Embodiment Construction

[0026] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail:

[0027] Such as Figures 1 to 4 As mentioned above, first prepare a clean FR4 sheet (glass fiber epoxy resin copper clad laminate) 1, such as figure 1 as shown, and then make groove 2, such as figure 2 As shown, the cross-sectional size of the groove is the diameter of the standard optical fiber 3, and then place the optical fiber 3 in the groove 2, such as image 3 shown. Finally, after the pressing process, the optical fiber 3 will be embedded in the printed circuit board to form an optical layer, and the general copper lines 4 can continue to be distributed on the surface of the circuit board, such as Figure 4 shown.

[0028] refer to Figure 5 , After forming the optical layer, the most critical issue is how to couple the light in and out, and how to turn the light by total reflection. Using the above-mentioned bevel cutting method, ...

Abstract

The invention provides a manufacture method of an optical printed wiring board. The manufacture method of the optical printed wiring board includes the following steps: a step of opening a groove, a step of pressing a plate, a step of cutting out an angle, a step of polishing a laser surface and a step of drilling a hole on the back. The manufacture method of the optical printed wiring board has the advantages that a bottleneck of electric mutual connection broadcasting brand width on a conventional printed wiring board is broken through and signal broadcasting brand width can be higher than 10 gigabytes / second. Besides, conventional optical components such as a vertical cavity face emitting laser device. An optical sensor and the like can be also inserted on a wiring board face. The wiring board face is compatible with an existing surface mount technology and the development potential for mass production.

Description

technical field [0001] The invention relates to an optical printed circuit board. Background technique [0002] As future computer systems increasingly require higher transmission requirements, traditional printed circuit board (PCB) metal-based electronic circuits are limited by physical limitations, such as signal interference, impedance matching, transmission loss, etc. performance of the entire system. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for manufacturing an optical printed circuit board, comprising the following steps: slotting step, plate pressing step, angle cutting step, laser surface grinding step, and backside drilling step. [0004] Optical printed circuit board is a solution for high-speed transmission. It can use light waves as the medium of signal transmission, and can provide data rates above 10Gb / s, and has the advantages of low power consumption and immunity to electrom...
