Description

球搭載用遮罩以及其製造方法Ball mounting mask and method for producing the same

本發明係關於一種用於搭載導電性球之球搭載用遮罩以及其製造方法。The present invention relates to a ball mounting mask for mounting conductive balls and a method for manufacturing the same.

在球搭載用遮罩中，當作防止用於固定被設於基板等被搭載對象物的電極上之導電性球之助焊劑等，附著於遮罩內面之情事之目的，係使用於遮罩本體的內側，而且，形成有導電性球所通過之多數開口部之開口圖形周邊，形成有凹部之球搭載用遮罩。形成此凹部之方法，有例如在板厚較厚之遮罩本體的內側，抑制包圍開口圖形之凹部的緣部之電鍍突出之遮罩係被知曉（例如參照專利文獻1）。又，其他之球搭載用遮罩，也有使用並非於膜厚較厚之遮罩本體的內側，形成凹部之方法，而在遮罩本體的內側，使分離獨立之圓柱形或橢圓形之突起部，形成多數個之方法（例如參照專利文獻2）。 [專利文獻]In the mask for ball mounting, it is used for the purpose of preventing a flux or the like for fixing conductive balls provided on electrodes of objects to be mounted, such as a substrate, from adhering to the inner surface of the mask. In the inner side of the cover body, the periphery of the opening pattern of many openings through which the conductive balls pass, and the ball-mounting cover with recesses are formed. As a method of forming such a recess, for example, a mask which suppresses the protrusion of the plating on the edge of the recess surrounding the opening pattern on the inner side of the mask body having a relatively thick plate thickness is known (for example, refer to Patent Document 1). In addition, in other ball-mounting masks, instead of forming a concave portion on the inner side of the mask body with a relatively thick film thickness, separate cylindrical or elliptical protrusions are used on the inner side of the mask body. , a method of forming a plurality of them (for example, refer to Patent Document 2). [Patent Literature]

［專利文獻1］日本特開2010-247500號公報 〔專利文獻2〕日本特開2017-5023號公報[Patent Document 1] Japanese Patent Application Laid-Open No. 2010-247500 [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-5023

在先前之專利文獻1所述之球搭載用遮罩中，係形成有凹部，使得以較厚之電鍍皮膜，完全包圍開口圖形周邊，所以，有水平方向之張力不施加於開口圖形周邊的凹部，在重要之開口圖形部產生撓曲或變形，變得較容易產生搭載不良之問題。又，在此製造方法中，係必須於工序中，為了在進行二次電鍍之前，形成凹部，而去除成為不需要之開口圖形部的一次電鍍電著層之工序（捨棄電鍍去除工序），但是，必須於複數個之各開口圖形，去除成為不需要之一次電鍍電著層，所以，為了適應量產而有時很費工時，而較難採用於量產。又，在專利文獻2所述之球搭載用遮罩中，在組裝到版框時，當由紗網所引起之張力施加於遮罩本體時，分離獨立之突起部可往力量施加之方向位移，所以，具有張力也作用於開口圖形部，在開口圖形部較難產生變形，被維持於水平方向之優點，但是，在其反面，因為遮罩本體的大部分係成為較薄之構造，所以，具有當作遮罩之耐久性，或因為施加於遮罩之張力，而較容易產生開口圖形部之經時變形或位置精度之偏移之問題。In the ball mounting mask described in the previous Patent Document 1, the recessed portion is formed so that the periphery of the opening pattern is completely surrounded by a thick plating film, so that there is a recessed portion in which horizontal tension is not applied to the periphery of the opening pattern. , flexing or deformation occurs in the important opening pattern part, and it becomes easier to cause the problem of poor mounting. In addition, in this manufacturing method, in the process, in order to form the recessed portion before the secondary plating, the process of removing the primary electroplating layer that becomes the unneeded opening pattern portion is necessary (the electroplating removal process is discarded), but , it is necessary to remove the unnecessary one-time electroplating layer in each opening pattern. Therefore, in order to adapt to mass production, it is sometimes very labor-intensive, and it is difficult to use in mass production. In addition, in the ball-mounting mask described in Patent Document 2, when a tension force caused by the gauze is applied to the mask body during assembly to the plate frame, the separate projections can be displaced in the direction in which the force is applied. , therefore, the tension also acts on the opening pattern portion, and the opening pattern portion is difficult to deform and is maintained in the horizontal direction. However, on the opposite side, since most of the mask body has a thinner structure, , it has the durability of being used as a mask, or because of the tension applied to the mask, it is more likely to cause the problem of time deformation of the opening pattern part or deviation of the position accuracy.

