Description
本發明係關於一種用以將向電子零件安裝機供給電子零件之承載帶之端部連接於其他承載帶之端部的黏著帶、含有該黏著帶之承載帶之連接用膜、使用該連接用膜之承載帶之連接方法及連接承載帶。 The present invention relates to an adhesive tape for connecting an end portion of a carrier tape for supplying an electronic component to an electronic component mounting machine to an end portion of another carrier tape, a film for connection of a carrier tape including the adhesive tape, and the use of the connection The connecting method of the carrier tape of the film and the connecting carrier tape.
藉由電子零件安裝機而安裝於印刷基板上之小型電子零件主要利用如下承載帶進行搬送、保管及供給:藉由對紙基材打孔、於所得之孔中放入上述小型電子零件、並於該基材之兩表面分別貼合下膠帶與上蓋帶而形成之承載帶;或藉由於聚苯乙烯樹脂等基材上形成凹槽、於該凹槽部分放入上述小型電子零件、並利用上蓋帶進行加蓋而形成之壓紋承載帶。 The small electronic component mounted on the printed circuit board by the electronic component mounting machine is mainly transported, stored, and supplied by the following carrier tape: by punching the paper substrate, placing the small electronic component into the obtained hole, and a carrier tape formed by bonding the lower tape and the upper cover tape to the two surfaces of the substrate; or by forming a groove on the substrate such as polystyrene resin, placing the small electronic component in the groove portion, and utilizing The upper cover tape is covered with an embossed carrier tape.
晶片零件之出貨時,承載帶係於纏繞於卷盤(1卷盤長度約為20 m左右)上之狀態下供給。剝離上蓋帶,將封入之電子零件逐個取出並安裝。然後,安裝全部電子零件後,將每一卷盤切換為纏繞有新承載帶之卷盤,但若於切換時中斷安裝作業,則作業效率明顯降低,故採用如下方法,該方法係將新承載帶之端部連接於結束安裝作業之承載帶之端部,無需中斷安裝作業而切換承載帶。 At the time of shipment of the wafer component, the carrier tape is supplied in a state of being wound around the reel (1 reel has a length of about 20 m). The upper cover tape is peeled off, and the enclosed electronic components are taken out one by one and installed. Then, after installing all the electronic components, each reel is switched to a reel wrapped with a new carrier tape. However, if the installation operation is interrupted during the switching, the work efficiency is significantly reduced, so the following method is adopted, which is a new bearer. The end of the belt is connected to the end of the carrier tape that ends the installation work, and the carrier tape is switched without interrupting the installation work.
先前,為了連接新舊承載帶而使用金屬夾。然而,於使用金屬夾之情形時,存在如下問題:必需進行金屬夾之分類廢棄處理、及利用專用夾具之連接作業。 Previously, metal clips were used to connect new and old carrier tapes. However, in the case of using a metal clip, there is a problem in that it is necessary to perform a sorting and disposal process of the metal clip and a connection work using a dedicated jig.
因此,作為解決上述問題之方法,於專利文獻1中記載有如下方法:藉由分別使用不同之黏著帶將承載帶之貼附有上蓋帶之部分與除此以外之部分貼合而於不妨礙上蓋帶自基材上的剝離之情況下連接兩承載帶。然而,為了於不妨礙上蓋帶之剝離性之情況下連接兩承載帶,必需嚴格調整貼合位置,由於機械化較困難,因此由人進行人工作業。又,為了迅速貼合於準確位置,作業必需非常熟練,作業人員之熟習度會對作業效率產生較大之影響,故難以獲得固定之作業效率。進而,若為了使定位變得容易而對黏著帶實施形成虛線狀縫隙等之加工,則雖然作業效率得到一定程度的改善,但存在黏著帶之製造成本增加、黏著帶變得昂貴之問題。 Therefore, as a method for solving the above problem, Patent Document 1 discloses a method in which a portion of a carrier tape to which an upper cover tape is attached is bonded to a portion other than the other adhesive tape, and is not hindered. The upper cover tape is connected to the two carrier tapes in the case of peeling from the substrate. However, in order to connect the two carrier tapes without impeding the peelability of the upper cover tape, it is necessary to strictly adjust the bonding position, and since it is difficult to mechanize, manual work is performed by a person. Moreover, in order to quickly adhere to an accurate position, the work must be very skilled, and the familiarity of the worker has a large influence on the work efficiency, so that it is difficult to obtain a fixed work efficiency. Further, when the adhesive tape is subjected to a process of forming a broken line or the like in order to facilitate positioning, the work efficiency is improved to some extent, but the manufacturing cost of the adhesive tape is increased, and the adhesive tape becomes expensive.

