Manufacturing method of flexible board optical fiber line device

Abstract

The invention discloses a flexible board optical fiber line device making method, which comprises a preparation step, a processing step, a laying step, and a fixing step. In the preparation step, a base unit and multiple optical fibers with multiple colors are prepared, and the base unit comprises a substrate, a back adhesive layer applied to the substrate and a protective paper detachably attached to the back adhesive layer. In the processing step, the protective paper is cut to form a groove region for laying the optical fiber. In the laying step, according to a to-be-laid path, the colors are used as the optical fiber laying order, and the optical fibers are sequentially laid in the groove region. In the fixing step, the protective paper attached to the back adhesive layer is removed, aprotective material is sprayed on the back adhesive layer and the optical fiber, and the optical fiber laid on the back adhesive layer is thus fixed.

Description

technical field [0001] The invention relates to a method for manufacturing an optical fiber circuit device, in particular to a method for manufacturing a flexible board optical fiber circuit device. Background technique [0002] refer to figure 1 , is an existing method for manufacturing a flexible board for optical fiber circuits. Firstly, a base material 10 of a flexible board is prepared, and a primer layer 11 is coated on the base material 10 . Then, through the viscosity of the primer layer 11 , the optical fiber 12 can be directly laid on the substrate 10 to form a required optical fiber network. Finally, a protective coating 13 is sprayed on the base material 10 and the laid optical fibers 12 to cover the primer layer 11 and the laid optical fibers 12, and the manufacture of the optical fiber circuit flexible board is completed. [0003] In addition to directly completing a relatively complex network arrangement on the substrate 10, the optical fiber line flexible b...

Problems solved by technology

Therefore, when laying the optical fiber 12 on the primer layer 11, as long as there is a slight deviation in the position of any optical fiber 12 when laying, it will be fixed on the substrate 10 immediately due to the viscosity of the primer layer 11. Because the material of the optical fiber 12 is relatively soft and brittle, it is very easy to be damaged when subjected to a pulling force, so it is impossible to remove the incorrectly routed optical fiber 12 from the primer layer 11 and then redo it.

In addition, in order to make the optical fiber 12 easy to identify when connecting, usually a variety of optical fibers 12 of different colors are used for identification, but the optical fibers 12 of different colors need to be replaced constantly during laying, which will cause the laying efficiency to drop. , it is difficult to effectively improve the manufacturing efficiency of optical fiber circuit flexible boards
