A nozzle changer for the revolver

head can be installed to the left of

the PCB conveyor with no loss of

feeder locations. It will change the

set-up of the placement head

quickly and reliably for the specific

nozzle configuration valid for a job.

Damaged or faulty nozzles can be

exchanged via the menu function.

SIPLACE 80 F

is equipped with a

nozzle changer for the Pick & Place

head. As standard, it is fitted with

one magazine. This can simultane-

ously hold 4 standard nozzles and

one special nozzle. The changer is

mounted on the right-hand side of

the PCB conveyor with no loss in

feeder locations. As an option, 3

additional nozzle magazines can be

installed for 5 nozzles each. Noz-

zles are exchanged automatically

during the placement sequence.

Description

Full Flip Chip handling capability on

the part of the SIPLACE 80 F

ensured by a flux dispenser in-

stalled directly next to the revolver

head. Immediately before the Pick

& Place head places the Flip Chip,

the mounting location on the PCB

is wetted with low-viscosity flux

by means of a dispensing needle.

The flux dispenser option essen-

tially comprises one stepping mo-

tor with piston, injector and valve

to change the operating mode (fill /

dispense injector) plus one storage

tank. The stepping motor positions

the piston over the storage tank to

be filled or over the Flip Chip

mounting location on the PCB for

emptying.

The purpose of a programmable

waiting time until PCB transport is

to allow the low-viscosity flux suf-

ficient time to dry so that the Flip

Chip(s) will not shift position while

the PCB is being moved out. A

new PCB conveyor control with

adjustable acceleration and delay

ramps makes programming the

waiting time largely superfluous.

Description

On SIPLACE 80 F

placers the in-

line conveyor system guarantees a

quick adjustment to new PCB

widths. The change is made either

at the station via menu function or

from the line computer via the

automatic width adjustment unit.

Ceramic substrates are also trans-

ported and, if necessary, fastened

in place via the optional ceramic

substrate centering unit.

As standard, the SIPLACE place-

ment systems are available with a

single conveyor system.
