3.9 X feeder modules
Important features for the SIPLACE X feeder modules are the high precision of the pick-up posi-
tion, online programmability, status displays on an LCD display and easy handling when changing
feeder modules during the placement process. The power supply to the feeder modules is con-
tactless and uses an inductive interface on the component trolley docking unit. Each feeder mod-
ule communicates with the feeder control unit (FCU) on the component trolley docking unit via two
optoelectronic channels (optical fiber). These two interfaces create the EDIF module (energy and
data interface, see point 2 in Fig. 3.9 - 1
, page 172). The feeder module control unit is, in turn,
connected to the machine's control unit via the CAN bus.
3.9.1 Tape feeder modules for the SIPLACE X-series
3.9.1.1 Tape material
The possible tape widths range from 8 mm to 88 mm. The tape material is blister or paper. Com-
ponent tapes with a permanently adhesive cover foil (PSA foil) can also be processed. This will
require the "PSA Kit" option.
The design of the tape feeder modules was based on the following tape standards:
DIN EN 60286-3 (12/1998) / IEC 60286-3 (12/1997)
JIS C 0806-3 (1999)
ANSI/EIA 481-C (10/2003) 3
The overall height of the blister tapes depends on the tape width, and must not exceed the follow-
ing maximum values:
For 8 mm paper tapes, the paper thickness must not exceed 1.6 mm. The length of a component
-pocket in the direction of travel must not exceed 51 mm.
PSA Kit Item no.

3.9.1.2 Tape reel diameter
The tape reel diameter may be up to 19" (483 mm) for all feeder modules. A list of the maximum
tape reel diameters in relation to the PCB conveyor height can be found in Section 3.10.8.2

3.9.1.3 Manual removal of tantalum capacitors that were not picked up by the
operator
To ensure that tantalum capacitors do not cause the tape material to burn when it is cut as a result
of pick-up errors, the user interface has been extended to include the "Remove component from
tape in the event of a pick-up error" option. This option must be enabled in SIPLACE Pro. On the
placement machine, the component that was not picked up is paced forward again until it is ready
for removal from the component tape. The track is deactivated and the operator is sent an error
message to remind him to pick up the tantalum component from the tape.
If an alternative track is available, the machine continues placing. The operator is able to stop the
machine, however, and pick up the tantalum component.
If no alternative track is available and it is not possible to continue placement with other compo-
nents, the machine will stop. At this point, the operator can again remove the tantalum component
and acknowledge the error. Once the operator has restarted the machine, placement is continued
and components are picked up from the track that is now enabled once more.
PLEASE NOTE 3
This software function is also a good idea for expensive components. Please follow the safety
instructions for capacitors based on powdered metal (see Section 2.5.2, page 64).
