Cameroon DF cell secondary printing positioning machine

The device can determine the angle difference and displacement difference between the secondary printing screen and the primary printing cell, so as to complete the precise printing of the cell (silicon wafer). The angle accuracy is required to be as high as 0.01, and the displacement accuracy is required to be as high as 5μm. Compared with the existing technology, our company adopts a multi-eye measurement scheme, which has higher precision and faster efficiency. This product has applied for 5 invention patents.