本發明係為了解決如上述之課題所研發出者，其目的係在於提供一種在用於使遮罩內面之厚膜較厚之凸部，分離獨立之鄰接之開口圖形部間，形成膜厚般薄之凹槽，使得不以較厚之電鍍皮膜，完全包圍開口圖形部周邊，水平方向之張力作用於開口圖形部，以持續控制開口圖形部之變形或鬆弛，實現提高當作遮罩之耐久性，與開口圖形部之位置精度之球搭載用遮罩以及其製造方法。The present invention has been developed in order to solve the above-mentioned problems, and its object is to provide a convex portion for making the thick film on the inner surface of the mask thicker and the adjacent opening pattern portions separated and independent to form a film thickness. The thin groove makes it impossible to completely surround the periphery of the opening pattern with a thicker electroplating film. The tension in the horizontal direction acts on the opening pattern to continuously control the deformation or relaxation of the opening pattern, so as to improve the performance of the mask.

藉圖5說明本發明之實施例1中之球搭載用遮罩之製造方法。首先，貼合感光膜到不銹鋼母材6上，進行需要之曝光及顯影處理，於不銹鋼母材6上，局部性地形成凸部形成用之感光膜層7（參照圖5（a））。而且，雖然在本發明之專利說明書中，係使用底片式感光膜，但是，使用之感光膜也可以係液體感光膜。此凸部形成用之感光膜層7，雖然係例如突條、線狀等，但是，也可以係多角形等，並不侷限於突條、線狀。接著，藉電鍍於不銹鋼母材6上的全體，而例如形成一次電鍍層8，使得厚度成為約20～30μm（參照圖5（b））。此時，被形成之一次電鍍層8，係被分為一次殘留電鍍部分8a及一次捨棄電鍍部分8b，一次殘留電鍍部分8a係成為分離獨立之複數之凸部5的基礎（基底），一次捨棄電鍍部分8b係在下一工序中，被剝離以去除。而且，如果一次電鍍層8之形成結束後，去除凸部形成用之感光膜層7（參照圖5（c））。而且，在此狀態中，當俯視時，彼此鄰接之四角形之開口圖形部3，係藉在上下左右之四邊之各中央部，往上下垂直方向及左右水平方向延伸之連結凹槽4而被連結，此四角形之開口圖形部3與連結凹槽4，係彼此被連結為一連串，藉此，一次電鍍層8係可一次全部，僅剝離成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a以外之被剝離去除之一次捨棄電鍍部分8b（參照圖5（d））。接著，全部去除成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a以外的一次捨棄電鍍部分8b，在不銹鋼母材6上，僅殘留成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a，形成由第1電鍍層所構成之厚度約20～30μm之內部凸部（參照圖5（e））。而且，雖然省略圖示及詳細說明，但是，於不銹鋼母材6上之四角形之開口圖形部3之形成位置，貼合周知之開口部形成用之感光膜，進行圖形曝光及顯影等之處理，形成導電性球所通過之開口部2用之感光膜。接著，電鍍於不銹鋼母材6上及成為分離獨立之複數凸部的基礎（基底）之一次殘留電鍍部分8a上，使得遮罩本體成為指定之厚度，例如約30μm，藉此，形成二次電鍍層9（參照圖5（f））。藉此，形成由覆蓋內部凸部的外周全表面之第2電鍍層所構成之外部凸部。最後，自不銹鋼母材6剝離遮罩本體，該遮罩本體係包括成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a、及由二次電鍍層9所構成之四角形之開口圖形部3、及被形成為比連結凹槽4還要厚（例如厚度50～60μm）之彼此分離獨立之複數之凸部5（參照圖5（g））。藉此，完成球搭載用遮罩，該球搭載用遮罩係包括被形成為比本發明之四角形之開口圖形部3及連結凹槽4還要厚之彼此分離獨立之複數之凸部5。形成有導電性球所貫穿之複數之開口部2a之四角形之開口圖形部3，係球搭載領域。而且，完成之球搭載用遮罩1之分離獨立之複數之凸部5的尖端部，係其周緣邊緣部不成為角形，而成為具有圓度之R形。Referring to FIG. 5 , a method of manufacturing the ball-mounting mask in Embodiment 1 of the present invention will be described. First, a photosensitive film is attached to the stainless steel base material 6, and necessary exposure and development treatments are performed, and a photosensitive film layer 7 for forming convex portions is locally formed on the stainless steel base material 6 (see Fig. 5(a)). Moreover, although in the patent specification of the present invention, a negative-type photosensitive film is used, the photosensitive film used may also be a liquid photosensitive film. The photosensitive film layer 7 for forming the convex portion is, for example, in the shape of protrusions, lines, etc., but may be polygonal shapes, and is not limited to the shapes of protrusions and lines. Next, by electroplating the entire surface of the stainless steel base material 6 , for example, the primary plating layer 8 is formed so as to have a thickness of about 20 to 30 μm (see FIG. 5( b )). At this time, the formed primary plating layer 8 is divided into a primary residual plating portion 8a and a primary discarding plating portion 8b, and the primary residual plating portion 8a serves as a base (substrate) for separating and independent plural projections 5, and the primary discarding portion 8a is formed. The plated portion 8b is