Metal / screen mask cleaner, HA series

Introduction

KAKEN TECH has been developing cleaning agents for the electrical and electronics industries for many years, and has recognized many solder pastes, thick film pastes and inks, and component fixing bonds (commonly known as red bonds).
As a specialized manufacturer of cleaning agents, we develop cleaning agents from a variety of perspectives, including the following;

  • ■R&D of cleaning agent for various pastes, adhesives and bonds,
  • ■R&D for products that do not fall under various laws and regulations or have low odor,
  • ■Cleaning agent design with consideration of component resistance

Use in combination with a cleaning device is effective for improving cleanability!

We verified the cleaning of metal masks used for printing solder paste; please take a look at the effects of wiping by hand with IPA, using a cleaning spray, and using an automatic machine.

Recently, electronic substrates and components are becoming more and more precision structured year by year. As a result, the apertures of screen stencil have become micron-sized, and manual cleaning often results in poor cleaning due to residues remaining on the stencil. For this reason, many companies have proposed automatic cleaning machines using ultrasonic waves or showers. KAKEN TECH's cleaning agents are recommended for SAWA CLEAN, a stencil cleaning system series manufactured by SAWA CORPORATION. SAWA CLEAN is a cleaning system that irradiates ultrasonic waves directly onto metal masks and screen masks to clean even the smallest residues, eliminating the problems caused by immersion ultrasonic waves and shower cleaning.
