Embodiment Construction
[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0036] Such as figure 1 A method for using a bonding sheet shown, comprising the following steps:
[0037] S10. Provide a core board, and manufacture at least four copper discs on the core board.
[0038] In this embodiment, the provided core board is rectangular, and the copper discs are arranged on the diagonal of the core board and along the length directions of the four sides. Of course, in other embodiments, if the core board is rectangular, the copper disks can be separately arranged on the two diagonal lines of the core board or the copper disks can be separately arranged on the length directions of the four sides of the core board.
[0039] Specifically, copper discs are fabricated on the core board by etching. The number of core boards provided is multiple, and the specifications of each...