peeled off and removed in the next step. Then, after the formation of the primary plating layer 8 is completed, the photosensitive film layer 7 for forming the convex portion is removed (see FIG. 5( c )). Moreover, in this state, when viewed from above, the adjacent quadrangular opening pattern portions 3 are connected by connecting grooves 4 extending in the vertical vertical direction and the horizontal direction on the left and right at the center portion of each of the four sides of the upper, lower, left and right sides. , the quadrangular opening pattern portion 3 and the connecting groove 4 are connected to each other in a series, whereby the one-time electroplating layer 8 can be all at once, and only the base (substrate) of the plurality of separate convex portions 5 can be peeled off. Other than the primary residual plated portion 8a, which is peeled off and removed, the primary plated portion 8b is discarded (see FIG. 5( d )). Next, all the primary discarded plated portions 8b other than the primary residual plated portion 8a serving as the base (substrate) of the separate and independent plurality of convex portions 5 are removed, and only the plurality of separate and independent convex portions 5 remain on the stainless steel base material 6 The primary residual plating portion 8a of the base (substrate) is formed as an inner convex portion with a thickness of about 20 to 30 μm composed of the first plating layer (see FIG. 5( e )). In addition, although the illustration and detailed description are omitted, a known photosensitive film for forming openings is attached to the position where the square opening pattern portion 3 is formed on the stainless steel base material 6, and processing such as pattern exposure and development is performed. A photosensitive film for forming the openings 2 through which the conductive balls pass. Next, electroplating is performed on the stainless steel base material 6 and on the primary residual electroplating portion 8a serving as the base (substrate) of the separate and independent convex portions, so that the mask body has a predetermined thickness, for example, about 30 μm, thereby forming secondary electroplating Layer 9 (see Figure 5(f)). Thereby, the outer convex part which consists of the 2nd electroplating layer which covers the outer peripheral whole surface of the inner convex part is formed. Finally, from the stainless steel base material 6, the mask body including the primary residual plating portion 8a serving as the base (substrate) for separating and independent plural convex portions 5, and the quadrangle formed by the secondary plating layer 9 are peeled off. The opening pattern portion 3 and the plurality of independent convex portions 5 (refer to FIG. 5( g )) formed thicker than the connecting groove 4 (eg, thickness 50-60 μm). In this way, a ball mounting mask is completed, which includes a plurality of separate and independent protrusions 5 formed thicker than the quadrangular opening pattern 3 and the connecting groove 4 of the present invention. The quadrangular opening pattern part 3 in which the plurality of opening parts 2a through which the conductive balls penetrate is formed is a ball mounting area. Furthermore, the tip portion of the plurality of separate and independent convex portions 5 of the completed ball mounting cover 1 has an R-shape with roundness instead of an angular peripheral edge portion.

