Understanding Dual Interface Flexible Lead Frames

A dual interface flexible lead frame is a critical component that enables a smart card or flexible device to operate through both contact and contactless interfaces. It connects the embedded chip to external circuitry through a flexible and durable interconnect, providing versatility and reliability.

These lead frames are commonly used in:

• Banking and financial smart cards for secure payments.
• Government-issued ID cards and passports.
• Wearable electronics requiring dual connectivity.
• Healthcare smart cards and e-health records.
• IoT devices that merge wired and wireless communication.

By allowing two modes of communication, they improve usability and extend the lifetime of devices, especially in applications requiring high data security and convenience.

PLP is a cutting-edge manufacturing method that allows multiple chips to be packaged simultaneously on a large panel, significantly reducing production costs and increasing throughput.

• PLP is especially relevant for flexible lead frames, as it enables mass production of thinner, more reliable interconnects.
• This will help meet the growing demand for dual-interface smart cards and other secure devices, where cost efficiency is critical.

STMicro’s investment demonstrates a broader industry trend toward scaling production technologies to match rising demand.

3. LG Innotek Introduces Copper Post Interconnect Technology

In 2025, LG Innotek revealed a new copper post technology that replaces traditional solder balls in semiconductor packaging.

• This approach allows for 20% smaller pitch spacing, higher thermal conductivity, and reduced device thickness.
• For dual interface flexible lead frames, it enables denser circuitry and better performance, particularly for applications like biometric ID cards or advanced wearables.

This innovation represents a step forward in meeting the miniaturization needs of modern devices while maintaining durability and electrical performance.

4. Marvell’s Advanced Packaging Platform for AI Devices

While primarily focused on AI accelerators, Marvell Technology introduced an advanced packaging platform that supports multi-chiplet integration.

• This technology allows for more efficient interconnects and flexible packaging designs.
• The implications for the dual interface lead frame market include cross-application integration, where smart cards or IoT devices incorporate AI-based security features.

This reflects a trend toward heterogeneous integration, where multiple chip types coexist in a single package, pushing the boundaries of flexible lead frame designs.

5. Growth of Automated FOWLP Design Tools

Recent publications, such as those in EDN Magazine, highlight the growing use of automation in Fan-Out Wafer-Level Packaging (FOWLP) design.

• Automation helps reduce design complexity and improve yield and reliability, both critical for dual interface products.
• It also shortens time-to-market for new products, allowing manufacturers to keep pace with evolving security standards.

The rise of FOWLP tools indicates a broader shift toward smart manufacturing in the lead frame industry.
