24-QFN
24-QFN
The 24-QFN (Quad Flat No-lead) 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 0.5 mm pin pitch and a height of 0.9 mm, making it ideal for power management ICs in portable devices, RF modules, and IoT sensors. 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 24-QFN?
A:Key features include:
- Leadless bottom-mounted pads for compact PCB attachment.
- Central thermal pad (80% coverage) for enhanced heat dissipation.
- 24-pin layout with peripheral arrangement for balanced signal distribution.
- 0.9 mm ultra-thin profile for space-constrained designs. -
Q:Why choose 24-QFN over alternatives?
A:Critical advantages:
- Miniaturization: 40% smaller than SOIC-24.
- Thermal Performance: Direct PCB heat path via exposed thermal pad.
- Electrical Benefits: Low-inductance design (<0.5 nH) for high-frequency stability.
- Reliability: Moisture-resistant substrate (MSL3 rating). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 4×4 mm.
- Height: 0.9 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 24-QFN typically applied?
A:Dominant use cases:
- Power Converters: e.g., Buck/boost ICs (e.g., TPS62130).
- RF Modules: e.g., Bluetooth/Wi-Fi transceivers (e.g., CC2541).
- Sensor Interfaces: e.g., MEMS accelerometers (e.g., LIS2DH12). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: Thermal vias (4×4 array) under the central pad.
- Solder Paste: Type 4 solder recommended for fine-pitch reliability.
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for void detection.
