2.2.7 System Requirements and General Restrictions
Preconditions
The Glue Feeder can only be used on SIPLACE machines with the station software from 706.1 and
in SIPLACE Pro from version 10.1 with the X Feeder interface.
Furthermore, the machine must be fitted with a connection to the safety circuit and a connection to
the compressed air supply. The following retrofit sets are available for fitting the required items:
●
Retrofit set Glue Feeder SX12 / DX12, item no. 03091006-xx
●
Retrofit kit for Glue Feeder SX4 / DX4, item no. 03091007-xx
●
Retrofit kit for Glue Feeder X-Series, item no. 03091008-xx
Restrictions
A gantry can only work with one Glue Feeder.
The Glue Feeder is not designed for use of
●
Solder paste
●
Anaerobic curing glues (such as superglue)
●
UV-curing adhesives
When using UV-curing adhesives, the user is responsible for ensuring that the nozzle opening
of the glue is not exposed to UV light.
Radiation with UV light can lead to unintentional curing of the glue in the nozzle.
●
Transparent adhesive
In some cases, it might not be possible to inspect transparent (clear) adhesives with the Vis-
ion system.
Other restrictions
●
The jet valve must not dry out i.e. be operated without adhesive.
●
Bridging the safety circuit is prohibited.
●
The Glue Feeder may only be cleaned using the cleaning agents prescribed by the glue man-
ufacturer or ASMAS.
●
The programming of glue dots which exceed the diameter of the component at any point is
prohibited (risk of contamination!)
●
When applying glue to narrow edges – even when these are within the component body - only
dispense glue dots which have been adjusted accordingly in their size, otherwise there is a
risk of glue dot division and uncontrolled spurting away of glue at the sides.
●
MELF and SOD (glass diode) components
Due to their round bodies, MELF and SOD (glass diode) components are in principle not suit-
able for glue application. The round body shape poses an increased risk of placement head
contamination. We therefore recommend that these components are not glued or only glued
after thorough assessment of the risks.

2.2.9 Setting the Jet Plunger
NOTICE
Increased wear when pressure is higher
The jet plunger is factory set to 60N (corresponds to 0.6mm plunger setting). This setting
allows the SIPLACE Glue Feeder to process common epoxy resin-based SMD adhesives
reliably and in high quality.
After changing this setting, you may need to adjust the characteristics at the station.
Please note that higher settings (>60N) will lead to increased wear of the jet plunger and
particularly to the dispenser nozzle.
We recommend that you check the plunger setting in the following cases:
●
General check of factory setting to 0.6 mm
●
Same setting when using multiple Glue Feeders at your site
●
Optimization of glue dot quality
General check of factory setting to 0.6 mm
If the quality of the glue dots should deteriorate, despite regular maintenance, and if this can not be
remedied with the temperature and pressure settings, the plunger setting can be checked using the
plunger measuring system "Measuring system - plunger adjustment", item no. 03126592-01.
Checking and setting of the jet plunger is described in the service manual for the Glue Feeder item
no. 00197278-xx, chapter "Replacing Spare Parts", in the section about "Jet Valve P-Dot".
Same setting when using multiple Glue Feeders at one site
To avoid differences in the size and quality of the glue dots between the individual Glue Feeders,
the Glue Feeders can be checked with the plunger measurement system and adjusted, if neces-
sary.
