LQFP-44
LQFP-44
The LQFP-44 (Low-profile Quad Flat Package - 44 pins) is a surface-mount package designed for high-density integrated circuits. Featuring a low profile height, compact footprint, and gull-wing leads, it delivers significant space savings on the PCB and enables compact device designs. Typical dimensions are 10×10 mm with a 0.8 mm pin pitch and a typical height of 1.4 mm, making it ideal for microcontrollers, digital signal processors (DSPs), and communication chips. Its exposed die pad enables direct PCB thermal transfer, while RoHS-compliant materials ensure reliability in industrial and consumer electronics environments.

Q:What defines the physical structure of LQFP-44?
A:Key features include:
- Leaded design: Gull-wing leads for reliable PCB mounting.
- Central thermal pad: Optional 4×4 mm pad for enhanced heat dissipation.
- 44-pin layout: Quadruple-row arrangement (11 pins per side).
- Low profile: 1.4 mm typical package height. -
Q:Why choose LQFP-44 over alternatives?
A:Critical advantages:
- Space efficiency: 30% smaller footprint than standard QFP packages.
- Thermal Performance: Exposed die pad improves heat transfer to PCB.
- Electrical Benefits: Low-inductance leads for high-frequency stability.
- Reliability: Molded plastic body with moisture sensitivity level (MSL3). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 10×10 mm (±0.2 mm tolerance).
- Height: 1.4 mm (max).
- Pin Pitch: 0.8 mm lead spacing.
- Material: Copper-alloy leads with matte tin plating.
- Temp Range: -40°C to +125°C (industrial grade). -
Q:Where is LQFP-44 typically applied?
A:Dominant use cases:
- Microcontrollers: STM32F4 series, NXP LPC family.
- Communication ICs: Bluetooth/Wi-Fi modules (e.g., ESP32).
- Industrial Control: Motor drivers and PLC interfaces. -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: Thermal vias under the central pad (if present).
- Solder Paste: Type 3 or 4 for fine-pitch leads.
- Reflow Profile: Peak temperature ≤ 250°C (SnAgCu solder).
- Inspection: AOI (Automated Optical Inspection) for lead alignment.
