Paddle chamber with anti-splashing baffles
Electroplating systems according to embodiments of the present technology may include a plating chamber configured to deposit metal material onto substrates positioned in the plating chamber. The plating chamber may include a rotor and a vessel. The electroplating systems may include at least one of baffle positioned in the plating chamber. The at least one baffle may define a plurality of slots. The at least one baffle may be configured to limit or prevent fluid from splashing the rotor or the plating chamber during operation of the plating chamber.
1 . A baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber, the baffle comprising:
an arcuate body comprising a first lateral end, a second lateral end opposite the first lateral end, an inner lateral surface that extends from the first lateral end to the second lateral end, an outer lateral surface that extends from the first lateral end to the second lateral end, a top surface, and a bottom surface opposite the top surface, wherein the inner lateral surface is arcuate;
a plurality of slots, wherein each of the plurality of slots extends through the top surface and the bottom surface of the body; and
at least one mounting tab for attaching the baffle to the plating chamber.
2 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 1 , wherein:
the baffle is positioned at a top of a vessel at least partially above a fluid line of the fluid, the vessel being included in the plating chamber, and wherein each slot of the plurality of slots is characterized by a width of less than or about 25% of a length of the baffle.
3 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 2 , wherein:
the at least one mounting tab defines at least one mounting hole, wherein the at least one mounting tab extends within at least one slot of the plurality of slots, the at least one mounting hole sized to receive a mounting screw.
4 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 2 , wherein:
the at least one mounting tab defines at least one mounting hole, wherein the at least one mounting tab is positioned external to the plurality of slots, the at least one mounting hole sized to receive a mounting screw.
5 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 2 , wherein:
a height of baffle is greater than or about 15% of a length of the baffle.
6 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 1 , wherein:
the at least one mounting tab is a flange positioned on the baffle for coupling the baffle to the plating chamber.
7 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 1 , wherein:
a mesh is positioned in each slot of the plurality of slots.
8 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 1 , wherein:
cross-sectional areas of at least some of the plurality of slots are different.
9 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 8 , wherein:
the outer lateral surface is planar.
10 . The baffle configured to prevent fluid from splashing a rotor or a plating chamber during operation of the plating chamber of claim 8 , wherein:
the outer lateral surface is arcuate.
