It should be noted that these drawings are intended to illustrate the general characteristics of structure and/or methods utilized in certain example embodiments and to supplement the written description provided below. These drawings are not, however, to scale and may not precisely reflect the precise structural or performance characteristics of any given embodiment, and should not be interpreted as defining or limiting the range of values or properties encompassed by example embodiments. For example, the relative thicknesses and positioning of molecules, layers, regions and/or structural elements may be reduced or exaggerated for clarity. The use of similar or identical reference numbers in the various drawings is intended to indicate the presence of a similar or identical element or feature.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those of ordinary skill in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements, and thus their description will be omitted.
It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. Like numbers indicate like elements throughout. As used herein the term “and/or” includes any and all combinations of one or more of the associated listed items. Other words used to describe the relationship between elements or layers should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” “on” versus “directly on”).
It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of example embodiments.
Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises”, “comprising”, “includes” and/or “including,” if used herein, specify the presence of stated features, integers, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.
Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an implanted region illustrated as a rectangle may have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of example embodiments.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, such as those defined in commonly-used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
FIG. 1 is a schematic view illustrating an apparatus of packing a semiconductor package according to an example embodiment of the inventive concepts, and FIG. 2 is a schematic view illustrating a method of receiving a semiconductor package in a pocket of a carrier tape of FIG. 1.
Referring to FIGS. 1 and 2, an apparatus 1 of packing a semiconductor package according to the example embodiments may include a carrier tape supply unit 10, a semiconductor package packing unit 20, and a carrier tape winding unit 30.
The carrier tape supply unit 10 supplies a carrier tape T1 to the semiconductor package packing unit 20. The semiconductor package packing unit 20 packs a semiconductor package in the carrier tape T1. The carrier tape winding unit 30 winds the carrier tape T1 in which the semiconductor package is packed.
The carrier tape supply unit 10 includes a carrier tape supply reel 12 and a reel driving part (not shown). The carrier tape T1 is wound round the carrier tape supply reel 12. The carrier tape T1 may be formed of a resin material containing a conductive material. The reel driving part (not shown) rotates the carrier tape supply reel 12. When the carrier tape supply reel 12 is rotated clockwise by the reel driving part, the carrier tape T1 may be unwound from the carrier tape supply reel 12.
The carrier tape T1 may have a plurality of pockets P receiving a plurality of the semiconductor packages PKG. The plurality of pockets P may be formed along a longitudinal direction of the carrier tape T1 by equal intervals. Transfer holes H, which are used for transferring the carrier tape T1, may be formed at both edge regions of the pockets P to be arranged in lines. Protrusions 231 of a sprocket 230 described later are inserted in the transfer holes H. The sprocket 230 and the protrusions 231 are illustrated in FIG. 4. Due to a rotation of the sprocket 230, the protrusions 231 are inserted in the transfer holes H and then the protrusion 231 push sidewalls of the transfer holes H to get out from the transfer holes H. According to these operations, the carrier tape T1 is moved straight toward the semiconductor package packing unit 20. The movement of the carrier tape T1 may also be guided by a transfer rail 21.
The semiconductor package packing unit 20 includes a picker 22, a cover tape supply reel 24, an upper heating roller 26 a, and a lower heating roller 26 b. The picker 22 picks up the semiconductor package PKG and then puts the semiconductor package PKG in the pocket P of the carrier tape T1. The picker 22 may pick up the semiconductor package PKG by a vacuum suction method. The cover tape supply reel 24 may disposed over the carrier tape T1. A cover tape T2 is wound round the cover tape supply reel 24. The cover tape T2 may be formed of a resin material containing a conductive material. When the cover tape supply reel 24 is rotated counterclockwise by a reel driving part (not shown), the cover tape T2 may be unwound from the cover tape supply reel 24.
The upper heating roller 26 a is disposed on the carrier tape T1 and the lower heating roller 26 b is disposed under the carrier tape T1 to face the upper heating roller 26 a. The carrier tape T1 and the cover tape T2 are disposed between the upper heating roller 26 a and the lower heating roller 26 b. The upper and lower heating rollers 26 a and 26 b bond the cover tape T2 on the carrier tape T1 in thermo-compression. A groove (not shown) may be formed in the lower heating roller 26 b so that the pocket P of the carrier tape T1 may not be in contact with the lower heating roller 26 b. Heat blocks may be replaced with the upper and lower heating roller 26 a and 26 b. The heat blocks may move in up and down directions to bond the cover tape T2 to the carrier tape T1 using thermocompression.
The carrier tape winding unit 30 includes a carrier tape adhesion member 100, a carrier tape transfer member 200, a carrier tape cut member 300, and a reel replacement member 400.
