Screen printing is one of the simplest and most cost effective techniques used by electronics
manufacturers. This technique is based on a woven screen that has different thicknesses and
thread densities. To produce a printed pattern, a squeegee blade is driven down forcing the
screen into contact with the affixed substrate. This in turn forces the ink to be ejected through
the exposed areas of the screen on the substrate, and thus, the desired pattern is formed [22].
Polyester and stainless steel are the most common materials used in this technology.
