49-UFBGA, WLCSP
The 49-UFBGA (Ultra Fine Pitch Ball Grid Array) and WLCSP (Wafer-Level Chip Scale Package) are surface-mount packages designed for high-density circuits in compact electronic devices. Featuring an ultra-fine pitch ball grid array, wafer-level chip scale design, and a low-profile form factor, they deliver superior space saving and enhanced thermal management. Typical dimensions are 3×3 mm with a 0.4 mm pin pitch and a height of 0.6 mm, making them ideal for mobile devices, IoT sensors, and wearable electronics. Their bottom-terminal ball contacts enable direct PCB thermal transfer, while RoHS-compliant materials ensure reliability in industrial environments.

Q:What defines the physical structure of 49-UFBGA (WLCSP)?
A:Key features include:
- Leadless bottom-mounted pads: Direct solder attachment to PCB.
- Central thermal pad: ~30% coverage for enhanced heat dissipation.
- 49-pin layout: Area-array configuration (7×7 matrix).
- Ultra-thin profile: 0.5 mm height for space-constrained designs. -
Q:Why choose 49-UFBGA (WLCSP) over alternatives?
A:Critical advantages:
- Miniaturization: 40% smaller footprint than equivalent QFN packages.
- Thermal Performance: Direct PCB heat path via thermal pad.
- Electrical Benefits: Low-inductance design (<0.5 nH) for high-frequency signals.
- Reliability: Moisture-resistant substrate (MSL3 rating). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 3.5 × 3.5 mm.
- Height: 0.5 mm.
- Pin Pitch: 0.4 mm.
- Material: Copper-alloy pads with Ni/Au finish.
- Temp Range: -40°C to +125°C (industrial grade). -
Q:Where is 49-UFBGA (WLCSP) typically applied?
A:Dominant use cases:
- Mobile Devices: PMICs (e.g., TPS65988).
- IoT Modules: Bluetooth/Wi-Fi SoCs (e.g., ESP32 series).
- Embedded Systems: MEMS sensors (e.g., BNO055 IMU). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: 4×4 thermal via array under central pad (0.2 mm diameter).
- Solder Paste: Type 4 (5–15 µm particle size) for fine-pitch printing.
- Reflow Profile: Peak temp ≤ 245°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for void detection (<15% tolerance).
