2UUL BB Nano (DA90) - 30W Precision Mini Fan

Technical Description

The 2UUL BB Nano (DA90) is an essential precision tool for any micro-electronics workshop. Delivering 30W of power, this mini fan produces a surprisingly strong blast of air for its size. It has been specifically designed to meet two critical needs: the immediate cooling of integrated circuits (CPU, NAND, GPU) after soldering, and the forced-air cleaning of optical surfaces or housings before reassembly.

Its high-performance turbine reaches very high rotation speeds, providing a precise, laminar airflow. Unlike traditional compressed air solutions, the BB Nano is eco-friendly, rechargeable via USB-C, and does not spray any moisture onto sensitive components. Its lightweight alloy structure and ergonomic design allow for easy handling under a microscope or in the cramped areas of a smartphone.

Key Benefits

• Exceptional Blowing Power: Instantly removes dust, glass debris, and solder residue without physical contact.
• Turbo Cooling: Reduces waiting time between soldering steps by lowering the PCB temperature in just a few seconds.
• Cost-Effective Alternative: Permanently replaces the need for disposable compressed air cans, offering a cost-effective long-term investment.
• Flow Precision: The integrated nozzle allows air to be directed precisely onto an area without displacing surrounding small components.
• Battery Life and Mobility: Cordless and compact, it fits in a pocket and remains ready for use at any workstation.

Workshop Tip: Use the BB Nano just before applying a touch screen or tempered glass to clear away the last particles of dust. For cooling, use gentle sweeping motions over the freshly soldered chip to avoid excessive thermal shock while quickly setting the solder.
