High airtightness / low moisture permeability sealant – The voices of developers

Requirements for high airtightness / low moisture permeability sealant

世界有数のシェアを持つ強み

Absolute advantage based on our leading market share

We have a leading market share in the world in high airtightness / low moisture permeability sealants used for sealing the lit glasses of Image sensor packages, and we have ample technical knowledge and know-how.

However, our technical potential is not improved only by making use of our past achievements.

We are supporting our clients while repeatedly revising our product improvement policies by making proposals about products to be developed, evaluating them, and identifying issues through our technologies and products.

For example, we once faced a problem of delamination of sealing parts while conducting a high-temperature test at the initial development stage. To identify the cause of the problem, we made an evaluation, and finally successfully solved it by optimizing the raw material ratio. We are always trying to efficiently develop products by finding the best sample composition and repeating the evaluation and analysis processes, instead of blindly repeating experiments.

Ideal framework based on joint evaluation with our clients

One of the factors which allowed our products to gain a leading market share was the successful establishment of a system for joint evaluation with our clients. Any remedial measures can be immediately identified by evaluating the material actually used by them, which enables us to see the next step for improvement.

In this technology, our success in building an extremely close relationship with our clients, that is, the joint evaluation system was the major contributing factor in its establishment. Not only by accepting requests from our clients, but also by proactively making proposals, and jointly evaluating and examining them, we succeeded in developing an extremely high-quality technology and commercializing the products.

10年以上にわたる実績と知見

Achievements and knowledge over the past 10 years

Ever since the technology of high airtightness / low moisture permeability sealant was established, development has proceeded based on requests from our clients.

One of the cases where we made use of our knowledge and experience is that once we proposed a prototype for which no abnormality was detected in sealing parts by internal evaluation using the environment test equipment in advance. However, the client could not duplicate our results. We asked for a test piece for analysis, and we found out that the cause of the defect was likely to be due to the process. We thus had a meeting with the client, and offered our knowledge and know-how to solve the problem. As a result, the problem was successfully solved, and the mass production has been going on smoothly.

We are striving to develop and offer new sealants by constantly searching for “the best structure”, avoiding excessive reliance on our past achievements while making use of our knowledge and experience accumulated over the past years.

Our goal is to continuously offer highly reliable technologies.

Our products are recognized as the most reliable resin.

We have a variety of analysis equipment with excellent capabilities, and facilities for readily conducting evaluations in accordance with the customers’ mass production process. The ability to swiftly apply the analysis and evaluation results to the development process by using these facilities is our major advantage, and allows us to gain the strong confidence of our customers.

By making full use of such a development environment, and our achievements and knowledge, we are determined to continuously engage in development activities to offer highly reliable technologies and products.
