Description
Technical Field

Background
The centrifugal acceleration test of semiconductor electronic components is to fasten the electronic components on a rotating workpiece in a non-working state, and the centrifugal acceleration of the electronic components reaches tens to tens of thousands times of gravity acceleration along with the high-speed rotation of the workpiece and lasts for a certain time, and strong tensile stress is caused on each section of the electronic components under centrifugal acceleration, so that the adaptability of the electronic components under the action of the centrifugal acceleration is determined, and the firmness of the structure of the electronic components is assessed.
In order to ensure that the electronic components to be tested are firmly fixed on a workpiece rotating at a high speed, a layer of magnetic film is generally stuck to the inner cavity of the workpiece, and the magnetic film is formed by mixing magnetic powder and rubber according to a specific proportion and then pressing. Because the magnetic film works for a long time under the repeated impact of transverse and longitudinal shearing forces, the phenomena of cracking, aging and the like are very easy to occur, the service life is short, and the magnetic film needs to be replaced periodically.
At present, the magnetic film is completely replaced by a manual method. Firstly, after the magnetic film is cleaned, the adhesive is uniformly adhered on the surface of the magnetic film, and in order to avoid the influence of impurities such as dust and the like adhered on the surface of the adhesive on the viscosity of the adhesive, an adhesive protection film is adhered on the surface of the adhesive. Then tearing one end of the adhesive protection film, aligning one surface of the magnetic film with the adhesive with the inner cavity of the workpiece of the centrifugal machine, starting from one position, adhering the magnetic film while tearing the adhesive protection film, gradually pressing the magnetic film by hands after adhering, gradually expanding the magnetic film to the inner cavity of the whole workpiece, and gradually scraping the magnetic film from the center of the magnetic film to the periphery by using a scraping plate so as to expel bubbles below the magnetic film. Because the surface area of the inner cavity of the workpiece is large, the method can not ensure that bubbles between the magnetic film and the inner cavity wall of the workpiece are completely discharged, and the adhesion force of the magnetic film is uneven because the magnetic film is stressed and is negligibly small, so that the magnetic film is easy to peel and fall off in high-speed rotation of the workpiece.

Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 and 2 together, a method for adhering a magnetic film according to the present invention will now be described. The magnetic film pasting method is used for pasting the magnetic film 50 on the centrifuge workpiece 60 which can drive the electronic components to rotate at a high speed. The magnetic film 50 is a magnetic film 50 commonly used on the surface of a centrifuge workpiece 60 in the prior art, and is formed by mixing magnetic powder and rubber according to a specific ratio and pressing. The adhesive tape is adhered to the surface of the magnetic film 50, and the adhesive protective film 51 is adhered to the surface of the adhesive tape in order to prevent the adhesive tape from adhering impurities such as dust and the like to weaken the adhesive force.
The above-described magnetic film attaching method is for attaching a magnetic film to a workpiece using a magnetic film attaching tool including a holder 10, a first roller 20, a second roller 30, and a third roller 40.
The stand 10 has a space for accommodating the first, second and third rollers 20, 30 and 40. The first roller 20 is connected with the bracket 10, and is used for rolling the magnetic film 50 and guiding the magnetic film 50 to move, the length of the first roller 20 is larger than the width of the magnetic film 50, and a part of the magnetic film 50 which is not adhered is attached to the first roller 20, as shown in fig. 2. The second roller 30 is connected to the bracket 10 and located at one side of the traveling direction of the first roller 20, and has a diameter smaller than that of the first roller 20.

When the first roller 20 moves to the end of the magnetic film 50, the pushing pressing force is kept unchanged, then the uncovered adhesive protection film 51 is lifted and pulled at a constant speed to be separated from the magnetic film 50, meanwhile, the pushing support 10 moves in the opposite direction, the lifting action of the adhesive protection film 51 and the action of the pushing support 10 are simultaneously carried out, and thus, along with the gradual lifting of the adhesive protection film 51, the magnetic film 50 is gradually stuck on the inner wall of the workpiece 60 under the uniform pressure of the first roller 20.
The adhesive protection film 51 always contacts with the second roller 30 in a rolling manner in the lifting process and is always located below the second roller 30, the lifting angle of the adhesive protection film 51 by the second roller 30 is limited, and excessive adhesive is prevented from being exposed due to too fast or too much lifting of the adhesive protection film 51 (the more exposed parts of the adhesive are, the greater the probability of being contaminated with impurities such as dust is, the viscosity of the adhesive is reduced), so that the exposed parts of the adhesive are always flushed towards the workpiece 60 in the pasting process of the magnetic film 50, and the size is always fixed.
Because the magnetic film 50 is an elastic piece and can be bent at will, the incompletely-adhered magnetic film 50 passes through the bracket 10, is in rolling contact with the third roller 40 and is always positioned below the third roller 40, and the unbonded magnetic film 50 is limited by the third roller 40, so that the part of the magnetic film 50 to be adhered can be adhered to the first roller 20, and adhesion dislocation or adhesion inaccuracy caused by dislocation of the incompletely-adhered magnetic film 50 falling on the inner wall of the workpiece 60 is avoided.
Compared with the prior art, the magnetic film pasting method provided by the invention has the advantages that the whole pasting process of the magnetic film 60 is formed by rolling once, the stress of the magnetic film 60 is uniform, and the magnetic film 50 and the inside of the workpiece 60 can be ensured not to remain air bubbles. Has the characteristics of simple structure, convenient use and high pasting efficiency.
In order to stabilize the structure of the bracket 10, as a specific embodiment of the magnetic film attaching method provided by the present invention, the bracket 10 includes a first fixing rod 11 and a supporting rod 14. The first roller 20 is sleeved on the first fixing rod 11.
