Abstract
The utility model relates to an epoxy-fiberglass-cloth CCL (copper-clad plate), which is mainly used on a circuit-board base plate of an object such as a television, a display, a VCD, a power switch, a regulator, and the like. The CCL is formed in the ways as follows: laminated sheets (1) and prepregs (2) are arranged at intervals and stacked to form a laminated product, and one side of the laminated product is clothed in copper foil (3); the laminated sheets (1) adopt epoxy-fiberglass-cloth laminated sheets, the prepregs (2) adopt epoxy-fiberglass-cloth prepregs (2), and layers of the laminated sheets (1) are 3 to 6, and layers of the prepregs (2) are 2 to 5. According to the utility model, the laminated sheets (1) are manufactured to have a thinner shape which is 3-5 ply; the thinner the plate, the better the levelling property; material in the middle can extend to the periphery during hot-pressing process, the peripheral multipoint thickness deviation of the CCL surface is small and is about plus/minus 1% as great as the thickness; the thickness uniformity is good; and the performance of the CCL is ensured.
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 copper-clad plate in the past was by the multilayer epoxy glass cloth prepreg laminated product that is formed by stacking, and at a composite copper foil 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 the less epoxy glass cloth copper-clad plate of multiple spot thickness deviation on every side of a kind of laminated product plate face is provided.
The purpose of this utility model is achieved in that the copper-clad plate of a kind of epoxy glass cloth, be by laminate and the prepreg laminated product that is formed by stacking at interval, and at a composite copper foil 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.
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 copper-clad plate.
Reference numeral among the figure:
Laminate 1, prepreg 2, Copper Foil 3.
(5) specific embodiment
Referring to Fig. 1, the epoxy glass cloth copper-clad plate that the utility model relates to, be by laminate 1 and prepreg 2 laminated product that is formed by stacking at interval, and at a composite copper foil 3 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 copper-clad plate, 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 the composite copper foil (3) 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, and prepreg (2) is an epoxy glass cloth prepreg.
