#1918 / JPCA SHOW 2019 (Part 2)

This is part two of my observations from the JPCA Show.
Many new technologies and products related to flexible circuits were introduced by mid-sized manufactures at the JPCA Show 2019. Oki Cable displayed several unique technologies that included stretchable and transparent circuits. They are proactive with introducing new materials for base materials as well as conductors and coverlay. Oki Cable provided many circuit examples that featured balances between the materials. They also featured spiral flexible circuits for 3D stretchable wiring using both traditional materials and new elastic materials.

Taiyo industrial, another mid-sized flex circuit manufacturer also displayed transparent flexible and stretchable circuits using new copper laminates and coverlay materials. Taiyo has a supplemental business that uses machines to inspect flexible circuits. Taiyo featured a universal handling robot that can handle thin flexible materials developed for its own manufacturing processes. The robots are capable in managing thin fragile projects in the manufacturing and assembling process, especially in small volume and proto type productions.

Low loss circuits are a growing category for the flex circuit manufacturers (assuming 5G devices will be available this year). Kuraray, a major material supplier in Japan introduced Liquid Chrystal Polymer (LCP) films and its copper laminate. Yamashita Materials, a prototype flex circuit manufacturer in Japan displayed many examples of flex circuit examples with LCP materials designed for mobile devices.
All these companies have reported an increase in inquiries due to the potential market from 5G devices.
