6.17 Coplanarity laser module From software version SR.605.xx 07/2008 EN Edition

The TwinHead picks up the component to be checked, centers it optically using the component
vision camera (see Section 6.6
, page 315) and moves all four sides one after another 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.

Warning label W216 "Laser class 2" on the cover beside the main switch,
item no. 03010316-01 (number per machine: 1)
PLEASE NOTE 6
When the coplanarity laser module is fitted, the machine must be classified as laser class 2. The
laser module is not integrated into the EMERGENCY STOP circuit.
→ Identify the machine with warning sign W216 "Laser class 2", item no. 03010316-xx.
→ Stick warning label W216 beside the main power switch on the cover (see Pos. W216 in Fig.
6.17 - 3
, page 337).

6.17.6 LED displays on the controller
The statuses of the coplanarity module are indicated by LEDs. The LEDs can be found at the bot-
tom of the controller (see item 6 in Fig. 6.17 - 4
