Abstract: A method for adjusting a solder paste stencil includes preloading a solder paste stencil in contact with a printed circuit board. Processing warpage is measured between the solder paste stencil and the printed circuit board to determine a dimensional offset strain due to the warpage. A stress to be applied to the stencil is determined by accessing a neural network to output the stress based on the dimensional offset strain. The stress is applied to the stencil to compensate for the warpage.
