Abstract
Disclosed is a heat-conductive elastic protection member for a harper, which is not stretched even when used repeatedly, can maintain a close contact force with an object, and is not easily worn even when in direct contact with the harper. The protective member includes a metal foil and an elastic heat-conductive elastic sheet laminated on one surface of the metal foil, and is continuously supplied in a roll-to-roll manner so that the metal foil is in direct contact with the haba machine.
Description
Technical Field
The present invention relates to a heat conductive elastic protection member, and more particularly, to a heat conductive elastic protection member having excellent heat conductivity, which is not easily stretched by heat even when repeatedly used in a harp machine, can maintain an elastic contact force with an object, and is not easily worn even when directly contacted with the harp machine.
Background
A pair of opposing objects, such as an LCD panel of a touch panel or the like and an FPCB on which a sensor IC is mounted, are adhesively bonded to each other by heat and pressure using an Anisotropic Conductive Film (ACF), so that each sensor electrode of the panel is electrically connected to each sensor pin of the sensor IC.
The anisotropic conductive film is one of conductive films in which metal powder and thermosetting resin that is cured by heat are mixed, and it is necessary to apply predetermined temperature, pressure, and time due to its characteristics, and for this purpose, it is possible to perform thermal welding by pressing the surface of an object using a haba machine (hot bar) equipped with a heater for supplying heat.
For example, in the case of heat welding, the temperature and the pressing time of the haba machine vary depending on the object and the application, but the temperature may be about 250 ℃ or about 350 ℃ in a special case, and the time may be about 10 seconds.
In the case where the object such as FPCB is directly pressed by the lower surface of the harbar machine that provides heat during the thermal welding as described above, the harbar machine is formed of metal and is hard, and therefore, when the object has irregularities or the object is not formed at a sufficient level, there is a disadvantage that the object cannot be reliably and uniformly pressed.
As another example, in the case where the lower surface of the harbar machine directly presses the solder attached to the terminal of the object, the solder is attached to the terminal of the harbar machine made of metal, or in the case where the object is difficult to form a flat surface, there is a disadvantage that the thermal welding may be poor.
In order to solve the above-described problems, according to the prior art, a protection member made of an elastic general rubber is interposed between a terminal of a haba machine and an FPCB, which is an object to be thermally welded, and thermally welded, thereby preventing the terminal of the haba machine from directly adhering to the FPCB.
The conventional protective member may be, for example, a silicone rubber sheet having a hardness of about Shore A70, a thermal conductivity of 1W/m.k or less, and a thickness of about 0.25mm and having elasticity.
As described above, in the thermal welding, the protection member made of elastic rubber is interposed between the terminal of the harba machine and the FPCB as the target object, and the thermal welding is performed.
The continuous use temperature of such a protective member is about 200 ℃, but it can withstand the heat welding operation performed in a short time.
However, the conventional protective member has the following problems.
Since the protective member does not have thermal conductivity or has low thermal conductivity, heat of the haba machine cannot be quickly transmitted to the object, and as a result, the work is slow when thermal welding is repeatedly performed.
Further, if the protection member is repeatedly used, the protection member having elasticity is easily stretched or deformed in outer shape by the harbar machine and the pressing force which are applied with high heat, and thus there is a disadvantage that the same height cannot be uniformly applied to the object and it is difficult to repeatedly use the protection member.
In particular, in the case where the protective member is continuously supplied and used in the form of a Roll (Roll), the protective member is easily stretched or deformed due to high heat, and if used in the heat welding repeated many times, a portion of the protective member directly contacting the haba machine may be easily worn or damaged due to high heat and high pressure.
As described above, at the time of thermal welding, low thermal conductivity, damage, abrasion or deformation of the protective member makes it difficult to provide reliable thermal welding, and becomes a factor that hinders continuous work.
Other conventional protective members include a heat-resistant polyimide film attached to one surface of the elastic silicone rubber sheet, or a Glass fiber (Glass fiber) embedded in the elastic silicone rubber sheet.
However, although such a polyimide film or glass fiber also serves to increase the mechanical strength of the protective member, it has a disadvantage that the thermal conductivity cannot be improved.
Also, the polyimide film has a disadvantage in that it is stretched or deformed due to high heat and high pressure, and the glass fiber has a disadvantage in that a fiber strand of the glass fiber is unwound at a cutting site.

Fig. 1 is a sectional view showing a heat conductive elastic protection member for a harbour machine according to an embodiment of the present invention, and fig. 2 is a view showing a method of applying the elastic protection member.
The thermal conductive elastic protective member 100 for a harper according to the present invention is interposed between a harper 50 and a thermal bonding film 40, and supplies heat and pressure supplied by the harper 50 to the thermal bonding film 40 and an object.
The heat conductive elastic protection member 100 for a haba machine according to the present invention is composed of a heat conductive elastic sheet 120 formed in a sheet shape and a metal foil 110 adhered to the upper surface of the elastic sheet 120.
In the following description of the present invention, adhesion may mean adhesion.
The elastic sheet 120 may be supplied in the form of a sheet having a predetermined thickness and width or a Roll (Roll) having a long length, and in the case of being supplied in the form of a Roll, the width may be 2mm to 10mm, but is not limited thereto.
The metal foil 110 is formed to be thinner than the elastic sheet 120, and the thickness of the metal foil 110 may be 1/4 or less of the thickness of the elastic sheet 120 to enable the protective member 100 to be elastically pressed. For example, the metal foil 110 may be about 0.008mm to 0.04mm, and the elastic sheet 120 may be about 0.04mm to 0.3mm, but is not limited thereto, and may be selected according to the shape and material of the facing objects.
