Electropolishing method including multi-finger contacts

摘要

Systems and methods for electropolishing devices are disclosed. The electropolishing system includes electropolishing fixtures configured to reposition the devices during the electropolishing process.

主权项

1. An electropolishing fixture for electropolishing a device, the fixture comprising:
an anode that receives the device in rotational engagement; a plurality of lever arms, each lever arm including an elongate body with a distal end and a proximal end, an axis of rotation of each lever arm being disposed at and passing through the proximal end of the body and a device contacting surface formed by an exterior distal surface of the distal end of body, wherein the plurality of lever arms are configured to rotate about an axis, move perpendicularly relative to the device, and move tangentially to an outer surface of the device; a controller configured to control movement of the plurality of lever arms such that the movement of the plurality of lever arms repositions the device during an electropolishing process while maintaining at least a portion of the device in contact with the anode and the device contacting surface formed by the exterior distal surface of the elongate body.