FIG. 3 is an enlarged view of the carrier tape winding unit of FIG. 1, and FIG. 4 is a cross-sectional view taken along a line A-A′ of FIG. 3. Referring to FIGS. 3 and 4, the carrier tape adhesion member 100 include feeder 110, a chuck 120, a tape adhesion tool 130, an adhesive tape cutter 140, and an adhesive tape pressurization tool 150.
The feeder 110 may be disposed over and on the right of a winding reel 420. A adhesive tape T3 is wound round the feeder 110. When the feeder 110 is rotated counterclockwise by a driving part (not shown), the adhesive tape T3 may be unwound from the feeder 110.
The chuck 120 may be disposed over and on the left of the winding reel 420 a to face the feeder 110. The chuck 120 may move straight toward the feeder 110 to chuck the front of the fixing tape T3 unwound from the feeder 110. For example, the chuck 120 may move straight in a direction far away from the feeder 110 to extend the chucked fixing tape T3 in length.
The tape adhesion tool 130 includes a first adhesion tool 132 and a second adhesion tool 134. The first adhesion unit 132 and the second adhesion unit 134 are disposed between the feeder 110 and the chuck 120 and are spaced apart from each other by a desired (or, alternatively a predetermined) interval in a horizontal direction. The first adhesion unit 132 picks up one end of a portion having a desired (or, alternatively a predetermined) length of the fixing tape T3 and the second adhesion unit 134 picks up another end of the portion having the desired (or, alternatively a predetermined) length of the fixing tape T3. The first and second adhesion units 132 and 134 may pick up the fixing taper T3 by a vacuum suction method. The portion having the desired (or, alternatively a predetermined) length of the fixing tape T3 may be cut from the fixing tape T3 by the adhesive tape cutter 140 in the state that the first and second adhesion units 132 and 134 pick up the portion having the desired (or, alternatively a predetermined) length of the adhesive tape T3.
The first and second adhesion units 132 and 134 may move in up and down directions. In the state that the first and second adhesion units 132 and 134 pick up the cut adhesive tape T3 (i.e., the cut portion having the desired (or, alternatively a predetermined) length of the adhesive tape T3), the first and second adhesion units 132 and 134 descend to bond the cut adhesive tape T3 to the winding reel 420 a. In more detail, the first and second adhesion units 132 and 134 may bond the front end of the carrier tape T1 to the winding reel 420 a before a wind of the winding reel 420 a is started. The first and second adhesion units 132 and 134 may attach a cut back end of the carrier tape T1 to the winding reel 420 a or the outermost wound portion of the carrier tape T1 after the winding of the winding reel 420 a is completed. This will be described in more detail later.
The tape pressurization tool 150 may be disposed between the first adhesion unit 132 and the second adhesion unit 134. The tape pressurization tool 150 may include a body 152 and a pressurization part 154. The pressurization part 154 is a combination of a bottom surface of the body 152 and a pressurization curved surface 155 having an upward concave shape 155 formed on a bottom surface of the pressurization part 154. The tape pressurization tool 150 may move in up and down directions. The tape pressurization tool 150 descends toward the winding reel 420 a so that the pressurization curved surface 155 pressurizes the adhesive tape T3. An adhesion force of the adhesive tape T3 may be improved by the pressurization force of the tape pressurization tool 150.
The carrier tape transfer member 200 transfers the carrier tape T1 to the winding reel 420 a. The carrier tape transfer member 200 includes a transfer rail 220, the sprocket 230, and a guide 240.
As illustrated in FIG. 4, the transfer rail 220 includes a rail part 222 and grippers 224. The rail part 222 extends in a first direction which is the transfer direction of the carrier tape T1 toward the winding reel 420 a. The rail part 222 guides the carrier tape T1 to be transferred toward the winding reel 420 a. A pair of guide sills 223 are formed on a top surface of the rail part 222. Both edge portions of the carrier tape T1 are safely mounted on the pair of guide sills 223, respectively. The guide grippers 224 are disposed over the guide sills 223 to prevent the carrier tape T1 from breaking away from the transfer rail 220.
The sprocket 230 is disposed over the rail part 222 to transfer the carrier tape T1. The sprocket 230 may penetrate the guide gripper 224 and be disposed over the guide sill 223. A plurality of protrusions 231 are formed on a circumferential surface of the sprocket 230. The plurality of protrusions 231 are inserted in the transfer holes H of the carrier tape T1 by the rotation of the sprocket 230 and then the protrusions 231 push sidewalls of the transfer holes H to get out from the transfer holes H. According to these operations, the carrier tape T1 moves straight toward the winding reel 420 a. The sprocket 230 may be intermittently rotated by a driving part 232 for a step movement of the carrier tape T1. For example, the driving part 232 may be a step motor.
