Further, the first reinforcing member 5 has a plate shape.
Each of the openings 53 penetrates the first reinforcing member 5.
Further, the second reinforcing member 4 has a plate shape.
Further, the solder resist layer 26A can be formed by applying a thermosettingsolder resist to the top surface of the first reinforcing member 5A, for example.
Thereby, the rigidity of the reinforcing member 5B is improved.
The reinforcing member 300 is used to reinforce the body portion 5A' and is relatively rigid.
To increase durability, attach reinforcing members to the girder.
The first reinforcing member 5A is a flat plate having a flat front and back surface, and an opening portion is not formed.
Moreover, the heat dissipation property of the first reinforcing member 5 can also be improved.
The second reinforcing member 4A is a flat plate having a flat front and back surface, and an opening portion is not formed.
According to this procedure, the first reinforcing member 5A can be efficiently etched.
The first reinforcing member 5A is a first reinforcing member 5 and is made of, for example, a metal material.
As a Fe-Ni system Thealloy can be the same as the second reinforcing member 4 described above.
The second reinforcing member 4A is the second reinforcing member 4 and is made of, for example, a metal material.
The solder resist layer 26 can be formed of the same material as the solder resist layer 25,and can be formed in the reinforcing member 5A described later in the same manner.
Thereby, contact between the first reinforcing member 5 and each of the metal bumps 71 can be prevented.
Thereby, the metal bumps 71 are reinforced by the insulating material 81,and the contact between the metal bumps 71 and the reinforcing members is prevented by the insulating material 81.
When the second reinforcing member 4 is made of a metal material, the thermal conductivity of the second reinforcing member 4 can be improved.
Further, in the above-described embodiment,the method of manufacturing each layer from the side of the reinforcing member 5A is used, but a method of manufacturing each layer from the side of the reinforcing member 4A may be employed.
When the first reinforcing member 5 is made of a metal material, the heat dissipation property of the first reinforcing member 5 can be improved.
At this time,in the step of forming the opening portion 41 on the reinforcing member 4A, the opening portion 41 may be formed while thinning the reinforcing member 4A.
The reinforcing members inoptical cable can be metal reinforcing members of high strength stainless steel wire or phosphating steel wire, or non-metal reinforcing members of polyester aramid filament or other suitable fiber bundles.
Moreover, by appropriately selecting the constituent materials of the first reinforcing member 5 and the second reinforcing member 4, the heat dissipation property of the semiconductor package 1 can be improved.
Thereby, the first reinforcing member 5 effectively reinforces the wiring board 2, and thermal expansion of the entire semiconductor package 1 can be suppressed.
Thereby, the semiconductor element 3 and the second reinforcing member 4 integrally reinforce the wiring board 2, and thermal expansion of the entire semiconductor package 1 can be suppressed.
At this time, the reinforcing member 4A serves as the first reinforcing member, and the reinforcing member 5A serves as the second reinforcing member.
The thickness of the first reinforcing member 5A is not particularly limited, but is preferably about 1 mm to 5 mm thicker than the thickness of the first reinforcing member 5.
In addition, the average thickness of the second reinforcing member 4 is determined in accordance with the thermal expansion coefficient of the wiring board 2, the shape, the size, and the constituent material of the wiring board 2, and is not particularly limited, and is, for example, about 0.02 mm or more and 0.8 mm or less.
Membrane structure form: It is a kind of space structure form that many kinds of high-strength film materials(PVC orTeflon) and reinforced members(steel frame, steel column or steel cable) produce certain prestressing stress in order to form a certain spatial shape, as a covering structure, and can withstand certain external loads.
