The wire 50 connects the first pad 20 and the second pad 21. The wire 50 includes at least a first connection section 51, a second connection section 53, and a first bending portion 52, the first connection section 51 is connected to the first bonding pad 20, the second connection section 53 is connected to the second bonding pad 21, and the first bending portion 52 is connected to the first connection section 51 and the second connection section 53.

It can be appreciated that, in the present embodiment, the wire 50 is bent back and forth from the first pad 20 to the second pad 21, which can effectively reduce the risk of wire breakage of the wire 50. The insulator 60 covers the frame area NA, and the insulator 60 encapsulates the wire 50, the first pad 20 and the second pad 21, so that the wire 50 can be effectively isolated from the outside air, and the wire 50 is prevented from being oxidized.
Alternatively, the insulator 60 may be formed by thermal curing or photo-curing.
Optionally, in this embodiment, a first electrical conductor 51a is further disposed at a connection portion between the first connection section 51 and the first bonding pad 20, and the first electrical conductor 51a is connected to the first bonding pad 20 and the first connection section 51; the connection between the second connection section 53 and the second bonding pad 21 is further provided with a second conductive body 53a, and the second conductive body 53a is connected to the second bonding pad 21 and the second connection section 53.

In the present embodiment, the wire 50 may be fixed to the first pad 20, the second pad 21, and the first insulator 61 by thermally curing or photo-curing the insulator 60. In some products that can withstand high temperatures, the materials of the first conductor 51a and the second conductor 53a may be selected from solder paste. The wires 50 are then filled by means of ink jet, printing, aerosol or dispensing, further securing the wires 50.
