Abstract
The utility model relates to an epoxy phenolic aldehyde bleached wood fiber paper and glass cloth single-sided copper-clad plate used for a high-power electronic component as a substrate of a PCB (printed circuit board). The copper-clad plate is formed through the compounding of a copper foil (1), a glass cloth I (2), 4 to 6 layers of bleached wood fiber paper (3) and a glass cloth II (4) in sequence from top to bottom, wherein the bleached wood fiber paper (3), the glass cloth I (2) and the glass cloth II (4) all soaked with epoxy phenolic aldehyde resin. The copper-clad plate has the following characteristics: the 4 to 6 layers of wood fiber paper are adopted to replace the original two-layer cotton fiber paper, which enhances the intensity of the copper-clad plate; therefore, the copper-clad plate can be used for manufacturing the substrate of the PCB of the high-power electronic component.
Description
(1) technical field
The utility model relates to a kind of copper-clad plate.Be used for high-power electronic component and make the substrate of printed substrate.
(2) background technology
Before the utility model is made, be used for high-power electronic component in the past and make the material of the substrate of printed substrate and mostly adopt the copper-clad plate of two layers of phenolic aldehyde bleached cotton fiber paper.By the printed substrate weak strength that this copper-clad plate is made, subject to damage in vibration environment.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of intensity strong epoxy novolac bleaching wood-fibred paper glass cloth single-side coated copper plate.
The purpose of this utility model is achieved in that a kind of epoxy novolac bleaching wood-fibred paper glass cloth single-side coated copper plate, described copper-clad plate from top to bottom successively by Copper Foil, glass cloth I, bleaching wood-fibred paper and glass cloth II totally four layers be composited, wherein bleaching wood-fibred paper 3 has 4～6 layers again, and described bleaching wood-fibred paper, glass cloth I and glass cloth II all are soaked with epoxy phenolics.
Characteristics of the present utility model are:
The utility model adopts 4～6 layers of wood-fibred paper to substitute original two layers of coton paper, has strengthened the intensity of copper-clad plate, and the printed wire that therefore can be used to make high-power electronic component is made substrate.
(4) description of drawings
Fig. 1 is the section structure schematic diagram of the utility model epoxy novolac bleaching wood-fibred paper glass cloth single-side coated copper plate.
Among the figure: Copper Foil 1, glass cloth I 2, bleaching wood-fibred paper 3, glass cloth II 4.
(5) embodiment
Referring to Fig. 1, the epoxy novolac bleaching wood-fibred paper glass cloth single-side coated copper plate that the utility model relates to, described copper-clad plate from top to bottom successively by Copper Foil 1, glass cloth I 2, bleaching wood-fibred paper 3 and glass cloth II4 totally four layers be composited, wherein bleaching wood-fibred paper 3 has 4～6 layers again, and described bleaching wood-fibred paper 2, glass cloth I 2 and glass cloth II 4 all are soaked with epoxy phenolics.
Claims (1)
1. an epoxy novolac is bleached wood-fibred paper glass cloth single-side coated copper plate, it is characterized in that described copper-clad plate from top to bottom successively by Copper Foil (1), glass cloth I (2), bleaching wood-fibred paper (3) and glass cloth II (4) totally four layers be composited, wherein bleaching wood-fibred paper (3) has 4～6 layers again, and described bleaching wood-fibred paper (2), glass cloth I (2) and glass cloth II (4) all are soaked with epoxy phenolics.
