Electronics Division

Professionals leading electronic equipment manufacturing technology for the next generation.

Due to our abundant experience and lots of achievements, our technologies have been developed. In addition our operation capability is available all day long and all year round. These strengths have enabled our flexible and advanced proposals and designs as well as high-quality and speedy productions.For automotive components, measuring equipment, medical devices and even more, we can supply circuit boards whether quantities are small or large, to cover our customers’ request, taking advantage of our state-of-the-art technologies and facilities. Also our sophisticated procurement for electronic components, prototyping of circuit boards and mounting on them develop our integrated production system, which provides real-time deliveries, and which also saves cost.

Production facility infrastructure that supports the electronics business

The bridge of technology closely connecting the Design and Development Division, and the Electronics Division

One of the important tasks for the Design and Development Division is to design circuit boards considering layouts for components to be mounted. The Electronics Division arranges the commercialization of those works taking advantage of its technical capabilities. This cooperation is closely arranged and strongly supported by highly sophisticated provision of our plant. Even in case of an earthquake, our strong plant equipped with various advanced facilities will sustain our supplying and high quality.

Our Plant Provision

Disaster Prevention Activities

The plants which well withstand natural disasters such as earthquakes. To minimize earthquake damage, and not to cause our customers logistic problems, our plant is equipped with vibration control dampers. AEDs are available not only for our employees but also the local residents.

Vibration control damper

Countermeasure for Foreign Substance

All of the plant entrances are equipped with air showers, and strict one-way traffic prevents foreign particle and dust to maintain the cleanliness of the plants.

Air shower

Initiative for static protection

An anti-static floor material is used throughout the factory to manufacture the products that are safe and reliable. In addition, the company makes sure that grounding is provided for each electrical equipment and the employees wear wrist straps, etc. to prevent the parts from being damaged by static electricity.

Facility with anti-static protection

Temperature and humidity control system

The temperature is automatically controlled from 20 to 28 ℃, and the humidity 40% or higher in our entire plants for electrostatic countermeasure.
