Multilayer FPC (multilayer substrate, multilayer flexible printed circuit board)

Ultra-fine lines, high density, and high-resolution flexible printed circuit boards have made it possible to form ultra-fine circuits through the fusion of MSAP technology and via filling techniques! For modularization in medical devices and next-generation communication systems! The miniaturization and enhancement of electronic devices are progressing, and with that, there is a demand for finer circuit formation. 【Features of MSAP Technology】 ■ Circuit formation through electroplating allows for high-precision fine wiring ■ Excellent rectangularity of wiring cross-section contributes to reduced transmission loss ■ Superior for high-frequency substrates/IC mounting By merging these two processing technologies, we have realized "ultra-fine line high-density FPC." #UltraFineLines #HighDensity #FPC #FlexibleSubstrate #FlexiblePrintedCircuitBoard

FPCs are fundamentally related to the structure of hardware, requiring both high precision quality and shortened development periods. On the other hand, the circuit board inspection systems mainly include electrical inspection systems and final appearance inspection systems, which are also adopted in mass production sites for FPCs and package/module type circuit boards. 【Business Description】 ■ Electronic Circuit Board Business - Design and manufacturing of flexible printed circuit boards - Assembly of printed circuit boards, etc. ■ Test System Business - Development and manufacturing of circuit board electrical inspection systems - Development and manufacturing of final appearance inspection systems, etc. ■ Industrial Machinery System (Trading Company) Business - Design and manufacturing of robot FA systems and automation systems, etc. ■ Mirror Polishing Machine Business (Mirak Co., Ltd.) - Manufacturing of mirror polishing machines and grinding machines, etc.

We would like to inform you about the establishment of a new production system for high-density wiring boards and high-frequency boards in our main business, the electronic substrate business, as detailed in the attached document. We expect that this initiative will contribute to the expansion of our business in the future; however, this capital investment has already been incorporated into our plans, and there will be no changes to our performance forecast for the fiscal year ending December 2023. Should any matters arise that require disclosure regarding this matter, we will disclose them appropriately.
