PCB Conveyor
Flexible Dual Conveyor
Description
As a result of reduced sec-
ondary processing times and
in conjunction with the opti-
mum placement program,
the PCB dual conveyor can
significantly enhance
throughput times. It allows
two PCBs to be carried si-
multaneously (synchronous-
ly) or alternately
(asynchronously) through
the placement machine.
In asynchronous mode, only
one PCB is processed in
each conveyor lane. At the
same time, another PCB in
the second conveyor lane is
moved into the placement
position. This saves the full
conveying time of one PCB,
thus considerably increasing
performance, particularly for
PCBs with a short cycle time.
The placement process
starts as soon as one PCB is
transported into the process-
ing area.
In synchronous mode, two
PCBs are moved into the
placement position at the
same time. They are pro-
cessed as a common panel.
This facilitates the process-
ing of a board upper and un-
derside in one line. The
amount of nonproductive
secondary processing time is
reduced, as two boards are
always transported at the
same time.
