Ion Chromatography

Category: Testing

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)
