Introduction: screen alignment theory
The camera captures each of the fiducials (screen and board) and sends the data to the
processor. The processor uses this data as well as the calibration data to calculate the
amount of stencil movement required to align the stencil to the board. The processor then
tells the actuators how much to move for this alignment.
