2.2.4 Overview of the Nozzles

This section gives you an overview of the currently available dispenser nozzles.

Item number Designation Dispenser nozzle shape

03094220-xx Flat jet FD6100 (100 microm.) 1014

03094182-xx Needle jet ND6150 (150 microm.) 1016

03120082-xx Needle jet ND6250 (250 microm.) 1019

2.2.5 Overview of Glues

The Glue Feeder currently supports the following adhesives:

●

Heraeus PD-205A

●

Loctite 3621

●

Loctite D125F

●

Delo Monopox MK096

As the various glues have different properties, you need to individually adjust the pressure at the

cartridge, at the jet valve and the temperature of the glue for each type of glue. The temperature

can be set via the station software or, if needed, directly at the Glue Feeder.

The following table shows an overview of the optimum values for the individual glues.

Loctite D125F 3bar 4.5bar 53°C

Delo Monopox MK096 1.5bar 3.0bar 40°C

General notes about temperature

The temperature of the glue in the jet block is read by a sensor and then adjusted to the set TAR-

GET value. If no TARGET value has been set, the glue temperature will be set to the default value

of 40°C

. The temperature can be set from 40°C to a maximum of 70°C.

The permissible tolerance range for dispensing is ±3°C of the set TARGET value. The Glue Feeder

sends a signal to the machine whenever this range is left or entered again. Dispensing is not pos-

sible outside the tolerance range.

The temperature is increased using the nozzle heating function on the jet block. A reduction in tem-

perature is only reached passively by cooling down via the ambient temperature. To save glue, the

nozzle heating is switched on automatically if there is a processing break of longer than 10 minutes

at the Glue Feeder.

General notes about pressure

If the Glue Feeder is not supplied with compressed air via an external source but from the com-

pressed air connection of the placement machine, we recommend that the pressure reducer for the

pressure at the jet valve is set to max. 4.5bar. A pressure of 2 to max. 4.5bar is usually sufficient

for all common SMT adhesives.

If you want to use special adhesives in your production, which need a higher dispensing pressure

than 4.5 bar, the Glue Feeder should in this case be supplied via an external compressed air con-

nection, separate from the placement machine.

Background: If you set higher dispensing pressures than 4.5, you may experience brief recurring

pressure drops to 4.5 bar at the compressed air connection of the placement machine, if there are

other compressed air consumers (e.g. the tape cutter) being activated. This could cause irregular

glue droplet sizes to be produced.

NOTICE

Using the same temperature profiles

To enable you to use uniform temperature profiles for the various adhesives required for

multiple Glue Feeders in the same production environment, we recommend adjusting the

individual Glue Feeders to one another with the Glue Feeder calibration device (item no.

03214618-xx). See 4.3.3

"Calibrating the temperature regulation" [}64].

2.2.6 Examples of Glue Dots

This section includes several examples of the settings which can be used to create glue dots of

various different diameters and heights.

The glue may differ in its behavior, according to the condition of the component surface (rough or

smooth).

If there is solder paste on the board, you should glue with a diameter of 0.9 mm, to ensure that the

required glue dot height is reached.
