Other Factors
Because the bent pin detection is reliant on looking for a very small force in a narrow height range,
anything that can have an impact on the overall stack height will influence reliability and
functionality. Therefore, customers will want to eliminate sources of variation as much as possible.
Figure 68
Board & Fixture Flatness
Any curvature in either the PCB or fixture will affect the height at which the pressing force begins.
Curvature and variation in curvature will make it difficult to evaluate for bent pins. It can lead to
both false positives and false negatives. The resolution is to raise the detection force or increase
the H2 detection height which will limit the ability to detect bent pins.
