The project is listed under Rigid-Flex PCB services, which are specialized circuits that combine both rigid and flexible substrates, often used in compact or complex electronic assemblies like wearables or folding devices. 21182.rar
The PCBWay manufacturing guidelines indicate that their automated systems will use the internal parameters of the files regardless of external selection menus (such as via filling options) unless specifically noted in the engineering instructions. Use a tool like VirusTotal to check the file
For rigid-flex designs, it is critical that the .rar includes specific layers for the coverlay (the flexible outer layer) and clear definitions of the transition zones between rigid and flex sections to avoid mechanical failure. Security Warning For rigid-flex designs, it is critical that the
The .rar file serves as the package for the manufacturer to interpret circuit layers, drill holes, and component placement. Technical Review
