OEM ODM PCBA Cold Lamination Processing

PCBA Cold Lamination is a proprietary, low-temperature encapsulation technology developed by prosmartcard (Union Smart). Conventional hot lamination involves high heat and intense hydraulic pressure that frequently degrades sensitive microelectronics, lithium batteries, and display components. Our advanced cold lamination methodology safely integrates flexible PCBAs, ultra-thin batteries, Bluetooth modules, E-paper displays, and biometric sensors into ultra-thin, standard credit-card-thickness (<2.0 mm) smart cards.

Key Technical Advantages

• Zero High-Temperature Thermal Stress: Operates under low temperatures to preserve fragile lithium battery cells, organic E-ink display layers, and sensitive microcontrollers without thermal degradation.
• Ultra-Thin Form Factor (<2.0 mm): Achieves ISO standard credit-card dimensions (85.5 × 54 mm) or custom profiles that fit effortlessly into personal wallets, pockets, and cardholders.
• Flexible Component Integration: Supports multi-layer flexible PCBAs (FPC), surface-mount devices (SMD), LEDs, buzzers, tactile push buttons, and wireless recharging coils.
• Zero Tooling & Mold Costs: No requirement for expensive injection tooling or high-cost custom steel molds, significantly reducing prototyping capital and shortening NPI (New Product Introduction) cycles.
• Rapid Prototyping to Mass Production: Fast turnaround from CAD engineering validation to functional working samples in days, followed by scalable mass production in our cleanroom facilities.
• Durable & Moisture-Resistant: Sealed encapsulation provides structural protection, IP-grade moisture resistance, and mechanical resilience against bending and daily tapping.
