Many new technologies and products related to flexible circuits were introduced by mid-sized manufacturers at JPCA Show 2019.
Oki Cable displayed several unique technologies that included stretchable and transparent circuits. They are proactive with introducing 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 3-D-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 for managing thin fragile projects in the manufacturing and assembling process, especially in small-volume and prototype production.
Low-loss circuits are a growing category for 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 reported increases in inquiries due to the potential market from 5G devices.
