Corporate ProfileHistory of TOMOEGAWA

Electronics age
TOMOEGAWA technology makes a great leap into the worldwide market
Developing the related products that has become the international standard for electronic devices and semiconductors
Historical background
Rapid growth in electronic equipment and semiconductor markets

As various electric and electronic products spread to the market, high density and high integration of semiconductors made rapid progress. Advanced electrical engineering was required such as electrical insulation between minute circuits, durability and dimensional stability, and moreover, cutting-edge polymer electronic materials with superior electrical insulation were demanded.

Developed products
“Lead Frame Fixing Tape” which became the basis of International Standard
High-performance electronic component materials that support the electronics industry

Since entering into the business of polarizing film adhesion processing under clean environment in 1977, TOMOEGAWA tried to adopt its newly acquired technology of coating & laminating under clean environment into the market of electronic materials. In 1984, TOMOEGAWA succeeded in original development of "Lead Frame Fixing Tape" used inside the semiconductor package by taking advantage of the electrical insulating technology cultivated over many years with the electric insulating paper. The highly reliable “Lead Frame Fixing Tape”, proven by TOMOEGAWA’s outstanding technology, was positioned as a designated product by IC manufacturers all over the world, and has become the basis of international standard.
