364-LFBGA

Q:What defines the physical structure of 364-LFBGA?

A:Key features include:
- Leadless bottom-mounted pads for compact PCB attachment.
- Central thermal pad (70% coverage) for enhanced heat dissipation.
- 364-pin layout with a staggered grid array arrangement.
- 1.2 mm ultra-thin profile for space-constrained designs.

Q:Why choose 364-LFBGA over alternatives?

A:Critical advantages:
- Miniaturization: 40% smaller footprint than comparable QFP packages.
- Thermal Performance: Direct PCB heat path via thermal pad reduces junction temperature by 15°C.
- Electrical Benefits: Low-inductance design (<0.5 nH) for high-speed signals.
- Reliability: Moisture-resistant substrate (MSL3 rated) for harsh environments.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 15×15 mm.
- Height: 1.2 mm.
- Pin Pitch: 0.8 mm.
- Material: Copper-alloy leads with Ni/Pd/Au finish.
- Temp Range: -40°C to +125°C (industrial grade).

Q:Where is 364-LFBGA typically applied?

A:Dominant use cases:
- Power Converters: High-current ICs (e.g., TI TPS65988).
- RF Modules: 5G/Wi-Fi 6 transceivers (e.g., Qualcomm QCN9074).
- Sensor Interfaces: MEMS arrays (e.g., Bosch BMI323).

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: 4×4 thermal via array under the central pad (0.3 mm diameter).
- Solder Paste: Type 4 solder (particle size 20–38 µm) for fine-pitch printing.
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for void detection (<15% tolerance).
