Below, with reference to the attached drawings, embodiments of the present application will be described in detail so that those skilled in the art can easily implement them. However, the present application may be implemented in various different forms and is not limited to the embodiments described herein. In order to clearly explain the present application in the drawings, parts that are not related to the description are omitted, and similar reference numerals are assigned to similar parts throughout the specification.

Throughout this specification, when a part is said to be “connected” to another part, this means not only “directly connected” but also “electrically connected” or “indirectly connected” with another element in between. "Includes cases where it is.

Throughout this specification, when a member is said to be located “on”, “above”, “at the top”, “below”, “at the bottom”, or “at the bottom” of another member, this means that a member is located on another member. This includes not only cases where they are in contact, but also cases where another member exists between two members.

Throughout the specification of the present application, when a part "includes" a certain component, this means that it may further include other components rather than excluding other components unless specifically stated to the contrary.

For reference, terms related to direction or position (top, upward, downward, side, longitudinal direction, width direction, etc.) in the description of the embodiments of the present application are explained based on the arrangement state of each component shown in the drawings. For example, when viewed in Figure 1, the vertical direction may be the normal direction of the drawing, and the longitudinal direction may be from 3 o'clock to 9 o'clock. Additionally, when viewed in FIGS. 2 and 3, the vertical direction may be from 12 o'clock to 6 o'clock, and the longitudinal direction may be from 3 o'clock to 9 o'clock. Additionally, when viewed in FIG. 4, the vertical direction may be from 12 o'clock to 6 o'clock, and the longitudinal direction may be from 4 o'clock to 10 o'clock.

However, this direction setting may vary depending on the arrangement of the original device. For example, if necessary, the present device may be arranged so that the upward direction based on FIG. 1 is directed in a horizontal direction (left and right direction), and as another example, the present device may be arranged so that the upward direction based on FIG. 1 is directed in an oblique direction. .

The present application relates to a member applied to a package sawing kit and a package sawing kit including the same.

1 is a schematic configuration diagram of a package sawing kit according to an embodiment of the present application.

Referring to Figure 1, the package sawing kit 10 according to an embodiment of the present application is a member 100 (hereinafter referred to as 'member 100') applied to the package sawing kit according to an embodiment of the present application. .) and a body portion 200.

A plurality of packages (P) individually cut from the input strips may be placed on the member 100 disclosed herein. For example, each package P cut from a strip by a cutting module (not shown) is transported by a picker module (not shown) and placed (placed) on the receiving space 111 formed in the member 100. It can be.

In this regard, the member 100 includes a seating portion 110 that forms a receiving space recessed in the downward direction so that the package P is seated, and a coupling portion 120 extending from the lower surface of the seating portion 110. It can be manufactured to do so.

Figure 2 is an enlarged view of the support portion of the package sawing kit according to an embodiment of the present application.

Referring to Figure 2, the coupling portion 120 may be provided with a support portion 121 inserted to penetrate the hole 201 formed in the body portion 200 of the package sawing kit 10.

In this regard, as sawing and singulation technology for semiconductor packages advances, the size of individual packages (P) is gradually becoming smaller, and accordingly, each accommodation space for placing cut individual small packages (small packages) The size must be able to be miniaturized accordingly, and techniques such as laser processing and molding processing can be applied to produce this miniaturized package sawing kit 10. In particular, using a mold already manufactured in a predetermined shape In the case of the molding processing method, when processing the member 100 that forms the receiving space where the package P is seated, the target composition such as rubber is injected into the mold in a high-temperature liquid state and then cooled. Through this, the member 100 is manufactured in a shape having an accommodation space. At this time, in the process of cooling the target composition, the target composition such as rubber shrinks, so that the desired shape of the member 100 at the time of design and the actual production are changed. Errors may occur between the shapes of the formed member 100.

In particular, due to differences in characteristics (contraction force, degree of contraction, etc.) between the body portion 200 made of materials such as aluminum and steel and the member 100 made of materials such as rubber, it is necessary to place a small package. There was a problem that it was difficult to precisely manufacture the specifications of the package sawing kit (10).

