System and method of producing on-demand three-dimensional (3D) printed devices on flexible substrates such as paper, plastic, or polymer using metal alloy nanopowders at low temperatures of printing in the range of 150 degrees Celsius (C) to 300 degrees C. The printer disclosed herein may employ a computer-aided design graphics file given as an input to the printer. The printer will selectively release and print the metal alloy nanopowders on select areas on the substrate to form a conductive pattern.

A conductive tape formed by laying a conductive pathway on a tape layer is disclosed. Various apparatus and methods for laying conductive pathways to form conductive tape are disclosed. The conductive pathways may be laid by varying the lateral position of the conductive pathway on the tape substrate. Such patterns all stretchable conductive tape to be realized. Multiple conductive pathways may be laid in the tape and the lateral separation of the pathways in the tape may vary. In some embodiments the pathways are formed from conductive yarn or by printing or laying conductive ink.

A component carrier includes a carrier body formed of a plurality of electrically conductive layer structures and/or electrically insulating layer structures, a metal surface structure coupled to the layer structures and a metal body directly on the metal surface structure formed by additive manufacturing.

In solder printer, solder supply device uses positive and negative pressure supply device to apply pressure inside air chamber to move solder cup inside outer tube, such that solder paste is supplied from supply nozzle. Controller, when supply of solder paste from supply nozzle is stopped, performs drive control of positive and negative pressure supply device to decrease the pressure inside air chamber, and uses timer to measure the time required from the starting of decreasing the pressure inside the air chamber to when the pressure inside air chamber has reached a set pressure. Because this required time corresponds to the movement amount of solder cup from the start of supply of the solder paste to when supply is stopped, controller using the measured required to estimate the remaining amount of the solder paste in detail with good accuracy.

Four parts of a unity is described here, centered around the multi-tier conductive circuits. The detachable production platform is a prerequisite for manufacturing of these circuits as described. The solder-dispenser is necessary if the circuits are made of anything but magnetic metal powder, or if the means for containing solder material are made solid, and the device-dispenser replaces conventional pick-n-place machines to provide devices to a circuit much quicker and much cheaper.

The multi-tier conductive circuit that is the central idea and the final product of the presented innovations is highly flexible and highly cost efficient.

The trend of miniaturizing all kinds of electronic equipments has been the outset for these innovations and it is our firm belief that all the industry could benefit highly from such a circuit.