因此,本發明之目的在於提供無需嚴格之定位、可容易地貼合於承載帶連接部、且不妨礙承載帶表面之上蓋帶之剝離的黏著帶。 Accordingly, it is an object of the present invention to provide an adhesive tape which can be easily attached to a carrier tape connecting portion without impeding the peeling of the cover tape on the surface of the carrier tape without strict positioning.
本發明之其他目的在於提供一種含有上述黏著帶之承載帶之連接用膜。 Another object of the present invention is to provide a film for connection comprising a carrier tape of the above adhesive tape.
本發明之進而其他目的在於提供一種使用上述承載帶連接用膜之承載帶之連接方法。 Still another object of the present invention is to provide a joining method of a carrier tape using the above-described film for connecting a carrier tape.
本發明之其他目的在於提供一種藉由上述承載帶之連接方法而連接之連接承載帶。 Another object of the present invention is to provide a connecting carrier tape that is connected by the above-described connection method of the carrier tape.
本發明者等人為了解決上述問題而進行銳意研究,結果發現:關於面之第一方向之撕裂強度及與上述第一方向正交之第二方向之撕裂強度,於將第二方向之撕裂強度設為1時,第一方向之撕裂強度未達0.75之黏著帶,由於在面之第一方向具有優異之開裂性,故若使黏著帶之易撕裂方向對準上蓋帶之剝離方向而貼合,則以纏繞於承載帶之周圍之方式貼合,即便以一條膠帶將承載帶之貼附有上蓋帶之部分與除此以外之部分貼合,於剝離上蓋帶時,亦可伴隨於上蓋帶之剝離而使黏著帶中之貼合於上蓋帶表面之部分開裂並與上蓋帶一起自承載帶表面剝離,故黏著帶不會抑制上蓋帶之剝離性;因黏著帶具有優異之開裂性而無需嚴格之定位;因即便貼合於大概位置亦不妨礙上蓋帶之剝離而無需實施於黏著帶上形成虛線狀縫隙等用以使定位變得容易之加工,可廉價地製造;可藉由人工作業進行貼合,亦可使用機械進行貼合;又,於人工作業之情形時,無論作業人員是否熟練,均可容易且迅速地進行連接作業。本發明係基於該等見解而完成者。 The inventors of the present invention conducted intensive studies to solve the above problems, and found that the tear strength in the first direction of the face and the tear strength in the second direction orthogonal to the first direction are in the second direction. When the tear strength is set to 1, the adhesive tape having a tear strength of less than 0.75 in the first direction has excellent cracking property in the first direction of the surface, so that the easy tearing direction of the adhesive tape is aligned with the upper cover tape. When it is bonded in the peeling direction, it is attached so as to be wound around the carrier tape, and even if a portion of the carrier tape to which the upper cover tape is attached is bonded to the other portion by a tape, when the cover tape is peeled off, The peeling of the upper cover tape may cause the portion of the adhesive tape to be adhered to the surface of the upper cover tape to be cracked and peeled off from the surface of the carrier tape together with the upper cover tape, so that the adhesive tape does not inhibit the peelability of the upper cover tape; Cracking without strict positioning; even if it is attached to the approximate position, it does not hinder the peeling of the upper cover tape, and it is not necessary to form a dotted-line slit on the adhesive tape to make the positioning easy, and it is inexpensive.

Moreover, mechanization can also be utilized. Further, when the film for connection of the carrier tape of the present invention is used, the carrier tape can be switched without interrupting the mounting work, so that the work efficiency can be prevented from being lowered, and the mounting work can be continuously performed with excellent workability. Further, since the film for connection of the carrier tape of the present invention does not need to be processed for improving the positioning property, the manufacturing cost can be reduced, and it can be provided at low cost.
本發明之黏著帶於基材之其中一面具有黏著劑層。 The adhesive tape of the present invention has an adhesive layer on one side of the substrate.
作為基材,例如可列舉:聚酯(聚對苯二甲酸乙二酯(PET,Polyethylene terephthalate)、聚萘二甲酸乙二酯、聚對苯二甲酸丁二酯、聚萘二甲酸丁二酯等)、聚烯烴(聚乙烯、聚丙烯(PP,Polypropylene)、乙烯-丙烯共聚物等)、聚乙烯醇、聚偏二氯乙烯、聚氯乙烯、氯乙烯-乙酸 乙烯酯共聚物、聚乙酸乙烯酯、聚醯胺、聚醯亞胺、纖維素類、氟系樹脂、聚醚、聚醚醯胺、聚苯硫醚、聚苯乙烯系樹脂(聚苯乙烯等)、聚碳酸酯、聚醚碸等塑膠系基材。 Examples of the substrate include polyester (polyethylene terephthalate (PET), polyethylene naphthalate, polybutylene terephthalate, and polybutylene naphthalate. Etc.), polyolefin (polyethylene, polypropylene (PP, Polypropylene), ethylene-propylene copolymer, etc.), polyvinyl alcohol, polyvinylidene chloride, polyvinyl chloride, vinyl chloride-acetic acid Vinyl ester copolymer, polyvinyl acetate, polyamide, polyimine, cellulose, fluorine resin, polyether, polyether decylamine, polyphenylene sulfide, polystyrene resin (polystyrene, etc.) ), polycarbonate, polyether oxime and other plastic substrates.
