Abstract
The utility model provides an optical printed circuit board. The optical printed circuit board comprises a printed circuit board and a prepreg, wherein more than one groove is arranged on the printed circuit board, an optical fiber is placed in the groove, the prepreg is placed on the optical fiber, the prepreg and the optical fiber are bonded in a pressing way, and the optical fiber finally cuts a bevel edge. The optical printed circuit board provided by the utility model has the advantages that the conventional optical components of a vertical cavity surface emitting laser, an optical sensor and the like can be directly inserted on a surface of the circuit board by the optical printed circuit board, thereby being compatible with the existing surface mount technology, and further having a development potential of mass production.
Description
Technical field
The utility model relates to a kind of optical printed circuit board.
Background technology
Along with the calculator system in future more and more needs higher transmission requirement, traditional printed circuit board (PCB) (PCB) is take the electronic circuit of metal as the basis, owing to being subject to physical restriction, all limited the performance of whole system as signal interference, impedance matching, loss etc.
Summary of the invention
In order to solve above technical matters, the utility model provides a kind of optical printed circuit board, comprise printed circuit board (PCB) and prepreg, be provided with more than one groove on described printed circuit board (PCB), be placed with optical fiber in described groove, be placed with prepreg on described optical fiber, described prepreg and described optical fiber bond by pressing.
Preferably, described optical printed circuit board is provided with the hypotenuse that utilizes bevelling machine that described fiber cut is gone out.
Preferably, described optical printed circuit board is provided with the hypotenuse that utilizes the laser machine that described fiber cut is gone out.
Preferably, described optical printed circuit board is provided with the hypotenuse that utilizes the V-arrangement cutting machine that described fiber cut is gone out.
Preferably, the width of groove and the equal diameters of height with described optical fiber.
Preferably, on the xsect of described optical fiber through the laser polishing.
Preferably, after described cutting, the prepreg at the back side of optical fiber need to utilize laser technology that it is removed.
Optical printed circuit board is a kind of scheme that can solve high-speed transfer, and it can make with light wave the medium of signal transmission, and the above data rate of 10Gb/s can be provided, and has low-power consumption and be not subjected to the advantage such as Electromagnetic Interference.The beneficial effects of the utility model are: this optical printed circuit board can directly be inserted in traditional optical module such as vertical cavity surface emission laser device and optical sensor etc. on the circuit board face, compatible existing surface mounting technology not only, and have the development potentiality of large-scale production.

Embodiment
Below in conjunction with accompanying drawing, more excellent embodiment of the present utility model is described in further detail:
As described in Fig. 1 to 4, at first prepare a clean FR4 sheet material (glass-epoxy copper-clad plate) 1, as shown in Figure 1, then leave groove 2, as shown in Figure 2, the sectional dimension of groove is standard fiber 3 diameters, then place optical fiber 3 at groove 2, as shown in Figure 3.At last, through the pressing plate program, optical fiber 3 can be embedded into and form photosphere in printed circuit board (PCB), and general copper wire 4 can continue to be distributed in circuit board surface, as shown in Figure 4.
With reference to figure 5, after forming photosphere, the problem of most critical is how optically-coupled to be passed in and out, and utilizes light total reflection to carry out corner.Use above-mentioned hypotenuse patterning method, then after another side copper and prepreg part are removed, light source 5 just can vertically enter optical fiber 2 then vertical output to optical sensor 6.Such benefit is that all electronic components are comprised that laser light source and optical sensor can be put into the top layer of circuit board, thus compatible existing surface mounting technology (SMT).
With reference to figure 6, laser is the laser light of utilizing 7 outputs of CO2 Lasers machine.The output energy of this laser can change by time shutter and laser power.And the sample 8 that needs polishing is placed on the tall and erect platform 9 of computer-controlled three-dimensional optical, needs like this position of polishing just can accurately control.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