由二次電鍍層9之厚度（例如約30μm）所構成之連結凹槽4，雖然不必連結開口圖形部3的全部，但是，當考慮到來自紗網之張力，最大限度作用於開口圖形部3之效果，或於一次電鍍後，成為不需要之捨棄電鍍去除作業之工時時，最好即使僅至少上下(縱向)或左右(橫向)，或者，傾斜上下左右之任一方向，也以凹槽加工連結鄰接之全部之開口圖形部。 Although the connecting groove 4 formed by the thickness of the secondary plating layer 9 (for example, about 30 μm) does not necessarily connect all the opening pattern portion 3, it can act on the opening pattern portion 3 to the maximum extent considering the tension from the gauze. To achieve the effect, or when it becomes unnecessary to discard the man-hours of the plating removal operation after one plating, it is better to use the concave even if it is only at least up and down (vertical) or left and right (horizontal), or if it is inclined in either direction. The groove processing connects all the adjacent opening pattern parts.

在遮罩本體的圖形區域外周的非圖形區域，施做僅以二次電鍍層之厚度所形成之較薄之板厚部分，藉此，也可確認到形成有開口部之圖形區域內，作用更多水平方向之張力之效果，所以，即使在遮罩本體上的非圖形區域，故意形成僅以二次電鍍層所形成之膜厚般薄之部分，也沒關係。 In the non-pattern area of the outer periphery of the pattern area of the mask body, a relatively thin plate thickness formed only by the thickness of the secondary plating layer is applied, thereby, it can also be confirmed in the pattern area where the opening is formed. There is more effect of tension in the horizontal direction, so even if the non-pattern area on the mask body is deliberately formed as thin as the film thickness formed by the secondary plating layer, it does not matter.

為了防止附著助焊劑，在遮罩本體的被搭載物面側(內側)，係存在有形成複數圓柱或橢圓形之突起之導電性球搭載用遮罩，但是，遮罩用圖檔係需要配置這些複數突起到開口圖形周邊部之圖檔處理作業。導電性球搭載用遮罩的圖形，係一點一樣地存在有各種大小之圖形，所以，如專利文獻2所示，配置分離獨立之複數突起到遮罩用圖檔之作業係很煩雜。相對於此，本發明之導電性球搭載用遮罩，係凸部形成用之圖檔非常地單純且被簡化，所以，具有可大幅縮短花費於圖檔處理作業之作業時間之優點，在製作圖檔之面，也可期待謀求提高作業效率之效果。 In order to prevent the adhesion of flux, there is a mask for mounting conductive balls that forms a plurality of cylindrical or elliptical protrusions on the surface of the object to be mounted (inside) of the mask body. However, a mask file needs to be arranged The image processing operation of these plural protrusions to the peripheral portion of the opening pattern. The pattern of the mask for mounting a conductive ball has patterns of various sizes uniformly, so as shown in Patent Document 2, the operation system of arranging a plurality of separate and independent projections in the mask file is complicated. On the other hand, the mask for mounting a conductive ball of the present invention has the advantage that the drawing for forming the convex portion is very simple and simplified, and therefore, the work time for drawing the drawing can be greatly shortened. In terms of graphics, the effect of improving work efficiency can also be expected.

In this embodiment, the arrangement of the ball-mounting mask shows that there are 8 rows of rectangular opening pattern portions 3 in the vertical direction up and down, and 6 rows in the horizontal direction in the left and right directions, and a total of 48 are arranged. Furthermore, in the horizontal direction on the left and right, the adjacent square opening pattern portions 3 are connected by connecting grooves 4 extending in the horizontal direction on the left and right at the center portions of the left and right sides. In the horizontal direction of the left and right sides, the adjacent quadrangular opening pattern portion 3 and the connecting groove 4 are connected to each other in a series of cases. In the same manufacturing method as in Example 1, it is peeled and removed once. It has an important meaning in the peeling operation of electroplating (abandoning electroplating). The quadrangular opening pattern portion 3 and the connecting groove 4 are connected and formed by a secondary electroplating layer formed by a thinner plate thickness. Parts other than the quadrangular opening pattern portion 3 and the connecting groove 4 of the ball mounting mask 1 are formed as a plurality of separate and independent numbers (nine pieces) thicker than the quadrangular opening pattern portion 3 and the connecting groove 4. ) of the convex part 5. Thereby, the existence of the plurality of projections 5 separated and independent improves the strength as the ball mounting cover 1 . In this embodiment, the projections 5 extending in the horizontal direction by being separated and independent are shown, and nine rows are arranged at predetermined intervals in the up-down direction. Among the plurality of separate convex portions 5, the seven convex portions 5d disposed in the central portion extending in the horizontal direction are wider than the two disposed in the horizontal direction disposed at the upper end portion and the lower end portion. The convex portion 5e also has a narrow structure.

