality of rollers (not shown) of the conveying device 30 can be used to take up the conveying film 310, and the object (substrate and/or laminate) can be sandwiched between the two conveying films 310, so that the two The film 310 is transported to connect the object to move relative to the flat pressing device 20 .

The sealing ring 40b is, for example, but not limited to, an O-ring, which is provided on the main body 211 of one of the flattening members 210 of the flat pressing device 20 . Specifically, the main body 211 has an annular groove 211b and an air passage 211c communicating with the groove 211b, and the sealing ring 40b is movably disposed in the groove 211b. The air passage 211c can be connected to a gas supply source (not shown), so that gas (eg, air, nitrogen or helium) can be introduced into the groove 211b through the air passage 211c, so that the sealing ring 40b can be in a Active between a sealed state (as shown in Figure 9) and an initial state (as shown in Figure 8).

In this embodiment, the annular groove 211b is close to the edge of the flattening unit 212 of the flat pressing device 20, and the groove 211b has an opening 2122. The opening 2122 is located on the outer surface of the main body 211, and the width W1 of the opening 2122 is smaller than the maximum width W2 of the sealing ring 40b. The groove 211b further has a bottom wall 2123 opposite to the opening 2122 , and the width W1 of the opening 2122 is smaller than the width W3 of the bottom wall 2123 .

As shown in FIGS. 8 and 9 , when the plane pressing device 20 is not in operation, the sealing ring 40b is normally in the initial state. In the initial state, the sealing ring 40b is separated from the edge of the opening 2122 .

10 and 11 together, wherein FIG. 10 is a schematic view of the sealing ring of the laminator of FIG. 8 in a sealed state, and FIG. 11 is a partially enlarged schematic view of the laminator of FIG. 10 . The conveying device 30 conveys the laminated semi-finished product P12 between the two flattening members 210 of the flat pressing device 20 . The main body 211 of the lower flattening member 210 is driven to rise close to the main body 211 of the upper flattening member 210 , so that the flattening units 212 of the two flattening members 210 clamp the conveying film 310 and the laminated semi-finished product P12 . While or after the flattening unit 212 clamps the conveying film 310 and the laminated semi-finished product P12, gas is introduced into the groove 211b from the air passage 211c, so that the sealing ring 40b is changed from the initial state to the sealing state. Further, the sealing ring 40b can be a rigid material or a material with low elastic strain, which can be pushed by the gas to move upward when the gas is filled into the groove 211b, so as to close the opening 2122 of the groove 211b. Part of the sealing ring 40b protrudes from the opening 2122 to be attached to the conveying device 30 and press against the main body 211 of the other flattening member 210 . In this way, the closed space S2 between the two flattening members 210 can be kept in an airtight state. At this time, the closed space S2 can be decompressed by means of negative pressure extraction, so as to eliminate the air bubbles in the laminated semi-finished product P12 and/or flatten it. The air gap between the unit 212 and the laminate semi-finished product P12 further improves the yield and the flattening quality of the plane pressing process.

8 to 11 illustrate that the sealing ring 40b is disposed in the groove 211b formed in the plane pressing device 20 as an example, but the present invention is not limited thereto. In other embodiments, the sealing ring may be changed to be provided on the lamination member of the lamination device, or the sealing ring may be additionally provided in the lamination device in addition to the plane pressing device.

To sum up, the laminator according to the present invention is provided with an inflatable sealing member, wherein the inflatable sealing member includes a first inflatable ring and a second inflatable ring. When the two film-pressing parts or the two flattening parts are close to each other, the first inflatable ring and the second inflatable ring are attached to each other, so that the space between the two film-pressing parts or the two flattening parts can be kept in an airtight state. Taking the inflatable sealing member disposed between the two flattening members as an example to further illustrate, since the first inflatable ring and the second inflatable ring can be in an uninflated state before forming a closed space, the two flattening members can not be affected when they are close to each other. The inflatable sealing member interferes and has a large stroke, which helps the flattening member to push the thin laminated semi-finished product. In addition, the feeding end and the discharging end of the flat pressing device can have large openings to allow the conveying film and the laminated semi-finished product to pass through without interfering with the inflatable sealing member, thereby contributing to the miniaturization of the flat pressing device. In addition, both the first inflatable ring and the second inflatable ring have flexibility and can closely fit the conveying film, which helps to increase the airtightness of the closed space.

Furthermore, the laminator disclosed in the present invention can also be equipped with a sealing ring, which is arranged in the groove, and the groove can be filled with gas to push the sealing ring to protrude from the groove. A part of the sealing ring protruding from the groove can keep the closed space between the two lamination parts of the lamination device and/or between the two flat parts of the plane pressing device in an airtight state. At this time, the closed space can be decompressed by means of negative pressure suction, thereby improving the yield rate and lamination quality of the lamination machine.
