Figure 1. Fabrication of soft PCBs using stencil printing and screen printing.

Figure 1

(a) Picture showing the stencil printing of Ag-PDMS composites. (b) SEM picture of the stencil printed lines with highest achieved resolution. (c) Microscopic images showing the cross sections of stencil printed Ag-PDMS with 25vol% (top) and 13vol% (bottom). (d) Picture showing the setup for screen printing on 8″ wafers. (e) Microscopic image of finest screen printed lines (black) and spacing (white). (f) Microscopic image showing typical defects like short circuits or delamination of the PDMS layer from the glass substrate. (g) Picture of very long screen printed tracks. Scale bars are 0.1 mm in (c), 1 mm in (b), (e) and 10 mm in (g).