The lower side of the central portion of the portion 5e and the upper side of the central portion of the wider convex portion 5e at the lower end are respectively connected to the quadrangular opening pattern portion 3 and the connecting groove 4, and the lower or upper side of the central portion is serrated. Moreover, as shown in FIG. 7 and FIG. 8, the tip part of the 9 independent convex parts 5 is formed in the R shape which has the roundness of the peripheral edge part.

在上述實施例1中之球搭載用遮罩之製造方法中，係說明使彼此鄰接之四角形之開口圖形部3，與在上下左右之四邊之各中央部，於上下垂直方向及左右水平方向上延伸之連結凹槽4，彼此連結，僅一次全部剝離成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a以外的被剝離以去除之一次捨棄電鍍部分8b之情事。在本發明之實施例2中之球搭載用遮罩之製造方法中，於左右之水平方向上，彼此鄰接之四角形之開口圖形部3，係僅藉在左右之兩邊之各中央部，於左右之水平方向上延伸之連結凹槽4而連結，鄰接於上下之垂直方向等之開口圖形部3，係未藉連結凹槽4連結，但是，使僅以由與連結凹槽同等薄度所構成之二次電鍍層所形成之區域，設於遮罩本體的圖形區域外周部，以連結凹槽連接此圖形區域外周部與開口圖形部，與實施例1同樣地，即使係僅一個方向之連結，也可以一次全部剝離成為分離獨立之複數之凸部5的基礎（基底）之一次殘留電鍍部分8a以外的被剝離以去除之一次捨棄電鍍部分8b全部。又，與實施例2同樣地，例如即使僅以上下垂直方向之一個方向，彼此鄰接之開口圖形部被連結時，如果設置只有二次電鍍層之較薄板厚之區域，於遮罩本體的圖形區域外周部，以連結凹槽連接此圖形區域外周部與開口圖形部時，捨棄電鍍部分8b係可一次全部一起剝離。In the manufacturing method of the ball-mounting mask in the above-mentioned Embodiment 1, the rectangular opening pattern portion 3 adjacent to each other and the center portions of the four sides of the upper, lower, left and right sides in the vertical vertical direction and the horizontal direction of the left and right are described. The extending connecting grooves 4 are connected to each other, and the plated portions 8b other than the remaining plated portions 8a, which are the bases (substrates) of the separate and independent plural projections 5, are peeled off and removed once and are removed. In the manufacturing method of the mask for ball mounting in the second embodiment of the present invention, in the horizontal direction of the left and right, the square opening pattern portions 3 adjacent to each other are only borrowed from the center portions of the left and right sides to the left and right. The connecting grooves 4 extending in the horizontal direction are connected, and the opening pattern parts 3 adjacent to the vertical direction of the upper and lower directions are not connected by the connecting grooves 4, but are only made of the same thickness as the connecting grooves. The area formed by the secondary electroplating layer is set on the outer periphery of the pattern area of the mask body, and the outer periphery of the pattern area and the opening pattern portion are connected by connecting grooves.

Also, as in Example 2, when the adjacent opening pattern portions are connected even in only one of the vertical directions, for example, if a region with a relatively thin thickness of the secondary plating layer is provided, the pattern of the mask body will be reduced. When the outer peripheral portion of the region is connected with the opening pattern portion by the connecting groove, the plated portion 8b is discarded and can be peeled off all at once.
