Abstract: Exemplary electroplating systems may include a vessel. The systems may include a head that is configured to hold a substrate. The head may be positionable within an interior of the vessel. The systems may include a spray jet array disposed within the interior of the vessel. The spray jet array may include a plate defining a plurality of apertures through a thickness of the plate. The systems may include at least one fluid pump that is fluidly coupled with an inlet end of each of the plurality of apertures.

Abstract: Exemplary anneal chambers may include a base that defines a chamber interior. The base may include a cooling plate within the chamber interior. The base and the cooling plate may be integral with one another. The chambers may include a lid that is coupled with the base. The chambers may include a heater plate mounted in the chamber interior alongside the cooling plate. The chambers may include a transfer hoop movably coupled within the chamber interior. The base may define a first transfer hoop recess about at least a portion of the heater plate. The base may define a second transfer hoop recess about at least a portion of the cooling plate.

Abstract: There is disclosed a spray head for an airless spray gun. The spray head has a tubular housing for removable attachment to the discharge end of an otherwise conventional airless spray gun, adjacent the valve member of the spray gun. The housing is counterbored to form an inner annular shoulder and contains a removable plug that is slidably received within the housing. The annular shoulder is stop for the plug which is retained in the housing at the preselected location by a retainer member that is removably threaded into the discharge end of the housing. The plug has, on its upstream end, a valve seat to engage the valve member of the spray gun and, on its downstream end, a discharge orifice formed by divergent angular bores which intersect a through bore of the plug.
