Latest Patents

Higashino's recent patents include a recognition device, a bonding device, and a method of manufacturing a circuit device. These inventions address specific challenges associated with wire bonding, where inert gases used to prevent substrate oxidation can cause shimmer due to temperature differences. This shimmer negatively impacts the pattern recognition precision. To combat this issue, Higashino's bonding device is equipped with shielding lids located at the upper and lower parts of a ring illumination and at the lower part of a lens barrel. By preventing the entry of nitrogen gas, which contributes to shimmer, the recognition precision of the recognition camera is significantly improved, thus enhancing wire bonding precision.

Additionally, his recognition device incorporates a shimmer prevention blow mechanism positioned between the ring illumination and working hole. This machinery effectively disperses the nitrogen gas, thereby preventing shimmer caused by temperature differences during the bonding process. Consequently, the precision of recognition and wire bonding improves, demonstrating the effectiveness of Higashino's innovations.