於本發明中,其中就容易獲得、具有充分之強度、且直線切割性優異之方面而言,較佳為使用聚烯烴膜(尤其是聚丙烯膜)、聚酯膜等基材。 In the present invention, a substrate such as a polyolefin film (particularly a polypropylene film) or a polyester film is preferably used in terms of easy availability, sufficient strength, and excellent linear cuttability.
又,對於基材之表面,為了提高與黏著劑層之密接性,可視需要施加慣用之表面處理,例如鉻酸處理、臭氧暴露、火焰暴露、高壓電擊暴露、離子化輻射處理等利用化學或物理方法進行之氧化處理等。 Further, for the surface of the substrate, in order to improve the adhesion to the adhesive layer, it is possible to apply a conventional surface treatment such as chromic acid treatment, ozone exposure, flame exposure, high-voltage electric shock exposure, ionizing radiation treatment, etc. using chemical or physical means. The method is oxidized and the like.
本發明之基材較佳為,關於面之第一方向之撕裂強度及與上述第一方向正交之第二方向之撕裂強度,於將第二方向之撕裂強度設為1時,第一方向之撕裂強度未達0.75(較佳為0.10以上、未達0.75左右,尤佳為0.50以上、未達0.75)。 Preferably, the substrate of the present invention has a tear strength in a first direction with respect to a surface and a tear strength in a second direction orthogonal to the first direction, and when the tear strength in the second direction is set to 1, The tear strength in the first direction is less than 0.75 (preferably 0.10 or more, not more than 0.75, particularly preferably 0.50 or more and less than 0.75).
再者,所謂「面之第一方向」,係基材之具有易撕裂性之方向,例如主延伸方向。本發明之撕裂強度係以撕裂所需之力表示,數值越小,則表示越容易撕裂。本發明之撕裂強度可藉由依據JIS K7128(1998年)之Elmendorf撕裂試驗而測定。若面之第一方向之撕裂強度與第二方向之撕裂強度之比為0.75以上,則有如下傾向:開裂性變得不充分,連接承載帶後剝離上蓋帶時,因連結部而使剝離中斷,難以連續進行安裝作業。 Further, the "first direction of the surface" is a direction in which the substrate has tearability, for example, a main direction of extension. The tear strength of the present invention is expressed by the force required for tearing, and the smaller the value, the easier it is to tear. The tear strength of the present invention can be measured by an Elmendorf tear test in accordance with JIS K7128 (1998). When the ratio of the tear strength in the first direction to the tear strength in the second direction is 0.75 or more, the cracking property is insufficient, and when the upper cover tape is peeled off after the carrier tape is attached, the joint portion is used. The peeling is interrupted, making it difficult to perform the installation work continuously.
面之第一方向之撕裂強度與第二方向之撕裂強度之比例 如可藉由控制朝各方向之延伸倍率而調整。 The ratio of the tear strength in the first direction to the tear strength in the second direction It can be adjusted by controlling the stretching ratio in all directions.
作為基材之厚度,例如,較佳為10~100 μm左右,更佳為10~50 μm左右,最佳為10~30 μm左右。若基材之厚度低於上述範圍,則有黏著帶之強度不足、損及實用性之虞。另一方面,若基材之厚度高於上述範圍,則有朝向面之第一方向之開裂性降低之傾向,且有難以向承載帶纏繞之傾向。又,亦有安裝機(貼片機:料架)上之移行性惡化之虞。 The thickness of the substrate is, for example, preferably about 10 to 100 μm, more preferably about 10 to 50 μm, and most preferably about 10 to 30 μm. When the thickness of the base material is less than the above range, the strength of the adhesive tape is insufficient, and the practicality is impaired. On the other hand, when the thickness of the base material is more than the above range, the cracking property in the first direction toward the surface tends to be lowered, and the carrier tape tends to be entangled. In addition, there is also a deterioration in the mobility of the mounting machine (mounting machine: rack).
作為構成本發明之黏著帶之黏著劑層之黏著劑(基礎聚合物),例如可列舉丙烯酸系黏著劑、橡膠系黏著劑、及矽酮系黏著劑。該等可單獨或混合兩種以上而使用。 Examples of the adhesive (base polymer) constituting the pressure-sensitive adhesive layer of the adhesive tape of the present invention include an acrylic pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, and an anthrone-based pressure-sensitive adhesive.

