US Patent:

20070177789, Aug 2, 2007

Filed:

Jan 31, 2006

Appl. No.:

11/343317

Inventors:

Jeffrey Harrell - Fort Collins CO, US
James Mahon - Glasnevin, IE
Peter Conlon - Lucan, IE

International Classification:

G06K 9/00

US Classification:

382150000

Abstract:

A solder paste inspection machine carries out the steps of automatically generating inspection data for solder paste deposits, automatically determining a squeegee direction of travel for said paste deposits. It associates the squeegee direction with the inspection data, and feeds the inspection data back to a solder paste printer with an indication of squeegee direction. The direction is determined from three-dimensional range maps, the direction of squeegee travel being in the direction of upward slope.

International Classification:

H01L 21/67
G06N 3/08
H01J 37/32

Abstract:

A system, method and software for generating and receiving information about the AC, DC, RF, voltage, and other characteristics and information provided by components in a system. The information can provide insight into the operational characteristics and functionality of the components, as well as the process and system the components are being used within. This information may be used for preventative maintenance of the components, and to detect changes, issues, failures, events, problems, etc. in the process and system.

Abstract:

A system and method for optimizing maintenance of a remote plasma source comprises recording data from a remote plasma source. The data comprises measurements of one or more operating characteristics of the remote plasma source over a period of time and a plurality of indications of system fault event. The method may include receiving the data; analyzing the data; and determining, based on correlations between the measurements of the one or more operating characteristics and the plurality of system fault events, a threshold of an operating point. The operating point may comprise the measurements of the one or more operating characteristics at a particular time. The threshold signifies a pending system fault event is probable to a defined degree of confidence within a specified window of time. The system provides a notification to perform preventative maintenance on the remote plasma source.
