Description

One nozzle changer can be in-

stalled for the 12-nozzle revolver

head on each the left and right of

the PCB conveyor with no loss of

feeder locations. The revolver head

changes the placement quickly and

reliably for the nozzle configuration

required for a particular job. Dam-

aged or faulty nozzles can be ex-

changed via menu function.

Description

On SIPLACE S-23 HM placement

machines the in-line conveyor sys-

tem ensures a speedy adjustment

to new PCB widths. The changeo-

ver is made either at the station via

menu function or from the line

computer via the automatic width

adjustment. Ceramic substrates

are also transported or fixed in

place by means of the optional ce-

ramic substrate centering feature.

As standard the SIPLACE place-

ment system are available with a

single conveyor system.

PCB Transport

Direction

Asynchronous

Synchronous

Description

Thanks to the reduced non-

productive times, the dual PCB

conveyor can effect a considerable

increase in the throughput, de-

pending on the program. It enables

the simultaneous (synchronous) or

alternating (asynchronous) trans-

port of two PCBs through the

placement machine.

In the case of the synchronous

type of transport it is possible, for

example, to process the top and

bottom of the PCB without using

the cluster technique.

In the case of the asynchronous

type of transport one PCB can be

moved into the placement ma-

chine during slack time while an-

other one of the same type is be-

ing populated. The portion of non-

productive time caused by the

transport of the PCB is therefore

completely eliminated. The in-

crease in placement speed to be

expected is between 10% and

30%, depending on component

load of the PCB.

Insofar as the customer is con-

cerned, switching between asyn-

chronous and synchronous dual

conveyor entails relatively little ex-

penditure. The optional ceramic

substrate centering is possible, the

PCB bar code mode is not.
