[Technical Field] The main purpose of a "product design" is to have a high-strength sleeve, which can help it in addition to its shielding function. The body's structured circuit board is composed of fasteners to prevent the need. Can be a hex head length tongue design, its outer edge, the sleeve is placed in the front force yellow) buckle in the middle of the intersection and this cover is formed, moisture and moisture are also high-quality plastic Angled or open hollow 'can make the fastener cum tension spring and cover [new creation of the original creation, according to this creation' you can get a simple plastic cover with beautiful appearance, both can be obtained in this case. The characteristics of integrated circuits and appeals; and other components, in which the head can be lowered according to the type is a tension spring fastener with a contraction groove structure (together with the tension tension spring and the cover sleeve, the anti-conductive interference cover, The type of the head can be set. The port is a central opening with an embedded hole and a fastener. The heat sink of the circuit: the fastener with the buckle stress in this case; the same as the anti-interference guide point and the standard type required for assembly. State is mainly caused by: Among them, the fasteners include: fasteners, conductive high-quality plastics or round heads, etc. The inside of the inset tenon ends is the fastening portion; The interaction force can be made of multiple additional materials such as the cover of the fastener. The bottom of the cover groove of the round shape is divided by the plug-in tenon; the intersection produced by the suite Improved structure of the fastener After the structure is improved, due to the attached moisture-proof, moisture-proof and accurate and positioning fasteners and heat sinks made of the tension spring and cover specified in the case, the end handle is extended along the end of the end handle. Close the inner edge, and then fasten the entire fastener and make the fastener and cover to achieve the beautiful appearance can follow the handle of the fastener: In addition, the closed end is outside and in the middle as described above, through the interaction force, which is

M242984 V. Creation instructions (2) The fastener and the cover can be fastened to each other; when the fastener needs to fix the heat sink on the integrated circuit, it is only necessary to align the cover to the button hole and directly press down on the The fastener end handle in the cover can fasten the fastener on the circuit board at the fastest speed with reliable and good positioning, and complete the entire fastening procedure. In addition, in order that the fasteners therein have better fastening stress and the best elastic characteristics, the tenon ends of the fasteners can be designed in a three-tiered form, the first level is the fastening portion, and the second level Stop block (can enter the buckle hole of the circuit board to form a blocking function to prevent the buckle of the first layer from falling off due to excessive deformation due to excessive pulling stress), and the third layer is the connection portion ( Those who increase the stress of the second-level stop by a connection, and at the same time have the best elastic stress.) Those with a three-level structure. [Previous technology] Integrated circuit is an indispensable main component in the related electronics industry and information technology field; however, integrated circuit chips generate high heat during operation. The current solutions to achieve protection effects are A heat sink is applied to the surface of the integrated circuit chip to obtain rapid heat dissipation, which effectively prevents damage due to overheating. Check, Xi's integrated circuit chip (A 1), because it is quite expensive, and for convenience of testing, it is generally transferred through an adapter (commonly known as P || GA) (A 2) The integrated circuit chip (A 1) is directly plugged in; the opposite adapter (A 2) is fixed to the PC board (A 3) by soldering, as shown in the first figure; the heat dissipation of the learner The method is the same _ The heat dissipation is performed by a heat sink (A4) on the surface of the integrated circuit chip (A1), and between the integrated circuit chip (A1) and the heat sink (A4)

Page 6 350 M242984 Fifth, the creation description (3) is based on the most difficult to know: 1 · These transmissions, plus the softening caused by high heat, 2. There is no 3 laterally displaced wind tunnel fins. • Extending from the rear, it is necessary to closely cooperate with the heart to add wealth. Slowly, the assembly process is costly. 4 · The heat sink (A 4 ) May result in both elements. Based on the previous elimination; the design of the similar fasteners can still be stored in the structure, and then it will happen to be buckled; such a unified fastener is made of plastic, deformed and then issued a unified buckle The connector (1) is missing; it is applicable to the law. As mentioned in point 2, the method is the same; it is laborious to slide in the heat,

The conventional fasteners (A (A5) due to the low heat resistance of the tenon directly with the heat sink, will inevitably cause serious problems due to raw card release. A 5) is determined by the heat sink (A 4), so After fastening, the currently more advanced fasteners (A 5) with three-dimensional and multi-layered cummers will still be produced. Compared with the fastener assembly, it is necessary to use the "small piece of groove (A 4 1), so that The integrated circuit chip (A 1), which can not be said to be fast and reliable, is through PGA, compared with the additional or additional cooling fans and coolers on the integrated circuit (A 1) surface. In the meantime, non-human faults often occur due to poor plugging, etc. due to the lack of traditional fasteners. This fastener has gradually become the industry. The current fastener is shown in the second picture; The shortcomings and deficiencies in the implementation of the buckle (B 1), because it can not obtain better effects:

11IK

Page 7 951 M242984 V. Creation instructions (4) 1 · Since this type of fastener (B 1) is made of metal, although it is more heat resistant, it is insufficient for the stress of the fastener; once it occurs If the tensile stress is too large, the bifurcated fitting piece (B 2) may be opened and deformed, thereby losing the fastening function. 2 · Secondly, for this type of fastener, it is necessary to exert a great pressing force on the assembly to enable the buckle to be positioned, and the pressing force must be firmly fixed to the fastener (B 1 The top end (B 1 1) can only be implemented, so often at the moment when the force is pressed down, the problem of the implementation of deflection and wrong force is generated, which increases the difficulty of assembly. 3 · Because the learner ’s buckle has no shielding protection function, in addition to its appearance is rough and indecent, at the same time, the metallic buckle (B 1) and the tension spring (B 3) itself will lead to interference. problem. [New content] In response to the lack of traditional and learner ’s fasteners, this creation is to provide an “improved structure of integrated circuit heat sinks”, which not only conforms to the use of more advanced computer models, but also gives only “ "One press procedure", that is, the entire assembly process is completed, which virtually makes the entire integrated circuit assembly structure, as a result of this case, "better buckling stress, better positioning and the shielding function of the latest concept" can be obtained; At the same time, because of the cover structure added to the design in this case, in addition to combining the fastener and the tension spring into a "single-use component", it also solves the problem of scattered use of various parts of the user's fastener. ^: Shipping, calculation and use all have further added new value to achieve more perfect and perfect improvement.
