3.9 X feeder modules for SIPLACE X-Series
SIPLACE X feeder modules are used for SIPLACE X-Series machines. All SIPLACE X feeder
modules are compatible with the SIPLACE X-Series changeover tables. Key properties of the SI-
PLACE X feeder modules include the high precision of the pickup position, online programmability,
status displays on an LCD display and simple handling for feeder module changes during the
placement process. The power supply to the feeder modules is contactless and uses an inductive
interface. Each feeder module communicates with the feeder module control unit (FCU) via two
optoelectronic channels (optical fiber). The two interfaces form the EDIF assembly (energy and
data interface, see item 2 in fig. 3.9 - 1
, page 176 ). The feeder module control unit is connected
to the control unit of the machine via the CAN bus.
3.9.1 Tape feeder modules for the SIPLACE X-Series
3.9.1.1 Tape material
The tape width spectrum for SIPLACE X-Series machines ranges from 4 mm to 88 mm. The tape
material is blister or paper. Component 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)
IEC 60286-3-2 3
