3.8 Feeder modules for SIPLACE E
Key properties of the SIPLACE SmartFeeder E include the high precision of the pickup position,
online programmability, a LED status displays and simple handling for feeder module changes
during the placement process. The power supply and the machine communication to the feeder
modules uses Pogo-pins.
3.8.1 Tape feeder modules
3.8.1.1 Tape material
The possible tape widths range from 8 mm to 56 mm. The tape material is blister or paper. 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
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.
3.8.1.2 Tape reel diameter
The tape reel diameter may be up to 17" (432 mm) for all feeder modules.
Tape width Overall height of the blister tapes
8 mm Max. 3.5 mm
12 mm Max. 16 mm
16 mm and wider Max. 16 mm
