What MULTI FINELINE ELECTRONIX does

Multi-Fineline Electronix, Inc. (MFLEX), founded in 1984 and headquartered in Irvine, California, manufactures flexible printed circuits (FPCs) and provides component and module assembly for electronics manufacturers. Its principal technologies include single-sided, double-sided, and multilayer FPC fabrication, SMT and mixed-technology assembly, fine-pitch component placement, and functional testing. The portfolio also includes FPC modules, display solutions, wireless-charging receiver coils, and specialized circuits longer than two meters, serving applications in smartphones, notebooks and tablets, wearables, smart-home products, extended-reality headsets, and new-energy vehicles.\n\nMFLEX operates a direct enterprise-sales model with application engineers involved from customer concept and design through prototyping, new-product introduction, and mass production. Revenue is generated through custom, quote-based fabrication, component and module assembly, and integrated total-solution programs rather than disclosed list pricing. The company has sales and engineering coverage in North America, Asia, and Europe, while four Chinese factories—three in Suzhou and one in Yancheng—provide 237,266+ square meters of manufacturing space. Since its 2016 acquisition by DSBJ, MFLEX has operated as a wholly owned private subsidiary and can combine its FPC capabilities with its parent's touch-panel capabilities in display solutions.
