Sir, i want help. i have a table on which I locate PCB for printing. it should match to the Stencil. The table has X, Y& Theta movement. PCB & Stencil has Two marks loacated diagonally. if they match then PCB & stencil are aligned. What is the formula to calculate the distance X , Y so that after adjusting X & Y the PCB & stencil will match to each other?
