	High solubility Flux residue stuck into small parts can be removed strongly.
	Improve work efficiency WS-923U has higher flux solubility and dries faster than IPA, which improves work efficiency.
	Good for environment WS-923U does not contain chlorofluorocarbons or ethane.
	Good part durability WS-923U is designed in consideration of the solvent resistance of the parts to be mounted.

	Trouble solution "Cleaning" in Electronics industory Cleaning related to the mounting process is explained using the example of the double-sided mounting process, in which inserted components are mounted (flow process) after surface mounting (reflow process) .
	PCB Mounting Columns What is flux, the leading actor of soldering ? In addition to what flux is, its role, composition, and types, we will also explain the problems caused by flux residue left after soldering and how to prevent them.
	Trouble solution Tips on flux cleaning Flux cleaning is a process to remove flux residue that is generated at the same time as soldering when mounting electronic components. This page explains why flux is cleaned, what cleaning methods are available, and what is required for efficient cleaning.