進而又,作為承載帶連接用黏著帶之180°剝離黏著力(相對於紙基材、剝離溫度:25℃、剝離速度:300 mm/min)與180°剝離黏著力(相對於聚對苯二甲酸乙二酯膜、剝離溫度:25℃、剝離速度:300 mm/min)的比(前者/後者),例如為0.3以上,較佳為0.5以上,尤佳為0.8以上。若承載帶連接用黏著帶之相對於聚對苯二甲酸乙二酯膜之黏著力與相對於紙基材之黏著力的比低於上述範圍,則連接承載帶後剝離上蓋帶時,存在剝離中斷而難以連續進行安裝作業之情形。承載帶連接用黏著帶之180°剝離黏著力例如可藉由控制黏著劑層厚度、構成黏著劑層之黏著劑之組成等而調整。 Further, as a carrier tape for the carrier tape connection, the 180° peeling adhesive force (relative to the paper substrate, peeling temperature: 25° C., peeling speed: 300 mm/min) and 180° peeling adhesion force (relative to polyparaphenylene) The ratio (the former/the latter) of the ethylene formate film, the peeling temperature: 25 ° C, and the peeling speed: 300 mm/min) is, for example, 0.3 or more, preferably 0.5 or more, and particularly preferably 0.8 or more. If the ratio of the adhesive force of the adhesive tape for the carrier tape to the polyethylene terephthalate film to the adhesive force with respect to the paper substrate is less than the above range, the peeling of the upper cover tape after the carrier tape is attached may be peeled off. Interrupted and difficult to perform continuous installation work. The 180° peeling adhesive force of the adhesive tape for the carrier tape can be adjusted, for example, by controlling the thickness of the adhesive layer, the composition of the adhesive constituting the adhesive layer, and the like.
本發明之基礎膜係用於承載帶連接用黏著帶之黏著劑層面之保護、黏連之防止、連續型承載帶連接用膜之輥狀保 持、單片型或單片化之連續型承載帶連接用膜之形狀保持等,於將承載帶連接用黏著帶貼附於承載帶之連接部前將其剝離。 The base film of the present invention is used for the protection of the adhesive layer for carrying the adhesive tape for connection, the prevention of adhesion, and the roll protection of the film for continuous carrier tape connection. The shape of the film for continuous carrier tape connection of the holding, the one-piece type or the singulation is maintained, and the adhesive tape for the carrier tape is peeled off before being attached to the connection portion of the carrier tape.
作為基礎膜,並無特別限定,可使用公知慣用之剝離紙(分隔件)等,例如可使用:包含藉由矽酮系、長鏈烷基系、氟系、硫化鉬系等剝離劑進行表面處理之塑膠膜或紙等剝離層之基材;含有聚四氟乙烯、聚氯三氟乙烯、聚氟乙烯、聚偏二氟乙烯、四氟乙烯-六氟丙烯共聚物、氯氟乙烯-偏二氟乙烯共聚物等氟系聚合物之低接著性基材;含有烯烴系樹脂(例如聚乙烯、聚丙烯等)等無極性聚合物之低接著性基材等。 The base film is not particularly limited, and a known release paper (separator) or the like can be used. For example, a release sheet containing an anthrone, a long-chain alkyl group, a fluorine-based or a molybdenum sulfide-based release agent can be used. a substrate for treating a peeling layer such as a plastic film or paper; containing polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinyl fluoride, polyvinylidene fluoride, tetrafluoroethylene-hexafluoropropylene copolymer, chlorofluoroethylene-bias A low-adhesive base material of a fluorine-based polymer such as a difluoroethylene copolymer; a low-adhesive base material containing a nonpolar polymer such as an olefin resin (for example, polyethylene or polypropylene).
基礎膜之厚度例如為16~300 μm左右,其中較佳為90~150 μm,尤佳為95~130 μm。若基礎膜之厚度低於上述範圍,則強度變得不充分,故有如下傾向:於承載帶之連接用膜上容易產生皺褶,難以防止折褶,難以貼合於承載帶之連接部。另一方面,若基礎膜之厚度高於上述範圍,則有難以捲取為輥狀之傾向,又,有基礎膜之排斥性變得過強、容易自承載帶連接用黏著帶剝離之傾向。 The thickness of the base film is, for example, about 16 to 300 μm, preferably 90 to 150 μm, and particularly preferably 95 to 130 μm. When the thickness of the base film is less than the above range, the strength is insufficient. Therefore, there is a tendency that wrinkles are likely to occur on the film for connection of the carrier tape, and it is difficult to prevent creases, and it is difficult to bond the joint portion of the carrier tape. On the other hand, when the thickness of the base film is higher than the above range, it tends to be difficult to be wound into a roll shape, and the repellency of the base film is too strong, and it tends to be peeled off from the adhesive tape for carrier tape connection.
