JNS Glass & Coatings is a supplier of AF 32® eco, an alkali-free flat glass manufactured by SCHOTT using a special down-draw method. This manufacturing method makes it possible to manufacture products of between 0.03 mm and 1.1 mm in thickness. Its fire-polished surface results in a low roughness value. Furthermore, the coefficient of thermal expansion of AF 32® eco is the same as that of silicon. For this reason, it is perfectly suited for use as an optical packaging material in the semiconductor industry. Due to its high transformation temperature, AF 32® can be used in high-temperature applications of up to approx. 600 °C. AF 32® eco is available in various wafer formats and is manufactured using eco-friendly refining agents instead of arsenic and antimony.
