PCB and Electronics Cleaning, Ultrasonic
Flux residues, dust films and corrosion products are slow failures: leakage paths, RF detuning, connector resistance rising until something drops out at 2am. Cleaning them off assemblies without damaging components is a parameter problem, not a courage problem.
Misonics systems clean PCB assemblies, connectors and telecom hardware with electronics-appropriate frequency, power and chemistry — proven on sacrificial boards before production ever runs.
What we remove in electronics & telecoms
Flux residues
Rosin and no-clean residues that trap moisture and create leakage paths.
Dust & particulate films
Conductive contamination across boards and RF hardware.
Corrosion products
On connectors and contacts in humid and coastal service.
Conformal coating prep
Residues that undermine coating adhesion.
Oxides on contacts
Rising resistance in connector systems.
Real parts, real materials
PCB assemblies
Post-solder flux removal and pre-coating cleanliness — at frequencies and powers proven safe for the assembly.
Connectors & RF
Connector bodies, waveguide components, antenna hardware — restored contact and RF performance.
Field-return refurbishment
Radio units, enclosures hardware and site-recovered equipment brought back to service standard.
Cavitation cleans geometry it cannot see
Bubble collapse at the liquid–metal boundary lifts contamination from passages, galleries and cavities without anything touching the surface. Nothing abrades, nothing embeds, no metal is removed.
The VarioSonic G4 tracks the transducer array as temperature and load shift — conversion efficiency up to 95%.
Eliminates standing-wave hot and cold zones across a loaded basket.
Stored recipes and logged cycles — audit evidence produced as a by-product of running.
Multi-stage filtration and weir oil capture hold results steady as the bath loads.
Most faults identified — many resolved — without a site visit.
Heavy 316 stainless tanks, tested before despatch, every wearing part replaceable.
The machine follows the process
From manually loaded single-tank units to automated lines — and engineered systems where the catalogue ends.
Matched to the soil and the substrate
Electronics cleaning runs higher frequencies, controlled power and low-residue chemistry with clean rinsing and drying — the parameter set is proven on sacrificial assemblies first.