作為基礎膜之形狀,並無特別限制。與承載帶之傳送孔相對應之孔可有可無。 The shape of the base film is not particularly limited. The hole corresponding to the transfer hole of the carrier tape may or may not be included.
本發明之轉貼膠帶係於將承載帶連接用黏著帶貼合於承載帶之連接部時,具有防止承載帶連接用黏著帶產生皺褶而使貼合變得容易,並且使承載帶連接用黏著帶向承載帶 之背面之彎折變得容易之作用,於將承載帶連接用黏著帶貼附於承載帶之連接部後將其剝離。 When the adhesive tape of the present invention is attached to the connecting portion of the carrier tape, the adhesive tape of the present invention has a wrinkle which prevents the adhesive tape for the carrier tape from being attached, thereby facilitating the bonding, and bonding the carrier tape. Belt bearing belt The bending of the back surface becomes easy, and the adhesive tape for connecting the carrier tape is attached to the connecting portion of the carrier tape and then peeled off.
轉貼膠帶具有於基材之一側包含黏著劑層之結構。作為轉貼膠帶之基材,可列舉與上述承載帶連接用黏著帶之基材相同之例。 The transfer tape has a structure in which an adhesive layer is provided on one side of the substrate. The base material of the transfer tape may be the same as the base material of the above-mentioned adhesive tape for carrier tape connection.
為了提高與黏著劑層等之密接性,可視需要對轉貼膠帶之基材之表面實施慣用之表面處理,例如,鉻酸處理、臭氧暴露、火焰暴露、高壓電擊暴露、離子化輻射處理等利用化學或物理方法進行之氧化處理等。 In order to improve the adhesion to the adhesive layer and the like, it is possible to perform a conventional surface treatment on the surface of the substrate on which the tape is transferred, for example, chromic acid treatment, ozone exposure, flame exposure, high-voltage shock exposure, ionizing radiation treatment, etc. Or oxidation treatment by physical methods.
作為轉貼膠帶之基材之厚度,例如為16~125 μm左右,其中較佳為25~85 μm,尤佳為38~75 μm,最佳為45~70 μm。若基材之厚度低於上述範圍,則強度不足,將承載帶連接用黏著帶貼合於承載帶之連接部時難以防止皺褶之產生,連接承載帶後剝離上蓋帶時,存在剝離中斷而難以連續進行安裝作業之情形。又,於將承載帶連接用黏著帶貼合於承載帶之連接部後剝離轉貼膠帶時,有難以剝離之傾向。另一方面,若基材之厚度高於上述範圍,則有承載帶連接用黏著帶向承載帶之背面之彎折變得困難之傾向,除此以外,有體積變大而作業性降低之傾向。 The thickness of the substrate as the transfer tape is, for example, about 16 to 125 μm, preferably 25 to 85 μm, more preferably 38 to 75 μm, and most preferably 45 to 70 μm. When the thickness of the base material is less than the above range, the strength is insufficient, and it is difficult to prevent the occurrence of wrinkles when the adhesive tape for the carrier tape is attached to the joint portion of the carrier tape, and the peeling is interrupted when the upper cover tape is peeled off after the carrier tape is attached. It is difficult to carry out the installation work continuously. Further, when the adhesive tape for connecting the carrier tape is bonded to the connection portion of the carrier tape and the transfer tape is peeled off, it tends to be difficult to peel off. On the other hand, when the thickness of the base material is more than the above range, the adhesive tape for connecting the belt tends to be bent toward the back surface of the carrier tape, and the volume tends to be large, and the workability tends to be lowered.
作為轉貼膠帶之黏著劑層,可列舉與上述承載帶連接用黏著帶之黏著劑層相同之例。 The adhesive layer of the transfer tape may be the same as the adhesive layer of the adhesive tape for the carrier tape.
轉貼膠帶之黏著劑層之厚度例如為6~12 μm左右,其中較佳為7~11 μm,尤佳為8~10 μm。若黏著劑層之厚度低於上述範圍,則有接著力降低而難以保持承載帶連接用黏著 帶之傾向。另一方面,若黏著劑層之厚度高於上述範圍,則對承載帶連接用黏著帶之黏著力變得過強,有將承載帶連接用黏著帶貼合於承載帶連接部後,難以剝離轉貼膠帶之傾向。 The thickness of the adhesive layer of the transfer tape is, for example, about 6 to 12 μm, preferably 7 to 11 μm, and more preferably 8 to 10 μm. If the thickness of the adhesive layer is lower than the above range, there is a decrease in the adhesion force and it is difficult to maintain the adhesion of the carrier tape connection. The tendency to bring. On the other hand, when the thickness of the adhesive layer is higher than the above range, the adhesive force to the adhesive tape for carrier tape connection becomes too strong, and it is difficult to peel off the adhesive tape for connecting the carrier tape after being bonded to the carrier tape connection portion. The tendency to transfer tape.
