ABSTRACT:
An apparatus and a method is disclosed for providing a controlled separation of a structure that has been screened from the screening mask. A dampener pad floats with the mask as the screened structure is being separated from the mask. The mask is held in place by the dampener pad while the structure completely separates from the mask. The dampener pad assembly, then, in a controlled manner, brings the mask back to the original position, and the mask is then ready for the next screening operation.
