The highest standards of cleanness, leak-proof and corrosion resistance are typical to the continuously growing semiconductor industry. The highly toxic and flammable gasses which are used in the manufacturing process of flash memories, logic processors, photo voltaic cells and many other semiconductor based products, guide the industry to set a wide range of standards for the gas and liquide flow control components. To support the required flexibility, production standards and quality control. Ham-Let operates a separate unit to support customer’s needs for advanced engineering and fast changes inline with stable and reliable production disciplines.
