Squink desktop PCB printer now comes with Multilayer Package, a multilayer board option. Can inkjet-print conductive traces, dispense solder/glue and pick-and-place components on rigid or flexible substrates. Includes a new cartridge containing insulating ink and a curing lamp. The latter is placed on top of the circuit to cure insulating ink via UV light while protecting eyes and skin of users. Specially formulated ink is electrically insulating and compatible with existing Advanced Ink, and is printable on top of conductive traces or an insulating layer. Can also be used to improve printing on materials not easily compatible with advanced ink such as porous, stretchable or textile materials. Design using standard CAD tools such as Eagle, Altium and KiCad. Imports Gerber files.