The guide 240 is disposed under the transfer rail 220. The guide 240 may go ahead and back in a longitudinal direction of the transfer rail 220. The guide 240 goes ahead to a space between an end portion of the transfer rail 220 and the winding reel 420 a and supports the carrier tape T1 passing through the end portion of the transfer rail 220.
The carrier tape cut member 300 cuts the carrier tape T1 after the wind of the carrier tape T1 on the winding reel 420 a is completed. The carrier tape cut member 300 includes a carrier tape holder 320 and a carrier tape cutter 340. The carrier tape holder 320 pressurizes and holds the carrier tape T1 to prevent the carrier tape T1 wound on the winding reel 420 a from being unwound. For example, the carrier tape holder 320 may pressurize the carrier tape T1 wound in a first quadrant with respect to a center of the winding reel 420 a. The carrier tape cutter 340 may be disposed between the transfer rail 220 and the winding reel 420 a. The carrier tape cutter 340 cuts the carrier tape T1 held by the carrier tape holder 320. For example, the carrier tape cutter 340 may cut the carrier tape T1 at any location between the end portion of the transfer rail 220 and the top of a circumferential surface of the winding reel 420 a.
FIG. 5 is a plan view illustrating the reel replacement member of FIG. 3 and FIG. 6 is a schematic view illustrating an operation replacing a winding reel by a reel replacement member.
Referring to FIGS. 3, 5, and 6, the reel replacement member 400 replaces the winding reel 420 a where winding of the carrier tape T1 is completed with a new winding reel 420 b. Additionally, after winding of the winding reel 420 b is completed, the reel replacement member 400 may replace the winding reel 420 b with another new winding reel 420 c again. The reel replacement member 400 includes a rotation axis 410, an axis support member 430, an axis driving part 440, and a base driving part 450.
The rotation axis 410 is separated from the end portion of the transfer rail 220 in the transfer direction (hereinafter, referred to as ‘a first direction’) of the carrier tape T1. An axis of the rotation axis 410 is aligned in a second direction perpendicular to the first direction in a plan view, as illustrated in FIG. 5. The rotation axis 410 may be provided with a plurality of the winding reels 420 a, 420 b, and 420 c. The plurality of the winding reels 420 a, 420 b, and 420 c are rotated clockwise to be wound with the carrier tape in which the semiconductor packages are packed. Movement of outer winding reels 420 a and 420 c of the winding reels 420 a, 420 b, and 420 c along the rotation axis 410 is limited by stoppers 412 a and 412 b. Hereinafter, the winding reels 420 a, 420 b, and 420 c are referred to as a first winding reel, a second winding reel, and a third winding reel, respectively.
The axis support member 430 supports the rotation axis 410. The axis support member 430 may include support rods 432 and a base 434. The support rods 432 may support both ends of the rotation axis 410 to rotate and may be vertically combined with a top surface of the base 434. The axis driving part 440 may rotate the rotation axis 410 and the base driving part 450 may move the base 434 straight in the second direction. The base driving part 450 may be a linear motor. Additionally, the base driving part 450 may include a combined structure of a motor and a motive power transmission member converting a turning force of the motor into a linear driving force.
After winding of the first winding reel 420 a is completed, the carrier tape cut member 300 cuts the carrier tape T1, and the carrier tape adhesion member 100 attaches the adhesive tape T2 on the cut carrier tape T1. Thereafter, the base driving part 450 moves the base 434 straight in the second direction to align the second winding reel 420 b with the carrier tape T1 on the transfer rail 220. After the second winding reel 420 b is aligned with the carrier tape T1, the carrier tape T1 is moved toward the second winding reel 420 b, and then the carrier tape adhesion member 100 attaches the carrier tape T1 on the second winding reel 420 b. As described above, the reel replacement member 400 replaces the first winding reel 420 a where the winding of the carrier tape T1 is completed with the second winding reel 420 b. After the winding of the second winding reel 420 b is completed, the second winding reel 420 b may be replaced with the third winding reel 420 c by the same method described above.
FIG. 7 is a flowchart illustrating a detailed method of replacing a winding reel according to an example embodiment of the inventive concepts.
After the winding of the first winding reel 420 a is completed (S10), the apparatus 1 of packing the semiconductor packages illustrated in FIG. 1 operates an apparatus alarm (S20) and then the apparatus 1 interrupts a process of packing the semiconductor packages (S30). Subsequently, the carrier tape adhesion member 100 prepares the adhesive tape which will be stuck on the first winding reel 420 a (S40).
