Description

Technical Field

[0002] In the production and processing of flexible circuit board products, it is sometimes necessary to assemble MIC (Microphone) components on the flexible circuit board. Moreover, in the process of assembling the MIC components, it is necessary to stick a protective film on the MIC components to prevent foreign matter from entering the components. Moreover, after the MIC components are assembled, the protective film on the MIC components needs to be torn off; or, before assembling the MIC components on the flexible circuit board, the protective film on the MIC components needs to be torn off.

[0003] In traditional technologies, some technologies use film tearing equipment to peel off the protective film on the MIC component, but they still manually take the flexible circuit board assembled with the MIC component or the carrier board loaded with the MIC component (or the flexible circuit board assembled with the MIC component) (i.e., the material) and place it in the film tearing equipment for film tearing, and then manually take the material away after the film tearing is completed, which reduces the film tearing efficiency.
