Import Flexible Pcb, Have Single-Sided, Double-Sided, M — Buy in Bulk from Supplier in China

The product is a flexible printed circuit board (PCB) offered in single‑sided, double‑sided and multi‑layer formats. Each board is built on a four‑layer base film that incorporates 1 oz copper layers and a 1 mil polyimide (PI) substrate for thermal stability. A 1 mil PI coverlay with adhesive protects the circuitry, while a 1 mm steel stiffener adds structural support without sacrificing flexibility. Surface finishes are supplied as either immersion gold or electroless nickel immersion gold (ENIG), providing reliable solderability.

The use of 1 oz copper and polyimide aligns with industry standards for high‑frequency and high‑temperature applications, where dielectric loss and dimensional stability are critical. Typical flexible PCBs in the market employ copper thicknesses from 0.5 oz to 2 oz and substrate thicknesses between 0.5 mil and 2 mil; the listed 1 mil PI is within the standard range for consumer electronics. Standard mechanical reinforcement includes steel or FR‑4 stiffeners, with 1 mm being a common dimension for maintaining bend radius. Finishing options such as immersion gold and ENIG are recognised for their corrosion resistance and compatibility with lead‑free solder processes.

These PCBs are suited to devices like smartphones, wearable health monitors and automotive telematics units, where space constraints demand thin, bendable interconnects. Importers typically request FOB or CIF terms and settle payments via L/C or T/T, matching the supplier’s stated trade options. Potential buyers should confirm the minimum order quantity, exact lead time and any required certifications, as the supplier notes a flexible MOQ policy but does not disclose specific figures.
