The "Printed Circuit Board (PCB)" can be considered the heart of electronic devices; it serves as a foundation for mounting electronic components and electrically connecting them. The fine wiring patterns formed on this board become pathways for electronic signals, and the electronic components are fixed and connected by solder. From smartphones to automobiles, home appliances, and medical devices, PCBs have become an indispensable part of various technologies in modern society. In this article, we will introduce the main types of printed circuit boards (PCBs), the future prospects seen from the development of these boards, and the cleaning technologies that are required. Please see the related links for more information.

An SDS (Safety Data Sheet) is a document that contains important information regarding the handling of chemical substances, relevant regulations, disposal and transportation methods, as well as hazards and toxicity. The applicable regulations for flux cleaning agents, the presence or absence of flash points, usage precautions, the necessity of protective equipment, and disposal methods are detailed over more than 10 pages. In this article, we will explain important points that we particularly want you to pay attention to, as well as frequently asked questions, in a column format. Please see the related links for more information.

This is the updated version (ver.2) of the popular document "Fundamentals of Flux Cleaning." In this revision, in addition to the existing content (how to choose cleaning agents and cleaning methods), we have added the basics of "Residue Evaluation (Analysis)." This document is recommended for those who are just starting with flux cleaning and for those who want to understand the entire process from cleaning to analysis. In addition to the purpose of cleaning and the fields where cleaning is necessary, we also explain the necessity and methods of chemical analysis, so please take a moment to read it.
