The reinforcing structure 114 includes a first rib 1141, a second rib 1142, and a third rib 1143. The first rib 1141 protrudes from the tongue 112, the second rib 1142 protrudes from the plate body 110 and is connected to the first end 1121 at the connecting end The ribs 1141 and the third ribs 1143 protrude from the plate body 110 and are connected to the second ribs 1142. The longitudinal direction D3 of the third ribs 1143 is different from the longitudinal direction D2 of the second ribs 1142.

In one embodiment, the plate 100 is, for example, an aluminum alloy plate. The plate 100 is made of a predetermined shape of the tongue 112 and the opening 111 by, for example, a cutter or a punch forming method. Before or after the tongue 112 and the opening 111 are formed in a predetermined shape, for example, the plate 110 and the tongue 112 are punched with a mold, and the reinforcing structure 114 is formed on the plate 110 and the tongue 112 in an integrated manner. In addition, the tongue piece 112 and the first rib 1141 protruding from the tongue piece 112 can also be bent on the board body 110 through bending, so that the board 100 can be combined with the electronic component by the reinforced tongue piece 112, or by using the reinforced tongue piece 112. The reinforced tongue piece 112 and the electronic component are locked by screws, thereby improving the support of the plate 100 to the electronic component, which can avoid the risk of the electronic component being collided and distorted due to insufficient strength of the plate 100 or the tongue piece 112.
