QianLi QX9000 Ultrasonic Cleaner: New Arrival

Flux residue, dust, and corrosion trapped under shields are among the most common causes of callback repairs. The new QianLi QX9000 Ultrasonic Cleaning Machine — now in stock at Vexagoo — attacks that problem at the source: 35W of ultrasonic power at a 47kHz golden frequency, in a compact desktop unit built for repair benches. Here is what it does, who it is for, and how to use it correctly from day one.

What Makes the QX9000 Different

• 35W balanced power with a 47kHz frequency — strong enough for flux and residue, gentle enough for delicate boards
• Two cleaning modes: Deep uses pulsating high-frequency vibration to reach deep crevices; Regular delivers continuous gentle vibration for surface dust
• Three timer presets (60s / 180s / 360s) so you never guess how long a cycle should run
• Tempered glass lid with rounded edges — watch the cleaning happen and handle the unit safely
• Plastic-free metal and glass tank, corrosion-resistant with PCB cleaning agents and common solvents
• Smart spout design makes wastewater disposal quick and clean

Why Ultrasonic Beats Manual Cleaning

Brushes and swabs only reach what you can see. Ultrasonic cavitation generates millions of microscopic bubbles that collapse against every surface — including under shielding cans, around connector blocks, and inside component gaps that a brush physically cannot touch. For board-level repair, that means residue-free results in minutes instead of a painstaking manual session, and fewer comebacks caused by hidden contamination.

How to Use It Correctly

1. Fill the tank with water or a dedicated PCB cleaning solution — never run the unit dry
2. Place boards or parts in the tank and select Deep or Regular mode
3. Pick a timer preset: 60s for a quick rinse, 180s for standard cleaning, 360s for heavy residue
4. Let the cycle finish, rinse with clean water, and dry boards thoroughly before reassembly

For a complete cleaning-and-inspection workflow, pair the QX9000 with an anti-static brush set for pre-cleaning, then verify results under the 6558 Gorilla trinocular microscope before powering boards back on.
