R & D section

R & D team, in design process, carries out mechanical, optical design and simulation by using leading edge desgin tools for customer’s request. Ensuring mechanical consistency by 3D CAD, the problem occur beforehand, which can help to develop better products.
Moreover by using automatic measurement R &D team improves and innovates the design quality.


Production section

Automatic soldering machines and automatic appearance inspectors were installed in production section. Their goal is satisfying customers supplying more stable and higher reliable products. Manual soldering is also carried out by workers who are given education and recognized by our company. In order to keep traceability for a certain product, laser marking device was installed.
Lot management per package is not only success in our factory, lot management per products is also effective. Production section makes diligent fullfilling of requirements form customers.


Manufacturing control section

Purchasing department manages material by barcode and logistics flow to acceptance inspection in real time. Also Manufacturing control section checks strictly manufacturing process and quality in subcontract factory and is making efforts to maintain quality day to day.


Quality control section

Quality control promotes green procurement, RoHS compliant and REACH which are required for environment today and compiles a database. Additionally they manages and checks environmental load material like toxic materials, noise and pollution.



Shinkoh manages quality, automatize manufacturing process and installed leading-edge machines and equipments for the purpose of satisfying customers.

Clean room

Shinkoh has more than 300 square meters clean room to manufacture discrete semiconductors such as LEDs, Photo diodes, Photo transistors and COB(chip on board). Manufacturing process, storage of chip, assembly, forming process inspection can be carried out in this facility.


Shinkoh have several automatic assembly equipments, inspection devices, evaluating apparatus related with production, assembly, inspection and storage for treating advanced technology of photo sensors.
