a) All 6 magazines must always be set up.

The number of nozzle changers for the Collect & Place heads depends on the number of gantries

in the placement area:

- up to four nozzle changers may be installed in the placement area with two gantries

- up to three nozzle changers may be installed in the placement area with one gantry

If an SWS is used, CA systems are equipped with a nozzle changer at the relevant SWS loca-

tion. Depending on the placement head used a second bank can be configured.

PCB Conveyor

Single Conveyor

Description

For placement, the PCB is

clamped from below. The

distance between the top of

the PCB and the placement

head thus remains un-

changed for each PCB, and

is not dependent on the

thickness of the PCB. The

placement rate is thus inde-

pendent of the PCB thick-

ness.

Since the distance between

the PCB surface and the

PCB camera remains the

same, the PCB camera is al-

ways focussed on the PCB

surface with the same level

of sharpness.

The PCB fiducial contours

are optimally mapped on the

CCD chip of the PCB cam-

era.

The inline PCB conveyor

system quickly adapts to a

wide range of PCB widths.

The setting is made using the

placement program or via

the station software menu.

The width of the PCB con-

veyor is monitored by an in-

tegral control circuit.

The machine height can be

modified, thus allowing the

machines to be integrated

into lines with a transport

height of 830, 900, 930 or

950 mm.

-The communication be-

tween the PCB conveyors of

the individual machines is via

a SMEMA interface (optional

Siemens interface).

The fixed transport side can

be located on the left or right

for both the dual conveyor

and the single conveyor.

With this conveyor, the fixed

side can be easily switched

from right to left or vice versa.

Movement and clamping of

the PCBs are monitored. If

the board has reached the

placement area and passed

the light barrier, it is braked.

A laser light barrier deter-

mines the position of the

board. As soon as the board

has reached its target posi-

tion, the conveyor belt is

stopped and the board is

clamped from below. The

placement process then

starts immediately.
