200

Q:What defines the physical structure of 200-pin BGA?

A:Key features include:
- Leadless bottom-mounted pads: Solder balls replace traditional leads for compactness.
- Central thermal pad: 10×10 mm coverage (80% area) for enhanced heat dissipation.
- 200-pin layout: Symmetrical grid array (14×14 matrix with 4 corner voids).
- Ultra-thin profile: 1.2 mm overall height.

Q:Why choose 200-pin BGA over alternatives?

A:Critical advantages:
- Miniaturization: 40% smaller footprint than equivalent QFP packages.
- Thermal Performance: Direct PCB heat path via thermal balls + central pad.
- Electrical Benefits: Low-inductance (<0.5 nH) due to short ball interconnects.
- Reliability: Moisture-resistant FR-4 substrate (MSL 3 certified).

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 15×15 mm.
- Height: 1.2 mm (including solder balls).
- Ball Pitch: 0.8 mm.
- Material: SAC305 solder balls, copper-alloy substrate.
- Temp Range: -40°C to +125°C (industrial grade).

Q:Where is 200-pin BGA typically applied?

A:Dominant use cases:
- Networking: High-speed switches (e.g., Broadcom BCM56960).
- Automotive: ECU modules (e.g., NXP S32G2).
- Consumer: GPU peripherals (e.g., NVIDIA Tegra).

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: 4:1 via aspect ratio under thermal pad; 6-layer stackup minimum.
- Solder Paste: Type 4 (20–38 µm particle size) with 80% stencil aperture.
- Reflow Profile: Ramp rate ≤2°C/s; peak temp 235–245°C (Pb-free).
- Inspection: AXI (Automated X-ray) mandatory for void detection (<15% tolerance).