又,轉貼膠帶具有弱黏著力,其180°剝離黏著力(相對於SUS板、剝離溫度:25℃、剝離速度:300 mm/min)例如為0.02 N/25 mm以上(較佳為0.03~0.70 N/25 mm,尤佳為0.04~0.20 N/25 mm)。若轉貼膠帶之180°剝離黏著力(相對於SUS板、剝離溫度:25℃、剝離速度:300 mm/min)低於上述範圍,則難以保持承載帶連接用黏著帶,將承載帶連接用黏著帶貼合於承載帶之連接部時,有作業性降低之傾向。另一方面,若轉貼膠帶之180°剝離黏著力(相對於SUS板、剝離溫度:25℃、剝離速度:300 mm/min)高於上述範圍,則將承載帶連接用黏著帶貼合於承載帶之連接部後,難以僅將轉貼膠帶剝離,連接承載帶後剝離上蓋帶時,存在剝離中斷而難以連續進行安裝作業之情形。 Further, the transfer tape has a weak adhesive force, and its 180° peeling adhesive force (relative to the SUS plate, peeling temperature: 25° C., peeling speed: 300 mm/min) is, for example, 0.02 N/25 mm or more (preferably 0.03 to 0.70). N/25 mm, especially preferably 0.04~0.20 N/25 mm). If the 180° peeling adhesive force of the transfer tape (relative to SUS plate, peeling temperature: 25° C., peeling speed: 300 mm/min) is lower than the above range, it is difficult to maintain the adhesive tape for connecting the carrier tape, and the carrier tape is bonded to the adhesive tape. When the tape is attached to the joint portion of the carrier tape, the workability tends to be lowered. On the other hand, if the 180° peeling adhesive force (relative to the SUS plate, peeling temperature: 25° C., peeling speed: 300 mm/min) of the tape is higher than the above range, the adhesive tape for the carrier tape is attached to the carrier. After the connection portion of the belt, it is difficult to peel only the transfer tape, and when the carrier tape is attached and the upper cover tape is peeled off, peeling is interrupted and it is difficult to continuously perform the mounting work.
作為轉貼膠帶之形狀,只要為可提高上述承載帶連接用黏著帶於承載帶之連接部之貼合作業性之形狀,則並無特別限定,為了使操作性提高及定位變得容易,較佳為於轉貼膠帶中具有上述承載帶連接用黏著帶未貼附之部分(以下有時稱為「連結部」),就提高貼合作業之方面而言,較佳為於該連結部上具有與承載帶之傳送孔相對應之孔。就只要使轉貼膠帶之長度方向對準承載帶連接用黏著帶之邊(第一方向),則無論貼合於左右任一側均可使用,且作 業性更優異之方面而言,作為承載帶連接用黏著帶為連結型之情形時之轉貼膠帶之形狀較佳為具有與承載帶之傳送孔相對應之第1孔且於介隔寬度方向之中心線而與上述第1孔對稱之位置具有第2孔。再者,單片型承載帶之連接用膜未必具有與承載帶之傳送孔相對應之孔。 The shape of the transfer tape is not particularly limited as long as it can improve the adhesion of the adhesive tape for the carrier tape to the connection portion of the carrier tape, and it is preferable to improve the operability and the positioning. In order to improve the bonding work, it is preferable that the adhesive tape has a portion to which the adhesive tape for the carrier tape connection is not attached (hereinafter referred to as a "joining portion"). The hole corresponding to the conveying hole of the carrying belt. As long as the length direction of the transfer tape is aligned with the side of the adhesive tape for the carrier tape connection (the first direction), it can be used regardless of whether it is attached to either of the left and right sides, and In the case where the adhesiveness of the carrier tape is a connection type, the shape of the transfer tape preferably has a first hole corresponding to the transfer hole of the carrier tape and is in the width direction of the spacer. The center line has a second hole at a position symmetrical with the first hole. Further, the film for connection of the one-piece type carrier tape does not necessarily have a hole corresponding to the transfer hole of the carrier tape.
