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.
