Tanaka's gold bonding wire for semi-conductors is the wire which is produced under strict quality control, and has excellent properties in terms of purity, preciseness and strength. Tanaka's gold wire is produced through many production stages in the belief that every production stage is important for the production of high quality products. The operators and engineers of the gold bonding wire section at Tanaka are always forced to observe strict control over items with responsibility and try to achieve the designated target of quality control. At each production stage, the density of dust in every workshop is kept well below the lever of 2000 pieces (over 0.5 micron size/piece/cubic foot). The production is carried out in such clean atmosphere that impurity contamination never occurs at any production stage. Tanaka always guarantees the purity of 99.9% or more!
