Flex Capability

Flex Capability

For Flex Capability, Material selection, process tolerances, manufacturing logistics, and your flex supplier all play an important role in producing a cost-effective circuit designing. Additionally, it is equally important for the maintenance of reliable flex circuit design.

At Rushpcb assembly will assist you in design for manufacturing to minimize overall program costs. Nevertheless, you can trust our services without a doubt. But, make it sure that you are sharing the complete detail and information.

Thus, Listed are standard materials and capabilities.

So, Come speak with us and tell us should your design require tighter tolerances or special process treatments.
