Double layer detection of solar wafers in cell production

Thin wafers can accidentally stick together, and will break in later processes. SICK’s UM18-20012 ultrasonic sensor has double sheet detection built in, and works on printed wafers. Another example of SICK’s commitment to sense where the process requires it.
