Description

PROTECTIVE FOR AGAINST DAMAGING CIRCUIT BOARD AND FOR SAFEGUARDING CHIP}

The present invention relates to a protective shield (Shield) for preventing damage to the circuit board and the chip, more specifically, to cover the top of the chip with a metal shield, the chip scratches during assembly and disassembly of the heat dissipation device provided on the top of the chip To prevent excessive damage, and to conduct and release the heat energy generated by the heat sink and the fan mounted on the top of the chip.

In general, advanced circuit boards with faster algorithm speeds need to be equipped with more advanced (with faster algorithm speeds) chips. Especially for high-quality three-dimensional animation images, a better color display device requires a VGA (Video Graphic Array) card and a high-performance computer motherboard. However, chips of the same resolution and algorithm speed are very expensive and generate heat during processing. Therefore, the chip is required to be provided with a heat sink, a fan, and a fitting device for fitting the heat sink on the chip, but the fitting device for fitting the fan and the heat sink is determined to be a consumable. Consumables used on more expensive circuit boards should be replaced periodically with new ones. However, due to the limitation and negligence of the work space during assembly and disassembly of the heat sink, the tips and edges of the metal fittings or the heat sink may easily scratch the surface of the chip and cause permanent damage to the chip. Thus, expensive circuit boards can frequently fail or be seriously damaged. It is very important that the difficulty of disassembling or assembling various consumables on expensive circuit boards with limited working space, and how the shortcomings of scratches and damage can be overcome by sharp metal parts as described above .

Accordingly, an object of the present invention is to provide a metal shield that can cover the entire upper portion of a chip on a circuit board in order to overcome the above-mentioned conventional problems.

The metal shield according to the present invention includes a plane in which five surfaces are shielded and a lower opening surface, and the bottom surface of the upper surface of the metal shield is formed to be in contact with the upper surface of the chip, thereby preventing heat energy generated by the chip. Conduct and release. The metal shield additionally has a heat sink and a fan. By using the above-described structure, the metal shield can be protected from scratches and damage by the sharp edges of the metal, and can reduce the damage caused by humans and extend the life of the chip.

Hereinafter, in order to be described in detail so that those skilled in the art can easily implement the present invention, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. . Other objects, features, and operational advantages, including the object, operation, and effect of the present invention, will become more apparent from the description of the preferred embodiment.

Referring to Figures 1 and 3A, the present invention relates to a particular improved algorithm chip 20 (e.g. a CPU chip provided on a VGA card or a mother board) installed on a circuit board 10. A flange having at least two pairs of insertion openings 11 and 12 mounted in the at least two pairs, and a flange having at least two fasteners on a side surface formed around a shielded plane, a lower opening surface, and a metal shield. The sidewalls formed around the shield extend slightly outwardly, and the outwardly extending angle of the sidewalls is vertically about 30 °.

As can be seen in the attached Figures 1, 2 and 3a, the metal shield 30 covers the entire chip and the bottom surface of the top surface of the metal shield 30 is in contact with the top surface of the chip. In addition, the contact plane between the metal shield 30 and the chip 20 has a layer of thermally conductive adhesive 60 to distribute heat energy generated by the chip, such as the metal shield 30 for heat dissipation. . On top of the metal shield 30, a heat sink 40 and a fan 70 are additionally provided for better heat dissipation effect. In addition, the heat shield 40 is mounted on the circuit board 10 so that the metal shield 30 is sandwiched and fixed between the circuit board and the heat sink. In addition, a layer of thermally conductive adhesive 61 is applied between the metal shield 30 and the heat sink 40.

In a specific embodiment of the present invention, the heat sink 40 and the circuit board 10 is fixed by the method described below. Two side surfaces corresponding to the heat sink 40 are provided as the fixing piece 41. Each of the two fixing nails 50 is inserted through the fixing piece 41 and fixed through the insertion opening 12 of the circuit board 10, at which time the metal shield 30 is inserted and fixed at the same time. The fan 70 will be mounted on the heat sink 40 for better heat dissipation effect.

1, 2 and 3b, the metal shield 30 is independently fixed on the circuit board 10. As shown in FIG. The flange 31 having the fastener 32 coincides with the other insertion opening 11 and is inserted through the two fixing nails 51 so that the metal shield 30 is directly fixed to the circuit board 10. . 2 and 4, when the metal shield 30 and the heat sink 40 are individually fixed to the circuit board, the fixing piece 41 of the flange 31 and the heat sink 40 of the metal shield 30 are fixed. It is shown that they are staggered and can be fixed more easily.
