Paste Volume Prediction
2Di combines the results of board and stencil inspections, and using a propriety
formula calculates the predicted paste volume. This is only available while the
inspection is set to advanced for both board and stencil.

MACHINE OPTIONS
In the example shown the aperture is 100% clear. The paste on pad value was 100%.
This can be represented by the following model of the printed paste :
This is represented by the following model of the printed paste :
Top face equals area of
aperture not blocked by
paste, ie 100%.
Top face equals area of
aperture not blocked by
paste, ie 60%.
Bottom face equals area of
paste on pad, ie 100%.
Bottom face equals area of
paste on pad, ie 90%.
Aperture
From this information the system predicts the volume of paste, in this case 100%.
From this information the system predicts the volume of paste, in this case 74.48%.
In the following example the aperture has a blockage of 40%. Therefore the aperture is 60%
clear. The 60% is equal to a rectangle of the same size as shown below. The paste on pad
inspection result is 90%.