In consideration of this, when manufacturing the package sawing kit 10 disclosed herein, a hole is formed through or recessed in the vertical direction in the body portion 200 of the package sawing kit 10 made of metal. At least one (201) is provided, and the object composition forming the member 100 is introduced into the hole 201, and molding processing is performed on the object composition, so that the object is introduced into the hole 201. After the composition is cooled, the support portion 121 is formed, and the shrinkage deformation of the member 100 in the direction perpendicular to the vertical direction is reduced by the support portion 121 to form a space between the body portion 200 and the member 100. This is to reduce the standard deviation due to the difference in shrinkage force.

Additionally, referring to FIG. 2 , a plurality of support portions 121 may be arranged at intervals from each other in the edge area (outer portion) of the seating portion 110 . For example, referring to the enlarged view A of FIG. 2, at one end (9 o'clock direction in FIG. 2) in the longitudinal direction of the member 100, a first support portion 121a, a second support portion 121b, and a third support portion ( Each of 121c) and the fourth support portion 121d may be formed at a longitudinal distance from each other.

Meanwhile, according to an embodiment of the present application, the distance between the plurality of support parts 121 is the distance between a pair of support parts disposed on the longitudinal outer portion (9 o'clock direction in FIG. 2) of the body part 200. The gap between the pair of support parts disposed on the longitudinal inner side of the body 200 (3 o'clock direction in FIG. 2) may be set to be narrow compared to the gap between the pair of support parts. For example, the gap between the first support part 121a and the second support part 121b in FIG. 2 is narrower than the gap between the second support part 121b and the third support part 121c between the holes 201. The gap can be set, and similarly, the hole 201 is formed so that the gap between the second support part 121b and the third support part 121c is narrower than the gap between the third support part 121c and the fourth support part 121d. The interval between them can be set.

In this regard, the standard (length) of the member 100 in the longitudinal direction (from 3 o'clock to 9 o'clock in Figure 2) is manufactured to be relatively large compared to the standard (width) in the width direction (normal direction of the drawing in Figure 2). In this case, the degree to which the outer region in the longitudinal direction of the member 100 is contracted by molding processing may be greater than the degree to which the inner region (center region) in the longitudinal direction is contracted by molding processing, and taking this into account, the member ( The gap between the support portions 121 formed to correspond to the longitudinal outer portion (e.g., the 3 o'clock direction end or the 9 o'clock direction end in FIG. 2) of the longitudinal inner portion (e.g., the longitudinal inner portion (e.g., of the member 100) By setting the spacing between the support portions 121 formed to correspond to the longitudinal center (e.g., center, etc.) narrowly (tightly), the member 100 can achieve an overall uniform shrinkage prevention effect based on the longitudinal direction.

In other words, the gap between the support parts 121 or the gap between the holes 201 for forming the support parts 121 becomes relatively wider toward the inner part (center part) based on the longitudinal or width direction of the package sawing kit 10. It can be set to

Figure 3 is an enlarged view of the seating portion of the package sawing kit according to an embodiment of the present application.

Referring to FIG. 3, the seating portion 110 formed on the upper surface of the member 100 to load the packages (P) partitions the receiving space 111 so that each of the plurality of packages (P) is seated at mutual intervals. A side guide 112 may be provided.

Additionally, referring to the enlarged view B of FIG. 3, the side guide 112 may be provided in a tapered shape with a cross-sectional area that increases downward.

For reference, the side guide 112 may be referred to differently as a wall guide, side guide, etc., and the side guide 112 may be used as an adjacent package when a plurality of packages (P) are seated in the package sawing kit 10. A top image of the package sawing kit (10) is photographed with a predetermined gap between the (P), and when a vision inspection (Vision Dimension) is performed using the captured top image, the individual packages (P) are strictly inspected. By allowing them to be clearly distinguished and identified, inspection defects can be compensated for.

