This utility model relates to the field of electronic component technology and discloses a mounting integration assembly. The assembly includes multiple mounting components and bridging components on a tape. Multiple mounting components for mounting components are integrated into a single unit, with one side of each component serving as the mounting surface. Bridging components are retained to fix the relative positions of the multiple mounting components, ensuring consistent spacing and dimensions. An adhesive backing is attached to the side of the tape away from the mounting surface, fixing all mounting components to the backing. This ensures that even after removing the bridging components, the relative positions of the multiple mounting components remain stable, without affecting the spacing and coplanarity of the components before mounting. This assembly allows for the simultaneous mounting of multiple components onto components and is suitable for mounting components of various specifications, achieving multi-functional integration of components, improving mounting efficiency and effectiveness. The operation is simple, easily automatable, and ensures mounting reliability and stability.
