48-UFQFN
48-UFQFN
The 48-UFQFN (48-pin Ultra Thin Fine Pitch Quad Flat No-lead) is a surface-mount package designed for high-density circuits. Featuring leadless design, exposed thermal pad, and ultra-thin profile of 0.5mm height, it delivers superior heat dissipation and reduced signal interference with compact size. Typical dimensions are 6×6 mm with a 0.5 mm pin pitch, making it ideal for power management ICs in portable devices, RF modules, and IoT applications. 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 48-UFQFN?
A:Key features include:
- Leadless bottom-mounted pads for compact PCB attachment.
- Central thermal pad (80% coverage) for enhanced heat dissipation.
- 48-pin layout with peripheral array for optimized signal routing.
- 0.5 mm ultra-thin profile for space-constrained designs. -
Q:Why choose 48-UFQFN over alternatives?
A:Critical advantages:
- Miniaturization: 60% smaller than equivalent QFP packages.
- Thermal Performance: Direct PCB heat path via exposed thermal pad.
- Electrical Benefits: Low-inductance design for high-frequency applications.
- Reliability: Moisture-resistant substrate (MSL3 rated). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 6×6 mm
- Height: 0.5 mm
- Pin Pitch: 0.35 mm
- Material: Copper-alloy leads with Ni/Pd/Au plating.
- Temp Range: -40°C to +125°C. -
Q:Where is 48-UFQFN typically applied?
A:Dominant use cases:
- Power Converters: e.g., Buck/boost ICs (e.g., TPS62130).
- RF Modules: e.g., Bluetooth/Wi-Fi SoCs (e.g., CC2652R).
- Sensor Interfaces: e.g., MEMS accelerometers (e.g., LSM6DSO). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: Thermal vias under pad (≥4 vias, 0.3mm diameter).
- Solder Paste: Type 4 solder recommended for fine-pitch printing.
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for void detection.
