QFN-16
QFN-16
The QFN-16 (Quad Flat No-leads-16) 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, reduced signal interference, and space-saving benefits. Typical dimensions are 4×4 mm with a 0.5 mm pin pitch and 0.9 mm height, making it ideal for power management ICs, RF modules, and portable electronics. 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 QFN-16?
A:Key features include:
- Leadless bottom-mounted pads: Ensures direct PCB connectivity without protruding leads.
- Central thermal pad: 4×4 mm coverage (typical) for enhanced heat dissipation.
- 16-pin layout: Quad-flat arrangement with perimeter pads.
- Ultra-thin profile: 0.9 mm height for space-constrained designs. -
Q:Why choose QFN-16 over alternatives?
A:Critical advantages:
- Miniaturization: 40% smaller footprint than equivalent SOIC-16 packages.
- Thermal Performance: Direct PCB heat path via the central thermal pad.
- Electrical Benefits: Low-inductance design (<0.5 nH) for high-frequency applications.
- Reliability: Moisture-resistant substrate (MSL3 rating). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 4×4 mm (varies by vendor).
- Height: 0.9 mm (nominal).
- Pin Pitch: 0.5 mm.
- Material: Copper-alloy leads with matte Sn plating.
- Temp Range: -40°C to +125°C (industrial grade). -
Q:Where is QFN-16 typically applied?
A:Dominant use cases:
- Power Converters: e.g., DC-DC buck regulators (TPS62130).
- RF Modules: e.g., Bluetooth/Wi-Fi transceivers (NRF51822).
- Sensor Interfaces: e.g., MEMS accelerometers (ADXL345). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: 4×4 via array under the thermal pad (0.3 mm diameter recommended).
- Solder Paste: Type 4 (fine powder) for reliable pad wetting.
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory due to hidden solder joints.
