The bent pin detection works the same way. It detects bent pins (or improperly pre-seated connectors)
by looking for a low force value at a height range that is just above where the anvil normally makes
contact with the tool and begins to build force. There is no new or special analysis associated with
SensiPress. The addition of SensiPress has improved error detection by allowing the use of a much
smaller force value (previously 50-100lbs, now 2-5lbs). That enables the detection of fewer and
smaller bent or stubbing pins.
Bent Pin Error Detection
Machines will detect an error when force is detected in the "Early Contact Detection Zone". With
SensiPress Technology we are now able to detect early contact forces in the 2 - 5lbf (see Figure 63).
If the pin is bent too much, it will not generate force in the early contact detection zone and therefore
will not be detected as an error. In cases like this, the overall difference in force will be well within the
normal variation of the pressing process. Therefore, it will be undetectable with typical force analysis
regardless of the sensitivity or accuracy (see Figure 64).