On the other hand, managing to prevent package overlap identification errors (overkill) from occurring during inspection by ensuring that a certain gap is formed between adjacent packages (P) is more important in the case of small packages where the size of the package (P) is relatively very small. It can work well.

Figure 4 is a schematic configuration diagram of an adsorption module including a package sawing kit according to an embodiment of the present application.

Referring to FIG. 4, the adsorption module 1 is a conversion kit in which a plurality of vacuum holes 1111 are formed in the vertical direction and may be equipped with a package sawing kit 10. The package (P) placed on the adsorption module (1) may be placed on the package sawing kit (10).

For example, the adsorption module 1 may include a negative pressure transmission plate structure 1112. The negative pressure transmission plate structure 1112 can adsorb the package sawing kit 10 and communicate with a negative pressure generator (not shown) and a plurality of vacuum holes 1111 of the package sawing kit 10.

In addition, the package sawing kit 10 may be placed on the upper surface of the negative pressure transmission plate structure 1112, and the negative pressure transmission plate structure 1112 may communicate with the negative pressure generator (not shown) and the vacuum hole 1111. . In addition, the negative pressure transmission plate structure 1112 may include a product adsorption connection part and a kit adsorption part in which negative pressure is formed or the negative pressure formation is released so that the product and package sawing kit 10 is adsorbed.

For example, the negative pressure transmission plate structure 1112 is formed in a portion of the package sawing kit 10 opposite to the portion where the plurality of vacuum holes 1111 are formed and adsorbs the product to communicate with the negative pressure former and the vacuum hole 1111. It may include a connection part (not shown).

In this regard, the product adsorption connection portion (not shown) may transmit negative pressure action and negative pressure release by the negative pressure generator to the vacuum hole 1111. Specifically, the negative pressure transmission plate structure 1112 may include a communication port that communicates the product adsorption connection (not shown) and the negative pressure generator, and when the negative pressure generator inhales gas (generates negative pressure), the product adsorption connection (not shown) The gas in the vacuum hole 1111 flows into the negative pressure generator, and accordingly, the gas in the vacuum hole 1111 flows into the negative pressure generator through the product adsorption connection (not shown), and accordingly, negative pressure is formed in the vacuum hole 1111. The package (P) placed on the package sawing kit (10) may be adsorbed. In addition, when the negative pressure generator releases (stops) the negative pressure generation, the negative pressure generation in the vacuum hole 1111 communicating with the negative pressure generator through the negative pressure transmission plate structure 1112 will stop, and the adsorption of the vacuum hole 1111 will stop. You can.

In addition, referring to the enlarged view A of FIG. 4, the adsorption module 1 physically holds the package sawing kit 10, and is attached to the protrusion 114 of the neighboring adsorption module when approaching the neighboring adsorption module in the vertical direction. By including a clamp 113 that is released by gripping, the coupling force between the negative pressure transmission plate structure 1112 and the package sawing kit 10 is improved and the arrangement of the package sawing kit 10 with respect to the negative pressure transmission plate structure 1112 Alternatively, when removing, the package sawing kit 10 can be removed by releasing the grip of the package sawing kit 10. Accordingly, even if vacuum adsorption is stopped due to an unexpected problem, the package sawing kit 10 can be prevented from being unexpectedly removed from the negative pressure transmission plate structure 1112.

Below, we will briefly look at the operation flow of the present application based on the details described above.

For example, in step S11, the body portion 200 may be prepared by drilling a hole 201 at a predetermined position in the plate-shaped body portion 200 made of a metal material.

As another example, in step S11, the body portion 200 may be prepared through molding using a mold manufactured to form a hole 201 through a predetermined position.

Next, in step S12 (b) a receiving space 111 is formed that is depressed in the downward direction so that the package P is seated, and a member 100 including a support portion 121 inserted to penetrate the hole 201 You can prepare.

Specifically, in step S12, molding processing of the target composition may be performed while the target composition is introduced into the hole 201. For example, the target composition may include rubber.
