Abstract
The present disclosure includes barrier devices for use in an apparatus used to form lapping plates. The barrier devices can contain liquid on the surface of the lapping plate platen. The present disclosure also involves related methods.
Claims19
1) An apparatus for processing a major surface of a lapping plate platen, wherein the apparatus comprises:
- a) a rotatable platter configured to secure and physically support the lapping plate platen during processing of the major surface of the lapping plate platen;
- b) one or more liquid dispensers configured to dispense one or more liquid treatment compositions onto the major surface of the lapping plate platen;
- c) a movable barrier mechanism, wherein the movable barrier mechanism comprises one or more ring segments that can be securely adjusted from an open position to allow one or more liquid treatment compositions to pass through between the barrier mechanism and the outside top perimeter of the lapping plate platen to a closed position so that the one or more elastic ring segments form a barrier that extends above the major surface of the lapping plate platen to substantially contain one or more liquid treatment compositions on the major surface of the lapping plate platen during one or more processing steps of the major surface of the lapping plate platen.
14) A barrier ring assembly configured to be removably retained against a lapping plate platen during processing of a major surface of the lapping plate platen, wherein the ring assembly comprises:
- a) a clamp ring having an adjustable inside perimeter that can be retained against an outside perimeter of the lapping plate platen, wherein the clamp ring has an inside perimeter wall, an outside perimeter wall, and slot between at least a portion of the inside perimeter wall and the outside perimeter wall;
- b) a ring that can be slidably positioned within the slot so that the slot supports the ring, wherein the elastic ring can be retained against the outside perimeter of the lapping plate platen, wherein when in a closed position the ring extends above the major surface of the lapping plate platen and forms a barrier to substantially contain a liquid treatment composition on the major surface of the lapping plate platen during processing of the major surface of the lapping plate platen;
- and
- c) a latch that physically engages the clamp ring and is configured to securely adjust the inside perimeter of the clamp ring from an open and removable position to the closed position that retains the clamp ring and ring to the lapping plate platen to form the barrier to substantially contain a liquid treatment composition on the major surface of the lapping plate platen during processing of the major surface of the lapping plate platen.
19) A method of processing a major surface of a lapping plate platen, wherein the method comprises:
- a) positioning a lapping plate platen on a rotatable platter, wherein the rotatable platter is configured to secure and physically support the lapping plate platen during processing of the major surface of the lapping plate platen;
- b) actuating a movable barrier mechanism to a closed position to form a barrier that extends above the major surface of the lapping plate platen to substantially contain one or more liquid treatment compositions on the major surface of the lapping plate platen during one or more processing steps of the major surface of the lapping plate platen, wherein the movable barrier mechanism comprises one or more elastic ring segments that can be securely adjusted from the closed position to an open position to allow one or more liquid treatment compositions to pass through between the barrier mechanism and the outside top perimeter of the lapping plate platen;
- and
- c) dispensing at least one liquid treatment composition onto the major surface of the lapping plate platen to process the major surface of the lapping plate platen while the movable barrier mechanism is in the closed position.
