Flex and rigid-flex PCBs.

Flex your design potential with Sierra Circuits

Get flex and rigid-flex PCBs manufactured in the United States at any volume. Sierra Circuits leads the industry in quality and turnaround times.

• Freedom of designThe elastic nature of flexible PCBs allows for placement around edges and folds.
• Reduced space and weightFlex circuit’s polyimide material is lighter than FR4. The use of flexible flat cables (FCC) take up less space than traditional wires.
• Increased reliability and durabilityFlex circuits can be significantly warped/deformed without breakage. Standard materials can withstand as many as 200,000 bending cycles.
• Improved heat dissipation and airflowPolyimide flex materials are suited for very high temperatures compared to FR4.
• Use in harsh environmentFlex circuits can be built with materials that are suitable to use in harsh operating environments (materials that have the following properties: waterproof, moisture proof, shock proof, high temperature oil, corrosion resistant).
