Abstract
The utility model is related to a kind of heat resistance expoxy glass felt double face copper, and one layer of surface copper foil, one layer of epoxy glass fiber cloth above, middle shellring oxygen glass felt and following one layer of epoxy glass fiber cloth and one layer of bottom surface copper foil are followed successively by from top to bottom；Expoxy glass felt described in any layer is made up of two glass mat sheets and the roving glass fiber being pressed together between glass mat sheet, the jagged structure of one side of the glass mat sheet inwardly, a face impulse- free robustness outwardly；The thickness of the epoxy glass fiber cloth is more than the thickness of expoxy glass felt, and there is epoxy glass fiber cloth filler to be mingled with structure.By the improvement to sandwich layer glass felt structure, original single layer structure is improved to the sandwich structure of roving glass fiber, the planar rigidity of glass felt is not only remained but also enhances its heat resistance, finally obtain the double face copper of a fine heat-resisting performance.
Description
Technical field
The utility model is related to the double face copper of electronic applications.
Background technology
Copper-clad plate belongs to the industrial products of a class mature, and market remains steadily increasing to the demand of copper-clad plate
Trend.In industry manufacture, with the update of digital product, the requirement to copper-clad plate is also constantly being upgraded, in addition, by
The production restriction of copper foil, the market value of high-quality copper-clad plate is increasingly highlighted.
Glass felt has the quality material that preferable planar support is rigidly copper-clad plate strengthening course, and copper is covered based on glass felt
The market quota more and more higher of plate, notification number CN202293501U utility model discloses a kind of epoxy glass mat fiberwebs and is combined
Material copper-clad plate, is made up of prepreg, glass felt and composite copper foil, and the prepreg is that epoxy resin and glass-fiber-fabric warp are folded
Combined pressure system is formed, and the prepreg interlayer glass felt is overlapped and suppressed, and glass felt is epoxy glass mat fiberwebs composite material,
Two layers of prepreg outermost is overlapped and suppressed with composite copper foil again.The utility model solves copper-clad plate temperature resistance problem.
Utility model content
The purpose of this utility model is to provide a kind of double face copper, and strengthening course is by the glass felt of sandwich layer and the glass on top layer
Fiber cloth is constituted, and can further improve the heat resistance of copper-clad plate product.
The technical scheme in the invention for solving the above technical problem is：A kind of heat resistance expoxy glass felt double-sided copper-clad
Plate, is followed successively by one layer of surface copper foil, one layer of epoxy glass fiber cloth above, middle shellring oxygen glass felt and below from top to bottom
One layer of epoxy glass fiber cloth and one layer of bottom surface copper foil；Expoxy glass felt described in any layer is by two glass mat sheets and pressing
Roving glass fiber between glass mat sheet is constituted, and the jagged structure of one side of the glass mat sheet inwardly, one side outwardly is hairless
Thorn；The thickness of the epoxy glass fiber cloth is more than the thickness of expoxy glass felt, and there is epoxy glass fiber cloth filler to be mingled with
Structure.
Preferably, the fineness of roving glass fiber is 20-40s.
Further, the filler is one of titanium dioxide, silica, titanium dioxide, ceramics, calcium carbonate.
Compared with prior art, the utility model has the advantage of：, will be original by the improvement to sandwich layer glass felt structure
Single layer structure be improved to the sandwich structure of roving glass fiber, not only remain the planar rigidity of glass felt but also to enhance its heat-resisting
Performance, in addition, setting inorganic filler to be mingled with structure the epoxy glass fiber cloth of outer layer, finally obtains a fine heat-resisting performance
Double face copper.
Brief description of the drawings
Fig. 1 is the structure decomposition figure of copper-clad plate in the utility model embodiment；
Fig. 2 is the structural representation of epoxy glass felt in the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Fig. 1 to 2, the heat resistance expoxy glass felt double face copper in the present embodiment is followed successively by table from top to bottom
One layer of face copper foil 1, one layer of epoxy glass fiber cloth 2 above, middle shellring oxygen glass felt 3 and following one layer of epoxy glass fiber
Cloth 2 and one layer of bottom surface copper foil 4.Any layer expoxy glass felt 3 is by two glass mat sheets 3.1 and is pressed together on glass mat sheet
Roving glass fiber 3.2 between 3.1 is constituted, the jagged structure of the one side of glass mat sheet inwardly, a face impulse- free robustness outwardly.Expoxy glass
The thickness of fiber cloth 2 is more than the thickness of expoxy glass felt 3, and there is epoxy glass fiber cloth filler to be mingled with structure, and filler is two
Silica.
The fineness of roving glass fiber 3.2 in the present embodiment is 40s, bunchy laying.
The double face copper of said structure has more excellent heat resistance.
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
