Description

Technical Field

[0001] This application relates to the field of glass substrate technology, and in particular to a glass substrate with positioning holes. Background Technology

[0002] When performing ball-mounting processes on existing glass substrates, since there is no positioning design on them, an additional carrier with positioning holes must be set up. The glass substrate is placed on this carrier so that the ball-mounting machine can be positioned to perform the ball-mounting operation. After the ball-mounting operation is completed, the carrier must be removed for subsequent processes.

[0003] Please refer to Figure 1 The diagram illustrates the steps of a current ball-mounting process on a glass substrate. First, the glass substrate is placed on a carrier with positioning holes (step S110), and then a ball-mounting machine positions it for ball placement (step S120). Next, a reflow soldering operation is performed to secure the solder balls to the glass substrate (step S130). Then, residual flux on the glass substrate is cleaned (step S140). Next, a receiving operation is performed (step S150), and finally, the glass substrate is separated from the carrier (step S160). Utility Model Content

[0004] Based on this, this application proposes a glass substrate with positioning holes, which allows the ball-planting machine to directly perform ball-planting operations on the glass substrate.

[0005] To achieve the above objectives, the glass substrate of this application is a rectangular substrate with two long sides and two short sides. The two long sides are of the same length, and the two short sides are of the same length. The length of the two long sides is greater than the length of the two short sides. The two long sides are respectively a first long side and a second long side, and the two short sides are respectively a first short side and a second short side. A center line is defined by connecting the centers of the first long side and the second long side. The glass substrate is characterized in that: two circular first positioning holes are provided on the glass substrate, respectively located on both sides of the center line. The distance from the center point of the two first positioning holes to the first long side is greater than 1.0 mm and less than the distance to the second long side.

[0006] Based on the glass substrate with positioning holes of this invention, there is no need to set up an additional carrier with positioning holes. In subsequent drilling, printing, ball placement and molding operations can be performed directly on the glass substrate, saving the step of carrier conversion and increasing the accuracy of positioning.

[0012] The following disclosure provides numerous different embodiments or instances for implementing various features of this disclosure. Specific examples of components and configurations are described below to simplify this disclosure. Of course, these components and configurations are merely examples and are not intended to be limiting. For example, in the following description, the formation of a first member on or above a second member may include embodiments where the first member and the second member are formed in direct contact, and may also include embodiments where additional members may be formed between the first member and the second member such that the first member and the second member are not in direct contact. Furthermore, reference numerals and / or letters may be repeated in various instances of this disclosure. This repetition is for simplicity and clarity and does not in itself indicate a relationship between the various embodiments and / or configurations discussed.

[0013] In addition, for ease of description, spatial relative terms such as “under,” “below,” “lower,” “overlapping,” “upper,” and similar terms may be used herein to describe the relationship between one component or member and one or more components or members as illustrated in the figures. Besides the orientations depicted in the figures, the spatial relative terms are intended to cover different orientations of the device in use or operation. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein shall be interpreted accordingly.

[0014] Please refer to Figure 2The glass substrate 100 with positioning holes in this invention is a rectangular substrate that has been sealed with adhesive and then debonded to separate the additional circuit board (glass). It has two long sides and two short sides, wherein the two short sides are parallel and perpendicularly connected to the two long sides. In this invention, the two long sides are a first long side 111 and a second long side 112; the two short sides are a first short side 113 and a second short side 114. The first long side 111 and the second long side 112 have the same length; the first short side 113 and the second short side 114 have the same length. A center line 110 is defined by connecting the centers of the two long sides, and it is parallel to the two short sides. Therefore, the length of the glass substrate 100 is the length of either the first long side 111 or the second long side 112, and the width of the glass substrate 100 is the length of either the first short side 113 or the second short side 114, and the length of the glass substrate 100 is greater than its width.

[0015] After debonding, the glass substrate of a fan-out flip-chip size-scale package (FOFCCSP) has dimensions of 155mm × 85mm. Therefore, the glass substrate 100 with positioning holes according to this invention can have a length of 155mm and a width of 85mm, but this invention is not limited to these dimensions; other sizes of glass substrates are also possible. For example, the size of the glass substrate 100 of this invention can also be less than 800mm × 800mm.

[0016] The glass substrate 100 with positioning holes according to this invention includes two first positioning holes 121 and two second positioning holes 122. The two first positioning holes 121 and the two second positioning holes 122 are circular holes with an equal diameter greater than 1.0 mm.

[0017] The distance from the center point of the two first positioning holes 121 to the first long side 111 is greater than 1.0 mm and less than the distance to the second long side 112; the distance between the center points of the two first positioning holes 121 is greater than 1 / 2 the length of the first long side 111; the distance from the center point of the two first positioning holes 121 to the center line 110 is greater than 1 / 4 the length of the first long side 111.

[0018] The distance from the center point of the two second positioning holes 122 to the second long side 112 is greater than 1.0 mm and less than the distance to the first long side 111; the distance between the center points of the two second positioning holes 122 is greater than 1 / 2 the length of the second long side 112; the distance from the center point of the two second positioning holes 122 to the center line 110 is greater than 1 / 4 the length of the second long side 112.

[0019] According to the glass substrate 100 with positioning holes of this invention, its positioning design requires more than two positions for positioning, and the additional positioning position can increase the identification direction and position. Therefore, the glass substrate 100 with positioning holes of this invention can be provided with only two first positioning holes 121 or two second positioning holes 122.

[0020] Based on the glass substrate with positioning holes of this invention, there is no need to set up an additional carrier with positioning holes. In subsequent drilling, printing, ball placement and molding operations can be performed directly on the glass substrate, saving the step of carrier conversion and increasing the accuracy of positioning.

[0021] Although the foregoing examples have illustrated this invention, they are not intended to limit it. Anyone with ordinary knowledge in the technical field to which this invention pertains may make various alterations and modifications without departing from the spirit and scope of this invention. Therefore, the scope of protection of this invention shall be determined by the appended claims.
