Electronics

Humidity is an unwanted element in the production of silicon wafers. If, by contrast, the air is too dry, static electricity becomes a problem. Ambient air is monitored and controlled in the production of printed circuit boards for the same reason. Measurement and monitoring of differential pressure is also critical in semiconductor manufacturing. The individual production steps are carried out mainly in strictly controlled clean rooms so that the sensitive electronic parts are not contaminated with foreign particles. In storage, measurement and control of relative humidity prevents corrosion of the sensitive electronic products.
