Flux residues require the selection of analytical methods based on their type. By conducting chemical analysis, it is possible to analyze the causes of defects and improve processes. You can download a free document summarizing our analysis service overview. If you are struggling with cleaning processes or defect analysis, please take a look. Zestron offers cleanliness analysis technology that can comply with ISO 9455-18:2024.

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.

What is substrate cleaning? Is substrate cleaning unnecessary? We provide a detailed explanation of areas where flux cleaning is necessary, among other topics. In Japan, many cases adopt no-clean paste, but cleaning has become essential to ensure high reliability. We also address the latest cleaning challenges, such as the impact of ionic residues and metal salts on insulation resistance, in this column. Recommended for those who: * Want to investigate the causes of defects despite cleaning * Want to know the latest cleaning challenges and evaluation criteria * Want to explain and promote substrate cleaning within their company, etc. Please see the related links for more information.
