FR4-FLEX/M-VIA Flex®
FR4-FLEX/M-VIA Flex® is rigid-flex PCB without polyimide and can be utilized for applications that do not require repeated bending. Meiko has two types of Rigid-Flex PCB without polyimide, and FR4-FLEX achieved low-cost and high-reliability PCBs by using ordinary FR-4 only as the primary material. On the other hand, M-VIA Flex® improves flexibility by combining RCC and FR-4 as primary materials.
FR4-FLEX/M-VIA Flex® can be used as an alternative to connectors to reduce process load and cost by reducing connectors.
Features
- Reduction in process load and cost by reducing connectors
- Offer of the three-dimensional structure and larger capacity of multiple memories
- Zo design of flexible sections and improved transmission quality
Applications
FR4-FLEX
- Automotive devices
- Amusement
M-VIA Flex®
- Consumer devices
- Mobile terminals

Rigid-Flex PCB
These PCBs integrate flexible PCBs and rigid PCBs. Because connectors are not required for connection between layers, they are ideal for digital devices that are vulnerable to noise effect.
