Our flex and rigid-flex products offer cost-effective solutions ranging from single or double-sided circuitry to multilayer designs up to 20 layers. We assist in selecting optimal configurations, connectors, and components to meet your application requirements.

These PCBs are designed for medical, military, aerospace, and portable device applications. Our engineering team provides support from initial design through production for all flex and rigid-flex circuit needs.

Reliable flex PCB design requires attention to key factors:

• Bend Radius: Minimum radii down to 0.1mm achievable with optimal materials
• Board Stiffness: Polyimide films with selective stiffening elements
• Thermal Management: Copper planes with thermal relief techniques
• High-Frequency Layout: Controlled impedance traces and ground planes
• Component Selection: Low-profile SMT components preferred
• Attachment Methods: Soldering, conductive epoxy, or mechanical fastening

Our engineering team provides design reviews to optimize manufacturability and performance.

Specialized assembly processes ensure reliable component mounting:

• SMT assembly for lower component counts
• Manual assembly for high densities
• Multiple attachment methods including solder joints and conductive epoxy
• Specialized rework processes for sensitive polyimide films

Our advanced fabrication techniques produce high-quality flex circuits:

• Polyimide base materials for heat resistance and flexibility
• Rolled annealed copper laminated circuits
• Multilayer constructions with 2-12 metal layers
• Microvias with diameters down to 50μm
• Comprehensive quality testing throughout production
