Filing a plated through-hole of a circuit board with solder is facilitated by an apparatus which includes a wire solder assembly and a controller. The wire solder assembly includes a wire probe sized to extend into the plated through-hole from one side of the circuit board, and a solder block associated with the wire probe so that the probe passes through the solder block. The controller controls heating of the wire probe, when the wire probe is operatively inserted into the plated through-hole, by passing a current through the wire probe. The heating of the wire probe heats a conductive plating of the plated through-hole and melts the solder block. The heating of the conductive plating and the melting of the solder block causes the solder to migrate into the plated through-hole by capillary action to fill the plated through-hole with the solder.

A method of producing a printed electronic device on a thin PDMS film which includes coupling a first layer of a water-soluble polymer to a substrate and drying the first layer of the water-soluble polymer. The method further includes coupling a second layer of a crosslinkable PDMS polymer to the first layer of the water-soluble polymer and curing the second layer of the crosslinkable PDMS polymer to form the thin PDMS film. The method also includes printing one or more functional layers on the thin PDMS film and drying the one or more functional layers on the thin PDMS film to form the printed electronic device coupled to the substrate.
