Technical Field

[0001] This application belongs to the field of computer motherboard adhesive manufacturing technology, specifically a multi-functional adhesive for computer motherboards. Background Technology

[0002] Computer motherboards contain numerous circuits, so multi-functional adhesive strips are used to attach them, providing functions such as conductivity, shielding, flame retardancy, and adhesion. Currently, each type of adhesive strip is separate, making it inconvenient to use. Utility Model Content

This saves assembly time and improves assembly accuracy during use.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] A multi-functional adhesive for computer motherboards includes a PET silicone protective film, a main release film, a first conductive copper foil double-sided adhesive, and a secondary release film. The main release film is attached to the back of the PET silicone protective film, and the PET silicone protective film has positioning holes. The first conductive copper foil double-sided adhesive has protruding portions on its left and upper edges. The first conductive copper foil double-sided adhesive is located on the upper left part of the front side of the PET silicone protective film, and the second conductive copper foil double-sided adhesive is located on the lower right part of the front side of the PET silicone protective film. The front side of the PET silicone protective film has ordinary double-sided adhesive and a secondary release film covering the protruding portions.

[0006] Preferably, the lower right portion of the first conductive copper foil double-sided adhesive overlaps the second conductive copper foil double-sided adhesive.

[0007] Preferably, the front side of the PET silicone protective film is provided with several pieces of ordinary double-sided adhesive.

[0008] Preferably, there are three first conductive copper foil double-sided adhesive tapes, which are overlapped and attached to the front side of the PET silicone protective film.

[0009] Preferably, each piece of the ordinary double-sided tape has the same thickness.

[0010] Preferably, the surface impedance of the first conductive copper foil double-sided adhesive is ≤50mΩ and the vertical impedance is ≤50mΩ.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] The application proposes a multi-functional adhesive for computer motherboards, which integrates a first conductive copper foil double-sided adhesive, a second conductive copper foil double-sided adhesive, and ordinary double-sided adhesive onto a PET silicone protective film. This design saves assembly time and improves assembly accuracy during use. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the structure assembled according to this application.

[0015] The components include: 1. PET silicone protective film; 2. main release film; 3. first conductive copper foil double-sided adhesive; 4. secondary release film; 5. protruding part; 6. second conductive copper foil double-sided adhesive; 7. ordinary double-sided adhesive; and 8. positioning hole. Detailed Implementation

[0016] Reference Figures 1-2 A multi-functional adhesive for computer motherboards includes a PET silicone protective film 1, a main release film 2, a first conductive copper foil double-sided adhesive 3, and a secondary release film 4. The main release film 2 is attached to the back of the PET silicone protective film 1. The PET silicone protective film 1 has positioning holes 8. The first conductive copper foil double-sided adhesive 3 has protruding portions 5 on its left and upper edges. The first conductive copper foil double-sided adhesive 3 is located on the upper left part of the front side of the PET silicone protective film 1. The second conductive copper foil double-sided adhesive 6 is located on the lower right part of the front side of the PET silicone protective film 1. The front side of the PET silicone protective film 1 has ordinary double-sided adhesive 7 and a secondary release film 4 covering the protruding portions 5.

[0017] In this embodiment, the PET silicone protective film 1 is a silicone protective film with stable adhesion, which will not damage the surface of the first conductive copper foil double-sided adhesive 3 when the protective film is removed; the main release film 2 is a release film with low release force, which is conducive to easy removal after assembly; the first conductive copper foil double-sided adhesive 3 is made of PC, which has good insulation and flame retardant properties, and the flame retardant rating reaches VTM-0; the second conductive copper foil double-sided adhesive 6 is a low-resistance, high-adhesion conductive copper foil double-sided adhesive, which has better conductivity, shielding and adhesion, and the three layers of copper foil can improve heat dissipation performance; the ordinary double-sided adhesive 7 is a double-sided adhesive with strong adhesion of the same thickness, which makes the adhesion to the component more firm; these 5 adhesives are processed by dispensing, which can save materials and reduce costs; the secondary release film 4 is a double-sided release film, which plays a foolproof role and prevents operators from applying the release side backwards during assembly, causing product scrapping;

[0018] When using the product, remove it from the main release film 2, then remove the secondary release film 4, and bend and attach it along the dotted line of the PET silicone protective film 1. Finally, remove the PET silicone protective film 1, taking the main release film 2 with it. Products of different materials and shapes can be fixed to the PET silicone protective film 1, allowing customers to assemble them in one go, greatly saving assembly time and improving assembly accuracy.

[0019] As a preferred embodiment, the lower right portion of the first conductive copper foil double-sided adhesive 3 overlaps the second conductive copper foil double-sided adhesive 6. This makes the assembly more stable.

[0020] As a preferred embodiment, the front side of the PET silicone protective film 1 is provided with several pieces of ordinary double-sided adhesive 7. The ordinary double-sided adhesive 7 is selected from double-sided adhesives of the same thickness with relatively strong adhesion, so that the adhesion to the substrate is more secure.

[0021] As a preferred embodiment, there are three first conductive copper foil double-sided adhesive strips 3, which are overlapped and attached to the front side of the PET silicone protective film 1. The three layers of copper foil stacking can improve heat dissipation performance.

[0022] As a preferred method, each piece of the ordinary double-sided tape 7 has the same thickness. Using ordinary double-sided tape 7 of equal thickness with relatively strong adhesion makes the adhesion to the object more secure.

[0023] As a preferred embodiment, the surface resistance of the first conductive copper foil double-sided adhesive 3 is ≤50mΩ, and the vertical resistance is ≤50mΩ;

[0024] As a preferred embodiment, the tack of the ordinary double-sided adhesive is >0.725 N / mm.
