3.15.7.1 Asynchronous Transport

Description 3

In asynchronous mode, only one PCB in a transport track is processed. At the same time, another

PCB in the second transport track is moved into the placement position. This saves the full con-

veying time of one PCB, thus considerably increasing performance, particularly for PCBs with a

short cycle time.

Function 3

Once the machine has received the job data (panel, setup), the PCBs on the feeding belts are con-

tinuously transported to the available processing belt (provided that the processing belt is free)

throughout the placement operation. The placement sequence starts as soon as a PCB has

moved onto the processing belt. The PCBs are processed one after another.

If the placement sequence is interrupted, the conveyor interface will be disabled and the PCBs

currently on the processing belts will be completed.

The conveyor interface is disabled or enabled simultaneously for both transport tracks.

3.15.7.2 Synchronous Transport

Description 3

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 facilitates the processing of a board upper and underside in one line. The time needed for

board transport is reduced as two boards are always transported at the same time. It also ensures

better utilization of the nozzle configuration.

Function 3

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 (or center conveyor) is full when the placement sequence starts, the

subpanel on this section will be identified as “not for placement”.

Restrictions 3

If the dual conveyor is operated in synchronous mode, the ‘PCB whispering down the line’ option

is deactivated. PCB barcode operation is not supported in this mode. The "Global bad fiducial"

option cannot be used.

3.15.8 Dual Conveyor Control with Single Function Menu

The online help contains information on controlling the dual conveyor and on the Single Functions

menu.

3.15.9 Automatic Width Adjustment for Dual Conveyors

When the command is received, the conveyors are set to the desired width one after another. Dif-

ferent widths are possible.

See the Online Help for detailed information about changing the conveyor track width.