The step S40 will be described in more detail with reference to FIGS. 8A to 8D. The feeder 110 provides the adhesive tape T3. The chuck 120 chucks the end of the adhesive tape T3 to extend the adhesive tape T3 by a desired (or, alternatively a predetermined) length. (FIG. 8A) The first adhesion unit 132 picks up a left end of the desired (or, alternatively a predetermined) length of the adhesive tape T3 and the second adhesion unit 134 picks up a right end of the desired (or, alternatively a predetermined) length of the adhesive tape T3. (FIG. 8B) The adhesive tape cutter 140 cuts the adhesive tape T3 by the desired (or, alternatively a predetermined) length. (FIG. 8C) The chuck 120 releases the adhesive tape T3 and the adhesive tape cutter 140 returns to an initial position. The cut fixing tape T3 maintains a picked up state by the first and second adhesion tools 132 and 134. (FIG. 8D)
Referring to FIG. 7 again, an end of the wound carrier tape T1 is fixed on the first winding reel 420 a by using the prepared adhesive tape T3 (S50).
The step S50 will be described in more detail with reference to FIGS. 9A to 9E. The carrier tape holder 320 pressurizes and holds the carrier tape T1 wound on the first winding reel 420 a (FIG. 9A) and the carrier tape cutter 340 cuts the carrier tape T1. (FIG. 9B) The first winding reel 420 a rotates clockwise such that the cut end portion of the carrier tape T1 is located over the center of the first winding reel 420 a. At this time, the carrier tape cutter 340 returns to an initial position. (FIG. 9C) The first and second adhesion units 132 and 134 descends with picking up the adhesive tape T3 so that the first and second adhesion units 132 and 134 stick the adhesive tape T3 to the cut end portion of the carrier tape T1. At this time, the cut end portion of the carrier tape T1 is located on a center region of the adhesive tape T3. In other words, the first and second adhesion units 132 and 134 may stick the adhesive tape T3 to the cut end portion of the carrier tape T1 and the outermost wound portion of the carrier tape T1. At this time, the carrier tape holder 320 returns to an initial position. (FIG. 9D) The tape pressurization tool 150 pressurizes the adhesive tape T3 so that the adhesive tape T3 is stuck closely to the carrier tape T1. (FIG. 9E)
Referring to FIG. 7 again, the first winding reel 420 a is replaced with the second winding reel 420 b (S60) and the carrier tape adhesion member 100 prepares a adhesive tape which will be stuck on the second winding reel 420 b (S70). The step S70 may be substantially the same as the step S40. Thus, the detail description for the step S70 is omitted. A front end of the carrier tape T1, which will be wound, is attached to the second winding reel 420 b by using the prepared adhesive tape T3 (S80).
The step S80 will be described in more detail with reference to FIGS. 10 A to 10E. The guide 240 proceeds toward the second winding reel 420 b and supports the carrier tape T1 passing through the end portion of the transfer rail 220. (FIG. 10A) The first and second adhesion units 132 and 134 descend with picking up the adhesive tape T3 so that the first and second adhesion units 132 and 134 attach the adhesive tape T3 to the carrier tape T1. At this time, the front end of the carrier tape T1 is located on a center region of the fixing tape T3. In other words, the first and second adhesion units 132 and 134 attach the adhesive tape T3 to the carrier tape T1 so that a region of the carrier tape T1 is overlapped with a region of the adhesive tape T3. (FIG. 10B) The guide 240 returns to an initial position. (FIG. 10C) The first and second adhesion units 132 and 134 descends toward the second winding reel 420 b so that the first and second adhesion units 132 and 134 attach the rest region of the adhesive tape T3 that does not overlap with the carrier tape T1 to a center portion of the second winding reel 420 b (i.e., hub (not shown)). (FIG. 10D) The tape pressurization tool 150 descends toward the second winding reel 420 b so that the tape pressurization tool 150 pressurizes the adhesive tape T3 to attach the adhesive tape T3 closely to the center portion of the second winding reel 420 b (i.e., hub (not shown)). (FIG. 10E)
Referring to FIG. 7 again, the apparatus 1 of packing the semiconductor packages restarts the process packing the semiconductor packages (S90).
As described above, the apparatus 1 of packing the semiconductor packages according to example embodiments of the inventive concepts can replace the winding reels automatically. Thus, the packing process using the apparatus of packing the semiconductor packages according to the example embodiment of the inventive concepts may improve work efficiency and productivity as compared with a conventional manual packing semiconductor packages.
While example embodiments have been particularly shown and described, it will be understood by one of ordinary skill in the art that variations in form and detail may be made therein without departing from the spirit and scope of the claims. Therefore, it should be understood that the above embodiments are not limiting, but illustrative. Thus, the scope of the inventive concept is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing description.
