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 combined with optical component centering, and is used in a vi-
sion module. Components with bent or missing leads are detected and disposed of, if necessary.
7.12.2 Technical data
Component range: Can be used for gull wing components, pitch > 0.3
The component size and lead pitch are limited by the component
position detection system, i.e. max. size 43.0 x 43.0 x 11.0 mm³.
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 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’.

Safety: The coplanarity laser module conforms to laser class 1, when
installed in the machine. The module will not work when off the
machine unless further devices are installed or the protective func-
tions are modified. If the protective functions on the device are
bypassed, the machine automatically conforms to laser class 3B -
(Risk of injury to eyes and skin) and thus requires protective mea-
sures to VBG 93.
7.12.3 Safety instructions
DANGER
NEVER modify or bypass safety devices on the coplanarity laser module! 7
With no protective measures, the coplanarity
laser module conforms to laser class 3B.
(7.12 - 2
).
This means there is a risk of injury to eyes
and skin! For this reason, you should
NEVER
bypass the safety devices!
Fig. 7.12 - 2 Identification for laser class 3B
The following safety devices must be installed on the machine if the laser module is to be operated
in laser class 1 without risk to the eyes and skin:
Invisible laser radiation
Do not expose the beam
Class 3 B Laser Product
1mW max., 670nm; n. IEC 825-1(1993)

The interlock line is connected in series with the switches for the protective hood. This protective
function is maintained even if the key switch is turned to bypass the protection. This means that
the laser module can only be used if the machine is closed!
DANGER
The safety guarantee is automatically invalidated if safety devices are modified or bypassed!
The user must also conform to the guidelines issued by the umbrella organization of employers'
liability insurance associations – VBG 93 – i.e
- Registration with the employers’ liability insurance association
- Appointment of a laser protection officer
- Drawing up guidelines for use of the module 7
