Description: Ion Chromatography is an advanced, highly-accurate test process to identify contaminants on a PCBA which could lead to failure over time in the field, such a shorts between closely-spaced pads due to dendritic growth.
Process is optional and is turned OFF by default.
Major Cost Drivers -- PCBA Ion Chromatography
Ion Chromatography Cycle Time is either the sum of a total immersion in water, or a sum of testing specific locations.
If PSO Ion Chromatography Method = Full Immersion:
Full Immersion Process Time = Board Load Time +
((Ion Chromatography Run Time) *
(MonitorPercentage/100))
Board Unload Time + Board Inspect Time
If PSO Ion Chromatography Method = Spot Test:
Spot Test Process Time = Board Load Time +
((Ion Chromatography Run Time *
Ion Chromatography Spot Test Quantity)*
(Monitor Percentage/100))+ Board Unload Time +
Board Inspect Time
- Board Load Time = (Machine variable)
- Board Unload Time = (Machine variable)
- Board Inspect Time = (Machine variable)
- Ion Chromatography Run Time = (Machine variable)
- Ion Chromatography Spot Test Quantity = (Machine variable)
- Monitor Percentage = (Machine variable)
