Corporate
Profile

[Company strength]
We have been producing transformers and coils since our company’s establishment. We have been accumulating advanced technology for many years for the production of many kinds of products. These include hybrid ICs, automotive ignitors, clock modules, optical-related modules, and ICs for aerospace applications. We also mount, wire-bond, seal, inspect, tape, and deliver ICs provided from clients in wafer or tray form. We have earned the trust of NEC and other customers, and we are confident we can outperform any other company. The strength of our company, along with our technology, is our lineup of equipment to support our production. This includes four wafer cutting machines, six IC mounting machines, 29 wire bonders, nine quality assurance stations (for heat cycling and burn-in), and three component mounting lines. We also possess more than 20 other pieces of production equipment.

[Business description]
Our company has been developing, designing, manufacturing, and selling transformers and coils as well as hybrid integrated circuits (hybrid ICs) in the 70 years since our foundation in 1946. We also manufacture component modules, including SAW filters (commercialized as VHF-band and UHF-band filters) and COB (chip-on-board) assemblies (IC chips mounted and wire-bonded on printed circuit boards). Our company is involved in manufacturing optical interface components, such as optical interfaces and optical-related modules that have come into widespread use in communications lines in recent years.



[Industry]
Electronic component and device manufacturing 

[Strength of products/technologies]
We have the capacity for in-house development of the products that we handle, with design divisions for the transformers, coils, and controllers listed here. Other strengths include our ability to provide miniaturized products and products that feature easy maintenance. This is done by making use of today’s hybrid ICs, and our high reliability, including our technology and production equipment. This led to our certification by the Japanese Aerospace Exploration Agency (JAXA) to assemble aerospace-spec electronic components.



[Representative's message]
Our company began in 1946 as a partner production plant of NEC, manufacturing electronic devices, and especially transformers, coils, and hybrid ICs. We rely on our wealth of experience and expertise gained through manufacturing electronic devices to supply high-quality products. Our aim is to provide products that satisfy a wide range of manufacturers, including our past clients. We have also set our sights on entering other business domains and business fields, such as business areas related to aerospace.

[Company structure for market development/overseas expansion]
We have placed engineers (chief engineers) in our sales division to handle technical inquiries and proposals (technology development). We have also constructed a special system for handling made-to-order products and to cultivate sales channels in new business fields.
