Abstract
The utility model discloses a copper-clad glass fiber felt composite laminate, which belongs to the technical field of copper-clad laminates. The technical key of the copper-clad glass fiber felt composite laminate is that the copper-clad glass fiber felt composite laminate comprises a copper foil layer, wherein the base layer under the copper foil layer consists of two epoxy resin-impregnated glass fiber fabric layers with the same thickness and three epoxy resin-impregnated glass fiber felt layers with the same thickness, which are laminated together, and the three epoxy resin-impregnated glass fiber felt layers are laminated between the two epoxy resin-impregnated glass fiber fabric layers. The utility model has the advantages of stable quality and little warpage, and is applied to circuit boards.
Description
Technical field
The utility model relates to a kind of copper-clad plate, and more particularly, it relates to a kind of compound base veneer sheet of Copper Foil glass fibre felt-cloth that covers.
Background technology
Traditional compound base veneer sheet of Copper Foil glass fibre felt-cloth (being the CEM-3 plate) that covers is common circuit sheet material material such as photoelectric lighting, power supply board, household electrical appliance, electronic musical instrument.At present, the basal layer of CEM-3 plate be five layer by layer between structure, adopt two-layer same thickness dipped glass fibre cloth and three layers of different-thickness impregnated glass fibre carpet veneer to press and form, the glass cloth base material thickness in the wherein two-layer dipped glass fibre cloth is 0.22mm, coating weight 405g/m
2, the wherein layer of glass felt weight in three layers of impregnated glass fibre felt is 75g/m
2, coating weight 490g/m
2, two-layer in addition glass mat weight is 105g/m
2, impregnation resin content 660g/m
2This interlayer structure finds that in use the angularity of laminate also is not very good, and the angularity of plate has further improved necessity more than 0.75%, to improve the wiring board quality.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, provide a kind of steady quality, angularity little cover the compound base veneer sheet of Copper Foil glass fibre felt-cloth.
The technical solution of the utility model is such: a kind of compound base veneer sheet of Copper Foil glass fibre felt-cloth that covers, comprise copper foil layer, the basal layer of wherein said copper foil layer bottom is that the system of laminating layer by layer of the epoxy resin-impregnated glass mat by the epoxy resin-impregnated glass fibre layer of cloth of two-layer same thickness and three layers of same thickness constitutes, and three layers of epoxy resin-impregnated glass mat are stacked between the two-layer epoxy resin-impregnated glass fibre layer of cloth layer by layer.
The middle layer by layer glass mat base material weight of above-mentioned a kind of covering in the compound base veneer sheet of Copper Foil glass fibre felt-cloth, described epoxy resin-impregnated glass mat is 105g/m
2, impregnation resin content 600g/m
2
Above-mentioned a kind of covering in the compound base veneer sheet of Copper Foil glass fibre felt-cloth, the glass fabric base material thickness is 0.22mm in the described epoxy resin-impregnated glass fibre layer of cloth, coating weight 385g/m
2
After the utility model adopts said structure, by adopting the epoxy resin-impregnated glass mat of three layers of same thickness, and the impregnation resin content of adjustment glass mat, solve effectively because of fiberglass-based felt performance is inconsistent and cause the bigger deficiency of laminate angularity, the angularity of laminate can be controlled at below 0.5%.
Description of drawings
Below in conjunction with the specific embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the interlayer structure schematic diagram of a kind of specific embodiment of the utility model.
The specific embodiment
Consult shown in Figure 1, a kind of compound base veneer sheet of Copper Foil glass fibre felt-cloth that covers of the present utility model, comprise copper foil layer 1, the basal layer of present embodiment copper foil layer 1 bottom is that the epoxy resin-impregnated glass fibre carpet veneer 3 stacked compactings by the epoxy resin-impregnated glass fibre layer of cloth 2 of two-layer same thickness and three layers of same thickness constitute, and three layers of epoxy resin-impregnated glass fibre carpet veneer 3 are layered between the two-layer epoxy resin-impregnated glass fibre layer of cloth 2; The glass fabric base material thickness is 0.22mm in the two-layer epoxy resin-impregnated glass fibre layer of cloth 2 in the present embodiment, and the coating weight of epoxy resin is 385g/m
2, glass mat base material weight is 105g/m in 3 layers of three layers of epoxy resin-impregnated glass fibre carpet veneers
2, coating weight 600g/m
2Copper-clad plate angularity behind the lamination is controlled at below 0.5%, has reached the technique effect of expection.
