Sumitomo Electric Co., Ltd. develops ultra small diameter drill bits

The Sumitomo Electric Hard Materials Division has developed an XF1 superalloy made of 90 nanometer ultrafine WC for the manufacture of printed circuit board drills with a diameter of 0.05 to 0.2 mm. Although the existing raw materials are also granules, they grow up during the sintering process, and the new technology developed by the company can suppress the growth thereof, thereby realizing the high hardness and high strength of the printed circuit board drill bit. The drill bit of 15000 holes with a diameter of 0.1 mm has a zero breaking rate. It is estimated that 1.5 to 2 million pieces will be sold at the beginning of the year. Sumitomo Corporation will also expand the XF series of materials for the production of precision molds.