Preferably, the metal foil 110 is a copper foil or an aluminum foil which is good in thermal conductivity and elongation and good in flexibility.
When the metal foil 110 is a copper foil, the surface in contact with the harbar 50 is exposed to the outside, and a nickel plating layer or a plating layer sequentially coated with nickel and gold may be formed on the exposed surface.
This plating prevents the surface of copper from being oxidized or corroded by the heat of the haba machine, and thus can reduce the influence of such oxidation or corrosion on the object.
In particular, in the case of using a copper foil, in order to improve the adhesion between the metal foil and the elastic sheet, micro-sized irregularities 112 may be formed on the surface of the metal foil in contact with the elastic sheet 120, and the irregularities 112 may be formed by electrolytic plating.
By forming the irregularities 112 at the boundary between the copper foil 110 and the elastic sheet 120, the liquid silicone rubber constituting the elastic sheet 120 can be filled in the irregularities 112 to increase the contact area, thereby improving the adhesive force and the thermal conductivity.
Preferably, the surface of the metal foil 110 directly contacting the harbour machine 50 is smoothly formed to improve the adhesion with the harbour machine 50, thereby improving the thermal conductivity.
The elastic sheet 120 is formed in a roll shape continuously on the surface of the metal foil 110 by Casting (Casting) a heat conductive liquid silicone rubber in which a heat conductive powder is uniformly mixed with a liquid silicone rubber on the metal foil 110 to cure the liquid silicone rubber, and adhering the liquid silicone rubber to the metal foil 110 by the self-adhesive force of the liquid silicone rubber as the liquid silicone rubber is cured.
In particular, if the electrolytic copper foil having irregularities is thermally cured after casting a liquid silicone rubber having thermal conductivity on the surface thereof, the liquid silicone rubber adheres to the metal foil having irregularities while being cured, and thus the adhesion and thermal conductivity are good.
The heat conductive powder may be an electrically insulating ceramic powder, and may be, for example, an aluminum oxide powder (Alumina powder) or an aluminum nitride powder (AlN powder), in which case the elastic sheet 120 is an electrically insulating material.
Powders having thermal conductivity and electrical conductivity such as copper powder have a disadvantage of being thermally oxidized and electrically conductive.
The protective member 100 having the elastic sheet 120 adhered to the surface of the metal foil 110 as described above is cut in a desired width to manufacture the protective member 100.
The metal foil 110 has a thermal conductivity higher than that of the elastic sheet 120, and the elastic sheet 120 may have a thermal conductivity of 0.5W/m.k to 10W/m.k. If the thermal conductivity of the elastic sheet 120 is lower than this, the thermal conductive effect is small, and if it is larger than this, the hardness becomes hard, and there is a disadvantage that it is difficult to elastically adhere to an object.
Referring to fig. 2, the protective member 100 is continuously supplied in a roll-to-roll manner between the supply roller 10 and the recovery roller 12.
As shown in fig. 1, the protective member 100 is supplied so that the metal foil 110 faces the harba machine 50, and the elastic sheet 120 is disposed so as to face the thermal bonding film 40 placed on the circuit board 30 on the support base 20.
As a result, the exposed surface of the metal foil 110 constituting the protective member 100 is brought into contact with the harba machine 50, and the exposed surface of the elastic sheet 120 is brought into contact with the film for thermal bonding 40.
In this state, the haba machine 50 presses the protective member 100 at a high temperature for a predetermined time to thermally weld the thermal adhesive film 40.
The protective member 100 allows heat from the haba machine 50 to be quickly transferred to the thermal bonding film 40 because the elastic sheet 120 as well as the metal foil 110 have thermal conductivity.
The elastic sheet 120 of the protective member 100 can be applied to an object exposed to solder, and since the elastic sheet 120 is not bonded to the solder, a continuous thermal welding operation can be realized.
With the structure and material of the protective member described in the above embodiments, even if the protective member is repeatedly used under conditions where high heat and pressure are supplied, the metal foil minimizes the stretching or deformation of the elastic sheet, and thus can supply or maintain the elastic close-fitting force with the object.
Further, since the portion directly contacting the harbar machine is a metal foil for protecting the parts, it is not easily worn, and thus replacement is not frequent, and the manufacturing cost can be reduced.
Further, since the portion directly in contact with the object is the elastic piece of the protective member, even if the solder is exposed to the object, the portion is elastically in contact with the object without adhering to the solder.
Further, since the protective member is produced by directly adhering the elastic sheet to the metal foil, and then is cut into a desired width after being produced in a roll form, productivity, thermal conductivity, and adhesive force are good.
Further, since the protective member is continuously supplied in a roll-to-roll manner, the heat welding work can be facilitated and economical efficiency can be achieved.
Fig. 3 is a sectional view showing a thermally conductive elastic protective member for a harbour machine according to another embodiment of the present invention.
The thermally conductive elastic protection member 200 according to an embodiment is composed of a thermally conductive elastic sheet 220, a metal foil 210 adhered to the elastic sheet 220, and an insulating sheet 230 having elasticity adhered to the metal foil 210.
The insulating sheet 230 has a thickness smaller than that of the thermally conductive elastic sheet 220, and the insulating sheet 230 is in contact with the harbar machine 50.
The insulating sheet 230 is provided to protect the mechanical strength of the member 200, prevent oxidation of the metal foil 210, and electrically insulate the metal foil 210, and the insulating sheet 230 may be made of polyimide, epoxy resin, or silicone rubber having heat resistance of 180 ℃.
Although the embodiments of the present invention have been described above mainly, it is obvious that various modifications can be made by those skilled in the art. Therefore, the scope of the claims of the present invention should be construed not as limited to the above-described embodiments but as defined by the scope of the claims.
