Taiyo Group Accumulated Technology

Formulation Technology
"Formulation Technology" refers to the accurate, efficient, and prompt development of the optimal combination of materials from amongst countless prospective candidates (e.g. synthetic resins, fillers, etc.) in order to achieve the various characteristics and performance required by products.
Mixing and Dispersion Technology
"Mixing and Dispersion Technology" refers to the manufacture of uniformly-dispersed and precisely-balanced ink formulations. In recent years, in conjunction with the ever-decreasing size of electronics, finer ink dispersions have become increasingly more critical and required.

Taiyo Group Main Proprietary Fundamental Technology

Leveraging its photolithography and insulation technology, Taiyo Group has built its foundations on solder resist and other printed wiring board materials.
