Precision cleaning

High-frequency ultrasonic cleaning for electronic and optical components

For electronic and optical parts with demanding surfaces, fine structures or small features.

Updated2026-08-07Reviewed againstSunnytec high-frequency cleaning product dataUse boundaryPreliminary selection; production requires engineering confirmation
01

Define unacceptable risks first

Describe coatings, polished surfaces, fragile features, feature sizes and acceptable appearance changes rather than pursuing cleaning intensity alone.

02

Frequency and process window

STC-4SS-3868, the 100/160 kHz dual-frequency model and the 200 kHz model provide preliminary comparison points; sample testing confirms the final process.

03

Make cleanliness measurable

Define measurable particle, residue, appearance or other acceptance criteria before the project rather than relying on visual judgment alone.

TECHNICAL FAQ

Common customer questions

Can high frequency damage parts?＋

Every frequency requires power, time, medium and part testing; frequency alone cannot guarantee safety.

Can coated parts be cleaned?＋

Coating data and sample validation are required, especially adhesion and acceptable surface change.
