Modern electronic devices are highly advanced, and even minor malfunctions can lead to significant incidents. Events that undermine insulation threaten the reliability of products, and one phenomenon that can contribute to this is ion migration, which has been considered a past issue. It has been said that this has been overcome due to the evolution of various insulating materials such as coatings and resists, as well as advancements in cleaning-free technologies. However, as the miniaturization and high density of electronic substrates rapidly progress, ensuring insulation has become increasingly difficult, and the risk of ion migration is once again on the rise. This article will explain why ion migration has become a trend again, exploring its mechanisms, specific countermeasures, and evaluation methods to assess the potential for its occurrence.

"Before the resin encapsulation of semiconductors." We have added a page to the technical document titled "Why Did the 'Silent Evolution' Occur?" The article provides a detailed explanation of the basic concepts of semiconductor resin encapsulation, as well as specific approaches to surface treatment that are key to maximizing quality. Additionally, the technical document systematically organizes the mechanisms behind the deterioration of insulation and the instability of resin bonding strength, and explains advanced insights into surface design and cleaning technologies that are essential for high-reliability devices. We encourage you to read it.

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.
