Flexible printed circuit board (FPC)

Flexible printed circuit boards (FPC) from Onlitex Electronic Holding Ltd. are single-sided designs fabricated to precise dimensional tolerances, with maximum panel sizes up to 558.8mm x 711.2mm. These boards use polyimide substrates with copper foil thicknesses typically ranging from 12 to 35 microns, allowing for dynamic flexing without conductor fracture. The manufacturing process supports fine trace widths down to 75 microns and spacing of 75 microns, suitable for high-density interconnect applications in compact electronics.

The base material is standard polyimide film, which offers thermal stability up to 260°C and low moisture absorption, making it suitable for solder reflow processes. Adhesiveless laminates are used where enhanced flexibility and reliability are critical, while adhesive-based variants are available for cost-sensitive applications. Surface finishes include ENIG and HASL, both compliant with IPC-4552 standards. These boards do not include solder masks by default but can be specified with optional coverlays or solder resist layers for environmental protection.

These FPCs are sourced by manufacturers of wearable devices, automotive sensors, medical diagnostic tools, and aerospace control units where space constraints and mechanical stress require conformable circuitry. Buyers typically order in batches of 500 to 5,000 units, with packaging in anti-static trays or roll feed for automated assembly. Lead times are confirmed per order, and trade terms are negotiable under FOB or CIF terms from Guangdong ports.

Onlitex Electronic Holding Ltd. operates from a manufacturing facility in Zhangmutou, Dongguan, Guangdong, China. The supplier is listed as imported with harbor-tier trust signals, indicating verified export compliance and logistics readiness. No details are provided about company history, employee count, or annual turnover. The listing confirms production capability for FPCs but does not state certifications, client names, or in-house testing labs.

The supplier responds to inquiries with no recorded average response time, suggesting potential delays in communication. Their verified status relates to export documentation and factory address validation, not product quality certifications. Buyers should request samples and test reports directly before placing bulk orders. No claims are made about ISO, CE, or RoHS compliance in the source data, and these should not be assumed.
