Launched in 1965, OKI's printed circuit board business has won renown for its large, multilayer boards based on its prominent technologies, including the world's first 102-layer printed circuit board. To expand its EMS business, OKI faces the need both to expand its printed circuit board business and to further enrich its integrated production system, OKI’s advantage in EMS business, ranging from printed circuit boards through assembly of final products.

Since launching its printed circuit board manufacturing in 1969, Yokogawa Electronic Corporation has manufactured a wide range of printed circuit boards for in-house control and measurement instruments with high-reliability at Ome Factory, which is the only domestic production site.

In response to continuous facility investment and significant technological progress in printed circuit board manufacturing and assembly, Yokogawa Electronic Corporation had recently been repositioning its printed circuit board business while moving forward with business structural reforms.
