We will be exhibiting at the Thermal Tech 2026 event held on April 24, 2026.

It is a heat-resistant laminated board that integrates polyimide film without adhesive.

Kawamura Industries' "Polyimide Laminate (PI-Plate)" is a laminate made by layering and thermally bonding polyimide film that has been activated on its surface through plasma treatment. **Features of Kawamura Industries' "Polyimide Laminate"** - Excellent heat resistance due to being adhesive-free → Continuous: 200°C / Short-term: 400°C - Exhibits excellent mechanical properties derived from polyimide film - Laminates can be produced in sizes up to 480mm x 1,100mm - Maximum thickness of 10mm (proven) *Please feel free to consult us regarding thicknesses over 10mm. *For examples of properties, please refer to the PDF document or feel free to contact us.

The "vacuum hot press," which can also perform surface treatment in the previous process, and the "coating" technology for metal foils are suitable for the processing of electronic materials such as substrates for 5G and base materials for planar heating elements!

At Kawamura Industries, we develop and manufacture materials for electronic applications and provide associated processing technologies. We will introduce technologies that have a proven track record for substrates used in 5G and for planar heating elements. 【Our Technology: Electronic Materials - Strengths of Vacuum Heat Press Coating Technology】 ■ Vacuum Heat Press In prototype and mass production using vacuum heat pressing, we can press without adhesives, allowing us to better utilize the inherent properties of the materials. (Note: We can also accommodate laminated products with adhesives.) - We have a large number of press machines, capable of handling various sizes and temperatures. - There are press machines installed in a cleanroom environment. ■ Resin Coating on Metal Foils Although we operate in a contract processing format, we can combine "metal foil + high-temperature treatment." - Our coating drying oven can handle temperatures up to 260°C, allowing for the drying of high-boiling point solvents. - We can also accommodate polyimide coatings with a high-temperature curing oven that can handle up to 400°C. Including material procurement, we provide consistent support from small lots and prototypes to mass production, so please feel free to contact us. *We are currently publishing an introductory document summarizing what Kawamura Industries can do! You can view it immediately via [PDF Download].

Based on practical experience in support companies and business companies, SBS Marketing Co., Ltd. provides consulting services related to marketing, sales promotion, and customer acquisition primarily in the BtoB (business-to-business) sector. On June 4, 2026, we published a page titled "Do We Tend to Set 'Forecasts' Too Optimistically? The 'Planning Fallacy'." The 'Planning Fallacy' refers to the psychological phenomenon where the time, costs, and risks required to complete tasks are "underestimated," while the benefits are "overestimated." The page explains examples of its occurrence, the factors that lead to it, and methods to overcome it. (Page Overview: Excerpts) ■ What is the 'Planning Fallacy'? ■ Examples of the 'Planning Fallacy' ■ Why does the 'Planning Fallacy' occur? ■ What are the methods to overcome the 'Planning Fallacy'?

Our IP phone service "Rimofon" has been newly listed in the Japan Telework Association's "List of Telework-Related Tools." It is introduced as a telephone response support tool in conjunction with the carrier's FMC (Fixed-Mobile Convergence) service. The Japan Telework Association provides information related to telework, including guidelines for its implementation. It is an organization with a wealth of knowledge on telework and specific case studies. They offer the latest information to companies considering the introduction of telework and work style digital transformation (DX). https://japan-telework.or.jp/news/news_20260601/
