Since it was founded in 1954, ROHM has consistently pursued a guarantee rate one order of magnitude higher than the industry standard with the motto of ‘Quality First’, achieved through comprehensive quality control and reliability management. By 1964, we already reached a defect rate for resistors of 1 in 1,000,000, compared to 1 in 100,000 with other manufacturers. From then on, we have continued to improve the guarantee rate ahead of the industry, such as by implementing mechanization and semi-automation in all processes.
