Beginning with programming and recompiling and equipment maintenance, the role of the technology department crosses over into total process and production management. Repeated tests are conducted for electronic characteristics using programs that run IC chips and peripheral equipment to determine the viability of designs in accordance with client requests. 24 hours a day, 365 days a year, our technical staff keeps a watchful eye on a testing environment rigorously controlled for dust, temperature and humidity.
 |
 |
| Before IC chips can be sent into the marketplace, they must in fact pass through various processes. This key area is borne by the specialists in each section. Maintaining high product quality for a large quantity and variety of IC chips is accomplished through strict checking by our staff, combining specialized knowledge and technique with cutting edge devices. Zero defects is the everyday theme at Genryo Electronics. |

The IC chips that we at Genryo Electronics take a hand in eventually arrive in the end users hands as products. The joy this brings is our greatest asset. However, because "We want to feel even more user joy" we are making this a reality by extending our business in the communications field by opening a DoCoMo Shop in Imajuku and an NTT DoCoMo Shop in Susenji. With NTT DoCoMo mobile phones as the nucleus, we plan to bring products and services that conform to the area.
Considering product confidence as the norm and we pride ourselves on providing service from the customer's point of view. By responding in good faith to each and every customer need and idea with sound knowledge we will continue to accumulate the trust and results we so highly value.
