World Walk Co., Ltd. was founded in 1987 to the early development of surface-mount LEDs for the purpose of the funds was difficult., This part of the transfer of technology and other companies.
        1990 --- industry into the old variable resistors - potentiometer of manufacturing and production design. According to the initial stage of the CTS technology to the sliding-forming resin substrate for the production of major products. After about 10 months, the technical indicators can not reach the substrate roughness (curvature), as well as the assembly when the foot-side adaptation of the technical bottleneck.
        Shareholders agreed to increase by 1991, back to Japan on the basis of the original technology, in the printed carbon electricity board, Yin Qi. The main products are sliding, as well as the rotary variable resistors.
