Partner EMS

We provide “coordination” technologies backed up by our knowledge and experience as a Tier 1 supplier of automotive equipment.

We also occasionally coordinate with OEMs (car manufacturers) in place of Tier 1 suppliers by acting as a partner with the same perspective as Tier 1 suppliers in addition to serving as a bridge between Tier 1 suppliers and device suppliers. You will further strengthen your core competencies and Nippon Seiki will compensate in the places where you need help.

For example, Nippon Seiki complements the electronic system area in Tier 1 suppliers who specialize in mechanical parts to contribute to the strengthening of the mechatronics business of tier 1 suppliers.

Switch from a vertically integrated business model to an open business model and leave to Nippon Seiki the fields where you have little experience. This will allow us to provide efficient and smooth product design, production design, parts procurement and manufacturing.

We also handle evaluations (e.g., automotive reliability tests) at your request.