進而又,就使承載帶連接用黏著帶向承載帶之背面之彎折變得更容易,且於連接承載帶後剝離轉貼膠帶時,可藉由受到承載帶連接用黏著帶表面排斥而提高剝離性之方面而言,較佳為於連結部具有「剜口」。於承載帶連接用黏著帶為連結型之情形時,藉由連結部具有「剜口」,亦有可減小承載帶連接用黏著帶之連結部分並可使單片化變得容易之優勢。作為本發明之轉貼膠帶之具體例,例如可列舉具有如圖4所示之形狀之轉貼膠帶等。 Further, it is easier to bend the adhesive tape for the carrier tape to the back surface of the carrier tape, and when the transfer tape is peeled off after the carrier tape is attached, the peeling property can be improved by being repelled by the surface of the adhesive tape for the carrier tape connection. In terms of the aspect, it is preferable that the connecting portion has a "mouth". In the case where the adhesive tape for the carrier tape connection is a connection type, the connection portion has a "mouth", and the connection portion of the adhesive tape for the carrier tape connection can be reduced, and the singulation can be facilitated. Specific examples of the transfer tape of the present invention include a transfer tape having a shape as shown in Fig. 4 and the like.
作為轉貼膠帶之長度方向「剜口」間隔(w3),就可容易地進行貼合作業之方面而言,較佳為與承載帶連接用黏著帶之邊(第一方向)之長度(w1)大致相同,例如為20~100 mm左右,較佳為30~50 mm。 As the length of the transfer tape, the "mouth" interval (w3) is easy to perform the bonding work, and preferably the length (w1) of the side (first direction) of the adhesive tape for connecting the tape. It is roughly the same, for example, about 20 to 100 mm, preferably 30 to 50 mm.
作為轉貼膠帶之寬度(w4),就可容易地進行貼合作業之方面而言,較佳為與承載帶連接用黏著帶之邊(第二方向)之長度(w2)大致相同,例如為8.0~17.5 mm左右。 As the width (w4) of the transfer tape, it is preferable that the length (w2) of the side (second direction) of the adhesive tape for connecting the carrier tape is substantially the same, for example, 8.0. ~17.5 mm or so.
作為與承載帶之傳送孔相對應之孔之位置,較佳為自寬度方向之中心線至孔之中心為止之距離(w5)為例如2.0~5.0 mm左右。 The position of the hole corresponding to the transfer hole of the carrier tape is preferably a distance (w5) from the center line in the width direction to the center of the hole, for example, about 2.0 to 5.0 mm.
作為「剜口」之形狀,並無特別限定,例如可列舉直徑 (w7)4.2~10 mm左右之半圓形狀、凹型形狀、三角形狀等。又,自寬度方向中心線至「剜口」外周為止之長度(w6)例如為2.5~7.5 mm左右。 The shape of the "mouth" is not particularly limited, and examples thereof include a diameter. (w7) Semicircular shape, concave shape, triangular shape, etc. of about 4.2 to 10 mm. Further, the length (w6) from the center line in the width direction to the outer circumference of the "mouth" is, for example, about 2.5 to 7.5 mm.
本發明之承載帶之連接方法之特徵在於:將上述承載帶之連接用膜之基礎膜剝離,對於所得之承載帶連接用黏著帶/轉貼膠帶積層體,於使承載帶連接用黏著帶之面之第一方向對準承載帶之長度方向之狀態下,使承載帶連接用黏著帶之黏著劑層面朝向承載帶連接部而纏繞,其後剝離轉貼膠帶。藉由本發明之承載帶之連接方法,連接承載帶後剝離上蓋帶時,可於不在連接部分剝離中斷之情況下順利地將上蓋帶剝離,可連續進行安裝作業。 The method for joining a carrier tape according to the present invention is characterized in that the base film of the film for connection of the carrier tape is peeled off, and the adhesive tape/transfer tape laminated body for the carrier tape is connected to the surface of the adhesive tape for connecting the carrier tape. When the first direction is aligned with the longitudinal direction of the carrier tape, the adhesive layer of the adhesive tape for the carrier tape is wound toward the carrier tape connecting portion, and then the transfer tape is peeled off. According to the connecting method of the carrier tape of the present invention, when the carrier tape is attached and the upper cover tape is peeled off, the upper cover tape can be smoothly peeled off without being interrupted by the connection portion, and the mounting work can be continuously performed.
作為本發明之承載帶之連接方法,較佳為包括下述步驟(I)~(V)。再者,使用單片型作為承載帶之連接用膜之情形時,可省略下述步驟(I)。 As a method of connecting the carrier tape of the present invention, it is preferred to include the following steps (I) to (V). Further, in the case where a monolithic type is used as the film for connection of the carrier tape, the following step (I) can be omitted.
