Example one

Please refer to fig. 1 to 9, which are a first embodiment of the present utility model. The present embodiment discloses a circuit board manufacturing method and a perforation forming apparatus 100, and the circuit board manufacturing method is preferably realized by the perforation forming apparatus 100, but the present utility model is not limited thereto. The circuit board manufacturing method includes (or is sequentially performed) a preparation step S100, a first hole opening step S110, a pre-curing step S120, a second hole opening step S130, and a lamination curing step S140.

In order to facilitate understanding of the present embodiment, the respective contents of the preparation step S100, the first hole opening step S110, the pre-curing step S120, the second hole opening step S130, and the lamination curing step S140 will be described first, and the configuration of the perforation forming apparatus 100 will be described in due course, but the present utility model is not limited thereto. For example, in other embodiments not shown, any of the steps involved in the method for manufacturing a circuit board and the respective component structures of the perforation-forming apparatus 100 may be modified or omitted according to the requirements of the utility model (e.g., the lamination curing step may be omitted or replaced by other steps); or the circuit board manufacturing method may be implemented in a device different from the perforation forming apparatus 100.

The preparation step S100: as shown in fig. 1 and 2, the perforation forming apparatus 100 is provided, which in the present embodiment includes a table 1, a displacement mechanism 2 provided on the table 1, a hole digger 3 disposed opposite to the table 1, and a heater 4 to which the displacement mechanism 2 is mounted. Wherein the workbench 1 is used for placing objects to be perforated or heated, and the workbench 1 is used for arranging a prepreg PP in the embodiment, such as: an adhesive film (PP) is provided, but the present utility model is not limited thereto.

In this embodiment, the displacement mechanism 2 defines a first direction D1 and a second direction D2 perpendicular to each other according to the moving direction, and the first direction D1 and the second direction D2 can define a displacement plane together; that is, the displacement mechanism 2 can move along the first direction D1 and the second direction D2 perpendicular to each other, but the present utility model is not limited thereto. For example, in other embodiments of the utility model, not shown, the definition of the first direction D1 and the second direction D2 may also be independent of the direction of movement of the displacement mechanism 2.

Specifically, the displacement mechanism 2 of the present embodiment includes a horizontal displacement bracket 21 mounted on the table 1 and at least one slide cylinder 22 mounted on the horizontal displacement bracket 21. The horizontal displacement bracket 21 of the present embodiment can move on the table 1 along the first direction D1 and synchronously drive at least one sliding table cylinder 22, and the horizontal displacement bracket 21 can also control the movement of at least one sliding table cylinder 22 along the second direction D2. Thereby, the slide cylinder 22 can be moved to an arbitrary position on the table 1 in the first direction D1 and the second direction D2 by the horizontal displacement bracket 21.

The displacement mechanism 2 employs at least one of the slide table cylinders 22 in the present embodiment in two numbers; that is, the two slide cylinders 22 of the present embodiment are a first slide cylinder 22-1 mounted on the horizontal displacement bracket 21 and a second slide cylinder 22-2 mounted on the horizontal displacement bracket 21, respectively. In this embodiment, the hole digger 3 is mounted on the first slide cylinder 22-1, and the first slide cylinder 22-1 is movable on the table 1 along the displacement plane defined by the first direction D1 and the second direction D2 by the horizontal displacement bracket 21. Further, the first slide cylinder 22-1 is movable in a height direction H with respect to the table 1. The height direction H is perpendicular to the first direction D1 and the second direction D2.

Further, the heater 4 is mounted to the second slide cylinder 22-2, and the second slide cylinder 22-2 is located at the back of the first slide cylinder 22-1, but the present utility model is not limited thereto. The second slide cylinder 22-2 is movable on the table 1 along the displacement plane defined by the first direction D1 and the second direction D2 by the horizontal displacement bracket 21. In addition, the second slide cylinder 22-2 is also movable in the height direction H with respect to the table 1.

As shown in fig. 2, the displacement mechanism 2 of the present embodiment further includes a rotation mechanism 23 connecting the first slide cylinder 22-1 and the second slide cylinder 22-2. The rotation mechanism 23 can be used to rotate the first slide cylinder 22-1 and the second slide cylinder 22-2 to interchange the positions of the hole digger 3 and the heater 4.

For example, when there is an object on the table 1 to be perforated and heated, the horizontal displacement bracket 21 can position the first sliding cylinder 22-1 above the position where the object is to be perforated, and the first sliding cylinder 22-1 moves toward the object along the height direction H, so that the perforating device 3 can perform the perforation on the object. After that, the rotation mechanism 23 exchanges the second slide cylinder 22-2 with the first slide cylinder 22-1 by its horizontal rotation so that the second slide cylinder 22-2 is located above the position where the object is to be worked, and the second slide cylinder 22-2 is moved toward the object in the height direction H so that the heater 4 can directly perform the heating work on the object. Thus, the perforation forming apparatus 100 according to the present embodiment can perform two subsequent operations (e.g., the perforation operation and the heating operation) after one object is positioned by the rotating mechanism 23, so as to improve the operation efficiency.

