1. The rigid flex board is to glue one or more rigid layers on the flexible board. The circuit on the rigid and flexible layersare connected through metallization. Each rigid-flex board has one or more rigid areas and a flexible zone.
2. The combination of one flexible board and several rigid boards, and the combination of several flexible boards and several rigid boards.
The electrical interconnection is realized by drilling, plating holes, and laminating processes. According to the design requirements, the design concept is more suitable for installing and debugging the device and the welding operation. The installation of the assembly is more flexible.