(I)切割承載帶之連接用膜而使其單片化;(II)剝離單片化之承載帶之連接用膜之基礎膜;(III)將所得之承載帶連接用黏著帶/轉貼膠帶積層體貼合於承載帶連接部;(IV)將承載帶連接用黏著帶/轉貼膠帶積層體纏繞於承載帶連接部;(V)剝離轉貼膠帶。 (I) cutting the film for connection of the carrier tape to be singulated; (II) peeling off the base film of the film for connection of the singulated carrier tape; (III) attaching the adhesive tape/transfer tape for the obtained carrier tape The laminated body is attached to the carrier tape connecting portion; (IV) the carrier tape connecting adhesive tape/transferring tape laminated body is wound around the carrier tape connecting portion; (V) the peeling transfer tape is peeled off.
上述步驟(I)中,連結型承載帶之連接用膜係於切割而單片化後用於承載帶之連接。作為連結型承載帶之連接用膜 之切割處,只要為不切割承載帶連接用黏著帶處(即,連結部),則並無特別限定,就可提高於承載帶之連接部上之貼合作業性之方面而言,較佳為在可獲得包含至少1個與承載帶之傳送孔相對應之孔的經單片化之承載帶之連接用膜處切割。 In the above step (I), the film for connection of the connection type carrier tape is used for the connection of the carrier tape after being diced and diced. Connecting film as a connecting type carrier tape The cut portion is not particularly limited as long as it is an adhesive tape for connecting the carrier tape (that is, the joint portion), and is preferably improved in terms of the workability on the joint portion of the carrier tape. The film is cut at the film for connection of the singulated carrier tape which can obtain at least one hole corresponding to the transfer hole of the carrier tape.
上述步驟(III)中,較佳為於以使轉貼膠帶之與承載帶之傳送孔相對應之孔與承載帶之傳送孔對準之方式配置之狀態下貼合。又,於承載帶連接用黏著帶之2條邊(第二方向)同時具有切口之情形時,只要使承載帶連接用黏著帶之面之第一方向對準承載帶之長度方向而貼合即可,於僅相對之邊(第二方向)之一具有切口之情形時,較佳為使承載帶連接用黏著帶之面之第一方向對準承載帶之長度方向,且於上蓋帶之撕裂起始點一側配置具有切口之邊(第二方向)而貼合。 In the above step (III), it is preferable to bond in a state in which the hole corresponding to the transfer hole of the transfer tape is aligned with the transfer hole of the carrier tape. Further, when the two sides (second direction) of the adhesive tape for carrying the belt are simultaneously provided with the slit, the first direction of the surface of the adhesive tape for the carrier tape is aligned with the longitudinal direction of the carrier tape. In the case where only one of the opposite sides (the second direction) has a slit, it is preferable that the first direction of the surface of the adhesive tape for the carrier tape is aligned with the length direction of the carrier tape, and the upper cover tape is torn. The side of the starting point is placed with the side of the slit (the second direction) and fitted.
作為本發明之承載帶之連接方法之具體之一例,可列舉圖5(使用連續型承載帶之連接用膜之紙基材之承載帶的連接方法)所記載之方法等。又,本發明之承載帶之連接用膜亦可與紙基材之承載帶之情形同樣地用於壓紋承載帶之連接。於為壓紋承載帶之情形時,較佳為將承載帶連接用黏著帶/轉貼膠帶積層體貼合於承載帶連接部後,於纏繞之步驟中避開凸起部而纏繞(圖6)。 As a specific example of the connection method of the carrier tape of the present invention, the method described in FIG. 5 (the method of connecting the carrier tape of the paper substrate using the film for connection of the continuous carrier tape) may be mentioned. Further, the film for connection of the carrier tape of the present invention can also be used for the connection of the embossed carrier tape as in the case of the carrier tape of the paper substrate. In the case of the embossed carrier tape, it is preferable to attach the adhesive tape/transfer tape laminating body for the carrier tape to the carrier tape connecting portion, and then wrap around the convex portion in the winding step (FIG. 6).
藉由本發明之承載帶之連接方法,可獲得包含承載帶/承載帶連接用黏著帶積層體之連接承載帶。由於連接承載帶藉由本發明之承載帶連接用黏著帶而連接2條承載帶, 故不存在伴隨於上蓋帶之剝離而承載帶連接用黏著帶開裂、連接部妨礙上蓋帶之剝離之情況(參照圖5(VI))。因此,可連續進行安裝作業。 According to the connecting method of the carrier tape of the present invention, a connecting carrier tape comprising a carrier tape/carrier tape connecting adhesive layer laminate can be obtained. Since the connecting carrier tape is connected to the two carrier tapes by the adhesive tape for connecting the carrier tape of the present invention, Therefore, there is no case where the adhesive tape for the carrier tape is cracked due to the peeling of the upper cover tape, and the connection portion prevents the peeling of the upper cover tape (see Fig. 5 (VI)). Therefore, the installation work can be performed continuously.
