Fig. 3.7 - 4 Transport modes
3.7.2.3 Synchronous transport mode
In synchronous mode, two PCBs of the same size are moved into the placement position at the
same time. They must be processed as a common panel.
This allows both the top and the underside of a PCB to be processed on the same line. The time
taken to move the PCBs is reduced as there are always two PCBs being transported at the same
time. It also ensures better utilization of the nozzle configuration.
PCBs on conveyor tracks 1 and 2 are moved synchronously onto the conveyor sections (i.e. the
conveyors are controlled synchronously, but independently of one another). The components to
be placed on conveyor tracks 1 and 2 must be organized into a panel via two subpanels. (See the
SIPLACE Pro user manual).
If only one conveyor track is full when the placement sequence starts, the subpanel on this section
will be identified as "not for placement".
If the dual conveyor is operated in synchronous mode, the ‘PCB whispering down the line’ option
is deactivated. The "Global bad fiducial" option cannot be used.
3.7.2.4 I-placement (SIPLACE X4I only)
Another placement concept has now been developed for the SIPLACE X4I in addition to synchro-
nous and asynchronous transport modes. This is known as I-placement. In this mode, the two
placement heads work simultaneously in one placement area and populate a PCB totally indepen-
dently of one another. Normally the placement heads work in alternating placement mode: while
the placement head is placing a PCB in one placement area, the other placement head picks up

components from the feeder modules. With "I-placement", there are no such waiting times for the
placement heads, which increases the placement rate.
3.7.3 Controlling and width adjustment
3.7.3.1 Controlling using the Single Functions menu
The online help contains information on controlling the PCB conveyor system and on the Single
Functions menu.
3.7.3.2 Automatic width adjustment
When the command is received, the conveyor belts are set to the desired width. Different widths
are possible for a dual conveyor.
*See the Online Help for detailed information about changing the conveyor track width.
