Introduction

Cleaning
Solutions

Agents for Particle Removal

The adhesion of particles during the manufacturing of precision electronic and optical components significantly impacts product quality. Recently, immersion ultrasonic cleaning with high-performance fluorinated cleaning agents has become widely adopted for removing adhered dust from products. These agents offer several benefits:

Their low viscosity and small surface tension allow them to penetrate narrow gaps and effectively remove particles.
A higher fluid density compared to water or IPA results in a greater impact force at the same flow rate, enhancing cleaning performance.
A wide range of ultrasonic frequencies can be chosen, minimizing damage to products and enabling single-agent cleaning.

Agents for Rinse Cleaning

In the rinse cleaning process, which replaces water droplets adhered to the product surface, a method using fluorinated agents for cleaning and drying has been established to reduce drying time, improve quality, and lower equipment costs. These agents are particularly effective for cleaning parts with fine holes, narrow gaps, or those that cannot be cleaned at high temperatures. Benefits include:

Excellent quick-drying properties that allow for uniform drying, preventing water spots, improving drying yield, and shortening drying time.
Low-temperature drying, which reduces thermal impact on products compared to hot-air drying.
Low reactivity, reducing physical impact on products and allowing for the cleaning of a wide range of materials.
