Abstract
Multiple nozzle arrays are formed from an assembly of at least one pair of plates having intersecting channels for receiving orifice elements and sealant. The joined plates, with inserted orifice elements in one channel and sealant in the other channel are then mounted vertically or at an appropriate angle and exposed to a temperature sufficient to cause the sealant alone to melt and to flow by capillary action to seal the orifice elements in a void-and-bubble free manner and to seal the plates to form a plate block. After cooling, the plate block is sliced into multiple nozzle wafers.
