Description

The highly developed Pick & Place

Head operates on the Pick & Place

principle. It is suitable for picking

up particularly sophisticated or

large components as well as non-

standard models. High-resolution,

intelligent vision modules (Fine

Pitch and Flip Chip component vi-

sion modules) ensure that the

components are in satisfactory

condition that the placement posi-

tion is correct.

The sleeve with nozzle is the heart

of the Pick & Place Head. The

sleeve is mounted such that it is

movable in the longitudinal (Z-axis)

and rotational direction (D-axis).

Each of the two axis are driven by

a DC motor; positioning is done by

incremental encoder. Thanks to a

high-resolution glass incremental

panel on the sleeve, the Pick &

Place Head has an outstanding

high rotational position accuracy.

The rotating movement is trans-

mitted directly from D-axis motor

to the driving plate on the sleeve

via frictional wheel.

To the standard Fine Pitch com-

ponent vision module the op-

tional Flip Chip component vi-

sion module can be added to

allow the Pick & Place Head to

place Flip Chips.

Equipped with the DCA-package

SIPLACE F

is optimized in

speed and accuracy for high

speed Flip Chip and bare die

placement. Thus the accuracy

for the Pick & Place head in

combination with the Flip Chip

vision module reaches an accu-

racy of ± 40 µm at 4 sigma.

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.
