s1: preprocessing, installing a memory bank 3 packaged with a memory chip into a memory slot 2 of a mainboard 1 to obtain a hardware unit;
s2: the contact protection is carried out, wherein an insulating waterproof adhesive tape is adopted to cover the seam between the memory strip 3 and the memory slot 2 of the hardware unit in the S1, so as to form a contact sealing tape 6;
s3: surface protection, namely coating the outer surface of the memory bank 3 and the edge of the contact seal tape 6 on the surface of the memory bank 3 by using pouring sealant to form a surface sealing part 7;
s4: and bottom seam protection, namely coating the connecting position of the memory slot 2 and the mainboard 1 and the edge of the contact sealing tape 6 on the surface of the memory slot 2 by using pouring sealant to form a bottom sealing part 8.
Further, step S1 includes:
s11: packaging protection, namely coating the memory strip 3 packaged with the memory chip 4 with a tearable shielding adhesive, and curing the memory strip to obtain an integrated memory strip 3;
s12: encapsulating and protecting, namely encapsulating a gap between the memory chip 4 in the integrated memory strip 3 and the memory strip 3 by using an encapsulating adhesive to ensure that the atmospheric pressure in the gap is smaller than the outside atmospheric pressure to form an encapsulating part;
s13: assembling the memory slot 2 and the mainboard 1, removing the tearable masking glue on the surface of the integrated memory strip 3, and installing the integrated memory strip 3 into the memory slot 2 to obtain a hardware unit.
The method comprises the assembly and protection of a hardware structure, because most of the purchased integrated memory banks are packaged with memory chips, the assembly part is that the memory banks 3 are correspondingly installed with the mainboard 1 through the memory slots 2, and the protection of the structure is divided into two parts, one part is the protection of the structure between the memory chips 4 and the memory banks 3, and the other part is the protection of the structure between the memory banks 3 and the mainboard 1.
Therefore, step S11 of step S1 is performed to remove the sticker and the label on the integrated memory bank and remove the auxiliary heat sink or the heat dissipation vest disposed on the memory bank 3. And then coating the memory strip 3 packaged with the memory chip 4 with a tearable shielding adhesive, specifically coating the contact part (golden finger 5) of the memory strip 3 and the bayonet parts at two ends of the memory strip 3 with the tearable shielding adhesive so as to prevent the contamination of a protective material from influencing the normal use of the product. The adopted tearable masking adhesive should satisfy the condition of no residue peeling and need to maintain the working performance under a certain heating condition. Specifically, the temperature resistance of the tearable shielding adhesive can meet the requirement of one hour of exposure at 120 ℃, and the tearable shielding adhesive is a material which is universal in the industry and can be directly obtained by purchase.
Then, step S12 is performed, a potting adhesive is used to pot and seal the gap between the memory chip 4 and the memory bar 3 in the integrated memory bar 3, so that the atmospheric pressure in the gap is smaller than the outside atmospheric pressure, and a potting part is formed; specifically, the gap can be filled and sealed in a heating state, so that the gap is in a negative pressure state, and meanwhile, the solidification of the filling and sealing part is facilitated, wherein the heating temperature is the upper limit temperature of the hardware unit in a working state at room temperature, for example, the filling is carried out in an environment of 80 ℃.
And step S13, removing the tearable masking tape, assembling the integrated memory stripe 3, the memory slot 2 and the motherboard 1 together, checking that the connection is good and the memory works normally, and completing step S1.
In step S1, the packaging, protection, and hardware unit assembly between the memory chip 4 and the memory bank 3 are completed, and then steps S2, S3, and S4 are performed in sequence.
In step S2, the insulating and waterproof tape is mainly silicone or other functional tape, and besides insulating and waterproof, the tape is flexible, has no adhesive residue when peeled off, and has a certain heat dissipation property. When the memory strip is pasted, the lower edge of the insulating waterproof adhesive tape extends along the surface of the memory slot 2 to cover the position close to the mainboard 1, the upper edge is tightly attached to the surface of the memory strip 3, and meanwhile, in order to enable the insulating waterproof adhesive tape to be tightly attached to the bonding surface at the corner as far as possible, the adopted insulating waterproof adhesive tape also has the characteristic of thin thickness. Preferably, the glass fiber substrate blue film white organic silicon double-sided heat conduction adhesive tape with the width of 8-10mm and the thickness of 0.2-0.5mm is selected in practical operation.
In step S3, coating the outer surface of the memory bank 3 and the edge of the contact sealing tape 6 on the surface of the memory bank 3 with a potting adhesive to form a surface sealing portion 7; the pouring sealant not only covers the gap between the contact sealing tape 6 and the memory bar 3, but also covers other components welded on the surface of the memory bar 3 and exposed except the memory chip 4. Besides the insulating, waterproof and heat-conducting properties, the adopted pouring sealant is not too hard after being cured, so that the pouring sealant can be conveniently removed when the memory needs to be repaired or replaced. In addition, in order to prevent the glue solution from permeating into the golden finger 5 to contaminate the contact due to capillary action, the viscosity of the used potting glue is more than 1000mPa.s (empirical reference value, upper limit of viscosity of three-proofing paint). Preferably, the engineering chooses the RTVS189 two-component silicone resin pouring sealant, which is the cured RTVS189(A/B) silicone elastomer, which is supplied as a two-component suit material and consists of A, B two-component liquid components, wherein when the two components are mixed by 1: when the weight ratio or the volume ratio of 1 is fully mixed, the mixed liquid can be solidified into a flexible elastomer.
In step S4, a potting adhesive is used to cover the lower edge of the contact tape and the gap between the memory slot 2 and the paper board, so as to form a bottom sealing portion 8 structure. And finally, covering other gaps on the peripheries of the buckles at the two ends of the memory slot 2 by using insulating waterproof heat-conducting silica gel to form a peripheral sealing part 10 structure. The performance requirements of the bottom sealing part 8 and the peripheral sealing part 10 are the same as those of the surface sealing part 7, and RTVS189 two-component silicone resin pouring sealant is selected in engineering. And the golden finger 5 part of the memory bank 3 and the contact part of the memory slot 2 are completely isolated from the outside in an airtight way, and the protection process is finished.
The protection process completely and airtightly isolates the memory bank of the desktop computer and the electronic circuit part of the memory slot thereof from the outside, and simultaneously does not influence the heat dissipation of each electronic component. Through tests, the hardware unit treated by the protection process can normally work in a water vapor supersaturation environment with the relative humidity of 100% and liquid dewing in the air. Meanwhile, the protective materials selected in the processing technology of the hardware unit protective structure can be removed, and the protective components are not damaged in the processes of removing the protective process and implementing the protective process, so that the product repair is not influenced. Meanwhile, the process has no special structural requirements on the protected components, is suitable for various existing commercially available memory products, and is also suitable for small-batch customized processing.
