Business Lines

In the current environment of further developing economic globalization, global manufacturing has now become usual.
SIIX is a unique global company that responds to various outsourcing needs in manufacturing from the “global procurement” which is the biggest challenge for global manufacturing to “logistics” and “Electronics Manufacturing Services (EMS)”.
SIIX is a company that cannot be pinned down to a “particular line of business.”


SIIX EMS is an outsourcing business that takes on all or some of the manufacturing of OEM makers, and is run on a global base including the procurement of required components.

We procure components and materials from around the world, including Japan, and manufacture products at our own and cooperating factories, which are spread globally.
SIIX EMS undertakes various types of manufacturing, including producing modules and some finished articles, outsourced from OEM makers, centered on circuit mounting on electronic substrates, which are used widely in electronics devices.
The feature of SIIX EMS is its one-stop service, including trading and logistics.


We offer DFM technical support services which improve development of method of production, design of circuit and process for OEM makers for their mass production.

One function toward improvement of productivity and product quality for OEM makers: DFM(Design For Manufacturability)
The other function toward proposal of efficiency for OEM makers: DFL(Design For Localization)
Both technologies are accumulated by our manufacturing know-how for long time EMS experience.
