【Japanese Only / No English Subtitles】PlasmaTalk × Dr. Kosuke Haraga, Adhesion Technology Consultant: The Importance of Cohesive Failure in Achieving High-Reliability, High-Quality Adhesion

Important Notice
This webinar will be conducted in Japanese only. English subtitles and interpretation will not be available.

Achieving stable, high-strength, and durable adhesion is a major challenge in many applications, and surface treatment technology is one of the key solutions.

Atmospheric-pressure plasma treatment is a surface modification method that can improve adhesion reliability without the use of solvents. Plasmatreat’s atmospheric-pressure plasma technology, Openair-Plasma^®, has undergone continuous technological advancement and has been widely adopted across many industries worldwide. In recent years, as demand has grown and technologies have advanced rapidly, especially in electronics and semiconductor manufacturing, this technology has increasingly been used for applications such as underfill pretreatment and resin encapsulation pretreatment for power modules to help prevent delamination.

In this webinar, we are pleased to welcome Dr. Kosuke Haraga, Chief Consultant at Haraga Adhesion Technology Consulting Co., Ltd., who has extensive knowledge and experience in high-quality, high-reliability adhesion technology.

Presentation by Dr. Haraga

Title: The Importance of Cohesive Failure in Achieving High-Reliability, High-Quality Adhesion

Presentation Overview:
No matter how excellent adhesion strength and durability may be, these alone do not guarantee high-reliability, high-quality adhesion. It is also necessary to achieve low variability in adhesion performance, low defect rates, and favorable productivity and cost performance.

To satisfy these requirements, the basic approach is to reduce interfacial failure and increase the rate of cohesive failure. Surface modification is an essential technology for improving the cohesive failure rate.

In this presentation, Dr. Haraga will explain why improving the cohesive failure rate is important and how it can be achieved, from the perspectives of variability in adhesion strength, the onset strength of internal failure, fatigue characteristics, and the initial strength margin required against forces applied to bonded parts.

Topics

• High-reliability, high-quality adhesion requirements
• Variability in fracture strength
• Onset strength of internal failure
• Fatigue characteristics
• Why increasing the cohesive failure rate is important and how it can be achieved

If you have any questions for Dr. Haraga, please enter them in the Questions & Comments field on the Zoom registration page. We will address selected questions during the webinar.

Please note, however, that if we receive a large number of questions, we may not be able to answer all of them. In addition, depending on how close your registration is to the webinar date, or depending on the content of your question, we may refrain from responding.
