Why Ultrasonic Cleaning for Electronics and PCB
Electronics cleaning requires controlled energy and compatible chemistry to remove flux residues, ionic films, and particulates without damaging delicate components. Ultrasonic cavitation provides uniform cleaning action that reaches under components and into tight features where brushing can leave residues behind.
With the right frequency, temperature control, and process safeguards, ultrasonic cleaning supports repeatable results for assembly, rework, and production workflows.
- Reaches tight geometries and under-component areas more consistently
- Supports repeatable cleaning results across batches
- Environmentally friendly
Recommended Baskets
Note: Baskets are sold separately and should be sized to match your tank.
Recommended Cleaning Solutions
Dilute Elma tec clean A1 to 3-10% for flux residues, solder paste, and light oils. Use Elma clean 260 where a neutral, low-residue cleaner is preferred.

Frequently Asked Questions
Yes, ultrasonic cleaning is effective for removing flux, residues, and contaminants from printed circuit boards. Always measure your largest board to ensure that it fits in the tank and basket selected.
When using the correct frequency and compatible solutions, ultrasonic cleaning is safe for most electronic assemblies.
Use a mild ultrasonic cleaning solution that will leave no residue after rinsing, such as Elma tec clean A1. Never put a flammable solvent, such as IPA, directly in the tank unless it has an explosion-proof rating.