Further, the rotation mechanism 23 of the present embodiment is not limited to the horizontal rotation manner in the first direction D1 or the second direction D2 to interchange the positions of the first slide cylinder 22-1 and the second slide cylinder 22-2. For example, in other embodiments of the utility model not shown, the rotation mechanism 23 can exchange the first slide cylinder 22-1 with the second slide cylinder 22-2 in a vertically flipped manner along the height direction H.

As shown in fig. 2, the hole cutter 3 is movable relative to the table 1 by the displacement mechanism 2. In detail, the hole digger 3 is movable in the first direction D1 and the second direction D2 with respect to the table 1 by the horizontal displacement bracket 21, and the hole digger 3 is movable in the height direction H with respect to the table 1 by the first slide cylinder 22-1, whereby the hole digger work can be performed on the object to be perforated on the table 1, but the present utility model is not limited thereto. For example, in other embodiments of the present utility model, not shown, the first sliding cylinder 22-1 with the hole digger 3 mounted thereon is mounted on a fixed frame, and a moving platform (for example, an XY-axis moving platform or an air bearing positioning moving platform) moves the object to be perforated directly to the position where the hole digger 3 orthographically projects onto the workbench 1 for the hole digger 3 to perform the hole digger operation.

Similarly, the heater 4 can be moved relative to the table 1 by the displacement mechanism 2. In detail, the heater 4 is movable in the first direction D1 and the second direction D2 with respect to the table 1 by the horizontal displacement bracket 21, and the heater 4 is movable in the height direction H with respect to the table 1 by the second slide cylinder 22-2, whereby the heating work can be performed on the object to be heated on the table 1.

As shown in fig. 2, the heater 4 of the present embodiment includes a temperature controller 41 mounted on the horizontal displacement bracket 21, a heating block 42 mounted on the slide cylinder 22, a heating rod 43 connected to the heating block 42 and electrically coupled to the temperature controller 41, and a temperature sensor 44 connected to the heating block 42 and electrically coupled to the temperature controller 41.

Wherein, the temperature controller 41 can maintain the heating block 42 at a predetermined temperature through the heating rod 43 and the temperature sensor 44. Specifically, the heating block 42 is configured to provide a heat source to heat a region on the object that it contacts. The heating rod 43 increases the temperature of the heating block 42 by the control of the temperature controller 41. The temperature sensor 44 senses the temperature of the heating block 42, and the temperature controller 41 can know the current temperature of the heating block 42 through the temperature parameter returned by the temperature sensor 44, so as to control the heating block 42 to maintain the preset temperature, so as to avoid overheating or incomplete heating of the area on the object contacted by the heating block 42.

The above is a description of the preparation step S100 (or the perforation forming apparatus 100) in the present embodiment, and the circuit board manufacturing method will implement the first perforating step S110, the pre-curing step S120, and the second perforating step S130 in cooperation with the perforation forming apparatus 100 in the following description; however, in other embodiments of the present utility model, not shown, the first hole forming step S110, the pre-curing step S120, and the second hole forming step S130 may be implemented by devices different from the hole forming apparatus 100, and the present utility model is not limited thereto.

The first hole opening step S110: as shown in fig. 1, 3 and 4, a pre-perforated PHO is cut on the prepreg PP. In the present embodiment, the prepreg PP is disposed on the table 1 of the perforation forming apparatus 100, and the hole digger 3 can form the pre-perforation PHO on the table 1 by the displacement mechanism 2. Wherein, the shape of the pre-perforated PHO is rectangular, but the utility model is not limited thereto. For example, in other embodiments of the utility model not shown, the shape of the pre-perforated PHO may be circular, oval, square, etc. according to the requirements of the utility model.

The pre-curing step S120: as shown in fig. 1, 5 and 6, curing is performed around the pre-perforated PHO of the prepreg PP, so that a portion of the prepreg PP within a predetermined distance PD from the hole edge of the pre-perforated PHO is cured to form a pre-cured portion PS; the pre-cured portion PS has an irregular inner edge IE, and an inner diameter of the irregular inner edge IE is smaller than an inner diameter of the pre-perforated PHO. In the present embodiment, the size of the heating block 42 of the heater 4 corresponds to the size of the pre-cured portion PS, and the pre-cured portion PS is formed by curing around the pre-perforated PHO of the prepreg PP by the heating block 42 by the displacement mechanism 2.

