DFN-14
DFN-14
The DFN-14 (Dual Flat No-lead 14-pin) is a surface-mount package designed for high-density circuits. Featuring leadless design, exposed thermal pad, and ultra-thin profile, it delivers superior heat dissipation and reduced signal interference. Typical dimensions are 4×4 mm with a 0.65 mm pin pitch and height of 0.8 mm, making it ideal for power management ICs in portable devices, consumer electronics, and RF modules. Its bottom-terminal contacts enable direct PCB thermal transfer, while RoHS-compliant materials ensure reliability in industrial environments.

Q:What defines the physical structure of DFN-14?
A:Key features include:
- Leadless bottom-mounted pads for direct PCB attachment.
- Central thermal pad (70% coverage) for enhanced heat dissipation.
- 14-pin layout with dual-row perimeter arrangement.
- 0.8 mm ultra-thin profile for space-constrained designs. -
Q:Why choose DFN-14 over alternatives?
A:Critical advantages:
- Miniaturization: 40% smaller than SOIC-14.
- Thermal Performance: Direct PCB heat path via exposed pad.
- Electrical Benefits: Low-inductance design (<0.5 nH) for high-frequency apps.
- Reliability: Moisture-resistant (MSL3) substrate. -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 3.0×3.0 mm.
- Height: 0.8 mm.
- Pin Pitch: 0.5 mm.
- Material: Copper-alloy leads with Ni/Pd/Au plating.
- Temp Range: -40°C to +125°C. -
Q:Where is DFN-14 typically applied?
A:Dominant use cases:
- Power Converters: e.g., Buck regulators (TPS62130).
- RF Modules: e.g., Bluetooth/Wi-Fi transceivers (NRF52840).
- Sensor Interfaces: e.g., MEMS accelerometers (LIS2DH). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: Thermal vias (4×4 array) under central pad.
- Solder Paste: Type 4 (20–38 µm particle size).
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for pad alignment.
