7.13 Coplanarity Laser Module
[00119719-xx] Coplanarity module SIPLACE X-/CA-/D-series
7.13.1 Functional Description
The coplanarity laser module is used to measure vertical bending of the leads. The lead length is
measured without contact using the laser triangulation principle.

The TwinHead picks up the component to be checked, enters it optically with the component cam-
era (see section 7.4
, page 463) and moves in succession all four sides over the fixed laser beam
of the coplanarity laser module. In this way, every lead is scanned from below by the laser beam.
The laser light scattered by the underside of the lead is recorded by a sensor, and is then used to
calculate the exact position of the lead with respect to the PCB.

The position values thus calculated are compared against the limit value specified by the user. If
they exceed this value, the component is disposed of or returned.
The coplanarity laser module is used in combination with the optical component centering mode.
Components with bent or missing leads are detected and disposed of, if necessary.
7.13.2 Technical Data
Component spectrum: Usable for ’Gullwing’-component packages, pitch > 0,3 mm
and maximum component size 55 mm x 55 mm. Further
restrictions depend on the machine configuration.
Measuring principle: Measurement without contact via laser triangulation
Algorithm functions: JEDEC standard - calculation of contact level: all deviations
are calculated in relation to this level. If the component is
angled with respect to the vacuum nozzle, as can happen if
an adapter is used, then it will have no influence over the
choice between ‘good’ and ‘bad’.
