Description

Technical Field

[0001] The utility model relates to the field of semiconductor manufacturing, and more specifically to a series pressure epoxy film curing fixture. Background Art

[0002] In the manufacturing process of surface acoustic wave filter CSP packaging devices, it is necessary to attach and wrap the epoxy film on the tube core (die) to protect and isolate the environment. Therefore, it is necessary to cover a layer of epoxy film on the ceramic substrate (for example, a substrate of 95mm*95mm size) with the tube core welded, and the total thickness of the coated substrate (hereinafter referred to as "film-coated substrate") is about 0.5mm.

[0003] In the lamination process, the epoxy film generally needs to undergo a curing process at 150°C for 3 hours in an oven.

[0004] In addition, a certain amount of pressure needs to be applied to the "laminated substrate" during the curing process to prevent thermal stress deformation caused by different thermal expansion coefficients of different materials.

[0005] The prior art uses two flat pressing plates to clamp the "laminated substrate" between them, and uses the gravity of the pressing plates or a spring clip to clamp it, and based on this, a jig is made. The jig according to the prior art is large in size and heavy in weight, and thus the space utilization rate of the oven is not high, and it is difficult to carry.

[0006] In addition, there are also jigs that stack the pressing plate and the "laminated substrate" at intervals and use gravity to flatten them. Although this jig solves the problems of weight and volume, the pressure on the upper and lower layers may gradually increase, making the pressure uneven and affecting the uniformity of the process.

[0037] According to an embodiment of the utility model, the rear side plate 2-2 is also configured to be provided with a through hole 2-7 thereon, so that the push rod cylinder of the first pressure plate is installed through the through hole 2-7.

[0038] Figure 3 and Figure 4 The schematic diagrams respectively show the front and back sides of the pressure plate of the serial pressure epoxy film curing jig according to the embodiment of the utility model.

[0039] refer to Figure 3 and Figure 4The front of the pressure plate is designed with a groove, and the "laminated substrate" is placed in the groove. The back of the pressure plate is convex. When multiple pressure plates are stacked together, the convex part on the back is pressed into the groove on the front of the next pressure plate to form a cavity, and the "laminated substrate" is inserted into the cavity.

[0043] Figure 5 Schematic diagram showing the first pressing plate of the serial pressing epoxy film curing fixture according to an embodiment of the utility model.

[0044] refer to Figure 5 The first pressure plate is configured to include: a push rod cylinder 5-1, an adjusting bolt 5-2, a pressure spring 5-3, a push rod 5-4, and a slide rail hole 5-5. The adjusting bolt 5-2 is connected to the push rod cylinder 5-1 by a thread, and the pressure on the pressure spring 5-3 is adjusted by adjusting the screwing distance relative to the push rod cylinder 5-1, thereby adjusting the pressure applied by the push rod 5-4 to the pressure plate to achieve the push operation.

[0045] According to an embodiment of the utility model, the first pressure plate is configured to be pushed by the pressure handle to press the pressure plate.

[0046] In addition, according to an embodiment of the utility model, by adjusting the bolt 5-2 to control the compression amount of the pressure spring 5-3, pressure control during extrusion is achieved to provide further control and adjustment of the pressure between the pressure handle and the pressure plate.

[0047] According to an embodiment of the utility model, the first pressure plate is configured to be designed with a slide rail hole 5 - 5 for being installed on the slide rail and sliding thereon.

[0048] FIG. 6( a ) and FIG. 6( b ) are schematic diagrams showing the pressure handle of the serial pressure epoxy film curing jig in the loading state and the pressing state respectively according to the embodiment of the present invention.

[0049] 6(a) and 6(b), the pressure handle 6-4 is configured in an L-shape and is configured to be connected to the frame through the pressure handle shaft hole 6-5.

[0050] According to an embodiment of the utility model, the pressure handle 6-4 is configured to have a working length R to meet the cavity distance a1 between multiple pressure plates 6-2 when in a loading state; and when in a clamping state, the cavity distance a2, that is, the thickness of the "laminated substrate 6-1".

[0051] By turning the pressure handle, the distance between the front end of the first pressure plate 6-3 and the rear side plate changes between c1-c2, and by adjusting the bolt, the length of the pressure spring changes between b1-b2 to provide further adjustment of the pressure of the first pressure plate.

[0052] According to an embodiment of the utility model, the pressure handle is also configured to have a self-locking function in a clamped state. When the pressure handle is in a clamped state, the pressure handle is constrained by the rear side plate of the frame, so that the clamping force generated by the pressure spring is equal to the supporting force of the rear side plate on the pressure handle, and the directions are opposite, thereby achieving self-locking.

[0053] Those skilled in the art should understand that, although according to an embodiment of the present invention, the pressure handle is configured in an L shape, and the rear side plate is configured with a pressure handle through hole so that the pressure handle contacts the first pressure plate through the through hole, the above example is only for demonstration and does not limit the scope of the present invention. Without departing from the scope of the present invention, it can also be configured in other shapes, for example, the pressure handle is configured in the shape of an eccentric wheel, and the first pressure plate is pressed by rotating around the pressure handle shaft hole provided on the surface of the rear side plate facing the first pressure plate.

[0054] Figure 7 It is a schematic diagram showing the hinge shaft and connecting rod of the pressure plate of the serial pressure epoxy film curing fixture according to an embodiment of the utility model.

[0055] refer to Figure 7 One end of the connecting rod 7-2 is connected to the connecting rod hole of the pressure plate through the hinge shaft 7-1 so that it can rotate around the hinge shaft 7-1; and the other end of the connecting rod 7-2 is configured to be constrained in the connecting rod long hole of the adjacent pressure plate through the hinge shaft so that it can slide up and down. According to an embodiment of the utility model, the hinge shaft 7-1 is configured as a three-step shaft to constrain the hinge shaft 7-1 to only slide or rotate in the groove of the connecting rod long hole, or rotate in the connecting rod hole.

[0056] According to the embodiment of the utility model, the connecting rod is configured so that multiple pressure plates can move in the direction of the slide rail at the same time and at equal distances. Since the pressure plate is constrained by the slide rail of the frame, the connecting rod, the hinge shaft, the connecting rod hole of the pressure plate and the connecting rod long hole, when loading, if any one of the pressure plates is pulled apart along the axis of the slide rail, all the stacked pressure plates will be separated at equal distances.

[0057] According to the serial pressure epoxy film curing jig of the utility model, by designing concave and convex pressure plates, the pressure plates are embedded in each other when stacked in series to form a cavity for loading, thereby saving the types of parts and the volume of the jig; by designing a slide rail on the frame, the movement of the pressure plate along the axial direction of the slide rail is constrained; by designing a pressure handle on the frame, when the pressure plate is pushed to perform a pressing work, it can self-lock in the pressing state; by designing a first pressure plate, the first pressure plate is between the pressure handle and the pressure plate, and is used to adjust and control the pressure of the pressing work; by designing a connecting rod constraint between the pressure plates, the movement distance between all the pressure plates is always equal.

[0058] Although the present disclosure has been described with exemplary embodiments, various changes and modifications may be suggested to one skilled in the art. The present disclosure is intended to encompass such changes and modifications as fall within the scope of the appended claims.

[0059] Any description in the utility model should not be understood as implying that any particular element, step or function is an essential element that must be included in the scope of the claims. The scope of the utility model subject matter is limited only by the claims.
