Laser Measurement
The Laser Measurement is one of the Algorithms. Use the laser height sensor to measure the height in the step. If it is
judged whether or not the measurement result is within the range set by the user. When the measurement result is within
the range, it is determined as “OK”. If not, it is determined as “NG”.

Major applications
Checking Body Lifting
Measures the BGA height to detect defective connections caused by a Body Lifting of BGA, pinching parts and so forth.
It also measures the height and other parameters of recessed polarity marks to detect the polarity.
Checking Lifted Lead
Measures the differences in heights of lead parts such as a QFP and SOP to detect a Lifted Lead.
Checking Chip Tombstoning
Measures the differences in heights of chips and other parts to detect a Chip Tombstoning or presence/absence of
parts.
TIP
For instructions on how to use the laser height sensor, see the option manual "Laser height sensor" at the end of this
manual.

3D projector
The main camera of the 3D projector captures the projector images of a device at 4 directions for three-dimensional
measurement.
When extracting a part or a lead to inspect one for defective lifting for instance, designating three-dimensional heights
enables to do so conveniently and accurately without variation.

4D angular camera
The 4D angular camera captures images obliquely from 4 directions.
When the visual inspection has to judge pass or fail (OK or NG) at the repair station, inspecting 4D images makes the
judgment easier.
Since the 4D images are saved in the program, it can be tuned offline.
