Typical Specifications of 365PCB's Flexible PCB Boards
We manufacture to IPC-6013 Class 2/3 standards with the following capabilities:
Base Materials: High-performance polyimide (PI) or polyester (PET), thickness 12–125 µm
Layer Count: 1–8+ layers, including multilayer flex and rigid-flex constructions
Minimum Trace/Space: 50 µm / 50 µm (fine-line capability)
Copper Thickness: 0.5 oz to 2 oz (rolled annealed copper recommended for dynamic flex areas)
Surface Finishes: ENIG, Immersion Tin, OSP, Selective Carbon Ink, Hard Gold
Additional Options: Coverlay, polyimide/FR4/stainless steel stiffeners, EMI shielding, impedance control, blind/buried vias, PSA adhesive, laser profiling
Design Tip: For dynamic flex zones, maintain a bend radius of at least 20× the total board thickness. In static applications, 6–10× is often sufficient. We provide free DFM review to optimize your design for yield and reliability.
Why Choose Our Flexible PCBs?
Ultra-Light & Ultra-Thin Profile — Boards as thin as 0.05 mm and up to 70% lighter than traditional rigid PCBs, perfect for portable, wearable, and space-constrained devices.
High-Density Circuitry — Minimum trace width/spacing down to 50 µm / 50 µm, enabling complex designs without increasing footprint or adding connectors.
Dynamic & Static Flexibility — Engineered to withstand repeated bending, folding, and 3D shaping. Ideal for moving parts, sliding mechanisms, or foldable products.
Proven Durability — Excellent resistance to vibration, shock, and extreme temperatures (-40°C to +150°C+). Fewer solder joints mean higher long-term reliability.
Superior Thermal Performance — Polyimide base material provides efficient heat dissipation, critical for high-power or dense components.
Excellent Solderability & Assembly Compatibility — Multiple surface finishes ensure strong, defect-free SMT assembly and long-term stability.
Compared to rigid PCBs and traditional wiring, flexible circuits can reduce overall assembly weight by over 60%, eliminate bulky connectors, and dramatically improve signal integrity in compact layouts
