A nozzle changer for the 6-nozzle

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 place-

ment 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 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 F

is en-

sured by a flux dispenser installed

directly next to the revolver head.

Immediately before the placement

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 F

the in-line con-

veyor 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 auto-

matic width adjustment unit. Ce-

ramic 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.
