Double-Sided COB FPC with OSP Finish
This flexible printed circuit (FPC) is designed for chip-on-board (COB) LED lighting modules, offering a double-sided copper layer structure with OSP surface finish for reliable soldering and extended shelf life. Built on PI material, it provides the flexibility needed for compact and curved lighting designs.
Key Selling Points
Double-Sided Circuitry
Double-sided copper structure allows more complex circuits in limited space, enabling higher LED density and better heat spreading.
OSP Surface Finish
OSP finish offers excellent solderability and flatness, ideal for fine-pitch COB assembly and reliable wire bonding.
PI Material Flexibility
Polyimide base material provides excellent thermal stability and mechanical flexibility, ensuring durability in tight or movable installations.
Industry Certifications
Manufactured under ISO 9001 and IATF 16949 quality systems, with UL recognized flammability (E498836), suitable for global use.

Models and Options
Standard model is double-sided with 1/1 oz copper, OSP finish. Custom options include single-sided layer, different copper weights, and alternate coverlay colors. Contact us for specific model configurations.
Materials and Structure
Base material is polyimide (PI) film, chosen for its thermal resistance and flexibility. Copper circuitry is etched to specification, covered with a white coverlay for insulation and light reflection. The overall thickness is 0.115mm, suitable for space-constrained lighting modules.
Applications
Primarily for lighting, especially COB LED modules used in indoor and outdoor fixtures, automotive lighting, and decorative lighting where flexibility and reliability are required.
Customization
WODE offers customization in panel size, layer count, copper thickness, and surface finish. Lead time and MOQ available upon request.
Case Study
A German lighting OEM used our COB FPC for a 5-year project, delivering 5000sqm. The product demonstrated high thermal conductivity and stable operation, meeting German safety standards and performing reliably in harsh European climate.
FAQ
Q1: What is the minimum order quantity?
Please contact us for MOQ details as it varies depending on specifications.
Q2: Can this FPC be used for high-power LED applications?
It is suitable for many lighting applications, but for very high power, thermal management must be evaluated. Please consult our engineers.
Q3: What is the typical lead time?
Lead time is typically 3-4 weeks, depending on order complexity and quantity.
Q4: Do you provide samples?
Yes, samples are available. Please contact us for sample requests.
Q5: Are these FPCs certified for international markets?
Yes, we hold UL, ISO 9001, IATF 16949, and other certifications that comply with international standards.
Q6: Can you customize the shape and circuit design?
Absolutely, we support custom designs from your Gerber files.
Q7: What is the shelf life of the OSP finish?
Generally 6-12 months under proper storage conditions.
Q8: How does this compare to single-sided COB FPC?
Double-sided offers more routing area and can increase LED density, but may be slightly thicker. The choice depends on your design requirements.
