Fiducial structure 11
Recommendation 1
Fiducial structure Black resistive paste as the background, with conductive paste printed on it as
the fiducial.
Recommendation Background 0.75 mm larger than the fiducial on all sides.
Method of illumination Normal light
Advantage Good contrast, good sharpness;
Reference Circuit-board conductor layer
Assessment This combination gives the best results. Highly recommended.
Recommendation 2
Fiducial structure Fiducial made from circuit-board conductor material, e.g. 6119, and overprinted
with passivated glass 4330.
Method of illumination Oblique light
Advantage No additional steps required
Reference Circuit-board conductor layer
Assessment Fiducials are less sharp than for recommendation 1. Recommended.
Recommendation 3
Fiducial structure Fiducials made from circuit-board conductor layer against a free ceramic back-
ground.
Method of illumination Oblique or normal light (depending on the paste)
Advantage No additional steps required
Reference Circuit-board conductor layer
Note Fiducials are less sharp than for recommendation 2.
The fiducial image depends on the surrounding free surface. It may be neces-
sary to teach every circuit separately.
Assessment Recommended under certain conditions.

The SIPLACE F machine is equipped as standard with a nozzle changer for the Pick&Place head.
The scope of delivery includes a nozzle magazine for five nozzles, e.g. four standard nozzles from
the 4xx series, and one special nozzle. Three additional nozzle magazines can be retrofitted, if
required, thus providing up to 20 nozzles. 11
The nozzle magazines (see point 1 in Fig. 11.9 - 8) are each centered with two parallel pins, and
fixed to the mounting plate with a countersunk bolt (see point 3 in Fig. 11.9 - 8). Nozzles are ex-
changed automatically during the placement process. 11
