Capability
The system can provide 100% inspection for thick-film printing defects on single and
double sided substrates.
 |
Missing print. |
 |
Extra print. |
 |
Contamination. |
 |
Fibers. |
 |
Misalignments in x, y and q of
conductor, resist, dielectric and over-glaze relative to fiducials, other print layers,
holes and substrate edges. |
 |
Unacceptable variations in
line widths, pads, or other printed feature dimensions and postage stamp edge effects. |
 |
Missing scribe lines. |
|
|
|
Operation
 |
Operator places a printed
substrate into the inspection nest. |
 |
The imaging head automatically
scans and inspects the substrate. |
 |
Defects are recorded by type,
severity and location (circuit number / section of circuit). |
 |
Images of all identified
defects may be presented on the operator display for operator review. |
 |
In engineering mode - the
inspection operation is performed interactively with the operator. |
 |
Consecutive defects and defect
population limit alarms. |

Reporting
 |
Production statistics for each
batch. |
 |
Statistical reporting by
defect type for each print layer. |
 |
Measurement data including for
example (SPC data) -distribution, mean, etc. for selected printed features. |
 |
Spatial distribution map of
defects on circuit or substrate. |
|
|
|
Training
 |
Training of new circuits is
carried out using selected good parts and CAD data input. |
 |
The training
operator confirms inspection tolerances for different circuit features and regions. |
 |
Trained circuits are stored in
the systems library database for future call-down. |
