Flexible printed circuits for wearable devices, camera modules, sensors, and compact interconnects. XinshunPCB helps align materials, bend requirements, coverlay, and connector reinforcement with your design, from prototype builds to production.
Custom Flex PCBs for Compact Electronic Designs
Flexible printed circuits for wearable devices, camera modules, sensors, and compact interconnects. XinshunPCB helps align materials, bend requirements, coverlay, and connector reinforcement with your design, from prototype builds to production.
Plan flexible connections around your available space, bending needs, and assembly requirements.
Flexible PCBs connect components and modules where space and routing are constrained. XinshunPCB supports flexible circuit projects with material and stackup review, coverlay planning, and reinforced connector areas. Share your drawings and intended bend conditions so the construction can be reviewed for installation and use.
Browse selected flexible circuit builds and review their construction, materials, and application details. Use these examples to discuss the right interconnect design for your project with XinshunPCB.
Explore construction options, materials, dimensions, circuit features, surface finishes, and test parameters for flexible circuits. Rigid-flex layer counts and thicknesses are listed separately where applicable. Contact us to review the requirements of your specific design.

Repeated bending must be specified as part of the design requirements. A circuit that bends during installation may need a different construction from one that moves throughout its service life. Provide the bend radius, direction of motion, expected cycle count, operating temperature, and mechanical constraints. Material selection, copper, stackup, and routing should be reviewed together, with any required cycle testing agreed before production.
