E-Cigarette PCBs with ENIG (Electroless Nickel Immersion Gold) surface finish represent a crucial component in modern vaping devices, combining compact design with high-performance electronics.
Key features include:
- ENIG surface providing excellent solderability and extended shelf life
- Enhanced durability for frequent handling and battery changes
- Excellent electrical conductivity for efficient power delivery
- Compatibility with fine-pitch components in compact designs
- Corrosion resistance for longevity in varying environmental conditions
The ENIG finish offers a flat, uniform surface ideal for the small, densely packed components typical in e-cigarette circuitry. It ensures reliable connections for critical functions like temperature control, power regulation, and user interface elements.
These PCBs are designed to withstand the unique challenges of e-cigarette use, including exposure to heat, e-liquid residue, and frequent charging cycles. They often incorporate advanced features such as short-circuit protection, overcurrent protection, and precise wattage control.
While more expensive than simpler finishes, ENIG-surfaced PCBs offer superior reliability and performance crucial for safe and consistent e-cigarette operation, making them a preferred choice for high-quality vaping devices.
