Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings.
Referring to fig. 2, the present invention provides a photoelectric glass fiber fabric, including: an electronic glass fiber 1; the optical fiber 2, the electronic glass fiber 1 and the optical fiber 2 are co-woven together. In the prior art, electronic glass fiber cloth is woven to form the electronic glass fiber cloth, and the electronic glass fiber cloth is used as a support structure of a prepreg. The electronic glass fiber 1 and the optical fiber 2 are woven to form photoelectric glass fiber cloth which can also be used as a support structure of a prepreg; and the optical fiber 2 serves as a transmission channel of the optical signal. Because the optical fiber 2 is woven into the photoelectric glass fiber cloth, the optical fiber does not need to be additionally arranged outside the photoelectric glass fiber cloth and subsequent products, namely a prepreg and a circuit board, and the space is saved.
The photoelectric glass fiber cloth has a warp direction A and a weft direction B, and the warp direction A and the weft direction B are crisscross. In the warp direction a or the weft direction B, the optical fiber 2 is longer than the electronic glass fiber 1, and both ends 21, 22 of the optical fiber 2 are beyond both ends of the electronic glass fibers 11, 12. Specifically, in the warp direction a, the optical fiber 2a is longer than the electronic glass fiber 1a, the first end 21a of the optical fiber 2a is in an outward direction of the first end 11a of the electronic glass fiber (in terms of the electronic glass fiber 1a as a center, the warp direction a as a contrast direction), and the second end 22a of the optical fiber 2a is in an outward direction of the second end 12a of the electronic glass fiber; similarly, in the weft direction B, the optical fiber 2B is longer than the electronic glass fiber 1B, the first end 21B of the optical fiber 2B is in an outward direction of the first end 11B (in the warp direction B as a comparison direction with the electronic glass fiber 1B as a center), and the second end 22B of the optical fiber 2B is in an outward direction of the second end 12B of the electronic glass fiber. Therefore, after the photoelectric glass fiber cloth is subjected to relevant subsequent processing, when a circuit for transmitting optical signals by the optical fibers is manufactured, the optical fibers all protrude out of the electronic glass fibers, and the end parts of the optical fibers can be well found.
Referring to fig. 2, in the weft direction, the second, fifth, sixth, eighth, and tenth optical fibers are optical fibers, and in the warp direction, the second, third, sixth, and ninth optical fibers are optical fibers.
The ends 21 and 22 of the optical fiber 2 are sealed with a high-temperature resistant resin 3. Accordingly, impurities can be prevented from entering the inside of the passage of the optical fiber 2 in the subsequent processing.
The optical fiber is inorganic optical fiber or high temperature resistant organic optical polymer fiber. The optical fiber can be optical glass fiber and the like, and the optical fiber meets the requirements of the prior prepreg on the dielectric property and the like of the original glass fiber cloth.
And immersing the photoelectric glass fiber cloth into glue, and coating the glue on the photoelectric glass fiber cloth to form a prepreg. The prepreg can be laminated with a conducting wire and a carved circuit line or etched after copper foil is laminated to form a circuit board, the conducting wire part is responsible for electric transmission, and the photoelectric glass fiber cloth formed by co-weaving of optical fibers and electronic glass fibers can meet the dielectric property of the glass fiber cloth in the original prepreg.
In order to manufacture the photoelectric glass fiber cloth, the invention also provides a manufacturing method of the photoelectric glass fiber cloth, which is used for co-weaving the electronic glass fiber and the optical fiber together to form the photoelectric glass fiber cloth.
Weaving the electronic glass fiber and the optical fiber together by adopting a warp and weft crisscross weaving method; the optical fiber is longer than the electronic glass fiber in the warp direction or the weft direction, respectively, and the optical fiber is placed at both ends of the optical fiber beyond both ends of the electronic glass fiber; sealing the ports of the two ends of each optical fiber by adopting high-temperature-resistant resin; the optical fiber is inorganic optical fiber or high temperature resistant organic optical polymer fiber.
Immersing the photoelectric glass fiber cloth into the glue of the binder to form a prepreg, solidifying and bonding the prepreg and the conductor into an integrated circuit board through a vacuum heating and pressing process,
the high temperature resistance means that the high temperature resistant resin and the high temperature resistant organic photoconductive polymer fiber are kept in a solid state at the curing process temperature of the binder. In the laminating process of the prepreg, heating and pressurizing are required, and the high-temperature resistant resin is kept in a solid state and cannot be melted to form a flowing state in order to avoid impurities entering the optical fiber tube in the process. The optical fiber also does not melt during the lamination process and retains its original structural characteristics.
The conductor is formed by etching after being adhered by copper foil, or by a line-planting and pressing method, or by pressing an engraved line. The circuit is formed by the method of the printed circuit board, the circuit is formed by the method of the wire-planting circuit board, and the circuit is formed by the method of firstly forming the engraving circuit and then pressing.
After the circuit board is formed, the high-temperature resistant resin sealing the two ends of the optical fiber is cut off, and the optical signal transmission receiver is connected. Accordingly, an optical signal can be transmitted through the optical fiber embedded in the co-woven photoelectric glass fiber cloth.
The above description is a specific embodiment of the photoelectric glass fiber cloth and the manufacturing method thereof provided by the present invention. Accordingly, the present invention provides a novel glass fiber cloth and a method for manufacturing the same, wherein the novel glass fiber cloth can be simultaneously applied to a circuit board and optical signal transmission, and can be defined as a photoelectric glass fiber cloth, and the novel glass fiber cloth is interwoven by co-weaving electronic glass fibers and inorganic optical fibers or organic optical polymer fiber materials with low transmission loss and high temperature resistance to form a novel photoelectric glass fiber cloth and is applied to a circuit board manufacturing process, so that respective transmission of electrical signals and optical signals is realized, a photoelectric conversion process is reduced, signals are directly transmitted, transmission efficiency is high, arrangement of photoelectric conversion devices on the printed circuit board or a photoelectric packaging carrier plate is reduced, laying of optical cables is saved, manufacturing cost is reduced, and space utilization rate and wiring density of the PCB substrate are indirectly increased.
