Abstract
The utility model discloses a new CEM-3 copper-clad plate including a glass mat layer; glass fiber cloth layers are arranged on both sides of the glass mat layer, and copper foil layers coat the outer surface of the glass fiber cloth layers; the glass fiber cloth layers are prepared by bonding a plurality of sheets of short glass fiber cloth and a plurality of sheets of long glass fiber cloth, the short glass fiber cloth length is at most 7mm, the long glass fiber cloth length is at least 13mm,and the glass mat layer, the glass fiber cloth layers and the copper foil layers are pressed into a whole. The new CEM-3 copper-clad plate solves the problems that in the process of machining, especially during heat treatment, the copper-clad plate dimension change is large, and the buckling deformation is large, and the new CEM-3 copper-clad plate is strong in practicability, and worthy of promotion.
Description
Technical field
The utility model relates to copper-clad plate processing technique field, relates in particular to a kind of novel C EM-3 copper-clad plate.
Background technology
At present, glass fiber paper is generally the glass fibre by diameter 9-10 μ m, length 13mm left and right, by adhesive is bonding, makes.The CEM-3 copper-clad plate of being made by this glass fiber paper, in process, especially during heat treatment, buckling deformation is large.Glass fiber paper in the past, because density is little, space is many, during gluing, resin content is large.The CEM-3 copper-clad plate of being made by this glass fiber paper, when heat treated, change in size is inevitable large.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of novel C EM-3 copper-clad plate.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of novel C EM-3 copper-clad plate, comprise glass carpet veneer, described glass carpet veneer both sides are glass layer of cloth, the outer surface of glass layer of cloth is covered with copper foil layer, and roving glass fiber cloth is bonding makes by multiple short glass fiber cloth and multiple for described glass layer of cloth, and short glass fiber cloth length is at most 7mm, roving glass fiber cloth length is at least 13mm, and described glass carpet veneer, glass layer of cloth and copper foil layer are pressed into an integral body.
Further, described glass carpet veneer is formed by stacking by least three glass mats.
Compared with prior art, roving glass fiber cloth is bonding makes by multiple short glass fiber cloth and multiple for glass layer of cloth of the present utility model, so just makes the gap smaller between glass layer of cloth, has improved the density of glass layer of cloth, make glass layer of cloth when gluing, amount of resin reduces, resin content is even.The dimensional stability of the CEM-3 copper-clad plate of making thus can improve, and practical, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the novel C EM-3 copper-clad plate the utility model proposes, comprise glass carpet veneer 1, glass carpet veneer 1 both sides are glass layer of cloth 2, the outer surface of glass layer of cloth 2 is covered with copper foil layer 3, roving glass fiber cloth is bonding makes by multiple short glass fiber cloth and multiple for glass layer of cloth 2, and short glass fiber cloth length is at most 7mm, and roving glass fiber cloth length is at least 13mm; Glass carpet veneer 1 is formed by stacking by least three glass mats; And described glass carpet veneer 1, glass layer of cloth 2 and copper foil layer 3 are pressed into an integral body.
In the utility model, by the short glass fiber cloth with below 7mm, fill the space in glass layer of cloth, thereby improve the density of glass layer of cloth, make glass layer of cloth when gluing, amount of resin reduces, resin content is even, and the dimensional stability of the CEM-3 copper-clad plate of making thus can improve.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
