Abstract
The utility model relates to an epoxy glass fiber cloth double-sided copper-clad plate, which is mainly used for circuit board substrates of television sets, displays, video compact disks (VCD), power switches, adjusters and the like. The copper-clad plate is a laminated product which is formed by laminating 3 to 6 layers of laminated plates (1) and 2 to 5 layers of prepregs (2) at intervals, wherein copper foils (3) are compounded on the upper surface and the lower surface of the laminated product; the laminated plate (1) is an epoxy glass fiber cloth laminated plate; the prepreg (2) is an epoxy glass fiber cloth prepreg; and the epoxy glass fiber cloth laminated plate is the laminated product which is formed by laminating a plurality of layers of prepregs. In the copper-clad plate, the laminated plate can be made thinner (3 to 5 layers), and the thinner plate has better leveling property and thus, the middle material can be extended to the periphery during hot pressing, the thickness deviation of a plurality of points around the surface of the copper-clad plate is extremely small, the deviation is only about +1/-1 percent of the thickness, thickness uniformity is high, and the performance of the copper-clad plate can be guaranteed.
Description
(1) technical field
The utility model relates to a kind of copper-clad plate.Be mainly used in the wiring board substrate of television set, display, VCD, power switch, adjuster etc.
(2) background technology
Before the utility model was made, epoxy glass cloth double face copper in the past was by the multilayer epoxy glass cloth prepreg laminated product that is formed by stacking, and at two composite copper foils up and down of described laminated product.Its shortcoming is that the multiple spot thickness deviation is very big around the laminated product plate face, deviation reach thickness ± about 10%, laminated product thickness uniformity is relatively poor.This has had a strong impact on the performance of copper-clad plate.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of laminated product plate face less epoxy glass cloth double face copper of multiple spot thickness deviation on every side is provided.
The purpose of this utility model is achieved in that a kind of epoxy glass cloth double face copper, be by laminate and the prepreg laminated product that is formed by stacking at interval, and at two composite copper foils up and down of described laminated product, described laminate has 3～6 layers, prepreg has 2～5 layers, described laminate is the epoxy glass fabric laminates, and prepreg is an epoxy glass cloth prepreg, and described epoxy glass fabric laminates is by the multilayer epoxy prepreg laminated product that is formed by stacking.
The beneficial effects of the utility model are:
The utility model can be made laminate thinlyyer, thin more plate current levelling is good more, material in the middle of can making in the process of hot pressing like this extends to the periphery, the multiple spot thickness deviation is very little around the copper-clad plate plate face, deviation only is thickness ± about 1%, the thickness uniformity is better, can guarantee the performance of copper-clad plate like this.
(4) description of drawings
Fig. 1 is the section structure schematic diagram of the utility model epoxy glass cloth double face copper.
Reference numeral among the figure:
(5) specific embodiment
Referring to Fig. 1, the epoxy glass cloth double face copper that the utility model relates to, be by laminate 1 and prepreg 2 laminated product that is formed by stacking at interval, and at two composite copper foils 3 up and down of described laminated product, described laminate 1 is the epoxy glass fabric laminates, prepreg 2 is an epoxy glass cloth prepreg, and described laminate 1 has 3～6 layers, and prepreg 2 has 2～5 layers.
Described epoxy glass fabric laminates is that epoxy glass cloth prepreg is to be soaked with the epoxy resin semi-solid preparation by the electron level alkali-free glass fiber cloth to form by the multilayer epoxy prepreg laminated product that is formed by stacking.
Claims (1)
1. epoxy glass cloth double face copper, it is characterized in that described copper-clad plate is by laminate (1) and prepreg (2) laminated product that is formed by stacking at interval, and at two composite copper foils (3) up and down of described laminated product, described laminate (1) has 3～6 layers, prepreg (2) has 2～5 layers, described laminate (1) is the epoxy glass fabric laminates, prepreg (2) is an epoxy glass cloth prepreg, and described epoxy glass fabric laminates is by the multilayer epoxy prepreg laminated product that is formed by stacking.
