Leak free brush electroplating system
In any overhead job, operators will feel more relaxed and safer. In any systems, the operators won't have to spend days for masking and sealing. Simple protection will be enough. With this unit operators can use toxic solutions like cadmium and silver without any health concern, because the anode returns the toxic vapors back to the chamber and filtered suction line in front of the exhaust valve will take the toxic vapor away. Pit filling anode save the workers time and effort drastically by filling the pits bottom up in one shot.
SUBSTRATE PLATING APPARATUS INCLUDING HYBRID PADDLE THAT SIMULTANEOUSLY CIRCULATES AND STIRS PLATING SOLUTION AND REMOVES AIR BUBBLES
Provided is a substrate plating apparatus capable of simultaneously circulating and stirring a plating solution and removing air bubbles. The plating apparatus includes a hybrid paddle disposed in front of a substrate in a plating bath to stir the plating solution. Here, the hybrid paddle includes a spray assembly for spraying the plating solution toward the substrate and a suction assembly for suctioning air bubbles formed on the substrate during plating, and the spray assembly and the suction assembly are coupled into one body and perform a reciprocating movement along a surface of the substrate to stir the plating solution.

Method and device for the galvanic application of a surface coating
A method for galvanic application of a surface coating, in particular a chromium coating, to a body, for example a machine component. Before the galvanic application of the surface coating, a layer of a compound that can be oxidized by an electrolyte solution that is used, preferably a polyhydroxy compound with a viscosity of at least 1000 mPas at 25° C., is applied to the body. A method for galvanic application of a surface coating, in particular a chromium coating, to a body, for example a machine component, wherein the surface coating is carried out in a closed reactor in an at least two-stage, preferably three-stage process, is also disclosed. An electrolyte solution contained in the reactor at a temperature T1 for carrying out a subsequent process stage is substituted by an electrolyte solution at a temperature T2≠T1. A device for carrying out this method is also disclosed.
MECHANICALLY-DRIVEN OSCILLATING FLOW AGITATION
Systems and methods for electroplating are described. The electroplating system may include a vessel configured to hold a first portion of a liquid electrolyte. The system may also include a substrate holder configured for holding a substrate in the vessel. The system may further include a first reservoir in fluid communication with the vessel. In addition, the system may include a second reservoir in fluid communication with the vessel. Furthermore, the system may include a first mechanism configured to expel a second portion of the liquid electrolyte from the first reservoir into the vessel. The system may also include a second mechanism configured to take in a third potion of the liquid electrolyte from the vessel into the second reservoir when the second portion of the liquid electrolyte is expelled from the first reservoir. Methods may include oscillating flow of the electrolyte within the vessel.

ELECTROPLATING SYSTEM
An electroplating system has a vessel assembly holding an electrolyte. A weir thief electrode assembly in the vessel assembly includes a plenum inside of a weir frame. The plenum divided into at least a first, a second and a third virtual thief electrode segment. A plurality of spaced apart openings through the weir frame lead out of the plenum. A weir ring is attached to the weir frame and guides flow of current during electroplating. The electroplating system provides process determined radial and circumferential current density control and does not require changing hardware components during set up.
