205
The coplanarity laser module is combined with optical component centering, and is used in a
vision module. Components with bent or missing leads are detected and disposed of, if neces-
sary.
7.9.2 Technical data
Component range: Can be used for ’gull wing’ package forms, spacing > 0.3 mm
and maximum component size 55 x 55 mm². Other restric-
tions are associated with the machine configuration.
Measuring principle: Contact-free measurement by laser triangulation
Algorithm functions: JEDEC standard - calculation of the placement plane; all
deviations are determined in relation to this plane. If the com-
ponent 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’.

7.9.3 Safety instructions
The sensor works with a semiconductor laser of wave length 670 nm (visible/red).
The maximum optical output is £ 1 mW.
The sensor is classified as laser class 2.
– When operating the sensor, always follow the relevant regulations of VDE 0837 concerning
"Radiation safety for laser equipment" and German accident prevention regulation entitled
"Laser radiation" (VBG 93).
– Also follow the accident prevention regulations applicable in your country.
As a precautionary measure, an audible or visual warning should be emitted to signal that the la-
ser is in use.
The following information plates are attached to the front and back of the sensor housing:

Fig. 7.9 - 2 Identification of laser class 2 for the sensor
The working laser is signaled by an LED (see Section 7.9.4.2).
NEVER look directly into the laser beam, despite the low laser output. The beam is visible, so the
eyes will be protected by the natural eyelid-closing reflex.
WARNING 7
Only authorized personnel may open the housing of the optical sensor.
For repair and servicing, always return the sensors to SIEMENS A&D.

7.9.4 Overview
7.9.4.1 Analysis unit
The coplanarity laser module consists of two components: the analysis unit with its control sec-
tion, and the laser module. The analysis unit is located in the control unit (see Fig. 7.9 - 3
). The
operating state is indicated by three green LEDs on the front panel of the analysis unit:
Press the RESET key to initialize the coplanarity laser module.
7.9.4.2 Laser module
The laser module is fixed to a supporting frame on the right-hand side of the machine (see Fig.
7.9 - 4
). Two red LEDs and one green LED signal the operating states of the laser module:
