Rigid-Flex PCB Advantages
1. Survive high levels of shock and vibration
2. Survive hundreds of thousands of flex cycles
3. Reduce package weight
4. Increase circuit density
5. Decrease necessary assembly operations
Rigid-Flex PCB Applications
Rigid flex boards are extremely versatile and can be tailored to applications across a wide range of industries. They are highly suitable for military, aerospace, and medical devices, but they can also be implemented towards certain commercial products.
LHD will make this innovation according to the requirements of our customers and the expertise of our engineers. Achieve three-dimensional assembly, saving assembly space and making electronic products smaller and lighter.