The prepreg PP is made of glass fiber cloth, resin, hardener, accelerator, solvent and filler. Furthermore, the resin of the prepreg PP comprises at least two epoxy groups. Because the prepreg PP is made of resin, the prepreg PP is gradually softened in the heating process and has fluidity, and then is gradually cured. But also because of this characteristic of the prepreg PP, the inner diameter of the pre-perforated PHO of the present embodiment is preferably greater than 0.5 millimeters (mm) for the portion of the prepreg PP to flow inward during curing to form the pre-cured portion PS. That is, the irregular-shaped inner edge IE is generated during the curing of the pre-cured portion PS of the prepreg PP by the heater 4.

It is noted that the preset distance is greater than 2mm when the content (RC) of the resin contained in the type used for the prepreg PP is greater than 60%; and when the content (RC) of the resin included in the type used for the prepreg PP is less than 60%, the preset distance is greater than 0.5 mm, but the present utility model is not limited thereto.

The second opening step S130: as shown in fig. 1, 7 and 8, a perforation HO is cut in the pre-cured portion PS to remove the irregular inner edge IE. In this embodiment, the hole digger 3 performs a hole digger operation again for the pre-perforated PHO of the prepreg PP (for example, the hole digger 3 cuts the pre-cured portion PS to form the perforation HO), and since the inner diameter of the irregular inner edge IE is smaller than the inner diameter of the pre-perforated PHO, the hole digger 3 can remove the irregular inner edge IE after the hole digger operation again to form the perforation HO. Wherein the center of the pre-perforated PHO, the center of the pre-cured portion PS, and the center of the perforated hole HO coincide with each other, and the inner diameter and hole pattern of the pre-perforated PHO are the same as those of the perforated hole HO, but the present utility model is not limited thereto.

The laminating and curing step S140: as shown in fig. 1 and 9, the prepreg PP is press-fit and cured between two substrates BD, so that the through holes HO are sealed by the two substrates BD to form a closed cavity SP. Therefore, the present utility model can perform the lamination curing step S140 to press-cure the prepreg PP between the two substrates BD after removing the irregular inner edge IE of the pre-cured portion PS through the pre-curing step S120 and the second opening step S130, so as to form a circuit board with the closed cavity SP, so as to avoid the side wall of the closed cavity SP from collapsing inwards in the lamination curing step S140.

It is noted that the outer diameter of the pre-cured portion PS is larger than the aperture of the through hole HO to ensure that the pre-cured portion PS is not entirely cut out by the hole digger 3, so that the pre-cured portion PS can avoid the side wall of the closed cavity SP from collapsing inward in the lamination curing step S140.

As described above, in the circuit board manufacturing method of the present embodiment, after the pre-curing portion PS surrounds the defined through hole HO, the lamination curing step S140 is performed to press-cure the prepreg PP between the two substrates BD, so as to form the closed cavity SP, so as to avoid the side wall of the closed cavity SP from collapsing inwards in the lamination curing step S140.

Example two

Please refer to fig. 10, which illustrates a second embodiment of the present utility model. Since this embodiment is similar to the first embodiment, the same parts of the two embodiments will not be described again, and the differences between the present embodiment and the first embodiment are described as follows:

In this embodiment, the number of the horizontal displacement brackets 21 of the displacement mechanism 2 is 2, that is, the two horizontal displacement brackets 21 of this embodiment are a first horizontal displacement bracket 21-1 mounted on the workbench 1 and a second horizontal displacement bracket 21-2 mounted on the workbench 1, the first horizontal displacement bracket 21-1 and the second horizontal displacement bracket 21-2 are respectively located at two sides of the workbench 1, wherein the first horizontal displacement bracket 21-1 is provided with the first sliding table cylinder 22-1, and the first sliding table cylinder 22-1 is provided with the hole digger 3 to control the hole digger 3 to conduct the hole digger operation; the second horizontal displacement bracket 21-2 is provided with the second sliding table cylinder 22-2, and the second sliding table cylinder 22-2 is provided with the heater 4 to control the heater 4 to perform heating operation.

In this way, the workbench 1 can move the prepreg PP into the working area of the first horizontal displacement bracket 21-1, and the first horizontal displacement bracket 21-1 cooperates with the first sliding table cylinder 22-1 to drive the hole digger 3 to conduct hole digger operation on the prepreg PP. After that, the workbench 1 moves the prepreg PP into the working area of the second horizontal displacement bracket 21-2, and the second horizontal displacement bracket 21-2 cooperates with the second sliding table cylinder 22-2 to drive the heater 4 to heat and pre-cure the prepreg PP. Thus, the present embodiment uses the first horizontal displacement bracket 21-1 and the second horizontal displacement bracket 21-2 to perform the punching operation and the heating pre-operation, respectively, to simplify the structural complexity of the perforation forming apparatus 100.
