Claim of US Patent No. 10,091,891

1. An apparatus for printing circuitry comprising:a stage;
an attachment mechanism for affixing a printed circuit substrate onto the stage;
a carriage assembly for holding at least one dispensing head configured to express a flowable printed circuit board material onto the printed circuit substrate, wherein the at least one dispensing head includes:
a plunger; and
a piston detachably coupled to the plunger;
wherein the plunger is configured to be moved by the piston in a downward direction when the piston is coupled to the plunger to dispense the flowable printed circuit board material from the at least one dispensing head; and
wherein the plunger is configured to be freely displaced by the flowable printed circuit board material in an upward direction when the piston is detached from the plunger to terminate dispensing and avoid air being introduced into the at least one dispensing head;
a motorized mechanism for moving the dispensing head in relation to the printed circuit substrate; and,
a control circuit for receiving instructions representing a circuit pattern pathway for the flowable printed circuit board material on the printed circuit substrate and configured to activate the motorized mechanism and the dispensing head according to the instructions.
