3.7.2.4 Synchronous transport mode
In synchronous mode, two boards of the same size are transported into the placement position at
the same time. They are processed as a common panel. When using products with greatly differ-
ing placement content, common optimization increases the performance of the whole content on
both boards.
The time needed to transport the board is reduced as two boards are always 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.
If only one conveyor lane is occupied at the beginning of placement, this single use of the con-
veyor lane will be identified as "not to be placed".
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.
3.7.2.5 I-Placement
In addition to synchronous and asynchronous conveyor modes, I-Placement is also available. In
this mode, the two heads work simultaneously and populate a PCB totally independently of one
another. This further increases the output.
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.

3.7.4 IPC-Hermes-9852
IPC-HERMES-9852 is a communication protocol for SMT lines and can replace the IPC SMEMA
interface. This protocol allows you to transfer more information than previously via the IPC
SMEMA interface. This could be, for example:
– Unique board IDs
– Barcodes
– Conveyor speed,
– Board length and width
– Board thickness
– Transport clearance height
All this information can be transmitted along the whole line without interruption. See also the ad-
ministrator manual IPC-HERMES-9852, [item no.: 00198615-xx]
