The Top Worst Nozzle Segment/Holder Monitoring Dashboard lets you quickly identify the worst nozzles at a site, on a line, and/or on a machine that are having numerous mispicks. Because the report tracks mispicks by segment/holder, it works across vendors that serialize nozzles (such as Fuji) and vendors that do not (such as ASM). This helps maintenance engineers identify nozzles that may need to be serviced regardless of the vendor.
You use these filters to select which nozzles you want to view:
- Site: Select the site you want to view.
- Error Scope: Choose the machine vendor you want to view (ASM, Fuji, etc.).
- Line: Select the line you want to view (or "All" for all lines).
- Machine: Select the machine you want to view (or "All" for all machines).
- Bucket: Specify the duration of each point on the trend chart (see below) and each band on the heat map (see below). For example, if you set Bucket to 1 hour and view 12 hours of data, you'll see 12 points on the trend chart representing one hour each, and you'll see 12 bands in the heat map, each one hour long.
- Worst Nozzles: Lets you choose to view All segments/holders or a set of one or more segments/holders of your choosing (using the multi-select checkboxes on the pulldown menu).
- Number of Nozzles: Choose how many segments/holders you want listed in the heat map (see below).
Remember to use the date picker in the top-right corner to choose the time period you want to view.
After setting your filters, you will see the following data for the selected site and line(s):
- Total Mispicks
- Total Placements
- Attrition (PPM)
- Total Mispicks by Line
- Total Placements by Line
- Mispicks in PPM by Line
Placements and Attrition timelines
You will also see Total Placements and Total Attrition on a timeline spanning the time period you have chosen with the date picker:
Worst Nozzle Mispick Heatmap
Finally, a heatmap will show you how many mispicks each of the worst nozzles are making during each bucket over the time period you've chosen. Lighter colors indicate a larger number of mispicks per bucket.
In the below screen shot, you can see that the segment/holder highlighted in blue experienced rapidly increasing mispicks (shown by the lightening color of the bars) then returned to no mispicks, perhaps because its nozzle was serviced. Now the segment/holder highlighted in red is experiencing rapidly increasing mispicks and should be evaluated for servicing.
