The groove 14 can be rectangular and is located at a center of the first plate 10. The first plate 10 has an axis L which is coincident with an axis of the groove 14 and the first through hole 12. Specifically, the groove 14 is penetrates through a center of the first slot 11 to divide the first slot 11 into a first zone A and a second zone B. The first slot 11 is symmetrical about the groove 14.
In the illustrated embodiment, the groove 14, the first slot 11, the first through hole 12 and the first connection holes 13 can be defined by die cutting machine. A depth of the first slot 11, the first through hole 12, the first connection holes 13 and the groove 14 are equal to a thickness of the first plate 10. The first slot 11 includes a series of rounding gaps spaced from each other. The rounding gaps each surround an adjacent gap one after another. Specifically, the first slot 11 includes a first gap 111, a second gap 112, a third gap 113, a fourth gap 114, a fifth gap 115, a sixth gap 116, a seventh gap 117, a eighth gap 118 and a ninth gap 119 arranged from inside to outside. Further, the first gap 111, the second gap 112 and the third gap 113 together form a first group 120. A perimeter size of the first gap 111 is larger than a size of the second gap 112, and the perimeter size of the second gap 112 is larger than a perimeter size of the third gap 113. Perimeter sizes of the rounding gaps are arranged in that manner. The fourth gap 114, the fifth gap 115 and the sixth gap 116 together form a second group 130. The seventh gap 117, the eighth gap 118, and the ninth gap 119 together form a third group 140. A distance between the first group 120 and the second group 130 is equal to a distance between the second group 130 and the third group 140. In each group, a distance between the two adjacent gaps is the same, and is less than the distance between two adjacent groups. Each gap communicates with the groove 14 and is symmetrical about the groove 14.
The first through hole 12 is configured at an outer end of the first slot 11. The first connection holes 13 is configured between the first slot 11 and the first through hole 12. An end of the ninth gap 119 close to the first through hole 12 extends through the first connection hole 13 to communicate with the first through hole 12. The first connection hole 13 is configured for coupling to a circuit.

The second slot 21, the second through hole 22 and the second connection hole 23 can be defined by die cutting machine. A depth of the second slot 21, the second through hole 22 and the second connection holes 23 is equal to a thickness of the second plate 20. The second slot 21 is a continuous rounding gap. While the second plate 20 is fixed with the first plate 10, the second slot 21 overlaps with the gaps of the first slot 11 in serious from inside to outside continuously, and connects two adjacent gaps of the first slot 11 at the groove 14 of the first plate 10. The second through hole 22 is configured at an outer end of the second slot 21 and is located corresponding to the first through hole 12. There are four second connection holes 23. Two of the second connection holes 23 also named as outer connection holes 231 are corresponding to the first connection holes 13 and are located between the second slot 21 and the second through hole 22. The other two of connection holes 23, also named as inner connection holes 232, spaced from each other are surrounded by the second slot 21 and connect with a inner end of the second slot 21. The second slot 21 begins from one of the inner connection holes 232 and an ourter end of the second slot 21 extends through one of the outer connection hole 231 to communicate with the second through hole 22.
At block 105, referring to
While the first plate 10 is fixed with the second plate 20 together, the second through hole 22 overlaps with the first through hole 12, the second connection hole 23 overlaps with the first connection hole 13. The second slot 21 overlaps with the gaps of the first slot 11 from inside to outside. Specifically, at the first zone A, the second slot 21 overlaps the second gap 112, the fourth lap 114, the sixth lap 116, the eighth lap 118 of the first slot 11; at the second zone B, the second slot 21 overlaps the first gap 111, the third gap 113, the fifth gap 115, the seventh gap 117 and the ninth gap 119 of the first slot 11.
At block 106, removing the single-side adhesive from the first plate 10.

A size of the third through hole 31 is larger than that of the first through hole 12 of the first plate 10. The four third connection hole 32 are spaced from each other, including two upper connection holes 321 and two lower connection holes 322. The two upper connection holes 321 are located between the two lower connection holes 322 and the third through hole 31. The upper connection holes 321 are also corresponding to both the first connection holes 13 and the outer connection holes 231. The lower connection holes 322 are corresponding to the inner connection holes 232.
