Abstract
A PCB is fixed to a PCB stiffener to be held thereby, while an LSI is fixed to an LSI stiffener to be held thereby. The distal ends of four supporting bars provided in the LSI stiffener are screwed on the PCB stiffener, whereby the two stiffeners are firmly integrated with each other to be prevented from being warped. Since a heat sink can be mounted through tapped holes provided in the LSI stiffener, even if the PCB is a thin board such as a build-up substrate, it is possible to mount the heat sink without any difficulties.
Claims14
A mounting structure for an LSI, comprising:
- a first frame mounting and supporting a printed circuit board along a periphery of the printed circuit board, which carries said LSI;
- and
- a second frame supporting the printed circuit board surrounding the LSI and fixed to said first frame;
- wherein the printed circuit board is positioned between the first and second frames when the second frame is fixed to the first frame,
- wherein the second frame has a stiffener that supports the printed circuit board at least around the LSI when the second frame is fixed to the first frame.
A mounting structure in combination with an LSI device, comprising:
- a printed circuit board;
- a first frame supporting and mounting the printed circuit board along a periphery of the printed circuit board;
- an LSI device fixed to the printed circuit board with a solder;
- and
- a second frame mounted to the first frame, with the printed circuit board positioned between the first and second frames,
- wherein the second frame has a stiffener that supports the first frame at least around the LSI device.
